[0016] In order to better understand the present invention, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0017] figure 1 Schematic diagram of the measurement method of spatial circle geometric parameters based on monocular vision technology, figure 1 An arbitrarily configured monocular vision system is given in. OXYZ is the camera coordinate system, O w X w Y w Z w Is the world coordinate system, where O w At the center of the space circle, X w -Y w The plane is the plane where the space circle lies. Suppose the rotation matrix and translation vector between the world coordinate system and the camera coordinate system are R and t respectively, and mark R=[r 1 r 2 r 3 ], where the three-dimensional column vector ri represents the i-th column of the matrix R, i=1, 2, 3.
[0018] In the above coordinate system configuration, the vector t represents the position of the center of the s...
