| description | The invention belongs to the detection technology, and provides a free binocular stereoscopic vision parameter calibration method, which is convenient for operation and is relatively simple in calibration process, for a rotating shaft. The method enlarges the view field of a camera, and the coordinates of a plurality of position origins are obtained in a process that the camera rotates around the rotating shaft, and then the parameters of the rotating shaft are accurately calculated. According to the invention, the method comprises the following steps: 1, calculating the spatial coordinates of the origin of a camera coordinate system in the world coordinate system; 2, calculating the world coordinates of the origins of camera coordinate systems at a plurality of positions; 3, repeatedly carrying out the steps 1 and 2, and obtaining the coordinates of the origins of the positions of more cameras; 4, calculating a plane where an arc track is located according to the spatial coordinates of the origins of the cam |
