Problems solved by technology

At present, the container terminal yard has a large area, and there are many types of operating vehicles and complex vehicle conditions. For large-scale operating sites, the deployment and management of mechanical equipment is very important. Relying on people is easy to cause fatigue and negligence, and relying on traditional wireless walkie-talkies to issue operations There are many inconveniences in ordering and transmitting production information, which greatly affects the operation efficiency
Obviously, the current "civil defense" measures have been unable to effectively avoid the occurrence of the above-mentioned accidents

Embodiment Construction

[0084] In order to make the objectives, technical solutions, and advantages of the present invention clearer and clearer, the technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0085] Such as figure 1 (a), 1(b), 1(c), figure 2 As shown, the container truck autonomous tracking and anti-lifting early warning method based on machine vision tracking includes the following steps:

[0086] Step 1. The first camera 1 and the second camera 2 collect the video image at the current time t, and obtain the video image of the field of view corresponding to the container truck 3, where image.width is the width of the video image, and image.height is the video Image height.

[0087] Step two, such as image 3 As shown, the lower half of the image in the selected field of view is the tracking area of ​​interest, and the tracking sub-areas box_1, box_2, and box_3 are defined in the trackin...

Abstract

The invention discloses an anti-lifting system for container trucks based on machine vision tracking, which includes a tire crane, a camera, a container truck, a container, a video alarm machine, and control equipment in a central control room. Flush with the frame of the container truck, the field of view of the camera is perpendicular to the direction of travel of the container truck; the camera inputs the video images obtained by tracking to the video alarm machine, and the video alarm machine adopts a tracking algorithm based on fast Fourier transform online learning to obtain The video image is processed, and when it is determined that the container truck is hoisted, an alarm signal is sent to the control equipment in the central control room. The system can automatically detect whether the container is separated from the container truck, so as to avoid human error from lifting the container container truck by mistake, and realize the safety pre-control of the container yard operation.

Description

Technical field [0001] The invention belongs to the technical field of intelligent anti-lifting of container trucks, and in particular relates to a container truck autonomous tracking and anti-lifting early warning method based on machine vision tracking. Background technique [0002] With the rapid development of global container transportation, modern container terminals and yards are increasingly busy and the working environment is becoming more and more complex. Currently, gantry cranes or tire cranes are commonly used to lift containers. Due to the particularity of container loading and unloading operations, incidents of container trucks being lifted by the container often occur during loading and unloading due to the incomplete opening of the lock pins of the container trucks. When using tire cranes for container hoisting operations on the yard, it can generally be divided into the following three working conditions: (1) The container and the container truck are separated. ...
