[0024] A more comprehensive description of the present disclosure is given below with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are illustrated. The technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the drawings of the embodiments of the present disclosure, and it is obvious that the described embodiments are merely some embodiments of the present disclosure, rather than all embodiments. All other embodiments that can be obtained by those skilled in the art without creative efforts based on the embodiments in the present disclosure should be within the scope of protection of the present disclosure. The technical solutions of the present disclosure are described in various aspects below together with the drawings and embodiments.

[0025] In the related art known by the present inventors, in the actual application of intelligent hardware, there may be multiple applications running simultaneously in the background, all of which need to use the camera. One camera cannot support multiple applications at the same time, and then the collision and abnormality of multiple applications will probably occur. Since the number of cameras of the intelligent hardware is uncertain, and the applications working simultaneously are also uncertain, multiple applications may not be supported due to insufficient cameras, on the other hand, if an intelligent terminal is provided with too many cameras, it will also cause hardware waste.

[0026] In view of this, one technical problem to be solved by the present invention is to provide an image data distribution method and device, a terminal and a storage medium that can distribute image information captured by a camera to multiple web page instances and multiple applications, so that multiple functions are supported simultaneously. In addition, the present invention can overcome the shortcoming in the prior art that one camera can only support one function at the same time, and therefore can reduce hardware costs and improve the user's usage experience.

[0027] FIG. 1 is a schematic flow chart of one embodiment of the image data distribution method of the present disclosure, which is applied to a terminal as shown in FIG.

[0028] Step 101, generating a surface texture instance for processing information captured by an image capture means.

[0029] In one embodiment, the terminal may be an intelligent hardware such as an intelligent entrance guard, an intelligent sound box, and the terminal may also be a mobile phone, etc. The image capturing means may be a video camera, a camera, etc. mounted on the terminal, and image information is captured through the image capturing means. The surface texture instance can process the image information captured through the video camera, the camera, etc. to generate video streaming data, etc.

[0030] Step 102, creating an image capture device instance corresponding to the image capture device.

[0031] Step 103, binding an image capture means instance with a surface texture instance.

[0032] Step 104, generating image data according to the surface texture instances processing the information captured by the image capturing means, the image data including video streaming data, etc.

[0033] Step 105, capturing image data in an interface callback manner by using an image capturing means instance, and delivering the image data to an application and / or a page instance.

[0034] Based on the image data distribution method of the present disclosure, in the case where the video streaming data is captured by one or more cameras, the video streaming data is distributed to multiple web page instances, multiple applications, etc. For example, a terminal is equipped with one camera, and the image information captured by the camera is distributed to multiple web page instances and multiple applications to simultaneously support multiple functions, thus realizing "one camera for multiple applications", in addition, the above method can overcome the shortcoming of the prior art that one camera can only support one function at the same time, and as a result, the hardware cost can be reduced.

[0035] In some embodiments, various approaches may be adopted to generate surface texture instances for processing information captured by an image capture means. Texture instances are created using OpenGL ES (OpenGL for Embedded Systems), and surface texture instances are generated by using the texture instances. OpenGL ES (OpenGL for Embedded Systems) is a subset of the OpenGL three-dimensional graphics API, designed for embedded devices such as mobile phones, PDAs, and game consoles.

[0036] For example, a surface texture instance is / / Create an opgl texture int mInputTexture = OpenGlUtils.createOESTexture(); / / Create a surfaceTexture using the generated texture instance, i.e. set the surfaceTexture to receive the preview data for the camera. SurfaceTexture mSurfaceTexture = new SurfaceTexture (mInputTexture) is created as

[0037] The surface texture instance created by using the texture instance is mSurfaceTexture, which is bound to the camera instead of the SurfaceView, captures the data captured by the camera, and processes the data. The surface texture instance can process the data captured by the camera by using existing methods.

[0038] Various approaches may be adopted to generate an image capture mechanism instance corresponding to an image capture mechanism. It is determined whether the image capture mechanism is started, and if it is determined that the image capture mechanism is started, an image capture mechanism instance is generated. For example, an image capture mechanism instance is created based on a class corresponding to a camera, and the image capture mechanism instance is capable of capturing data information captured by a particular camera. Creating an image capture mechanism instance is: Camera camera = Camera.open(cameraId), where camera is the image capture mechanism instance.

