摘要
根据摄像机透视投影模型的几何意义,从几何角度推导了由投影矩阵求解摄像机内外参数的过程以及任意矩阵能够成为透视投影变换描述的约束条件。
According to the geometric meaning of perspective projection camera model,the process of solving camera intrinsic and extrinsic parameters has been deduced by using geometric technique.For any given matrix,the constraint conditions have been discussed when the matrix can be described as a perspective projection transformation.
