Laser Scanning Equipment

There are three terrestrial laser scanning equipments for scanning the indoor or outdoor environment which are BLK2GO, RTC360 and Backpack Lidar as shown in Figure 1.

Handheld-BLK2GO RTC360 Backpack Lidar
Accuracy 10m±1cm

10m±1.9 mm



  • Convenient to use
  • Acquire data quickly
  • Can collect the closed indoor structure through the glass
  • Get point cloud data is fast
  • High accuracy
  • Convenient to use
  • Easy to borrow device
  • Wide scanning range
  • The resolution is lower than RTC360
  • Time to get point cloud data is slow
  • Device is heavy
  • Output data is slow
  • Need to be exported with special software (only one License)
  • Heavy

According to our project requirements, the error is 1cm, so we used handheld-BLK2GO for scanning first. The BLK2GO is a handheld imaging laser scanner that creates a 3D digital twin while you walk through a space. It is the fastest and easiest way to scan a large building, structure or environment.

LiDAR 3D scanning system- Backpack Lidar

Backpack Scanner with the function of collecting high-precision geographic coordinate information point cloud and panoramic image. With the help of GPS positioning information, combined with lidar and Simultaneous Localization And Mapping (SLAM) technology, the Lidar Backpack DGC50 backpack lidar scanner can obtain laser point clouds and panoramic image data with high-precision geographic coordinate information. Users can simply wear this lightweight backpack and walk around the area being mapped. The System rapidly collects data to produce 3D maps with centimeter-level precision.

The MMS model is ‘Leica Pegasus TRK NEO500’ and here are some brief descriptions:


Smart 3D reality capture must be kept up to date. The new Leica Pegasus TRK Neo500 is an example of the next level of mobile mapping systems, one that addresses many of the challenges this geospatially charged future poses. High precision 3D reality capture data for road and rail corridors is essential for infrastructure and asset management and even more so for the nascent autonomy market.
