This utility model provides a multi-station tool storage device for electrical maintenance of equipment, relating to the technical field of tool storage equipment. It includes a storage rack assembly, which is composed of a main board body and further includes a sliding limit frame on the main board body. Gear plates are provided on the opposite sides of the main board body. An adjusting slide rod assembly plays a core adjusting and supporting role during device operation. The slide rod slides along the sliding limit frame, flexibly adjusting the overall component position to adapt to different tool storage needs. A concave frame on one side provides stable support for the rod, facilitating the installation and use of hook components. Press-fit fixing sleeves at both ends of the slide rod engage with the gear plates through press-fit grooves, firmly fixing the slide rod in the target position and preventing component displacement during tool storage. This structure ensures the stability of tool storage and improves the adaptability of the device to different tool storage scenarios, facilitating the orderly conduct of multi-station maintenance work.

This invention proposes a registration method for point clouds with low overlap rates, effectively improving upon traditional point cloud registration methods which suffer from slow speed, low accuracy, and poor stability. The method is based on variable data sequence length least truncated squares (LTS). For the complete sequence obtained by ascending ordering the Euclidean distances of matching point pairs, since pose changes after each iteration cause variations in the distance sequence of the matching point pairs, in each iteration, using the right endpoint of the complete sequence as a reference, a dynamically changing local sequence is selected from the complete sequence based on the point cloud overlap rate and the current iteration number. This changes the position of the LTS truncated sequence on the complete sequence. When the iteration termination condition is met, the maximum length of the local sequence is the same as the length of the complete sequence. As the iteration progresses, the length of the local sequence continuously increases, thus implementing a variable data sequence length strategy during registration. Compared with traditional point cloud registration methods, this invention offers better speed, accuracy, and stability, especially when registering point clouds with low overlap rates, where the performance improvement is particularly significant.
