Kind Code:
A
Abstract:
To provide a technology that solves the problem pertaining to strong reflected light from a reflector target in a laser scan.SOLUTION: Provided is a laser scan control device 500 for controlling a laser scan by a laser scan device 200, comprising: a control unit that causes a first laser scan which is carried out under a condition that a detection unit of the laser scan device 200 is saturated and a second laser scan which is carried out under a condition that no saturation occurs to be executed by reflection from reflection prisms 300 and 40; a distance acquisition unit that acquires the distance to the reflection prisms 300 and 400 on the basis of the first laser scan; and an adjustment unit that adjusts the intensity of detection light in the laser scans, on the basis of the distance to the reflection prisms 300 and 400 acquired by the distance acquisition unit in the second laser scan.SELECTED DRAWING: Figure 1
