。 an imaging unit mounted on a moving body that converts external world images into electrical signals; a plurality of image position detection units that detect multiple target target positions from imaging unit signals of the imaging unit;
Based on the speed detection unit that detects the motion speed of the moving object, the image positions of the plurality of targets obtained by the image position detection unit, and the speed obtained by the speed detection unit, the distance is calculated as 1NN〓 i = 1 V・T/△θi (where N is the number of targets, V is the speed of the moving object, T is the measurement interval,
△θi is the position change of the target detected for each object. Passive distance measuring device.
