文摘This paper describes a method for estimating intrinsic and extrinsic parameters of a camera,including horizonal scale factor caused by imperfect match between computer image acquisition hardware and camera hardware,coordinates of image center(c x ,c y) and lense radical distortion parameter k,which calculates extrinsic parameters by a tetrahedra pose estimation algorithm and then get all other parameters by nonlinear optimization in two steps,and simulations show this method is easy and reliable.
