And that applies to all the different packages. 2008; Kersten et al. (2011), Muralikrishnan et al. 7). His years of industry instruction allow him to educate teams efficiently while they improve their workflows. For each scan station, the targets were scanned four times each, taking into account the long distances for the resolution. In addition, five laser scanners were tested in accordance with instruction sheet 7-2014 of the German Society for Geodesy, Geoinformation and Land Management (DVW) for standardised testing of terrestrial laser scanners in the outdoor area of HafenCity University Hamburg. Mller (Hrsg. Thus, no significant distance deviation can be detected. The results of the laboratory tests show a high level of accuracy for all scanners, which correspond to the manufacturers specifications. The first scan was started at a distance of 1 m from the scanner position and then continued at intervals of 1 to 20 m each. 13), but this may not be the case everywhere in practice. 3 right). In fact, almost everything about this new device is better! Holst et al. For the IMAGER 5016 (LKA) all deviations are negative, but less than 1 mm; i.e. Therefore, the target fitting was performed in the respective software and the determined target coordinates were exported and entered into the standardised Excel form, which is available with the DVW instruction sheet. (1) for the final evaluation of the instrument (Table 3). colour will take about 4:20 (or 2:50 if no HDR) greyscale will take about 1:50. point accuracy starts at 6-8mm. * All accuracies are specified as maximum permissible errors (MPE) and in accordance with ASME B89.4.19-2006 & IS010360-10 using precision Leica 1.5 Red Ring Reflectors up to 60 m distance unless otherwise noted. (2021) already determined the magnitude and spatial expansion of the resolution capability of the BLK360 amongst nine other TLS. Both targets and spheres could be measured in the software ReCap Pro for all scans of the BLK360. The new generation of our classic standard lens. ), Wichmann, VDE Verlag GmbH, Berlin und Offenbach, 414. What is necessary or sufficient depends on the job to be done. Although the results apply only to the specific instruments in this investigations, they were confirmed in the case of the IMAGER 5016 (HCU) by the tests in 2020.

In 2017 and 2020, the reference distances were measured with the Leica AT960 laser tracker. The measurements were performed for the scanners in 2019 in about 2 h each and in 2020 in about 3 h each, because six additional targets were scanned at right angles to scan station 1 at distances of 5 to 30 m for the determination of uT. The following laser scanners were tested in the lab: Leica BLK360 (2017), Leica RTC360 (2019), Z+F IMAGER 5016 (2019, 2020), Z+F IMAGER 5010 (2020), and Faro Focus 3D X330 (2020). This concerns systematic instrument deviations resulting from the distance measurement or the axis mechanics (Neitzel et al. Now. The deviations of the IMAGER 5016 (LKA) are around zero in both the positive and negative range, which is confirmed by the mean value of 0.07 mm. We also look at the Pro2, Leica BLK360, a set of 360 cameras and Axis, which turns the phone in your pocket into an accurate capture device. Nevertheless, the precision specified by the manufacturer should be checked from time to time in order to be able to guarantee a corresponding specification. Workshop on Scanning for Cultural Heritage Recording, Corfu, Greece, 33-38. https://goobi.tib.eu:443/viewer/image/830281592/36/. The Leica BLK360 captures the world around you with full-color panoramic images overlaid on a high-accuracy point cloud. It captures spaces with the highest accuracy, enabling the most detailed point cloud files. It captures building exteriors, structures, and environments to create 3D point clouds while flying. This aspect is also obvious for these two laser scanners in the spatial distance deviation in the range of 1 mm. However, both the comparison of the spatial distances in the test field and horizontal distances at the comparator track with references demonstrated that outliers are in the scanned data set. This paper summarizes recent research into current terrestrial laser scanners undertaken by the HafenCity University Hamburg and gives an assessment of the geodetic accuracy of the latest generation of scanners. : terrestrial laser scanner Leica BLK360, Leica RTC360, Z+F IMAGER 5010, Z+F IMAGER 5016 in the 3D test field, and b/w target installation.

