Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] Referring to Fig. 1, the image taken by the camera equipment to calibrate the reference object (such as the position line of the correct parking space) is converted into an electrical signal and transmitted to the computer for processing. According to the principle of monocular vision imaging in the principle of visual perspective imaging, an H matrix is ​​established, and the calibration is Take the mathematical relationship between the coordinates of the object in the image and the coordinate homography of the object in the actual space, and determine the position line equation parameters of the correct parking space in the actual space. After completing the above calibration preparations, start the positioning detection of the container truck coming from opposite sides. After the computer collects the electrical signal of the image of the current co...

Abstract

A locating method for the container trucks in port region includes such steps as taking image, transmitting and acquiring image, scaling in H array, extracting front edge, calculating distance, and outputting and displaying data. Its locating system is composed of high-speed camera head, computer, and electric display screen in the driver cab of container truck.

Description

technical field [0001] The invention relates to a positioning detection technology, in particular to a positioning method and device for a container truck in a port. Background technique [0002] Containers are important equipment in the logistics industry. The loading and unloading of containers is an important link in logistics. The degree of automation of its loading and unloading operations is one of the key factors that determine the efficiency of logistics. At present, the loading and unloading of containers in my country's ports is still in a semi-automatic state. Part of the operations in the container loading and unloading process are realized by crane operations. However, the spatial position of the container relative to the spreader, the spatial position of the container relative to the truck, and the relative position of the container The positioning links such as the spatial position of the container basically rely on manual experience estimation to carry out the...
