The invention discloses a calibration method for an imaging auxiliary angle of
LiDAR equipment. The method comprises the steps that: an image of a spatial resolution graph on a flat plate is received, wherein the image is shot by a camera and located at a preset distance from the spatial resolution graph; the
angular resolution of the camera is determined according to the image of the spatial resolution graph and the preset distance; an image of a
laser spot irradiating a
raster scan pattern on the flat plate is received, wherein the
laser spot is emitted from the
LiDAR equipment located at a preset distance from the flat plate, the
raster scan pattern is formed based on a preset
value set in the
LiDAR equipment; then, based on the image of the
laser point and the
angular resolution of the camera, a step-by-step movement angle set of the LiDAR equipment corresponding to the preset
value set is calculated. Angle calibration is thereby performed to ensure that the
solid state LiDAR equipment has an accurate and reliable expected
scan angle.
