The method of solving the non-coplanar perspective-four-point (P4P) problem

Along with the development of the technique of in the large off-axis missile,the helmet mounted display system(HMDS) play the more and more important function in the airplane battle.Currently, the computer vision measurement is popular technology using to calculate line of sight(LOS) In HMDS. We deduce the solution of the non-coplanar perspective-four-point(P4P) problem based on PNP problem in computer vision measurement and the coplanar P4P linear algorithm. Then we get the solutions which are symmetry concerning with imaging plan by imitation.The solution can be obtained and we use matlab tool to simulate and validate. Our method has much meaning of reality using in HMDS.
