Original Abstract Submitted
A light distance measurement device detects a distance to a target. The light distance measurement device includes an irradiation unit, photodetectors, a level adjustment unit, a peak detection unit, a pulse information acquisition unit, and a distance calculation unit. The irradiation unit irradiates sensing light in a detection target direction. The photodetectors is arranged in a matrix and responds to the sensing light. The level adjustment unit changes an irradiation intensity of the sensing light or detection sensitivity of the photodetectors. The peak detection unit detects a received light pulse and a peak of the received light pulse. The pulse information acquisition unit acquires, as pulse information, a data set indicating a predetermined feature amount related to the received light pulse. The pulse information includes normal and suppression pulse information. The distance calculation unit calculates a distance value to the target based on the normal and suppression pulse information.
