First Claim
Patent Images

1. object measuring method, first image capturing device that utilizes one group of non-parallel setting and second image capturing device and the processing module that is connected with this first and second image capturing device are measured object, and this method may further comprise the steps:

  • (1) make this first image capturing device and this second image capturing device capture first image and second image of the check point of at least one known spatial coordinate respectively;

    (2) make this processing module with in this first image and this second image to the parameter substitution of check point that should known spatial coordinate geometric function based on light beam intersection collinear image formation principle, twist parameter, second optical center and second attitude parameter with second camera lens that utilizes default algorithm to calculate this geometric function and then to solve the distortion of first camera lens parameter, first optical center and first attitude parameter and this second image capturing device of this first image capturing device;

    And(3) make this processing module with this first camera lens distortion parameter of being solved, this first optical center, this first attitude parameter, this second camera lens distortion parameter, this second optical center and this second attitude parameter substitution should geometric function based on light beam intersection collinear image formation principle in, with generation to the first light beam intersection conllinear function and the second light beam intersection conllinear function that should first and second image capturing device.
