| 3. | If the location of calibration block is changed , and several computation is processed toward different coordinates every time , the internal parameters such as uo , vo , f , d will not change . through lots of times calibration , the result is averaged , the precise result will be obtained . after the pretreatment , an image easy to recognize and understand for computer is produced 这样变动标定块在世界坐标的位置,在进行几次标定计算,每次虽然相对于不同的世界坐标系,但对于不变的同一个系统,内部参数u 、 v 、 f ,摄像机之间的距离d ,都不会变化,这样通过多次标定后,将结果进行加权求平均,可得到精确的结果。 |
