  • In order to improve the measuring accuracy of single-linear array CCD camera and dual-laser vertical target system, theoretical and experimental basis is provided for the system design. Theoretical analysis is carried out on the measuring error and the system measuring error formula is derived based on the establishment of system's mathematic model. Measurement error is simulated by Matlab software. The influence of error factors on measurement error of target coordinates is obtained, and error distribution in 1 m×1 m target surface is obtained. Error analysis is carried out by simulating the live ammunition experiment. Experimental results show that standard deviation σx and σy for measuring error of the x-coordinate and y-coorcinate are 4.1 mm and 10.2 mm respectively, and the error of the simulated live ammunition coordinate is consistent with the theoretical analysis.
