一种基于空间方位角的投影瞄准算法
A projection aiming algorithm based on spatial azimuth
摘要
Abstract
In order to solve the problem of the deviation between the actual aiming position in the real environment and the virtual aiming position in the projection scene in virtual aiming training system,a projection aiming algorithm based on spa-tial azimuth is proposed.The projection plane space is located and the space rectangular coordinate system is established ac-cording to the spatial azimuth information collected by electronic compass.The coordinate difference caused by the screen projection distortion is eliminated through converting the space rectangular coordinate to pixel coordinate.The deviation problem caused by the rotation of the pivot point is solved by analyzing the motion trajectory.Experimental results show that according to the algorithm,the actual aiming position is unified,and the position deviation caused by the projection dis-tortion and the pivot rotation is reduced effectively.The training effect is guaranteed.关键词
