Problems solved by technology

[0006] Since there is no exact position information of the cleaning machine, the above two patents can only send an avoidance alarm or prompt to the cleaning machine, but cannot instruct the operator of the cleaning machine to avoid in that direction, so that the cleaning machine can leave the switch quickly and accurately Area

Embodiment Construction

[0039] The mobile machine vision anti-collision protection system for bulk cargo yard of the present invention is as Figure 4 shown, including:

[0040] A camera device installed on the main equipment, such as a camera, whose field of view covers the yard area where the main equipment operates, to collect images of the yard;

[0041] The identification mark set on the top of the cab of the mobile machine is composed of rectangle A and rectangle B, the two rectangles have a common vertex, and the size of rectangle A and B is obviously different;

[0042]The image processing device receives the image collected by the camera device, and maps the position and direction of the identification mark in the image to the position and direction of the mobile machine in the stockyard plane according to the corresponding relationship between the image plane and the stockyard plane;

[0043] The main equipment controller dynamically calculates the anti-collision protection area according ...

Abstract

The invention discloses a mobile machinery vision anti-collision protection system for a bulk yard and an anti-collision method, which is characterized in that vision technology is adopted to detect mobile machinery, a recognition mark is installed on the top of the mobile machinery, a camera which is installed on a main device is used for collecting an image of the yard, actual position and direction of the mobile machinery can be detected according to the recognition marks in the image, an anti-collision protection area can be dynamically calculated, when the main device interferes the anti-collision protection area of the mobile machinery, the anti-collision protection control is conducted, and a specific avoidance order can be issued when an alarm is issued for the mobile machinery, so that the mobile machinery can leave as soon as possible.

Description

technical field [0001] The invention belongs to mobile machine anti-collision technology, in particular to a mobile machine vision anti-collision protection system and anti-collision method for bulk cargo yards. Background technique [0002] When loading and unloading operations in bulk cargo yards, large-scale equipment and mobile machinery are often used to work together. For example, when the reclaimer is clearing stacks close to the ground, the pusher is used to gather the materials close to the ground for reclaiming, or the loader is used to load the remaining materials into the truck; During operation, trucks are used to transport the materials to the storage yard, and the pusher piles the materials into piles and is grabbed by the door crane; or the door crane unloads materials on the storage yard to form a pile, and the loader loads the materials into the truck. [0003] For the convenience of description, hereinafter, large-scale equipment such as reclaimers and do...
