Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In a specific embodiment, the image processing method provided in the embodiment of the present disclosure may be applied to a terminal, optionally, the terminal may include but is not limited to an access control device, an attendance device, a cash register device, and the like, optionally, the access control device, the attendance device, the cash register device, and the like are provided with a camera device, optionally, the camera device may be a camera device integrated with the terminal, and may also be a split camera device connected in a wired or wireless manner.
Fig. 1 is a flowchart illustrating an image processing method according to an exemplary embodiment, which is used in a terminal, as shown in fig. 1, and specifically, the image processing method includes:
s101: in response to the first object recognition instruction, a first object image and a target reference image of a target object acquired by the local device are acquired.
In practical applications, the first object recognition instruction may be triggered based on different triggering operations in combination with different requirements of practical applications. In an alternative embodiment, the first object recognition instruction may be triggered based on an acquisition operation of the target object; for example, a button for triggering shooting of a face image of a user is arranged on the access control device, and accordingly, the operation of acquiring the face image of the user can be executed by triggering a camera device on the access control device through pressing the button, and correspondingly, the first object identification instruction can be triggered while the camera device executes the operation of acquiring the face image of the user, so that local equipment can be called to acquire a first object image (including an image of a target object) of the target object, and a target reference image can also be acquired.
In a specific embodiment, the target reference image is obtained by updating a registration image based on the local object image, specifically, the registration image is an image of a target object acquired by the remote device, and the registration image may be used for object registration. In particular, the local object image may be an object image acquired by the local device. In practical applications, the target reference image may be obtained in advance, that is, obtained before the first object recognition instruction is triggered, and stored in a corresponding database or cache, and after the first object recognition instruction is triggered, the target reference image is read from the corresponding database or cache. Specifically, the target reference image may be a reference image for identifying the target object. In a specific embodiment, an object image satisfying a preset condition in the local object image may be selected to update the registration image, so as to obtain the target object image. Accordingly, the target reference image (i.e., the object image satisfying the preset condition) may include at least one of:
selecting a first object image with the similarity with the registered image being more than or equal to a preset threshold value from the local object images;
selecting an object image, wherein the similarity between a first image and a registered image is greater than or equal to a preset threshold value, and the image quality analysis result meets a preset quality condition;
the similarity between a first image selected from the local object images and the registered image is greater than or equal to a preset threshold value, and the orientation information of the target object relative to the camera device is at least one object image of appointed orientation information when the local object images are collected;
selecting a first object image which has similarity with the registered image greater than or equal to a preset threshold value and is matched with the acquisition time attribute information of the registered image according to the time attribute information during the acquisition of the local object image;
the similarity between a first image selected from the local object images and the registered image is greater than or equal to a preset threshold, the time when the local object images are collected is the object image in a target time period, and the target time period is a time period when the execution frequency of preset operation is greater than or equal to a preset frequency;
selecting an object image with the highest similarity with the registered image from the local object images;
and selecting the object image with the highest sum of the similarity with the registered image and the weighted average of the corresponding numerical values of the living body detection results from the local object images.
In addition, it should be noted that the local device may be the terminal provided with the camera device integrated with the terminal or separated from the terminal.
In practical applications, the target object may be different according to different practical application scenarios, for example, in an application scenario that needs face recognition, the target object may be a face of a certain user; for example, in an application scenario requiring iris-based recognition, the target object may be an iris of a certain user; for example, in an application scenario requiring fingerprint-based identification, the target object may be a fingerprint of a certain user. Accordingly, different types of target objects can also adopt different types of camera devices to acquire corresponding object images.
In an optional embodiment, the method may further include: optionally, assuming that the target reference image is an object image with a similarity between a first selected local object image and the reference image being greater than or equal to a preset threshold, as shown in fig. 2, the step of obtaining the target reference image in advance may include:
s201: and acquiring a second object image registration image of the target object acquired by the local equipment in response to the second object identification instruction.
S203: carrying out object recognition on the second object image based on the registered image to obtain a second object recognition result;
s205: and under the condition that the second object identification result indicates that the similarity between the second object image and the registered image is greater than or equal to a preset threshold value, updating the registered image based on the second object image to obtain a target reference image.
In a particular embodiment, the local object image may be an object image acquired by a local device. In some embodiments, the second object recognition instruction may be an object recognition instruction triggered before the first object recognition instruction. Specifically, when the second object recognition instruction is triggered, the reference image as the recognition target object may be the above-mentioned registered image.
In practical application, after the second object identification instruction is triggered, the operation of acquiring the second object image of the target object and the registration image of the target object, which are acquired by the local device, is executed, and the registration image is updated based on the second object image to obtain a target reference image; corresponding operations can be executed based on the second object recognition result in combination with actual application requirements, for example, operations of opening a door control, inputting attendance information, paying and the like are executed under the condition that the second object recognition result indicates that the similarity between the second object image and the registration image is greater than or equal to a preset threshold value.
In an embodiment of the present specification, the second object recognition result may be a similarity between the registration image and the second object image.
