OBJECT DETECTION DEVICE, SENSING DEVICE, MOVABLE BODY DEVICE, AND OBJECT DETECTION METHOD

摘要

An object detection device includes an optical scanning system, a detection system, and a processing device. The optical scanning system includes a light source, a light source drive unit, and a deflector, and causes the deflector to scan a scan area with light from light source at scan positions. The detection system detects the light emitted from the optical scanning system and reflected by an object. The processing device calculates distance information indicating a distance to the object based on a light emission timing and a light detection timing. In a plurality of scans, the optical scanning system causes the light source to emit light at a different scan position in each scan. The processing device includes a correction system to correct the distance information at at least one scan position at which the light source is caused to emit light in at least one scan of the scans.

1. An object detection device comprising:
an optical scanning system that
includes a light source, a light source drive unit configured to drive the light source, and a deflector configured to deflect light from the light source, andcauses the deflector to scan a scan area with light from the light source at a plurality of scan positions of the deflector; a detection system that detects the light emitted from the optical scanning system and reflected by an object; and a processing device that calculates distance information indicating a distance to the object based on an emission timing of the light source and a detection timing of the detection system, wherein in a plurality of scans, the optical scanning system causes the light source to emit light at a different scan position of the deflector in each scan, the processing device includes a correction system configured to correct the distance information at at least one of the plurality of scan position at which the light source is caused to emit light in at least one scan of the scans.
