Problems solved by technology

[0002] At present, the recognition rate of the technology for identifying the wearing condition of the helmet in the image is about 80%, and the application effect is generally good. However, the existing technology needs to use a high-definition camera and special hardware with high cost, and the overall cost is relatively high.
The resolution of the video system of ordinary user units varies, and the number of security cameras in social units is large, which are specially used for video recording and implementation preview, and are used full-time in the security field, which cannot meet the needs of image resolution in helmet recognition technology

Abstract

The invention provides a low-resolution image safety helmet recognition method and device. The method comprises the steps: carrying out edge feature extraction processing on two continuous image samples; comparing the processed two frames of image samples to identify an image change area; identifying a human body shape area in the change area of the next frame of image sample; carrying out characteristic analysis on a human body shape area to identify the safety helmet, utilizing an edge characteristic extraction technology and color and shape analysis to compare change areas of two continuousframes of images. The requirement for image quality is low, safety helmet identification can be carried out under the condition that the resolution ratio is very low, the requirement for system analysis hardware is lowered, and universality and adaptability are achieved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a safety helmet recognition method and device for a low-resolution image. Background technique [0002] At present, the recognition rate of the technology for identifying the wearing condition of the helmet in the image is about 80%, and the application effect is generally good. However, the existing technology needs to use a high-definition camera and special hardware with high cost, and the overall cost is relatively high. The resolution of the video system of ordinary user units varies, and the number of security cameras in social units is large, which are specially used for video recording and implementation preview, and are used full-time in the security field, which cannot meet the needs of image resolution in helmet recognition technology. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a low-resolution ...
