Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, the present invention discloses a thermal infrared human body target recognition method based on a monotone wave direction energy histogram, comprising the following steps:

[0037] (1) Obtain a thermal infrared image containing a human target;

[0038]Thermal infrared images include static images or sequence images, and a thermal infrared camera (or other thermal infrared imaging device) is used to collect static images or sequence images. The minimum distance setting between the imaging device and the human body of interest ensures that the imaging size of the human body of interest does not exceed the maximum resolution of the image, and the maximum distance setting ensures that all or part of the body parts of the human body...

Abstract

The invention discloses a thermal infrared human target recognition method based on a monotone wave direction energy histogram, comprising the following steps: acquiring a thermal infrared image containing a human target; extracting a candidate human target area from the thermal infrared image, and the candidate human target area is Refers to the image area suspected to contain a human target in the thermal infrared image; extracting the monotonic wave direction energy histogram feature of the candidate human target area; classifying and identifying the candidate human target area based on the monotonic wave direction energy histogram feature, and determining A candidate human target area containing a human target realizes the recognition of the human target in the thermal infrared image. The monotonic wave direction energy histogram feature realizes a good expression of the fuzzy edge of the thermal infrared image under strong noise interference, so it has a strong distinction. Using the monotonic wave direction energy histogram feature to realize human target recognition can effectively improve human target recognition. Accuracy of recognition.

Description

technical field [0001] The invention relates to the technical field of digital image processing and pattern recognition, in particular to a thermal infrared human target recognition method based on a monotone wave direction energy histogram. Background technique [0002] Human target recognition technology is widely used in battlefield reconnaissance, intelligent transportation, security monitoring, intelligent robots and many other fields. In recent years, with the advancement of the technical level of thermal infrared imaging equipment and the continuous decline of prices, more and more researchers have carried out research on human target recognition technology under thermal infrared imaging conditions. Thermal infrared imaging equipment performs imaging by detecting the thermal radiation of objects in the environment, so it can work normally in the case of poor lighting or even no visible light. Therefore, the human target recognition application system using thermal inf...
