BP-32, the LiDAR scanning backpack

Design

What’s inside BP-32

1. Sensor head above the operatorThe LiDAR scanner, GNSS/RTK antenna and four cameras sit on a mast, so they see the surroundings above obstacles and above the operator.
2. Electronics caseThe lid opens forward. Inside: a computing unit with a 128 GB drive and a swappable 190 Wh V-mount battery — about 4 hours of continuous work.
3. Sensors that work togetherLiDAR measures distances, GNSS/RTK provides the position in the project system and the IMU records motion and tilt 1000 times per second. The cameras add 360° panoramas.
4. Scanning behind the operator, on the moveThe head is tilted backwards, so the 32 beams scan the ground behind the operator rather than the operator. They spin 20 times per second — up to 640,000 points per second — and the point cloud builds up as you walk.