Everyday carry (EDC) Make your Leica part of your daily routine. The Leica BLK360 captures the world around you with full-color panoramic images overlaid on a high-accuracy point cloud. Only the IMAGER 5010 tends to show deviations in the negative range (mean value 0.5 mm); i.e. Johansson M (2003) Explorations into the behaviour of three different high-resolution ground-based laser scanners in the built environment. The BLK360 seemed like the perfect addition to a company such as ours. The BLK360 G1 is compatible with iPhones and iPads. Terrestrial laser scanner investigated (f.l.t.r. The differences 1.4 and 3.4 are significantly lower at 3.0 mm and 0.2 mm and also do not indicate any errors in the angle measurement. The height has also changed. For the differences 1.4 and 3.4, only small deviations between 0.2 mm and 3.0 mm were determined and thus no significant errors in the angle measurements were detected. Muralikrishnan B, Rachakonda P, Lee V, Shilling M, Sawyer D, Cheok G, Cournoyer L (2017) Relative range error evaluation of terrestrial laser scanners using a plate, a sphere, and a novel dual-sphere-plate target. 10. Gruen/Kahmen), Zurich, July 9-12, Vol. 2007; Mechelke et al. This website is using a security service to protect itself from online attacks. For the three IMAGER 5016 scanners, the difference 1.2 is 1.7 mm, 2.4 mm, and 2.1 mm and is thus significantly below the reference value (2.3 mm/8.0 mm/4.4 mm) for all distances. Kersten T, Mechelke K, Lindstaedt M, Sternberg H (2009) Methods for geometric accuracy investigations of terrestrial laser scanning systems. The resolution for the IMAGER 5016 and 5010 was set to high (6 mm at 10 m) with quality balanced and normal, respectively, whilst for the Faro Focus the resolution was set to 1/5 (7.7 mm at 10 m) with quality 3.

Ingeo 2004, Bratislava, http://www.geometh-data.ethz.ch/downloads/SchulzT_TS2_Bratislava_2004.pdf, Schulz T (2007) Calibration of terrestrial laser scanner for engineering geodesy. Then, the coordinates of each measured target are averaged and the distances TiTj between the targets are calculated for both scan stations: Since all scanned distances are available twice due to two scan stations, differences \({\Delta }_{ij}\) can be calculated from each of the two distances, which were summarised in Table 3: The results of the field test procedure are summarised in Table 3 for five laser scanners investigated in accordance with the calculation form of the DVW instruction sheet. 12. Photogrammetrie, Laserscanning, Optische 3D-Messtechnik - Beitrge der Oldenburger 3D-Tage 2011, Th. The reference measurements were realised with the Leica Absolute Tracker AT960 (2017, 2020) and with the Leica TS60 total station (2019). . In addition, different amounts of data were generated in the various test scenarios (Table 5). Automatically located and tracked by PowerLock, reflectors allow high-speed dynamic measurement in volumes of up to 120 m (). The Gen 2 is not only smaller but is much faster than its predecessor. The scanned points belonging to the slab were cropped and a best-fit plane was calculated through all unfiltered point clouds using GOM Inspect software (V8 SR1). HafenCity University Hamburg (HCU) has been investigating terrestrial laser scanning systems for more than 15 years; since 2016, a more accurate test site has been established at the new building of HCU Hamburg, which can serve as a reference for the increased accuracy level of the new scanners. The measurement setup for checking the distance measurement accuracy of terrestrial laser scanning systems is illustrated in Fig. The Right Software to Advance Your Business. Using the Control key to modify how polylines are selected in AutoCAD or Civil 3D, Using the Shift key to modify the functionality of the FILLET command in AutoCAD or Civil 3D. 2014). The RTC360 delivers the highest value of all scanners for the distance difference 1.2 with 6.0 mm, but this value is still no indication of a distance deviation because the decisive comparison variable has the same value. The other major feature I would like to discuss here is the addition of VIS to the Gen 2. The distances calculated from the centre coordinates were compared with the spatial distances of the