Embodiment 1

[0034] This implementation provides a prefabricated building construction navigation method based on machine vision, which solves the problems of long working hours, low work efficiency and poor accuracy when assembling prefabricated parts in the prior art, such as figure 1 As shown, the method includes the following steps:

[0035] S01: The 3D laser scanning unit conducts 3D laser scanning of the prefabricated parts to be assembled and the target construction site to obtain 3D data; among them, the 3D laser scanning unit performs coordinate transformation on the scanned 3D data of the prefabricated parts to be assembled and the target construction site, so that they are located in the same In the coordinate system; at the same time, the environmental factors in the three-dimensional data, such as pedestrians, etc. are removed.

[0036] S02: The modeling unit based on BIM technology respectively establishes the three-dimensional models of the prefabricated parts to be assemble...

Embodiment 2

[0048] This embodiment has the same inventive concept as Embodiment 1, and is further optimized on the basis of Embodiment 1. It provides a prefabricated building construction navigation system based on machine vision. The system includes: a three-dimensional laser scanning unit, A modeling unit, a path calculation unit, a wireless communication unit, an intelligent control unit, a tower crane control unit, an image acquisition unit, a second wireless communication unit, a display unit, a detection unit and a power supply unit.

[0049] Further, the 3D laser scanning unit outputs the scanned prefabricated parts and the 3D data of the target construction site to the intelligent control unit, and the intelligent control unit outputs the 3D data of the target construction site to the modeling unit.

[0050] Further, the modeling unit builds three-dimensional models of the prefabricated parts to be assembled and the target construction site and outputs them to the intelligent contr...

Abstract

The invention discloses an assembly building construction navigation method based on machine vision, and belongs to the technical field of assembly building hoisting. The assembly building construction navigation method includes the steps: a three-dimensional laser scanning unit obtains three-dimensional data of a to-be-assembled prefabricated part and a target construction site; a modeling unit builds three-dimensional models of the to-be-assembled prefabricated part and the target construction site correspondingly; a path calculation unit calculates an optimal predetermined path for assembling of the to-be-assembled prefabricated partthrough an ant colony algorithm; a tower crane control unit controls a tower crane to install the to-be-assembled prefabricated part with the optimal predetermined path; a detection unit detects whether any deviation exists in the position of the assembled prefabricated part or not, and if yes, the tower crane control unit adjusts the assembled prefabricated part; and if not, the next prefabricated part continues to be installed in the way. According to the assembly building construction navigation method based on the machine vision, the problems oflong working time, low working efficiency and poor accuracy when assembling prefabricated parts in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of prefabricated building hoisting, in particular to a machine vision-based navigation method for prefabricated building construction. Background technique [0002] Energy conservation and emission reduction is an inevitable requirement to promote the adjustment and transformation of the economic structure and realize the sustainable development of the economy and society. Prefabricated buildings refer to buildings assembled from prefabricated parts on site. Their design meets the requirements of building functions and performance, and meets the design principles of sustainable development and green environmental protection. It is increasingly used in construction projects in my country. [0003] At present, the hoisting of prefabricated buildings is mainly based on manual hoisting, and manual hoisting has a series of problems. Human subjective factors affect the accuracy of hoisting. The hoisting site works...
