Embodiment Construction
[0037] The working principle and process of the seamless mosaic method of large-format equivalent central projection images are as follows: figure 1, including: a. Rotating image acquisition based on rotating camera; b. Rotating image projection transformation; c. Precise relative orientation of rotating image taking into account camera pose offset; d. Seamless splicing of large-format equivalent central projection images; e. Stitching accuracy assessment. Aim at the application requirements of precision close-range photogrammetry, organically combine precision engineering measurement with photogrammetry, design a method of mounting a camera on a two-dimensional rotating platform to form a rotating camera, and cooperate with computer applications to form a large-format equivalent central projection image acquisition integrated system .
[0038] Such as figure 2 The rotating camera system includes three parts: rotating platform 4, camera 6, camera control and image processin...
