Abstract

The invention discloses a safety helmet wearing detection method and device based on single-model prediction. The method comprises the following steps: inputting an original image into a deep convolutional neural network, extracting apparent characteristics of the original image from different layers of the deep convolutional neural network, and acquiring characteristic graphs of different scalesfrom the apparent characteristics by adopting a characteristic pyramid network; respectively inputting the feature maps of different scales into a coordinate regression network and a pedestrian recognition network, respectively outputting the position of a pedestrian target detected in the original image and the confidence of recognition, finding an optimal target bounding box through a non-maximum suppression method, and eliminating redundant bounding boxes; inputting the feature maps of different scales into a safety helmet wearing classification network based on an attention mechanism, andfinally obtaining a detection result whether the pedestrian target wears the safety helmet or not. Whether a worker wears a safety helmet or not in workplaces such as a factory area and a constructionsite shot by a monitoring camera is accurately recognized through a single model.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a safety helmet wearing detection method and device based on single model prediction. Background technique [0002] Wearing safety helmets is a basic safety precaution requirement in workplaces such as high temperature, power supply lines, factory areas and construction sites, and is closely related to the personal safety of construction workers. The traditional method of manual supervision will not only consume too much manpower, but also the complexity of the workplace makes supervision very difficult, which leads to frequent safety accidents caused by construction workers not wearing safety helmets. In response to this problem, it is of great necessity and practical value to use advanced artificial intelligence technology to automatically identify whether construction workers wear safety helmets. In recent years, object detection methods based on deep convolutional neural netwo...
