Construction safety monitoring method and device based on machine vision

Abstract

A method and device for monitoring construction safety based on machine vision. A plurality of peripheral monitoring devices are arranged around the construction area, wherein the peripheral monitoring devices include visible light cameras and infrared cameras; , and send the picture to the management platform, the management platform uses the neural network for analysis, and when an abnormal person or object enters the high-risk area, it will identify and alarm through the neural network. The invention has high recognition rate, wide application scenarios, and can automatically perform recognition and alarm.

Description

technical field [0001] The invention relates to the field of building construction, in particular to construction safety monitoring based on machine vision. Background technique [0002] In the existing technology, the safety of the construction area is achieved by establishing a system and checking by a special person, which cannot be real-time or early warning. [0003] At present, it is also proposed to monitor high-risk areas such as tower cranes and power distribution rooms separately, that is, to monitor individual known areas, such as CN110166751A. However, this method needs to predict which areas are high-risk areas in advance. Although some high-risk areas can be set according to construction experience, and corresponding equipment is specially installed to monitor these areas before construction, this solution still has three disadvantages. : 1. Only some common risk areas can be excluded, and rely on the experience of the construction party. According to a large...

Problems solved by technology

However, this method needs to predict which areas are high-risk areas in advance. Although some high-risk areas can be set according to construction experience, and corresponding equipment is specially installed to monitor these areas before construction, this solution still has three disadvantages. : 1. Only some common risk areas can be excluded, and rely on the experience of the construction party

According to a large number of accident data, although most of the hazards occur in some common dangerous areas, there are still a very large proportion of accidents that occur in other areas that are not known in advance.

2. As the construction progress changes, the location of some high-risk areas will change, so it is necessary to reset the location of the monitoring equipment, which is time-consuming and laborious

3. It is impossible to prevent danger under the condition of poor light

[0007] At present, there is also a way to monitor construction safety through picture comparison, but this kind of comparison generally uses manual comparison, which is time-consuming, laborious and inaccurate; or uses image processing, but each construction site is not exactly the same, so this method is accurate The accuracy is often not high, and manual review is usually required

And no matter which way, a lot of pictures are needed in the database, and collecting pictures is a huge project in itself