reference measurement and the differences were plotted in a frequency diagram (Fig. Results (2019) of the flatness measurement error in a table (left) and in a diagram (right). In the field test procedure, two additional Z+F IMAGER 5016 and a Faro Focus3D X330 were tested in 2020, in addition to the Z+F IMAGER 5016 and Leica RTC360 terrestrial laser scanners in 2019. For the first time, three laser scanners of the same type (Z+F IMAGER 5016) could be examined and compared. Now in its third generation, this ABSOLUTE ACCURACY THE RIGHT WAY TO MEASURE WHATEVER THE APPLICATION Driven by the absolute distancing capabilities of the AIFM, the Leica Absolute Tracker AT960 is capable of exceptionally accurate readings across several inspection methods. Use the up and down arrows to select a result. VDI/VDE guideline 2634, part 3, Beuth Verlag, Berlin. For the laboratory and field investigations, a selection of current and innovative laser scanning systems were available from 2017 to 2020 (Fig. Issues with Profile Views after Station Adjustment. Here's the breakdown: Reality capture data connectivity with Autodesks design solutions. The distance accuracy of terrestrial laser scanning systems was investigated on the 20-m comparator track in the geodetic laboratory at HCU Hamburg. 360,000 laser scan pts/sec ReCap Pro Software: Gain complete access to ReCap Pro for desktop, web, and mobile* Control all aspects of the reality capture process remotely on ReCap for iPad Automatically register and visualize scan data in the field Mark up, tag and collaborate on scans while on the job site In addition, we thank our colleague Klaus Mechelke (HCU Hamburg) for the reference measurements of the 3D test field with the laser tracker Leica AT960 in 2017 and 2019. 2009, 2011, 2012), which allow statements about the accuracy behaviour and the application potential of terrestrial laser scanner systems to be made. Featuring VERSATILE AND RELIABLE FOR ANY INDUSTRY Every industry has specialist metrology requirements. (2018) to improve the quality of TLS point clouds. The scanners look similar but if we inspect a little closer, there are some major differences. Arch. As many of you know, Leica released the BLK360 Gen 2 last year. Finally, it must be mentioned that the investigations took place at a very early stage of software (ReCap Pro) and hardware (Leica BLK360) development. Pawowicz JA (2018) Impact of physical properties of different materials on the quality of data obtained by means of 3D laser scanning. Lets take a few minutes to explain what some of the changes and how they might affect your HDS workflow. Critical aspects were also identified during the investigations. The technical specifications of all tested scanners are summarised in Table 1. Spat. Thus, with the Leica RTC360, the highest resolution level (3 mm at 10 m) was selected in each case and an all-round scan was performed; on the other hand with the IMAGER 5016, only section scans of the targets were scanned with the highest resolution of 1 mm at 10-m distance after a full panoramic scan. For the execution of the field test procedure, only the standard equipment and software of the respective manufacturers were used. BLK360-What-is-the-accuracy-of-the-camera-alignment. For a scanner this size that is truly remarkable! ), Vol. (2007), Gordon (2008), Gottwald (2008), Feldmann et al. These outliers could be addressed to an unreliable automatic target fitting in the ReCap Pro software or errors in the scanning instrument. Mechelke K, Kersten T, Lindstaedt M (2008) Geometrische Genauigkeitsuntersuchungen neuester terrestrischer Laserscanningsysteme - Leica ScanStation 2 und Z+F IMAGER 5006. Nevertheless, the constant and systematic distance measurement deviation with 1.1 mm (1.2/2) does not give any indication of a distance deviation, since the comparison variable has a high value of 13.2 mm. Innovation stories Reality capture for all Hexagon disrupts its own disruptive technology with the all-new Leica BLK360 laser scanner. the distances are measured slightly too long. Why Leica Service? This image is a stock photo Leica has on their website so I would like to just show some data I have collected personally. Terrestrisches Laser-Scanning (TLS2006). Android