Paper Abstract

Aimed projective distortion caused by tilted camera in traditional photogrammetry, a projective distortion self-corrected photogrammetry is proposed used to measure the projectile coordinates. The causes of projective distortion and the impact on the measurement accuracy are analyzed. Through the analysis of the imaging model of random points on the target, The formula to solve the object distance is deduced. The correspondence between the coordinates on the image and the coordinate on the target of the projectiles is established. According to Extraction and calculation of 4 markers sited on the target, the constant in the correspondence is solved. The measurement error caused by projective distortion is overcome. The absolute measurement of projectile coordinate on the target is realized. The test result shows that the projectile coordinate on the target can be accurately measured using the method designed in this paper. The accuracy and consistency of fire intensity measuring is increased. It also can be used to check the other related automatic measuring equipments.
