Ship gun laser correction device

The utility model relates to the technical field of optical equipment, in particular to a ship gun laser correction device which comprises a collimation system, a positioning shaft, a display terminal and a laser receiving target, one end of the positioning shaft is inserted into a ship gun barrel, the other end of the positioning shaft is connected with the collimation system, and the laser receiving target is placed in a visible area of the collimation system. An expansion hand wheel is arranged on the side, close to the collimation system, of the positioning shaft, so that the center axis of the positioning shaft can be consistent with the center axis of the ship gun barrel after the positioning shaft is inserted into the ship gun barrel, a collimation objective lens, a laser collimation lens, an image sensor and a laser are arranged in the collimation system, and the center axis of the collimation objective lens is consistent with the center axis of the image sensor. The central axis of the laser collimat
