The invention discloses a method and device for performing X-ray transillumination using a GIS cylinder as a support. The method in the invention is a method of installing a mechanical lifting device on the GIS cylinder to perform X-ray transillumination. The device includes a GIS cylinder (10), the two sides facing the top of the GIS cylinder (10) are provided with hoisting pulleys (5), and there are hoisting ropes (3) on the hoisting pulleys (5), and the two ends of the hoisting ropes (3) Pass through the hoisting pulley (5) and connect with the hand winch (2) located under the GIS cylinder (10), and install the DR plate assembly hanging frame (4) on the hoisting rope located on one side of the GIS cylinder (10), An X-ray machine hanging mechanism (8) is provided on the hoisting rope (3) on the other side of the GIS cylinder (10). The invention can effectively solve the problems in the prior art that the lifting and fixing method of the X-ray machine and the DR board is not practical, the transillumination is inconvenient, the occupied space is large, and the on-site space is difficult to meet the requirements in the X-ray detection of the GIS equipment in the prior art.

The invention belongs to the technical field of logistics, and discloses a visual and active interaction-based detection and correction method for a packing box segmentation error. Carrying out regionextraction based on a target detection model result; performing Suspected error segmentation detection based on a two-dimensional visual algorithm; performing Error segmentation judgment based on anactive interactive strategy; Correcting error segmentation and calculating a correct grabbing position; based on Two-dimensional vision-based algorithm, the possible problems of under-segmentation andover-segmentation of the prediction result of the target detection model are pre-judged; a gripper of the robot to perform trial gripping is guided on the target, the size and position change of thebox body are tracked, detecting whether the comparison result is matched with a prior segmentation result or not, if yes, continuing to complete gripping on the target, and if not, performing correction on error segmentation. The visual-based interactive strategy can effectively correct the packaging box which is wrongly segmented, the risk that the packaging box is broken down is avoided, and therobustness of the robot for accurately grabbing the packaging box is greatly improved.
