Abstract: The present disclosure provides a grinding robot for an inside wall of a small diameter pipe. The grinding robot includes a grinding device, a transmission device, and a driving device. By arranging the grinding robot into the above three portions, the overall bending pipe passability of the robot can be increased, which is convenient for the grinding robot to grind the small diameter pipe. A first gimbal and two second gimbals provided in the transmission device enable the grinding robot to flexibly pass through bends of the pipe, and enable a grinding driving force to be variably transmitted to the grinding device. When the grinding body rotates and contacts a pipe wall, a reaction force of the pipe wall on the grinding body is balanced by an adjusting spring adjustment force in a balance adjusting device and a self-weight of a grinding body.

Abstract: A method of enhancing an abnormal area of a ground-penetrating radar image based on hybrid-supervised learning includes the steps of: building a database including a real image set, a simulation image set and a simulation image label set; adopting a generative adversarial network; processing semi-supervised training and unsupervised training alternately to obtain a trained model, then inputting a real radar image with abnormal area that needs to be enhanced into the model and processing through the generative network to output an abnormal-area-enhanced image. The method overcomes the problems of differences in characteristics between simulated images and real images, and low utilization efficiency of real image information by unsupervised methods, and improves the utilization efficiency of the enhanced network for real image information, the saliency of abnormal areas on real images, and the generalization ability of the enhanced network, therefore effectively enhances the significance of abnormal areas in ground-penetrating radar images.
