Method of miss distance measurement for projectiles in the suppression
摘要
Abstract
Aiming to the problem of miss distance measurement in the suppression,which generates by the restriction of topographies and movements in the traditional burst points test system,a set of pointing system in air is established,and it is installed on an unmanned plane.By utilizing the external calibration,the internal parameters of the image pickup system are corrected.And then by correction of image plane and target position extraction,the ground points of the projectiles are obtained exactly. The experiment result shows that the imaging size of camera is 727.9 m×352.7 m,which meets the test requirement within 100 m in horizontal and 300 m in vertical.In addition,the precision of camera is 0.1 m when the pixel number is 4 096×2 048,which meets the requirement that the test precision is less than 0.3 m.The proposed method has the theoretical value and the practical significance.关键词
