Bridge crane hoisting safety anti-collision system and method based on dynamic binocular vision

Abstract

The invention provides a bridge crane hoisting safety anti-collision system and method based on dynamic binocular vision, and the method is based on a binocular vision measurement system and comprisesthe following steps: 1, constructing three-dimensional point cloud information of a target; 2, reconstructing a static obstacle in a crane working scene to obtain a reference sample set; 3, collecting image information of the crane in the load transferring process, comparing the image information with the reference sample obtained in the step 2, and respectively obtaining three-dimensional coordinates of the load and the dynamic obstacle; 4, predicting whether the load collides with the dynamic obstacle or the static obstacle or not according to the three-dimensional coordinates of the load and the dynamic obstacle obtained in the step 3; and 5, controlling the operation of the crane according to the judgment result. According to the method, binocular vision is applied to bridge crane hoisting safety collision avoidance, non-contact performance and high robustness are achieved, the complexity degree of an anti-collision system can be reduced to a large extent, and the working reliability of the system is improved.

Description

technical field [0001] The invention belongs to the field of automatic control of cranes, and in particular relates to an image processing-based safety anti-collision system and method for hoisting bridge cranes. Background technique [0002] During the hoisting operation of the bridge crane, when the operator finds that there may be dangerous people and objects around the hoisting object, he will press the emergency stop button of the crane to realize the emergency stop of the crane operation. However, this conventional operation method is easily affected by the operating state of the operator, and the timing of emergency stop is difficult to grasp, resulting in high safety risks. Contents of the invention [0003] The purpose of the present invention is to provide a safety collision avoidance system and method for hoisting bridge cranes based on dynamic binocular vision, which solves the defects of the existing bridge cranes such as difficult timing of emergency stop and...
