Laser positioning method and system for nuclear reactor voltage stabilizer video inspection device

The invention provides a laser positioning method and system for a nuclear reactor voltage stabilizer video inspection device. The laser positioning method comprises the steps that S1, a laser markingdevice is installed at the tail end of a supporting frame of the video inspection device, and reference laser rays are projected to the inner surface of a cylinder body of a voltage stabilizer through the laser marking device; S2, a camera is used for acquiring image information of the reference laser rays, and the deflection angle between the direction of the camera and the reference laser raysis calculated; S3, positioning of the video inspection device is corrected according to the deflection angle. The laser positioning system comprises the laser marking device used for projecting the reference laser rays and a processing center used for calculating the deflection angle. According to the laser positioning method and system for the nuclear reactor voltage stabilizer video inspection device, machine vision posi
