From this measurement uncertainty uT, the comparative quantity of the distance differences was derived according to Eq. 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. 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. https://doi.org/10.1007/978-3-030-51953-7_7, Schulz T, Ingensand H.

(2006): Investigation and calibration of pulsed time-of-flight terrestrial laser scanners. 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. 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. 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. These outliers could be addressed to an unreliable automatic target fitting in the ReCap Pro software or errors in the scanning instrument. 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). 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. Simplified Data Collection Its measured global accuracy is 6 mm. Expectations for model fidelity and measurement accuracy can vary depending on this context. Lindstaedt M, Kersten T, Mechelke K, Graeger T (2012) Prfverfahren fr terrestrische Laserscanner Gemeinsame geometrische Genauigkeitsuntersuchungen verschiedener Laserscanner an der HCU Hamburg. 2008; Kersten et al. ABSOLUTE ACCURACY. Simple to use with the single push of one button, the BLK360 is the smallest and lightest imaging laser scanner. The Leica BLK360 is a lightweight, compact laser scanner that captures 360-degree images and full-color panoramic photos. On the other hand, the maximum is not shifted from zero, 160 values were classified to zero here. 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. Automatically located and tracked by PowerLock, reflectors allow high-speed dynamic measurement in volumes of up to 120 m (). Terrestrial laser scanner investigated (f.l.t.r. 4). The targets were each measured from three different stations, transformed, and then averaged. Inter. Critical aspects were also identified during the investigations. That is a significant increase in scan times! An overview of the site with the installed targets (blue circles) and scanner stations (red circles) is illustrated in Fig. The remaining targets could not be successfully fitted due to the scan resolution and the long distances in the test field. 2011) according to the DVW instruction sheet. Unfortunately, supply chain issues limited the amount of people who were receiving them for a while. Open Access funding enabled and organized by Projekt DEAL. Abbas MA, Setan H, Majid Z, Chong AK, Idris KM, Aspuri A (2013) Calibration and accuracy assessment of Leica ScanStation C10 terrestrial laser scanner. Just wanted to hear some thoughts from others on the Leica BLK360 unit. For this reason, further investigations should be carried out with other scanners of the same type in order to validate the results obtained here. (2003), Johansson (2003), Schulz and Ingensand (2004), Tauber (2005), Heister (2006), Neitzel (2006), Bttner and Staiger (2007), Wehmann et al. The technical specifications of all tested scanners are summarised in Table 1. With the largest dedicated service team of any metrology equipment manufacturer, the customer experience does not end at purchase. DVW-Schriftenreihe 93:940. Anyone who can operate an iPad can now capture the world around them with high-resolution 3D . 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. Kersten T, Sternberg H, Mechelke K (2005) Investigations into the accuracy behaviour of the terrestrial laser scanning system Mensi GS100. For both Leica scanner, RTC360 and BLK360, the highest possible scan resolution was selected (3 mm at 10 m and 5 mm at 10 m, respectively). His years of industry instruction allow him to educate teams efficiently while they improve their workflows.

The reference measurements were realised with the Leica Absolute Tracker AT960 (2017, 2020) and with the Leica TS60 total station (2019). The absolute deviation (span of signed distances between the scanned points on the stone slab) increases from 1.1 mm for the lowest resolution to 3.3 mm for the highest resolution. A deviation of maximum 1 mm was observed for the IMAGER 5016 in 93.1% and 92.4%, for the RTC360 in 77.6%, for the IMAGER 5010 in 75.7%, for the Faro Focus in 40.5%, and in only 21.2% of all values for the Leica BLK360 (Table 2). 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 Focus3D X330 (2020). How it Works Use the Leica BLK360 G1 and the Matterport Capture app to create one unique Matterport model of a site. Arch. The test field used was set up in 2016 in the geodetic laboratory of the new building of HCU Hamburg. The Leica RTC360 3D reality capture solution empowers users to document and capture their environments in 3D, improving efficiency and productivity in the field and in the office through fast, simple-to-use, accurate, and portable hardware and software. Using the Shift key to modify the commands TRIM and EXTEND within AutoCAD and all AutoCAD vertical products such as Civil 3D. When it comes down to it what we all look for in a scanner is accuracy, right? In contrast to the BLK360, all scanners show small deviations from the reference between 1.0 mm and +1.6 mm. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. Using the framework of well-defined test scenarios, suitable test objects (artefacts) are employed to determine quality parameters. For more information please read our Privacy Policy. 2013). Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. The results of the laboratory tests show a high level of accuracy for all scanners, which correspond to the manufacturers specifications. Leica RTC360 vs. Leica BLK 360 - Laser Scanning Forum In the investigations, very good accuracies were achieved for all Z+F IMAGER 5016 tested, which also performed slightly better than the Leica RTC360 in all 2019 test scenarios in the laboratory (3D test field, 20-m comparator track, and planar stone slab). Scanning is simple, regardless of whether you are more familiar with Matterport Pro3/Pro2/Pro or the Leica BLK360 G1. The higher number of points for the RTC360 is probably due to the combined measurement procedure of time-of-flight and phase shift. Featuring VERSATILE AND RELIABLE FOR ANY INDUSTRY Every industry has specialist metrology requirements. Leica BLK360 G1 - RPG Squarefoot Solutions Of the maximum 760 distances for four viewpoints, 613 distances were evaluated for the IMAGER 5016 and 666 distances for the RTC360. Workshop on Scanning for Cultural Heritage Recording, Corfu, Greece, 33-38. https://goobi.tib.eu:443/viewer/image/830281592/36/. Furthermore, the target thickness of 2.03 mm and the radius of the CCR 19.05 mm must be taken into account and added to the offset calculated from the measurements. With the Faro X330, the distance differences 1.2 and 1.4 are in the level of the two IMAGER 5016 tested in 2020, but the difference 3.4 is the highest of all scanners at 11.1 mm. A regular examination of the same scanners will then also allow statements to be made about the long-term stability of the scanners examined. 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. Photogramm. For the laboratory and field investigations, a selection of current and innovative laser scanning systems were available from 2017 to 2020 (Fig. LiDAR Scanner A small, light, fast 3D scanner from Leica that is highly accurate, easy to use, and provides fantastic results.

Leica BLK2FLY Autonomous Flying Laser Scanner The height has also changed. The smallest and lightest imaging laser scanner available. Automatic Target Lock PowerLock provides intelligent targeting to automatically locate the reflector or probe for the easiest laser tracker operation yet. 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. However, the length of the laboratory results in reference distances up to 35 m. The test field consists of 20 signalised b/w targets distributed on walls and ceiling in the laboratory (Fig. It has a range of up to 60 meters and can capture up to 360,000 points per second. 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). 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.
