AI Technical Summary

Technical Problem

In existing construction safety management, manual inspections are limited in frequency and highly subjective, making it difficult to promptly detect hidden dangers such as missing edge protection or damaged protective facilities. Furthermore, video recognition solutions are easily affected by changes in lighting and obstructions, making it difficult to accurately obtain three-dimensional geometric parameters and determine the configuration of protective facilities.

Method used

Data is collected simultaneously using radar and depth cameras to generate a 3D point cloud model. Candidate areas for hazardous sources are extracted through plane fitting and boundary detection. A theoretical list of hazardous sources is generated by combining the BIM model and construction schedule. Spatial matching is performed to identify protective facilities, calculate a comprehensive risk score, and generate early warning information.

Benefits of technology

It has enabled intelligent, standardized and closed-loop safety management of construction sites, improved the accuracy and anti-interference ability of edge protection detection, and reduced the false alarm and missed alarm rates.

Abstract

This invention discloses a compliance detection method for edge protection in building scenarios based on integrated radar and visual systems, belonging to the field of building construction safety management technology. The method collects target area data to generate a 3D point cloud model; performs planar fitting, boundary abrupt change detection, and region segmentation on the 3D point cloud model to extract candidate hazard source regions and generate hazard source objects; analyzes the BIM model, floor plan, and construction schedule to generate a theoretical hazard source list, and performs spatial matching with the hazard source objects; generates a set of target protection facilities based on the hazard source object type, geometric parameters, construction stage, and standard rule base; identifies the actual set of protection facilities and obtains compliance judgment results; combines hazard level, missing value, non-compliance, personnel risk, environmental interference factors, and rectification factors to calculate a comprehensive risk score and identification credibility, generating early warning information and rectification work orders. This method provides a compliance detection method for edge protection in building scenarios based on integrated radar and visual systems.
