[0064] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0065] With the advancement of technology, the hardware performance of smart terminals is becoming more and more powerful, and the software functions are becoming more and more abundant. Traditional image acquisition devices are usually SLR cameras and video cameras, which are not only single-function but also inconvenient to carry.

[0066] Nowadays, smart terminals have integrated image acquisition devices. In addition to basic shooting functions, they can also conduct financial transactions by scanning "transaction codes" and conduct identity verification by scanning "verification codes".

[0067] However, whether scanning the "transaction code" or the "verification code", it is just scanning a "QR code" with a single function and poor user experience.

[0068] The target object recognition method, device, electronic device and computer-readable storage medium provided in the present application are intended to solve the above technical problems in the prior art.

[0069] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0070] In one embodiment, a method for identifying a target object in a smart terminal is provided. Figure 1 As shown, the method includes:

[0071] Step S101, when a control instruction to enter a scanning mode is received, the image acquisition device of the smart terminal is controlled to start and enter the scanning mode;

[0072] In actual applications, the user can enter the scanning mode by opening the application in the smart terminal, for example, the user opens "360 Mobile Guard" and then clicks the shortcut of "Secure Scan", or the user opens "Camera" and then clicks the shortcut of "Scan". The user can also enter the scanning mode by one or more physical buttons of the smart terminal without opening the application. Among them, the smart terminal can have the following characteristics:

[0073] (1) In terms of hardware system, the device has a central processing unit, memory, input components and output components, that is, the device is often a microcomputer device with communication function. In addition, it can also have multiple input methods, such as keyboard, mouse, touch screen, microphone and camera, and the input can be adjusted as needed. At the same time, the device often has multiple output methods, such as receiver, display screen, etc., which can also be adjusted as needed;

[0074] (2) In terms of software system, the device must have an operating system, such as Windows Mobile, Symbian, Palm, Android, iOS, etc. At the same time, these operating systems are becoming more and more open, and personalized applications developed based on these open operating system platforms are emerging in an endless stream, such as address books, calendars, notepads, calculators, and various games, which greatly meet the needs of personalized users;

[0075] (3) In terms of communication capabilities, the device has flexible access methods and high-bandwidth communication performance, and can automatically adjust the selected communication method according to the selected service and the environment, so as to facilitate user use. The device can support GSM (Global System for Mobile Communication), WCDMA (Wideband Code Division Multiple Access), CDMA2000 (Code Division Multiple Access), TDSCDMA (Time Division-Synchronous Code Division Multiple Access), Wi-Fi (WIreless-Fidelity) and WiMAX (Worldwide Interoperability for Microwave Access), etc., so as to adapt to various network standards, support not only voice services, but also various wireless data services;

[0076] (4) In terms of functional use, the equipment pays more attention to humanization, personalization and multi-functionality. With the development of computer technology, the equipment has moved from a "device-centric" model to a "people-centric" model, integrating embedded computing, control technology, artificial intelligence technology and biometric authentication technology, fully reflecting the people-oriented purpose. Due to the development of software technology, the equipment can adjust the settings according to personal needs and become more personalized. At the same time, the equipment itself integrates a lot of software and hardware, and its functions are becoming more and more powerful.

[0077] The so-called scanning mode is to control the image acquisition device of the smart terminal to identify the target object. Specifically, for example, after the user opens the "360 Mobile Guardian", he clicks the shortcut of "Safe Scan Code". At this time, the smart terminal receives the control command to enter the scanning mode, and then the smart terminal can call the image acquisition device, such as a camera, to collect images. Of course, in addition to calling the image acquisition device of the smart terminal itself, you can also call an external image acquisition device connected (including wired connection, wireless connection) to the smart terminal, or other forms of image acquisition devices, and this application does not limit this.

[0078] Step S102, acquiring a preview image containing the target object through the image acquisition device;

[0079] The preview image is the image captured by the viewfinder after the image acquisition device is turned on. For example, after the camera in the smart terminal is turned on, the screen of the smart terminal is equivalent to the "viewfinder". The image captured by the camera will be transmitted to the screen, and the screen can display the image to the user. At this time, the image the user sees on the screen is the preview image.

