To improve the operating efficiency of high power laser facility project, a simulation system using “OpenGL”graphics software is built to evaluate the target positioning algorithm at the debugging phases, which is independent on unperfect hardware experimental environment. The proposed positioning method calculates the target's spatial coordinate and rotational angles by integrating the feature values abtained by three CCDs， and adjusts the target-sending mechanism to put the target in a desired position. The simulation results show the target-sending mechanism is confirmed to be able to adjust the target in a desired position based on the measurement results, which verifies the practicality of the proposed positioning algorithm to be used in the real ICF physical experiment.
