Problems solved by technology

This method of operation has the following problems: 1) the container lock is prone to omissions during the disassembly process, and the lock that has not been disassembled correctly cannot be loaded correctly, which will increase the hidden danger of accidents; 2) it is necessary to further manually judge the locks at the four corners of the container Whether the buckle is disassembled correctly will greatly increase the workload of the operator, and has the disadvantage of time-consuming and labor-intensive

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] A container lock detection and early warning method based on deep learning, which can automatically identify and alarm locks, reduce the burden on operators, and avoid accidents caused by human negligence. The overall steps are:

[0042] Step 1. Use the detection method of the box corner and the calibration method of the far corner box corner to obtain the accurate positions of the near corner and the far corner of the container; because the relationship between the lock and the box corner is that the lock is directly below the box corner, so use This geometric relationship is used to determine the possible position of the lock;

[0043] Such as Figure 1~4 The shown container corner detection method can realize fast and accurate positioning of the container corner position. The detection objects include the near corner corner...

Abstract

The invention discloses a container lock detection and early warning method based on deep learning. Firstly, the container corner is detected through the deep learning method, and then the far corner corner is detected and calibrated. Finally, the HOG feature extraction and classifier classification judgment are performed. Whether there is a lock; if there is a lock, the alarm will be given by the warning light or the warning sound, and the container will be stopped immediately, and the lock will be removed manually. The invention has the advantages of high automatic detection efficiency of container locks and accurate early warning, can greatly reduce the work intensity of operators, avoid safety accidents caused by human negligence, and can be widely used in containers in the fields of railways, highways, waterways and aviation, etc. transportation industry.

Description

technical field [0001] The invention relates to a method, in particular to a container lock detection and early warning method based on deep learning. Background technique [0002] With the acceleration of China's economic globalization, ports are increasingly becoming the nerve hub of the global comprehensive transportation network. In recent years, with the rapid development of port container business, container transportation has been widely used in ship transportation around the world. In order to ensure the safe and stable delivery of containerized cargo during ship transportation, all containers on board must be locked for transport with some type of locking device. A container latch is a locking device that is conventionally placed at each corner / bottom of a container, each latch being locked to the container below or the deck of the ship (if the container is at the bottom of the stack). [0003] Nowadays, there are many different types of container locks in the fre...
