Principle of operation
3.6.1
Measurement principle
The device is an opto-electronic LiDAR sensor (laser scanner) that uses laser beams for
non-contact scanning of the outline of its surroundings on a plane. The device mea‐
sures its surroundings in two-dimensional polar coordinates, relative to its measure‐
ment origin. Its measurement origin is marked by a circular indentation in the center of
the optics cover. If a laser beam strikes an object, the position of that object is deter‐
mined in terms of distance and direction.

3.6.2
Distance monitoring application
The SensorApp developed for the DistanceGuard application uses the 2D measurement
data of the 2D LiDAR sensor for creating distance clusters and identifying people from
a defined object width. To do so, first an area is defined and the background is hidden.
The algorithm is able to assign arms and legs to a person, preventing multiple counting.
