Embodiment Construction
[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0049] refer to figure 1 , the embodiment of the present application provides a method for updating a human face picture, comprising steps:
[0050] S1. Collect the first face picture used for the current face unlocking application program, and the first time for the current face unlocking application program;
[0051] S2. Determine whether the first time between the first time of the current face unlocking of the application and the second time interval of the previous face unlocking of the application is greater than a preset time length;
[0052] S3. If the time inter...

The invention discloses a face picture updating method, a face picture updating device, computer equipment and a storage medium. According to the method, a face picture change trend does not need to be calculated, but is associated with time. When an interval between first time of a current face unlocking application program and second time of a previous face unlocking application program is not greater than a preset time length, the similarity comparison with a first standard face picture is directly carried out without updating the standard face picture. When the interval between the first time when the application program is unlocked by the human face at the current time and the second time when the application program is unlocked by the human face at the previous time is greater than the preset time length; similarity calculation is carried out on the first standard face picture and the second standard face picture; the first similarity and the second similarity are obtained, if the second similarity is larger than the first similarity, it is indicated that the face of the user changes, the second standard face picture with the higher similarity with the current first face picture serves as the default standard picture, and the standard picture is updated more easily and quickly.
Description
technical field [0001] The present application relates to the technical field of image matching, in particular to a face image updating method, device, computer equipment and storage medium. Background technique [0002] Face recognition is a biometric technology for user identity verification based on the user's facial features. Face recognition is widely used in scenarios such as login verification and network event authorization (such as payment authorization). [0003] The process of face recognition is mainly: store the user's standard face picture in the data processing device with face recognition function, the standard face picture is generally the face picture provided by the user when registering, so that the user's face recognition is required , the data processing device can obtain the current face picture of the user, compare the current face picture of the user with the standard face picture, and determine the face If the recognition is passed (that is, the fa...
