Embodiment Construction

[0035] The present invention will be further described below through specific embodiments.

[0036] see figure 1 , a smart truck positioning method that combines AI and vision. The camera is pre-installed to shoot the video of the lane. Because the distance and angle between each lane and the camera are different, there is a certain slight deformation from the video. Calibration is required to correct this distortion.

[0037] In the present invention, the data calibrated by the camera includes the parking point of the vehicle, and the coordinates of the spreader, the pixel points occupied by the container on the lane, etc. can also be calibrated as required. The calibrated vehicle parking point, that is, the coordinates of the center point of the container in the picture taken when the vehicle is parked at the exact position of the lane. In the present invention, several lanes may be included, and the lanes are numbered and vehicle parking spots are marked respectively.

Abstract

An AI and vision combined intelligent container truck positioning method and device calibrate a vehicle parking point through a camera in advance, and the AI and vision combined intelligent containertruck positioning method comprises the following steps: 1) reading a video stream of the camera, decoding the video stream into a picture, and preprocessing the picture; 2) inputting the processed picture into a pre-trained Mask RCNN neural network for deep learning for positioning to obtain a central point of the container or the frame, calculating an Euclidean distance between the central pointand a calibrated vehicle parking point, if the Euclidean distance is greater than a preset value, returning to the step 1), and otherwise, entering a step 3); and 3) matching the picture with a template of the container or the frame by adopting a template matching algorithm, and outputting an optimal solution to obtain the position of the container or the frame.

Description

technical field [0001] The invention relates to the field of truck positioning, in particular to an intelligent truck positioning method and system combining AI and vision. Background technique [0002] Containers are an important logistics tool for port transportation, loading and unloading. At present, when the port is carrying out container loading and unloading operations, the driver of the gantry crane uses the operating handle to manually control the spreader to align and grab the container. During the operation, the driver needs to be highly focused, and long-term work will cause driver fatigue, which will reduce the efficiency and accuracy of alignment operations. [0003] In addition, during the loading and unloading process of the cargo ship, the bridge crane does not move in a fixed position. After the previous container truck is loaded and unloaded, the next container needs to be driven to the designated position, so the container truck is generally in place ah...
