The invention discloses a three-dimensional POI matching method based on remote sensing and digital twinning and a storage medium, and the method comprises the steps: building a twinning model sample library according to three-dimensional point-of-interest models in a digital twinning scene, and setting labels for the three-dimensional point-of-interest models, the labels including categories, colors and shapes; performing target identification in the remote sensing image to obtain a target object area and a label of a target object; according to the label of the target object, performing retrieval matching in the twin model sample library to obtain a three-dimensional interest point model corresponding to the target object; and placing the three-dimensional interest point model corresponding to the target object in the target object area. According to the invention, automatic matching and placement of the three-dimensional interest point model of the remote sensing image and the digital twinborn scene can be realized.

This application provides an automatic traffic cone placement device, including an engineering vehicle, a placement mechanism, a traffic cone compartment, and a conveying assembly. The placement mechanism includes a base, a connecting rod, and a clamping assembly. The clamping assembly clamps the traffic cones in the traffic cone compartment vertically with the cones facing downwards, and flips them away from the base via the connecting rod, so that the traffic cones are placed on the road surface vertically with the cones facing upwards. During the clamping process, the center of gravity of the traffic cones is close to the clamping assembly, resulting in high clamping stability. The placement of the traffic cones is completed by a set of rotating joints on the connecting rod and the base, eliminating the need for multiple rotating joints for precise coordination. This device has the advantages of low precision requirements, high clamping stability, low implementation cost, convenient operation, and ease of promotion and implementation.

This utility model discloses a wireless charging mechanism and charging parking space for automobiles, relating to the field of charging equipment technology. It includes a lifting mechanism, a frame, a charging module, a sliding rod assembly, and two drive mechanisms. The lifting mechanism drives the frame to move up and down. In use, when a vehicle is parked in the parking space, the lifting mechanism drives the frame to move up and down, adjusting the height of the charging module to match the vehicle's battery height. When the vehicle's parking position is inaccurate or the battery positions differ between vehicles, the two drive mechanisms drive the first and second sliding rods to slide. Since the first and second sliding rods are perpendicular to each other, the horizontal position of the charging module can be adjusted to ensure it matches the vehicle's battery position for charging. This design has lower requirements for the accuracy of the vehicle's parking position and is adaptable to charging different vehicle models.
