چکیده انگلیسی
Aiming at the shortcomings of calibrating the screen plane equation by using traditional double theodolite intersection method, the optimization program of accurately calibrating the screen plane equation of the sky screen vertical target is proposed. The LED surface light source without off-axis phenomenon is designed as projection light source of light screen. The position and attitude of the reference ruler of the double theodolite measurement system are optimized. The technology of thickness center recognition of light screen are studied, which is designed a special light screen receiver with the functions of translation, rotation, lifting, fine adjustment, image capture and processing. The accurate calibration experiment of the screen plane equation of the sky screen vertical target has been completed. The feasibility and rationality of this scheme are verified through live fire experiments. Compared with the traditional double theodolite calibration method, the coordinate accuracy of the optimized calibration method is improved from 4 mm to 3 mm in an effective target surface of 1 m × 1 m.
