DISTANCE MEASURING DEVICE

摘要

The purpose of the present invention is to provide a distance measuring device that dynamically detects interference from an unknown time-of-flight (TOF) distance measuring system. Provided is a distance measuring device (10) wherein a control unit (4), in a prescribed period, generates a first exposure signal through third exposure signal and regenerates a specific exposure signal which is one from among the first exposure signal through third exposure signal. A light receiving unit (2), in a prescribed period, carries out a first exposure processing through third exposure processing, and once again carries out a specific exposure processing which corresponds to a specific exposure signal from among the first exposure processing through third exposure processing. A calculation unit (3) determines whether light emission from another distance measuring device and light emission from this distance measuring device interfere with each other, such determination being made on the basis of the difference between an exposure amount obtained by a first instance of specific exposure processing and an exposure amount obtained by a second instance of specific exposure processing that are carried out during a prescribed period.
