The Henning-Voscherau-Platz in front of the HCU building was a suitable environment for the required measurement setup according to the DVW instruction sheet (horizontal and vertical triangle; see Fig. Of the maximum 760 distances for four viewpoints, 613 distances were evaluated for the IMAGER 5016 and 666 distances for the RTC360. 2009; Lindstaedt et al. So, if you have a need to collect temperature data for your scans, the G1 may be the way to go. Here, the conditions are available to meet all the requirements specified in the DVW instruction sheet as far as possible (Fig. 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. by Mamula Thu Jan 21, 2021 12:17 pm. Only the IMAGER 5010 tends to show deviations in the negative range (mean value 0.5 mm); i.e. 2023 Leica Geosystems AG - Part of Hexagon, Cyclone REGISTER 360 is now available with BLK360. Photogramm. For the measurements to the spheres, the result looks a bit different (Fig. Due to the high scanning speed, this did not result in a significantly longer scanning time, but the data volume of the RTC360 acquired in all three tests in the lab was more than 100 times larger than that of the IMAGER scanners. Scanning is simple, regardless of whether you are more familiar with Matterport Pro3/Pro2/Pro or the Leica BLK360 G1.

Technische Universitt Darmstadt, https://tuprints.ulb.tu-darmstadt.de/id/eprint/1206. - 213.251.185.168. The results of the laboratory tests show a high level of accuracy for all scanners, which correspond to the manufacturers specifications. Follow Following Unfollow. 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. After the laboratory tests presented above, the two TLS systems (IMAGER 5016 and Leica RTC360) were subjected to the field test procedure in 2019, on the one hand to prove their suitability for use, and on the other hand to implement the field test method at the HCU Hamburg and to set up a suitable setup at a suitable location for future investigations. Create a Digital Terrain Model from a LIDAR point cloud. BLK360-What-is-the-accuracy-of-the-camera-alignment. 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). 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). 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). the distances are then measured minimally too long. You can email the site owner to let them know you were blocked. For the RTC360, on the other hand, the three results of the span between 4.3 mm and 4.6 mm are almost identical or systematically constant (Fig. The Leica BLK360 captures the world around you with full-colour panoramic images overlaid on a high-accuracy point cloud. 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. Based in Stuttgart, Germany, Olaar specialise in architecture, construction and design for a range of indoor and outdoor projects including residential and commercial construction, urban development and concept studies for future builds. With this movable sledge, distances of 1 to 20 m in meter intervals are realised. Photogrammetrie Laserscanning Optische 3D-Messtechnik, Wichmann, Heidelberg: 98107. The other advantage to the Gen 1 is distance. 10 shows a clear linear relationship between increasing scan resolution (or number of points) and flatness measurement error for the IMAGER 5016 (LKA). For a scanner this size that is truly remarkable! Leica Summilux-M 50 f/1.4 ASPH. Zeitschrift fr Geodsie, Geoinformation und Landmanagement 2:8896.

The reduction in the weight of the tracker has significantly reduced shipping costs whilst guaranteeing the very best in precision. Chris Charnley, Quality Manager, Red Bull Racing, The portable Leica Absolute Tracker has enabled us to grow our metrology capabilities at the circuit, no matter where in the world were racing. Cloud Connectivity The BLK360 is easy to use, with a one-button interface that makes it accessible to non-technical users. Augmenting proven technology with new innovations, the AT960 is a sophisticated yet userfriendly walk-around coordinate measuring machine (CMM) that fits in just one flight case. Due to occlusions in the test field, not all targets could always be scanned in each scan, but in general there were between 16 and 18 targets visible in the scans. The initial results of the investigations of the Leica BLK360 on this test field have already been published by Blaskow et al. Distance measurement accuracy on the 20-m comparator track for Leica BLK360 scans to both b/w target and sphere. 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. Kersten T, Sternberg H, Mechelke K (2005) Investigations into the accuracy behaviour of the terrestrial laser scanning system Mensi GS100. Photogrammetrie, Laserscanning, Optische 3D-Messtechnik - Beitrge der Oldenburger 3D-Tage 2012, Th. Leica BLK360. An overview of the site with the installed targets (blue circles) and scanner stations (red circles) is illustrated in Fig. The test field used was set up in 2016 in the geodetic laboratory of the new building of HCU Hamburg. $ 19,087.00 The BLK360 G1 is designed to help new-to-LiDAR users capture point clouds and unlock the potential of using them in many different applications. For example, the Gen 2 has more lenses (cameras for VIS system) and an enclosed mirror so we can no longer accidentally touch the mirror while handling the scanner. Lets take a few minutes to explain what some of the changes and how they might affect your HDS workflow. Mechelke K, Kersten T, Lindstaedt M (2007) Comparative investigations into the accuracy behaviour of the new generation of terrestrial laser scanning systems. When it comes down to it what we all look for in a scanner is accuracy, right?

