The target positioning precision of multi-beam laser facility is crucial to future inertial confinement fusion experiments, so the calculation methods have been developed for estimating the target positioning precision. The measurement method of target positioning precision based on the X-ray pinhole camera was presented. The coordinates of target center position determined by microscope and read by X-ray pinhole camera after the shoot on CH target of multi-hole, the conversion relationship of coordinates between target plane and X-ray pinhole camera was established. The template of focal area was acquired after the shoot of focal area target. The match method of template was adopted, and the position coordinates of focal area center were obtained by X-ray pinhole camera. The position of focal area center in the target plane coordinates can be calculated through the conversion of coordinates, and then the target positioning precision measurement of the laser system can be calculated. The measurement technology and methods of target positioning precision of multi-beam laser facility are presented, and the uncertainty is analyzed, consequently.
