Abstract

The invention belongs to the field of tunnel safety construction, and provides a construction safety judgment method and system based on video information behavior pattern recognition. The method comprises the following steps: acquiring a color image and a depth image of personnel in a set working area and a tunnel construction effect picture; extracting face feature information in the color image and determining the identity of a person according to the matching degree of the face feature information and a preset face feature template, and then tracking the person to judge whether the person with the determined identity leaves a normal working area; extracting human skeleton node information in the depth image of which the identity is determined, identifying personnel behaviors based on a behavior discrimination model, comparing the personnel behaviors with violation behaviors in a violation information base, and judging the violation behaviors of the personnel in real time; and based on the tunnel construction effect drawing and the construction effect inspection model, judging whether the current tunnel construction accords with an expected scheme or not in real time.

Description

technical field

[0001] The invention belongs to the field of tunnel safety construction, and in particular relates to a construction safety discrimination method and system based on video information behavior pattern recognition. Background technique

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Due to the complex tunnel construction environment, relatively high risks, and difficult management, whether it is the failure or illegal use of tunnel construction equipment, or the irregular construction of workers, it will have a major impact on the safe construction of the tunnel. How to ensure the safety of personnel in the tunnel? , safe construction of equipment, ensuring the specification and quality of tunnel construction, and strengthening personnel management have become issues of concern to the current construction party.

[0004] Due to the limitations ...
