Embodiment 1

[0057] Such as Figure 1 to Figure 3 As shown, the present invention is composed of image acquisition equipment and image processing and recognition equipment. The image acquisition equipment is responsible for capturing the pictures of the safety production site in real time and forwarding them to the image processing and recognition equipment. The image processing and recognition equipment is responsible for preprocessing (noise reduction, enhancement, etc.) on the pictures of the safety production site, and performing human head recognition and identification of whether to wear a helmet.

[0058] The image processing and recognition equipment consists of three parts: image preprocessing module, human head detection module and helmet detection module.

[0059] Image preprocessing, using Gaussian smoothing, median filtering and Fourier forward and reverse transform and other technical means for image preprocessing. Finally, a high-quality, low-noise, and clearly visible ima...

Abstract

The invention discloses a production operator safety helmet wearing detection method based on image processing. The method comprises the following steps: capturing a picture of a safety production site in real time, preprocessing a picture of a safety production field, detecting the head of a human body, searching whether color features of the safety helmet exist in a head range by adopting a color feature analysis method on the basis of a human head detection result, and further detecting whether the safety helmet is worn or not by combining the color feature analysis result with template matching. According to the method, whether a person in a working scene wears the safety helmet or not can be obtained in time, if the dangerous behavior that the person does not wear the safety helmet isfound, an alarm can be given out, and screenshots are captured to reserve evidences. By means of the technical means, the execution force specified by safety management of a production operation siteis enhanced.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an image processing-based method and system for detecting wearing of safety helmets by production workers. Background technique [0002] In industrial safety production management, the safety of on-site workers is particularly important. As an effective safety protection product, safety helmets can well protect the workers' heads from impact objects. However, due to improper management, poor safety awareness and other reasons, the on-site personnel did not wear safety helmets as required, and safety accidents caused by this have also occurred frequently. Therefore, it is of great significance to identify and detect whether operators wear safety helmets, prevent and effectively control illegal operations, and improve the safety, reliability, and economy of related production and operation systems. [0003] At present, the on-site staff's compliance with the regulations ...
