System and method for tower crane collision prevention based on graphics recognition technology

Abstract

The present invention especially relates to a system and method for tower crane collision prevention based on a graphics recognition technology, and relates to the tower crane technology field. The system comprises: an image obtaining device configured to obtain image information; a first image processor configured to binaryzation, filtering, edge detection and interest region extraction and collision object extraction processing of an obtained image to complete distance measurement and send a distance measurement result to a control processor; a second image processor configured to perform feature point detection and stereo matching processing of the obtained image to complete distance measurement and send a distance measurement result to a control processor; a sensor group configured to obtain tower crane motion information; the control processor configured to determine whether the collision happens or not according to the distance measurement result and tower crane motion information and emit an alarm instruction in the condition that it is determined that the collision happens; and an alarm device configured to emit alarm information according to the alarm instruction sent by the control processor. The intelligence degree is high, precision is high, and the applicability is wide, etc.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a tower crane anti-collision system and method based on image recognition technology. Background technique [0002] As a main construction machine widely used in construction and installation projects in our country, tower crane is an indispensable and important construction machine for high-rise building construction. With the widespread use of tower cranes, its safety issues cannot be ignored. Secondly, as urban buildings become more and more dense, the density of tower cranes on construction sites is also increasing. Collision accidents between tower cranes and buildings occur frequently. [0003] During the working process of existing tower cranes, there are usually two means of anti-collision: human-controlled anti-collision or acquisition of motion information by sensors for anti-collision. Anti-collision through human control has high requirements for the operat...

AI Technical Summary

Problems solved by technology

Anti-collision through human control has high requirements for the operator's operation skills, and has high limitations. In some complicated cases, it is difficult to avoid collisions through human control.

[0004] The anti-collision method of obtaining motion information through sensors is more intelligent than human-controlled anti-collision, but after the sensor obtains data information, human manipulation is also required to perform anti-collision operations

Prone to collision accidents caused by human error
