Abstract
A laser radar device includes a scanner unit for scanning a measurement target area along a second direction orthogonal to a predetermined first direction by irradiating the measurement target area with a line-shaped laser beam as a light-transmitting angle is changed, the line-shaped laser beam being a laser beam formed into a line shape so as to extend in the first direction, a received signal generation unit for generating a received signal according to received reflected light of the line-shaped laser beam, a storage unit for storing shape distortion information of the line-shaped laser beam in the second direction, and a three-dimensional information generation unit for generating three-dimensional information of the measurement target area based on corrected position information in the second direction obtained by correcting position information in the second direction calculated based on the received signal and the light-transmitting angle, with the shape distortion information.
