Patent attributes
A laser radar device includes: a light-transmission-side lens that shapes a laser beam emitted from a laser light source into a line shape extending along a horizontal direction; a scanner that projects the line-shaped laser beam while scanning the same in a vertical direction of a measurement-target area; a light-reception-side lens that receives reflected light reflected from the measurement-target area; a light reception line sensor including a plurality of light reception cells lined up along the horizontal direction; a light-reception-side optical system that gathers the reflected light received by the light-reception-side lens toward the light reception line sensor, and in which the light-gathering ratio in the vertical direction is set so as to be greater than the light-gathering ratio in the horizontal direction; and an information generation unit that generates three-dimensional information of the measurement-target area based on a reception signal outputted by the light reception line sensor.
