Approaching the coordinates of 3D objects alternately from multiple orthogonal views
应用多个正交视角轮流逼近3维目标的坐标

To achieve accurate 3D positioning and real-time tracking of moving objects,a video positioning method using multiple orthogonal cameras together with an iterative algorithm that approaches the coordinates of the 3D objects alternately is proposed.The optical axes of the cameras are set along axes of an orthogonal coordinate and all cameras are pointed to the origin of coordinate.Unlike the most of current computer vision method,the iterative algorithm does not involve image alignment operation,which could affect the positioning efficiency and precision.The convergence of the iterative algorithm is proved.Numerical examples and practical tests show that the proposed method is simple to compute,insensitive to errors,and has a rapid rate of convergence,thus has a great potential in application.
