The invention discloses a method for accurately measuring the distance of a target object in a pan-tilt rotation process, a laser range finder is arranged on a pan-tilt camera, and the optical axis of the laser range finder is parallel to the optical axis of a camera of the pan-tilt camera. According to the method for accurately measuring the distance of the target object in the pan-tilt rotation process, the target object is identified in the process of detecting and scanning the target object through the pan-tilt camera, then the target object in the area is subjected to target object distance measurement and scanning, and the angle of the pan-tilt camera is adjusted; the angle of the pan-tilt camera is aligned with each target object in the area, so that the light beam of the laser range finder can just irradiate on the target object, accurate range finding is carried out on the target object, and the problems that in the prior art, the range finding result is inaccurate or the scanning process is frequent
