The invention discloses an obstacle distance measuring method and device, a vehicle and a medium. The method comprises the steps that when it is determined that an obstacle exists in the vehicle driving direction according to a captured first driving image, obstacle area information of the obstacle is determined, and a light beam emission mode is determined in combination with the current vehicle speed; controlling left and right radio frequency mechanisms on the vehicle to emit light beams in a light beam emitting mode; light spot focusing parameters of the light beam spots are adjusted in a light spot focusing mode matched with the light beam emission mode, and a second driving image containing the adjusted light beam spots is obtained; and determining the spacing distance between the vehicle and the obstacle according to the second driving image. According to the method, light beams are emitted in a light beam emitting mode and a light spot focusing mode matched with obstacle area information and vehicle speed, images containing light beam spots are analyzed, and the spacing distance is determined. Intelligent tracking and accurate distance measurement of obstacles are realized based on visual perception, and compared with a radar distance measurement method, the hardware architecture cost is reduced.
