Distance measurement apparatus and distance measurement method

Abstract

A distance measurement apparatus (10) is an apparatus that causes a light receiving unit (180) to detect pulsed-light, which is emitted from a light source (14) and reflected by a target object (30). The distance measurement apparatus (10) includes an estimation unit (121). The estimation unit (121) estimates a peak position of the pulsed-light by using a saturation waveform that is a reception light waveform which is generated by the light receiving unit (180) that receives the pulsed-light and in which a reception light signal is partially saturated. Here, the estimation unit (121) specifies a temporary peak position by using a plurality of data points including a start point of the saturation in the saturation waveform. Further, the estimation unit (121) specifies a correction parameter based on a saturation width of the saturation waveform. The estimation unit 121 estimates the peak position of the pulsed-light by correcting the temporary peak position by using the specified correction parameter.