devices are not currently supported. Kersten T, Sternberg H, Mechelke K (2005) Investigations into the accuracy behaviour of the terrestrial laser scanning system Mensi GS100. After scanning in the field, only the 3D coordinates of each scanned target are required. Institutions such as the Hamburg State Office of Criminal Investigation have their terrestrial laser scanners checked annually at HCU as part of their required quality management system certification. the distances are generally minimally too short. Parameter of the two triangles according the setup of the field test procedure (see Fig. In 2019, the reference distances were measured with a Leica TS60 total station, with an accuracy of 0.6 mm + 2 ppm according to the manufacturer specification when measured on a corner cube reflector. They are more powerful than 3D polylines and allow for curves in design delineations. Synchronization is very slow, After 15 . However, for testing laser scanning systems, these special adapters allow the installation of a b/w target on each point nest (Fig. DVW-Schriftenreihe 51:314. But, not all of the scanned distances are within this specification as illustrated in Fig. Thus, the procedure according to DVW instruction sheet is manufacturer-independent and provides an opportunity to compare the manufacturers specifications with the accuracies achieved in the field test procedure. This procedure has been published in its extension 2018 as ISO 17123-9, which now also considers test procedures for terrestrial laser scanners with this part 9.

It may thus be difficult for users to choose the right scanner for a specific application, emphasising the importance of comparative investigations into accuracy behaviour of terrestrial laser scanning systems. BLK360. So, if you have a need to collect temperature data for your scans, the G1 may be the way to go. colour will take about 1:30 (RTC always does HDR) greyscale will take about 0:30. point accuracy starts at 2-3mm. In contrast, the curve of the RTC360 is somewhat flatter and wider, and the span is twice as large at 8.0 mm. Blaze through job sites with rapid scanning that doesn't compromise on quality. In contrast to the BLK360, all scanners show small deviations from the reference between 1.0 mm and +1.6 mm.

Your IP: 2012), it has a significantly smaller measurement volume and extends over only one floor. Terrestrisches Laser-Scanning (TLS2006). Additional integrated sensors such as an inclination compensator and camera, as well as extensive software, make the systems flexible and efficient to use. (2003). In general, the terrestrial laser scanning systems should be always considered as a complete system consisting of hardware and software (with the corresponding algorithms for point cloud processing). Through the development of the DVW instruction sheet 07-2014, standardised field test procedures for the testing of laser scanners have been created, which are possible for all users and require a limited amount of time. Nevertheless, a systematic effect could be detected, since the scanned distances of the BLK360 were too short in both, in the test field and at the comparator track. The scan resolution of each of the IMAGER 5016 and 5010 was set to high with quality normal (6 mm at 10 m), for the Faro Focus the resolution was 1/5 with quality 3 (7.7 mm at 10 m), and for the BLK360 and RTC360 the highest level was chosen (5 mm at 10 m and 3 mm at 10 m, respectively). Photogrammetrie, Laserscanning, Optische 3D-Messtechnik - Beitrge der Oldenburger 3D-Tage 2018, Th. However, the fitting of the target was only possible up to a distance of 15 m, whilst the fitting of the sphere could only be performed up to a distance of 18 m due to an insufficient scan resolution. However, it was not possible to judge whether the poor target fitting in the software is directly responsible for the inaccurate distance determination or whether there are instruments errors. FIG Working Week 2008, Stockholm, Sweden. An overview of the site with the installed targets (blue circles) and scanner stations (red circles) is illustrated in Fig. Optimize Your Design Process for Greater Efficiency. ): Leica BLK360, Leica RTC360, Z+F IMAGER 5010, Z+F IMAGER 5016, and Faro Focus3D X330.
