Abstract:
A distance measuring apparatus measures a distance to a target from a plurality of directions, and includes sensors having identical two-dimensional scan type configurations that launch a laser beam and receive reflected light from the target by a multi-segment light receiving element, and a processor. The processor performs a process including specifying a receiving part of the multi-segment light receiving element of a first sensor, that receives a second laser beam launched from a second sensor in a state in which the target is non-detectable by the first sensor, adjusting a phase in a vertical scan direction of the second laser beam with respect to that of a first laser beam launched from the first sensor, until the receiving part no longer receives the second laser beam, and integrating range images from the first and second sensors after the phase is adjusted.
