Title: DISTANCE MEASUREMENT DEVICE, CONTROL METHOD FOR DISTANCE MEASUREMENT, AND CONTROL PROGRAM FOR DISTANCE MEASUREMENT
Abstract:
This distance measurement device emits a directional light on a subject, measures the distance from the subject by receiving reflected light of the directional light, and determines the correspondence relationship between an irradiation location in a temporary image, said location corresponding to the location of irradiation of the subject by the directional light in a temporary image obtained by temporarily imaging the subject each time one of a plurality of distances is temporarily measured, and a distance temporarily measured using the directional light corresponding to the irradiation location in the temporary image, and, on the basis of the determined correspondence relationship, derives an irradiation location in a main image, said location corresponding to the location irradiated by the directional light used during a main measurement in a main image obtained by means of a main imaging, and, if the distance obtained by means of the main measurement is outside the range of distances specified by means of the correspondence relationship, performs predetermined processing as processing that contributes to suppressing a deterioration in the accuracy of the irradiation location in the main image.
