The invention discloses a variable-diameter steel pipe inner wall full-coverage automatic detection method, which comprises the following steps: adjusting each camera on a camera module to an initial site after a pipe climbing device enters a pipe, shooting the inner wall of a variable-diameter steel pipe by the camera module in the process that the pipe climbing device moves back and forth along the pipe, and adjusting each camera site of the camera module in the shooting process, and 360-degree shooting of the inner wall of the reducing steel pipe is completed. According to the invention, the detection requirements of different pipe diameters in the large-pipe-diameter steel pipe can be met, the detection precision and the detection speed can be ensured while the stability is ensured, and the 360-degree full-coverage full-automatic detection requirements of the inner wall of the pipe are met.

The application provides an image overlap rate detection method, device, equipment and computer storage medium. When calculating the overlap boundary position by the image overlap rate detection method, only the boundary sub-image and each reference sub-image in the reference image need to be compared and calculated, the number of pixel points involved in the calculation process is less than that of directly comparing and calculating the target image and the reference image, so the detection speed is faster. Moreover, since all the pixel points in the target image are not involved in the calculation process, the possibility of misidentification is reduced, so the detection accuracy of the image overlap rate is higher for images containing a large amount of repeated image information, such as warehouses. It can be seen that the image overlap rate detection method provided in the application can ensure the detection accuracy and speed of the image overlap rate at the same time.
