Problems solved by technology

[0003] The performance of the fireproof sealing system depends not only on the performance of the fireproof sealing material itself, but also on the construction technology of the fireproof sealing. Without a good construction technology, no matter how good the fireproof sealing material and construction plan are, they will not be able to exert their maximum effect.

Abstract

The invention relates to a high-rise building fireproof plugging module defect detection device and method based on line structured light, the device comprises a detection device framework, a line laser measuring instrument and a driving motor, a detection device main body adopts an aluminum alloy framework, and the line laser measuring instrument is fixed on a line rail slide block through a mounting rack to realize free sliding on a line rail; the driving motor is a stepping motor. The method comprises the following steps: carrying out three-dimensional modeling on the surface of a fireproof plugging module, converting 3D point cloud data into a two-dimensional color image, extracting the outer contour of an object from the two-dimensional image, registering the outer contour with a standard template, carrying out local color comparison according to a matching result, and judging whether the fireproof plugging module has defects or not according to a color comparison result.

Description

technical field [0001] The invention relates to the technical field of detection of surface defects of fireproof plugging modules, in particular to a device and method for defect detection of fireproof plugging modules of high-rise buildings based on line structured light. Background technique [0002] In high-rise buildings, the fire burning rate of electrical lines is relatively fast, and the burning rate of shaft cables is generally about three times that of horizontal cables. In addition, if a fire occurs in a cable shaft, the "chimney effect" is likely to occur, and the speed of fire spread will be increased several times, eventually becoming a fast channel for fire spread. If the necessary fire blocking measures are lacking, it is very likely to cause the fire to spread and increase the loss of life and property safety. From the perspective of fire prevention, researching fire blocking technology and blocking the penetration holes of electrical lines is an important m...
