The embodiment of the invention discloses a living body flow direction discrimination method and device based on thermal imaging, equipment and a storage medium. The method comprises steps of acquiring multiple target images, wherein the multiple target images are living body detection images of target positions detected by thermal imaging equipment at multiple continuous moments, and the pixel value of each pixel point of the living body detection images is the temperature value detected by the thermal imaging equipment; determining a target feature vector according to the plurality of targetimages; taking the target feature vector as the input of a living body flow direction discrimination model, wherein the living body flow direction discrimination model is used for discriminating theflow direction of the living body; and obtaining a direction discrimination result value output by the living body flow direction discrimination model, and determining the living body flow direction of the target position at the multiple continuous moments based on the direction discrimination result value. According to the method, the living body flow directions of the multiple target images aredetermined, the problem of privacy leakage is avoided, and the method has high generalization ability.
Description
technical field [0001] The present invention relates to the technical field of image discrimination, in particular to a thermal imaging-based living body flow discrimination method, device, equipment and storage medium. Background technique [0002] Transportation, security, public safety and other fields have a wide range of application requirements for detecting the flow of living bodies. However, the traditional detection of living body flow direction is based on two-dimensional or three-dimensional visual images, which requires high computing performance of living body flow detection equipment, resulting in high equipment costs, and there is a problem of privacy leakage in two-dimensional or three-dimensional visual images. Contents of the invention [0003] Based on this, it is necessary to address the above problems and propose a method, device, equipment, and storage medium for identifying the flow direction of a living body based on thermal imaging. [0004] In th...
