Research of gun muzzle offset measuring method

A suit of the measuring system which using endospore locating mode to measure the gun muzzle offset was proposed in this article. It also analysed varied sources of errors, estimated the system´s measuring accuracy as well, and in the meantime it discussed the test method of the measuring accuracy which had been tested through experiments, at last, some type of the artillery gun muzzle offset was measured by this measuring system. Less environment light interference, clamping faster, more accurately, and high repeat positioning accuracy made this method feasible and useful.