Furthermore, the sphere fitting failed at a distance of only 1 m, presumably due to the short distance. Both scanners (IMAGER 5016 and RTC360) have a specified distance measurement accuracy of 1 mm + 10 ppm and an angular accuracy of 0.004 and 0.005, respectively. Photogrammetrie Laserscanning Optische 3D-Messtechnik, Wichmann, Heidelberg: 317328. The AT960 brings together functionality and usability, creating an ultra-portable coordinate measuring machine that fits in a single box. the distances are measured slightly too long. Luhmann/Ch. Leica BLK360 G1 - RPG Squarefoot Solutions Just wanted to hear some thoughts from others on the Leica BLK360 unit. https://goobi.tib.eu/viewer/image/856489115/703/. A very similar behaviour, but with a slightly better result, was confirmed for the IMAGER 5016 (HCU) and for the IMAGER 5010 with the span of 0.7 mm/0.6 mm for middle resolution and 1.5 mm for ultrahigh resolution and 0.9 mm for superhigh resolution, respectively, in 2020. The b/w target or sphere (199-mm diameter) is mounted on a carriage together with a corner cube reflector for the reference measurements. Gordon B (2008) Zur Bestimmung von Messunsicherheiten terrestrischer Laserscanner. Whilst this parameter was derived in 2019 for the two scanners investigated from the technical specification of the manufacturers, the measurement uncertainty uT of the three scanners was determined in 2020 from multiple measurements of the target centres and a resulting standard deviation of each target centre coordinates (Table 3). The Leica BLK2FLY is an autonomous flying laser scanner with advanced obstacle avoidance for easy reality capture from the sky. Bttner E, Staiger R (2007) Erste Untersuchungen des Laserscanners IMAGER 5006 von Zoller+Frhlich. 2008; Kersten et al. In addition to the distance and angular precision of the scanner, the algorithm for target fitting in the respective software also influences the result. Kersten T, Mechelke K, Lindstaedt M, Sternberg H (2009) Methods for geometric accuracy investigations of terrestrial laser scanning systems. The measurement setup for checking the distance measurement accuracy of terrestrial laser scanning systems is illustrated in Fig. Red circles = scanner stations, blue circles = target positions. VDI/VDE (2008) Optical 3D-measuring systems multiple view systems based on area scanning. The scanners measure the spatial distances between 0.3 mm longer and 0.6 mm shorter on average, whilst the BLK360 shows a systematic effect and scans the distances 5 mm shorter on average (Table 2). The field test procedure took half a day for each of the scanners.

Heister H (2006) Zur standardisierten berprfung von terrestrischen Laserscannern (TLS). Photogrammetrie - Fernerkundung - Geoinformation, Heft 4, 301316. The standard deviation of the Z+F IMAGER 5016 with maximum 0.36 mm is lower than that of the RTC360 with maximum 0.65 mm, but both scanner are well below 1 mm. As expected, no significant distance or angle deviations were detected in any of the measurement systems, so that the tested laser scanners are ready-to-use, taking into account the measurement volume recorded. I, 122131. The Leica BLK360 G1 is for professionals in architecture, engineering, and related industries. DVW-Schriftenreihe 54:111124. * 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. The first paper about terrestrial laser scanner evaluation was published by Boehler et al. Materials today: proceedings 5(1):19972001. Nevertheless, the precision specified by the manufacturer should be checked from time to time in order to be able to guarantee a corresponding specification. (2011), Muralikrishnan et al. . 4). In fact, almost everything about this new device is better! I have some questions, Please help. Dissertation. Simple to use with just the single push of one button, the BLK360 is the smallest and lightest of its kind. Learn how edits to corridors targets might cause them to become reset or lost. We undertake measured building surveys on behalf of Architects, typically producing plans, elevations and sections etc. Those issues also limited the interest in the new BLK. The Leica BLK360 is a lightweight, compact laser scanner that captures 360-degree images and full-color panoramic photos. In addition, different amounts of data were generated in the various test scenarios (Table 5). 159.65.174.15 Kern F (2008) Prfen und Kalibrieren von terrestrischen Laserscannern. You must have a Professional Plan or higher to upload scans taken with the BLK360 G1 camera. These outliers could be addressed to an unreliable automatic target fitting in the ReCap Pro software or errors in the scanning instrument. Performance & security by Cloudflare. Pricing Leica's scanners are known to be expensive, so before digging too much into the technical merits of each scanner, it was important to know how much more it would cost to get up and running with the Leica suite cost compared to FARO. Lets set aside the technical specifications for a moment and lets talk about data. 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 AT960 brings together functionality and usability, creating an ultra-portable coordinate measuring machine that fits in a single box. 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. Step into your future, your new career is only a click away. 7). Now. The one-button Leica BLK360 is not only the smallest and lightest of its kind, but also offers a simple user experience. However, since the results of the field test procedure depend on the measurement uncertainty uT or on the reference quantity u, it would be desirable if the system manufacturers would clearly specify this value in their technical specifications. 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). ABSOLUTE SPEED DYNAMIC FEATURES TO MEASURE AND GO Metrology equipment should help complete a task quickly, not slow down the process. 2011) according to the DVW instruction sheet. In addition, no errors in the angle measurement are displayed in the calculation form. Johansson M (2003) Explorations into the behaviour of three different high-resolution ground-based laser scanners in the built environment. Whilst the distance measurement of the IMAGER 5016 is based on the phase difference method, the Leica RTC360 uses a combination of phase difference and time-of-flight methods. This flexible functionality and customisable operation allows operators to select the best method for each application and never compromise accuracy. For the IMAGER 5016 (LKA) all deviations are negative, but less than 1 mm; i.e. The verification of terrestrial laser scanners in the laboratory or in the test field is a method of device verification that is not possible for every user.

These are partly identical to the deviations of a total station, but cannot be eliminated by a full set evaluation (Holst et al. Developments in Multidimensional Spatial Data Models, Springer, Berlin, Heidelberg, 3347. The terrestrial laser scanners were placed in front of a stone slab at a distance of approximately 10 m to scan the planar surface under constant laboratory conditions at different resolutions (Fig. 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. In 2020, three additional IMAGER 5016s (2 LKA and 1 HCU) were tested in addition to HCUs two older Faro Focus3D X330 and IMAGER 5010 laser scanners.
