The application discloses a method, device and storage medium for calibrating the relative posture of a camera and a rotation axis, specifically, the first camera collects sampling images at each sampling position, wherein the sampling position is the rotation axis driving the second camera to rotate a preset angle After the stop position, the sampling image includes the whole first calibration plate; each first corner point is extracted on each sampling image, and the fitting plane of each first corner point is generated; each first corner point is placed in each sampling The coordinates of the first corner point on the position are respectively projected on the corresponding fitting plane to generate the fitting circle of each first corner point; according to the fitting circle, the first attitude calibration parameters of the second camera and the rotation axis are calculated, and The relative attitude of the second camera and the rotation axis is adjusted according to the first attitude calibration parameter. In the embodiment of the present application, by setting the first camera to assist in the calibration of the second camera and the rotation axis, and calculating the first attitude calibration parameters of the second camera and the rotation axis, accurate calibration between the rotation axis and the camera is realized.
Description
technical field [0001] The present application relates to the field of computer vision, and in particular to a method, device and storage medium for calibrating the relative posture of a camera and a rotation axis. Background technique [0002] In the process of image measurement and its visual application, in order to determine the relationship between the three-dimensional geometric position of a point on the surface of a space object and its corresponding point in the image, it is necessary to establish a geometric model of camera imaging, and these geometric model parameters are camera parameters. Under most conditions, these parameters must be obtained through experiments and calculations. This process of solving the parameters is called calibration of the rotation axis of the fixed camera (or camera calibration). Whether it is in image measurement or machine vision applications, the calibration of camera parameters is a very critical link. The accuracy of the calibrati...
