In combination with the measurement technology of the stereo machine vision and the measurement principle of CCD, a new method to measure the sighting line parameters of the helmet-mounted sight is presented, the possible error source is analyzed, and the solution is proposed. Based on the mathematical model of bore-sighting measurement for helmet-mounted sight, the characteristic points on the helmet were constructed by means of machine vision to acquire the characteristic point coordinate, and then resolve the parameters of the boresighting. The structure of the system is simple. The measuring accuracy can satisfy the accuracy requirement of resolving the bore-sighting parameters for the helmet-mounted sight.
