Automatic card collecting and positioning booting system based on computer vision technology and application method thereof

Abstract

The invention discloses an automatic card collecting and positioning booting system based on a computer vision technology. The automatic card collecting and positioning booting system comprises a main control computer provided with image processing software, camera shooting equipment which can connect and shoot in real time, a server which is used for storing and provides information of a box to be operated, and a display board for reminding a driver of operating, wherein the main control computer is connected with the server and can obtain information from the server according to an instruction; the main control computer sets a card collecting vehicle positioning target characteristic and a theoretical position thereof by the image processing software in advance; the camera shooting equipment shoots a spot image obtaining target characteristic and a real-time position thereof and transmits the spot image obtaining target characteristic and the real-time position to the main control computer; the real-time position and the theoretical position of the target characteristic are compared and analyzed through the image processing software in the main control computer; a comparison result is displayed through the display board; a driver can finish the positioning of a card collecting vehicle through the prompt of the display board. The automatic card collecting and positioning booting system disclosed by the invention has the advantages that the computer vision technology is utilized; the equipment is simple, the cost is low and the maintenance is convenient; the promotion is simple and clear; the positioning efficiency is high; the automatic card collecting and positioning booting system can work in all weathers.

Description

technical field [0001] The invention relates to the technical field of positioning trucks under container cranes in container terminals or yards, in particular to an automatic guiding system for positioning trucks based on computer vision technology and a method for using the same. Background technique [0002] Computer vision refers to the use of various imaging systems instead of human eyes as input means to identify, track and measure targets, and the computer replaces the brain to further process and analyze the acquired images. It has many similarities with robot vision. The main difference is that computer vision has relatively high requirements for precision, but relatively low requirements for speed and real-time performance. This feature is just in line with the automatic positioning and guidance of trucks. [0003] Whether the container crane's lower truck can be quickly and accurately positioned will not only affect the operating efficiency of the container crane,...

Problems solved by technology

The core component of this kind of system is the laser scanner, the price of this instrument alone is as high as 40,000 to 50,000, and the service life is not long, and the maintenance cost is very high; in addition, the laser scanner has high requirements on the environment, and fog and rain will It will affect the accuracy of the laser scanner, and in the outdoor working environment, the lens of the laser scanner is very easy to adhere to dust, which will affect the normal operation of the laser scanner and the accuracy of positioning. Therefore, the laser scanner needs regular maintenance. Wipe and maintain

[0004] As a non-essential component in the container loading and unloading process, the truck positioning system has a one-time high cost input and high maintenance costs. For its role, the input-output ratio is obviously too low, so a low-priced The integrated truck positioning and guidance system has become an expectation of the industry