[0080] The target object can be the object scanned by the user, such as an icon, a cup, etc. Generally speaking, when the user is scanning, the preview image will not be entirely the target object, and there will be more or less other content, such as the background, etc. Therefore, in actual applications, the preview image obtained by the image acquisition device only needs to include the target object.

[0081] Step S103, determining whether the preview image has specific features;

[0082] In the present application, a specific feature library may be preset, which includes multiple specific features. The specific feature may be an identifier presenting a specific shape. The specific shape may include, for example, "8", "eight", "00", "oo" and similar shapes. The preset specific feature library may include a preset specific feature library locally in the smart terminal, or a preset specific feature library in a remote server.

[0083] In a preferred embodiment of the present invention, the step of determining whether the preview image has a specific feature includes:

[0084] Extracting the target object from the preview image using a target detection model;

[0085] Extracting attribute features of the target object;

[0086] Matching the attribute feature with any specific feature in a preset specific feature library;

[0087] If the matching degree between the attribute feature and any specific feature exceeds a predetermined matching degree threshold, it is determined that the preview image has the corresponding specific feature.

[0088] Specifically, after the image acquisition device obtains the preview image, the object detection model can be used to extract the target object from the preview image. In simple terms, the target object is distinguished from the background. For example, the user wants to scan a cup, but the image acquisition device obtains a preview image with a messy background in addition to the cup. Then the cup can be extracted from the preview image through the object detection mode, and the messy background is filtered out. Then the attribute features of the target object are extracted, wherein the attribute features of the target object can be an identifier presenting any shape. After the identifier of the shape of the target object is extracted, it can be matched with any specific feature in the preset specific feature library. If the matching degree of the two does not exceed the predetermined matching degree threshold, the matching continues until the matching degree of the attribute features of the target object and all the specific features in the preset specific feature library does not exceed the predetermined matching degree threshold, then it can be determined that the preview image does not have the corresponding specific feature; if in the process of continuous matching, the matching degree of the attribute features of the target object and a specific feature in the preset specific feature library exceeds the predetermined matching degree threshold, then there is no need to continue matching, and it can be determined that the preview image has the corresponding specific feature.

[0089] Furthermore, after determining that the preview image has the corresponding specific feature, the attribute feature can be stored in a preset specific feature library, so that the preset specific feature library can be updated and expanded, thereby improving the accuracy of the judgment.

[0090] Step S104: If yes, display the corresponding special effect animation based on the specific feature.

[0091] In the present application, a special effects animation library can also be preset, which includes multiple special effects animations. After determining that the preview image has corresponding specific features, a special effects animation can be randomly selected from the preset special effects animation library for display, or the association relationship between each special effects animation and each specific feature can be established in advance. After determining that the preview image has corresponding specific features, the special effects animation is obtained and displayed based on the association relationship. Among them, the preset special effects animation library can be a preset special effects animation library locally in the smart terminal, or a preset special effects animation library in a remote server; the special effects animation can be in the form of 2D video, 3D video, GIF picture, etc.

[0092] Furthermore, the attribute characteristics of the target object may include at least one of the size, coordinates, and color of the target object in addition to the mark presenting any shape. Of course, in addition to these attribute characteristics, more attribute characteristics may also be included.

[0093] After displaying the special effects animation, the user can also customize the displayed special effects animation based on the attribute characteristics of the target object, generate and display a customized special effects animation. The user can also store the generated customized special effects animation in the preset special effects animation library. If it is stored in the local preset special effects animation library, then the user can display the customized special effects animation when scanning in the future; if it is stored in the preset special effects animation library of the remote server, then other users can obtain the special effects animation made by the current user based on the specific characteristics and attribute characteristics of the target object when scanning the target object, thereby realizing the sharing of customized special effects animation and improving the user experience.

[0094] In the embodiment of the present invention, when the smart terminal receives a control instruction to enter the scanning mode, the image acquisition device of the smart terminal is controlled to start and enter the scanning mode, and then a preview image containing the target object is obtained through the image acquisition device, and it is determined whether the preview image has specific features. If so, the corresponding special effect animation is displayed based on the specific features. Through the above method, the real target object can be converted into a virtual special effect animation, which improves the user experience.

[0095] Furthermore, users can create customized special effects animations based on the attribute characteristics of the target object and the displayed special effects animations, and share them, which increases the diversity of special effects animations and further enhances the user experience.
