摘要

A distance measuring apparatus for measuring a distance to a distance measurement object based on a time from projection of an irradiating light onto the distance measurement object until reception of a reflected light from the distance measurement object, the distance measuring apparatus including a light projecting unit configured to project the irradiating light onto the distance measurement object; a light receiving unit configured to receive the reflected light; and a distance measuring unit configured to measure the distance to the distance measurement object based on a time from projection of the light the irradiating light onto the distance measurement object by the projecting unit projects until reception of the reflected light by the light receiving unit. The distance measuring unit calculates an integrated waveform based on a reference waveform of a reference signal related to the projection of the irradiating light and a waveform of the received light signal based on the received reflected light, determines, based on the integrated waveform, the time from the projection of the irradiating light onto the distance measurement object by the light projecting unit until the reception of the reflected light by the light receiving unit, and calculates the distance to the distance measurement object based on the determined time until reception of the reflected light.
