The paper contains explanation such as the depth measurement, lasers, laser sensor, and radial offset. Inside the paper we can find explanation related to sensor, measurement, and laser beams.
Lots of explanation around sensors, laser sensors, and depth measurement are presented inside this paper. The following are grabbed from this paper:
Laser sensors are widely used for precision measurement of the distances. They all include one or more laser sources and one or more cameras and, using triangulation, they provide a precise measurement of the distance between the sensor (laser(s) plus camera(s)) and the target. The principle is simple: the laser creates a light spot on the target, while the camera takes a snapshot of the spot. Measuring the position of the spot projection in the image, the distance to the target can be measured. The first part of this paper presented already a set of new geometries for laser sensors, so that the location of each laser plane projection is uniquely determined in the projection plane .
Giving more content, the paper presents discussion things like laser, depth measurement precision, and measurement precision.
