[0103] Based on the first embodiment, a second embodiment of the identification method of the present invention is proposed. In this embodiment, after step S11 and before step S12, the identification method further includes the following steps:
[0104] Step S17: Evaluate the image quality of the image to be recognized to obtain an image quality evaluation value.
[0105] The image quality evaluation value is used to characterize the image quality, and the larger the image quality evaluation value is, the better the image quality is.
[0106] In this embodiment, the image to be recognized may be input into the image quality assessment model to obtain an image quality assessment value. Wherein, the image quality evaluation model is a pre-trained neural network model for evaluating image quality.
[0107] Step S18: judging whether the image quality evaluation value is greater than a preset image quality threshold.
[0108] The preset image quality threshold is a preset image ...

The invention discloses an identity recognition method applied to a monitoring system comprising at least two cameras, and the method comprises the steps: obtaining a to-be-recognized image collectedby the cameras at a preset moment; determining a to-be-recognized human body from the to-be-recognized image, and according to the human body features of the to-be-recognized human body, obtaining personnel meeting a preset condition from a preset human body feature database to obtain a candidate personnel set; and judging whether the to-be-recognized human body is matched with a candidate personor not according to a preset image feature set. According to the human body identification method and device, the candidate person set is determined according to the human body characteristics of theto-be-identified human body, and then the final identification result is determined from the candidate person set according to the preset image characteristic set, so that the accuracy of identity identification is improved. The invention further discloses an identity recognition device, terminal equipment and a storage medium, and the accuracy of identity recognition is improved.
Description
technical field [0001] The present invention relates to the field of image processing, in particular to an identity recognition method, device, terminal equipment and storage medium. Background technique [0002] With the continuous improvement of national security requirements, identification technology is becoming more and more popular. For example, for a surveillance system, it is necessary to identify the identity of the person appearing in the surveillance video. Traditional identification solutions based on video analysis may cause low identification accuracy due to scenarios such as people unintentionally lowering their heads, mutual occlusion during activities, uneven light distribution, different camera angles and image quality, and close seasonal clothing. [0003] Therefore, in the existing identification methods, there is a problem of low identification accuracy. Contents of the invention [0004] The main purpose of the present invention is to provide an ide...
