Abstract
A distance-measuring apparatus, a mobile object, a distance-measuring method, and a distance-measuring system. The distance-measuring apparatus and the distance-measuring method include performing matching for a plurality of images obtained by a plurality of imaging devices to convert the plurality of images into first distance information on a pixel-by-pixel basis, emitting a laser beam where at least one of a laser-beam resolution in a horizontal direction and a laser-beam resolution in a vertical direction exceeds two degrees, obtaining a reflected signal obtained when the laser beam is reflected by an object, detecting a peak that corresponds to reflection from the object from the reflected signal, calculating second distance information based on a length of time taken to observe the peak after the laser beam is emitted in the emitting, and integrating the first distance information and the second distance information with each other. The mobile object includes the distance-measuring apparatus.
