Three-dimensional positioning method and positioning system for tower crane high-altitude operation based on binocular vision

Abstract

The invention discloses a three-dimensional positioning method and a positioning system for tower crane high-altitude operation based on binocular vision. The positioning method comprises the following steps: S1, a binocular camera collecting a first image and a second image; S2, preprocessing the first image and the second image; S3, using the pyramid model for positioning the marker, and determining the position of the marker; S4, carrying out stereo matching on that target centers of the first image and the second image to obtain parallax information; S5, obtaining that parameters of the binocular camera; S6, calculating that three-dimensional coordinates of the target accord to the parameters of the binocular camera and the parallax information. The invention can realize three-dimensional positioning function of tower crane operation with binocular vision, can real-time monitor and record site operation information, timely and effectively supervise the use process and behavior of the tower crane, effectively control dangerous factors and safety hidden dangers in the operation process of the equipment, and prevent and reduce the occurrence of safety production accidents of the tower crane.

Description

technical field [0001] The invention relates to the technical field of construction operations, in particular to a binocular vision-based three-dimensional positioning method and positioning system for tower crane aerial work. Background technique [0002] The prefabricated building is a building assembled from prefabricated parts and components on the construction site. A large number of building parts in the prefabricated building are produced and processed by the workshop. The types of prefabricated components mainly include exterior wall panels, interior wall panels, laminated panels, balconies, air-conditioning panels, Stairs, prefabricated beams, prefabricated columns, etc. Different from the existing building construction, the cast-in-place operation of the prefabricated building is greatly reduced, and only assembly work is required on site. [0003] The assembly work includes tower crane high-altitude operations. The prefabricated components are hoisted to the corr...

AI Technical Summary

Problems solved by technology

[0003] The assembly work includes tower crane high-altitude operations. The prefabricated components are hoisted to the corresponding stations through the tower hooks and then placed. However, since the operator is in the control room, he cannot visually observe the positions of the tower hooks and the lower stations. In the prior art, it is necessary to pass The observers observe and then inform the operator of the specific location information through the walkie-talkie, but the construction efficiency is still low
