【Abstract】 Theory of intersectant measurement for linear CCD array camera is studied in this paper.The precision of missile and cannonball are obtained in real time by practical target replacing a dummy target.Analyzing the precision factor of intersectant measurement,then the coordinate measuring precisions of various positions in photoelectric target are calculated.The relation between the measuring precision and the position of the linear CCD array camera has been obtained.The conclusion is the measuring system has highest measuring precision under the condition of the angle of two linear CCD array camer’s sight axis is 90°.更多还原
