Abstract

The invention relates to a high-precision positioning method, device and system, an electronic device and a storage medium, and the method comprises the steps: obtaining the shore bridge position information of each shore bridge in a port in real time based on a V2X networking technology; processing the position information of each quay crane and the quay crane point cloud template to generate a quay crane point cloud map; taking currently acquired laser radar data as a to-be-matched point cloud, taking a quay crane point cloud map as a reference map, taking current position information of a container truck as an initial position of the to-be-matched point cloud, and utilizing a point cloud registration algorithm to obtain an optimal matching position of the to-be-registered point cloud in the reference map; obtaining the pose change information of the to-be-registered point cloud relative to the initial position; according to the pose change information and the initial pose of the container truck, obtaining current container truck position information; and filtering according to the current container truck position information in combination with the obtained mileage data and inertia measurement data to obtain the positioning information of the current container truck. According to the invention, reliable and high-precision positioning is realized in the quay crane area.

Description

technical field [0001] The present application relates to the field of positioning of unmanned truck collection, in particular to a high-precision positioning method, device, system, electronic device and storage medium. Background technique [0002] With the rapid development of the international logistics industry, the number and throughput of container ports around the world continue to rise, and the operation intensity in the port is also increasing and becoming saturated. It is becoming more and more difficult to meet the current demand for operational efficiency and strength, and unmanned collection trucks in ports emerged as the times require. In the process of driving unmanned collection trucks in ports, how to realize the stable and reliable self-positioning of unmanned collection trucks is the basis and key to the application of various other unmanned driving functions or terminal operation functions. The container terminal environment is different from the common...
