Embodiment Construction
[0069] The present invention will be described in more detail below through specific embodiments in conjunction with the accompanying drawings.
[0070] The following embodiment provides a camera calibration method, generally speaking, the method includes the following aspects: a calibration template encoding method, used for identification of calibration templates during three-dimensional reconstruction of large, medium and small objects; The calibration template layout and image acquisition method are used to arrange the calibration template in the scene containing the three-dimensional object to be reconstructed and obtain a series of images; the image processing method processes the acquired images to obtain all visible calibration templates in the image The calibration point outline; the calibration point recognition method is used to identify and distinguish template calibration points and template calibration point groups from the contour set; the template recognition me...
