Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] refer to figure 1 , the present invention firstly discloses a quay crane guidance system based on image recognition, its main equipment includes image acquisition equipment 2, calibration reference object (or simply referred to as "reference object"), external reference marker 1, cart 3, Handle equipment. The system of the present invention uses an image processing based object recognition sensor system. The target recognition sensor system refers to the image information and spatial distance information of the target captured by the machine vision sensor (such as the image acquisition device 2 and the laser), and the two image acquisition devices 2 are used to collect the images of the calibration reference object and transmit them to the processing device. The processing device obtains the three-dimensional coordina...

Abstract

The invention discloses a guiding system and method for a quay crane cart based on image recognition. The guiding system for the quay crane cart based on the image recognition comprises image acquisition devices, a calibration reference object, external reference marks, a cart and processing equipment. The external reference marks are used for calibrating a world coordinate system and an image coordinate system of the image acquisition devices. The two image acquisition devices are separately used for collecting the images of the calibration reference object and transmit the images to the processing equipment. The processing equipment obtains the three-dimensional coordinate information of the calibration reference object. The processing equipment extracts contour information of a container from the collected images to calculate the position data of the container and obtain the coordinate transformation relationship between the image coordinate system and the world coordinate system ofthe container. The processing equipment calculates the real-time position of the container according to the relationship between the two coordinate systems, and controls the cart to carry out bay-position-changing guiding according to the real-time position. According to the guiding system and method for the quay crane cart based on the image recognition, the working environment of a dock driveris improved, the labor cost of the staff is reduced, and the operation efficiency of the port is improved.

Description

technical field [0001] The present invention relates to a system and a method for guiding a quay crane, and more specifically, to a system and a method for guiding a quay crane based on image recognition. Background technique [0002] During the loading and transportation of a container on a ship, its position information is composed of a 6-character code, called the shell position. The 6-bit character information of the shell is composed of row number, column number and layer number. The first two characters are row (line) numbers, which are composed of Arabic numerals, generally arranged in the order of natural numbers from the bow to the stern; the middle two are column numbers, which are numbered by two Arabic numerals, based on the longitudinal section , use odd numbers for the starboard side, and even numbers for the port side; the last two digits are the floor numbers, which are expressed in numbered form, and the cabin is based on the bottom floor, and the order is ...
