The invention relates to a laser ranging calibration method, system and device, computer equipment and a storage medium. A calibration module acquires a ranging value measured by a laser range finder,and the ranging value is a distance value measured by the laser range finder after a laser is transmitted to a receiving end of the laser range finder from a transmitting end of the laser range finder through an optical fiber path; then, the ranging value is compared with a preset equivalent distance value, and a comparison result is obtained; and the laser range finder is calibrated according tothe comparison result. By adopting the method, calibration of the laser range finder can be completed in a very small space, a requirement on the calibration space is reduced, automation of a calibration process is favorably realized, and production cost is reduced; furthermore, the calibration work can be carried out in a standard environment and is not influenced by a humidity environment.
Description
technical field [0001] The present application relates to the technical field of laser ranging, in particular to a calibration method, system, device, equipment and storage medium for laser ranging. Background technique [0002] Laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. It has the advantages of fast ranging, small size, and reliable performance. It has been widely used in industrial distance measurement and topographic measurement. When producing laser ranging devices, it is very important to calibrate the ranging accuracy. [0003] When calibrating the laser rangefinder in the traditional technology, a reflector is placed in a wide field, and the distance between the laser rangefinder and the reflector is tested by other standard measuring tools as the calibration value of the laser. [0004] However, using the above method for calibration requires relatively high space requirements for the test site, resulting in ...
