Embodiment 1

[0041] figure 1 It shows the implementation process of the intelligent supervision method for the behavior of subway construction personnel provided by Embodiment 1 of the present invention. The intelligent supervision method for the behavior of subway construction personnel can be applied to computer equipment, and the computer equipment can be mobile phones, notebooks and other devices that can communicate. Specific not limited.

[0042] The following detailed description of the subway construction personnel behavior intelligent supervision method provided by Embodiment 1 of the present invention is as follows:

[0043] In step S100, a sample video file in the target area is obtained, and the sample video file is divided into several sample picture frames.

[0044] In the above step S100 provided by Embodiment 1 of the present invention, it is possible to divide according to the areas that need to be monitored on the subway construction site, set the target area that needs ...

Embodiment 2

[0054] The intelligent supervision method for the behavior of subway construction personnel provided by Embodiment 2 of the present invention also includes:

[0055] Step S400, acquire a real-time video file in the target area, and divide the real-time video file into several real-time picture frames.

[0056] In the above step S400 provided by Embodiment 2 of the present invention, the target area is recorded by video recording equipment, and the behavior of construction personnel and the operation of construction machinery in the target area are recorded in real time, so as to obtain real-time video files in the target area. ;

[0057] Step S500, use the behavior detection model to detect the predetermined target and its feature information in each of the real-time picture frames, and obtain the corresponding subway construction behavior category and detection score, and the real-time picture corresponding to the highest detection score in several consecutive frames is the k...

Embodiment 3

[0068] figure 2 Shown is the composition structure frame of the intelligent supervision system for the behavior of subway construction personnel provided by Embodiment 3 of the present invention, and the intelligent supervision system 10 specifically includes:

[0069] The sample video acquisition module 11 is configured to acquire a sample video file in the target area, and divide the sample video file into several sample picture frames.

[0070] The first selection module 12 is configured to select a sample picture frame containing a predetermined target as a training sample.

[0071] The training module 13 is used to randomly divide the training samples into two groups, and use the first group of training samples to perform the first training on the behavior detection model to determine the parameters of the behavior detection model; based on the parameters of the behavior detection model, Using a second set of training samples to perform second training on the behavior d...

Abstract

The embodiment of the invention relates to a construction supervision method and system, in particular to a subway constructor behavior intelligent supervision method and system. The method comprisesthe following steps: acquiring a real-time video file in a target area, and segmenting the real-time video file into a plurality of real-time picture frames; detecting a predetermined target and feature information thereof in each real-time picture frame by using a behavior detection model to obtain a corresponding subway construction behavior category and a detection score, and taking the real-time picture corresponding to the highest detection score in a plurality of continuous frames as a key frame; selecting a video file containing the preset video length of the key frame in the real-timevideo file as a key video clip; and outputting the key video clip, and outputting the construction behavior category corresponding to the predetermined target and the feature information thereof in the key video clip so as to supervise the subway constructors, thereby ensuring that the subway constructors on the construction site can be effectively supervised.

Description

technical field [0001] The embodiment of the present invention relates to a method and system for construction supervision, in particular to a method and system for intelligently supervising the behavior of subway construction personnel. Background technique [0002] At present, with the rapid development of urbanization in our country, the scale of urban infrastructure construction is also continuously increasing, but the resulting problems are that the safety management of construction enterprises is not strict, the technology is backward, and the safety awareness of employees is poor. It has existed for a long time, and the safety production situation of construction projects is still severe. [0003] According to the experience of previous subway construction projects, engineering accidents are mostly caused by unsafe behaviors of front-line construction workers. The most effective measures for engineering safety production accidents. [0004] At present, the field of ...
