Benefits of technology

The technology described in this patented describes an approach for accurately identifying accidents caused due to various factors such as environmental conditions or workers working under stress during construction work hours. This helps improve efficiency and reduce costs associated therewith.

Problems solved by technology

The technical problem addressed in this patents relates to monitoring and investigating building sites that require frequent maintenance due to their potential hazards or incurrences caused by factors like welders being used at different stages of the project's life cycle. Current methods involve manual checks with human inspectors which can only provide limited data points about specific issues such as poor visibility conditions or lack of knowledge regarding what happened next.

Embodiment 1

[0059] Such as figure 1 As shown, this embodiment provides a method for predicting construction site accidents based on image recognition, including the following steps:

[0060] S1: Obtain the video streaming data of the construction site.

[0061] In the embodiment of the present invention, the video stream data can be collected through the cameras on each construction site.

[0062] S2: Use the preset convolutional neural network to identify security equipment on video stream data in real time to obtain security identification results.

[0063] Among them, the safety identification results include recorded information that workers did not wear safety equipment correctly.

[0064] Optionally, the safety equipment includes safety helmets and safety belts; in step S2, identifying the safety equipment on the video stream data may include: identifying whether each worker included in the video stream data is wearing the safety equipment correctly, if any If the worker does not...

Abstract

The invention discloses a construction site accident prediction method and device based on image recognition, and the method comprises the steps: carrying out the safety equipment recognition of obtained video stream data in real time through a preset convolution neural network, so as to obtain a safety recognition result; performing face recognition and analysis on the video stream data in real time to obtain a face analysis result; inputting the safety identification result, the face analysis result and the climate geographic information of the construction site into a multiple regression equation to obtain an accident occurrence prediction value of the construction site, and identifying a characteristic variable with a relatively large weight in the multiple regression equation as an accident occurrence reason; therefore, the multivariate regression equation can be continuously updated according to the historical accident occurrence numerical value and the historical accident occurrence prediction numerical value, the accident occurrence reason can be identified according to the latest multivariate regression equation, the accident source can be checked, and construction site accident prediction can be carried out from the source.
