Abstract
In a three-dimensional measurement apparatus, a plurality of cameras and an arithmetic device are connected via a network, and includes: a plurality of photographing units; an image acquisition unit; a local time acquisition unit; a moving object detection unit to detect a moving object from the image; an image holding unit to hold an image in which the moving object is detected, in association with the local time at which the image has been photographed; an image selection unit; a three-dimensional position/synchronization deviation estimation unit to estimate a three-dimensional position of the moving object and a synchronization deviation between cameras, from an image selected by the image selection unit and a local time associated with the image; a synchronization deviation holding unit to hold the synchronization deviation; and an output unit to output an estimation result of the three-dimensional position/synchronization deviation estimation unit.
