Abstract
A technique for solving problems in laser scanning related to intense light that is reflected back from a reflector target is provided. A laser scanning control device for controlling laser scanning performed by a laser scanning apparatus includes a controller, a distance acquisition unit, and a light controller. The controller executes first laser scanning and second laser scanning. The first laser scanning is performed under conditions in which a detector of the laser scanning apparatus is saturated by light reflected back from each of reflection prisms. The second laser scanning is performed under conditions in which saturation of the detector of the laser scanning apparatus does not occur. The distance acquisition unit acquires distances to the reflection prisms based on the first laser scanning. The light controller adjusts intensity of light to be detected in the second laser scanning, based on the distances to the reflection prisms.
