空间三维测量技术的研究

The Study on Spatial 3-D Coordinate Measurement Technology

以透视投影变换为依据,研究了空间三维测量技术,提出了一种新的标定方法。利用相机做一次平移运动,可以线性的确定摄像机的内参数,然后利用已求得的内参数来求外部参数。本方法不需精确标定靶标,不需要任何的高精度复杂装置,最后结果表明,此方法能够得到比较满意的精度要求。

In terms of perspective projection transformation this paper study the technology of spatial 3 - D coordinate. New camera calibration technique is proposed. By controlling the camera to translate along one direction, the camera intrinsic parameters can be solved linearly. According to the known intrinsic parameters, we can get the extrinsic parameters. There isn＇ t necessary any accurate calibration target and complex equipment. The experimental results show that satisfactory calibration precision be get by using this method.
