Container truck guiding and positioning system and method, computer storage medium and gantry crane

Abstract

The invention discloses a container truck guiding and positioning system and method, a computer storage medium and a gantry crane. The system comprises a calibration module which carries out the calibration of a parking point of a container truck in advance; the acquisition module is used for acquiring the video stream of the calibration module, decoding the video stream into a picture and preprocessing the picture; the AI vision algorithm module is used for inputting the preprocessed picture into a PANet neural network algorithm model to obtain an instance segmentation map of a container or a frame of the container truck, and then carrying out binarization edge detection and minimum area bounding rectangle operation to obtain a central point coordinate of the container or the frame and an included angle between the central point coordinate and the horizontal direction; the judgment module is used for obtaining the parking point of the calibration container truck of the calibration module, the center point coordinate of the container or the frame of the AI vision algorithm module and the included angle between the center point coordinate and the horizontal direction, and calculating the distance between the parking point of the calibration container truck and the center point of the container or the frame; and the data recording module is used for recording historical records of each module. According to the invention, real-time detection, recognition and positioning tracking of the container truck are realized.

Description

technical field [0001] The present invention relates to a collection truck guidance and positioning technology, and more specifically, to a collection truck guidance and positioning system and method, a computer storage medium, and a gantry crane. Background technique [0002] Container trucks (hereinafter referred to as trucks) are an important logistics tool for container transportation, loading and unloading in ports. The truck guidance and positioning system is mainly used to guide the truck driver to dock to the correct position quickly and accurately under the crane to improve the operating efficiency of the crane. [0003] Usually, before the container is loaded and unloaded, the container truck needs to enter the designated area according to the established lane, and the lifting equipment such as the gantry crane at the port is driven to the top of the container truck, and the spreader is lowered to load and unload the container. In this process, whether the containe...

Problems solved by technology

The disadvantage of this solution is that the efficiency of the former is low, which affects the overall efficiency of the port; the latter requires laser scanning equipment, which is costly and complicated to maintain, and has a single function, and the accuracy cannot be improved.