[0039] There may be various approaches for binding the image capture means instance with the surface texture instance. It is determined whether the surface texture instance is generated, and if it is determined that the surface texture instance is generated, the surface texture instance is provided to the image capture means instance, and the image capture means instance is bound with the surface texture instance by taking the surface texture instance as a call parameter. For example, using camera.setPreviewTexture(mSurfaceTexture), the image capture means instance is bound with the surface texture instance, where the image capture means instance, camera, takes the surface texture instance mSurfaceTexture as a call parameter, so that binding of mSurfaceTexture with camera can be realized.

[0040] FIG. 2 is a schematic flow diagram of capturing image data in some embodiments according to the image data distribution method of the present disclosure. As shown in FIG. 2:

[0041] Step 201: creating an image capture callback interface in an image capture means instance, where the image capture callback interface is used to realize callback sending of image data and provide an image data sending method.

[0042] Step 202, providing an image capture callback interface to a surface texture instance.

[0043] Step 203, receiving the image data sent by the surface texture instance by executing a callback in the image data sending method by using the image capturer instance.

[0044] In some embodiments, an interface callback calls a method in which a reference to an object created by using a class of a certain interface can be assigned to an interface variable declared by that interface, so that the interface variable can invoke the interface implemented by the class. The purpose of the callback is to send data and keep the data updated synchronously. The interface callback method compatible with this disclosure may be any of the many existing interface callback methods, such as the JAVA interface callback method.

[0045] The image data send method may be a callback method, which is a method that is called by a method pointer. If a pointer (address, reference) of the image data send method is passed to a certain method of a surface texture instance through a formal parameter, the image data send method can be called when the surface texture instance calls the pointer passed to the method.

[0046] In some embodiments, a surface texture instance (SurfaceTexture) is created in the background through OpenGl ES, where SurfaceTexture may be an existing class or instance. After the camera is opened, the surface texture instance (SurfaceTexture) is bound to an image capturer instance (Camera) to begin previewing and processing the information captured by the camera. An image capture callback interface Camera.PreviewCallback is implemented and created in the image capturer instance, and an image data sending method is provided in Camera.PreviewCallback.

[0047] An image capture callback interface Camera.PreviewCallback is provided to the surface texture instance (SurfaceTexture) (this Camera.PreviewCallback is registered with the surface texture instance SurfaceTexture, an image data send method is provided in Camera.PreviewCallback, and a reference to the image data send method is sent to the surface texture instance).

[0048] When the surface texture instance (SurfaceTexture) determines that image data is available, it executes a callback in the image data sending method provided in Camera.PreviewCallback. The image capture means instance (Camera) receives the image data sent by the surface texture instance (SurfaceTexture) by executing a callback in the image data sending method provided in Camera.PreviewCallback.

[0049] FIG. 3 is a schematic flow diagram of image data distribution according to some embodiments of the image data distribution method of the present disclosure. As shown in FIG. 3:

[0050] Step 301, is to determine whether an image data delivery interface of an application and / or page instance is registered with an image capture means instance, where the image data delivery interface is used to realize callback delivery of image data and provide an image delivery method.

[0051] In some embodiments, an application and / or a page instance defines and creates an image data delivery interface that includes an image delivery method. To implement the image delivery method, the application and / or page instance registers the image data delivery interface and the image delivery method within the image capture instrument instance and sends a reference or address of the image data delivery interface and the image delivery method to the image capture instrument instance. Registering the image data delivery interface and sending the instance or address may be performed by using existing methods.

[0052] The image capturer instance calls back the registered image data delivery interface and image delivery method of the application and / or page instance under a trigger condition. The trigger condition may be that the image capturer instance receives image data sent by the surface texture instance by executing a callback in the image data send method.

[0053] Customized interface callback methods are registered for different functional pages or locations that require streaming data, and when the callback data is received by the Camera, it checks whether the registered interface exists, and if the registered interface exists, the data is fed back to the registered page via the interface.

[0054] Step 302, delivering image data to a corresponding application and / or page instance by an image capturer instance executing a callback on an image delivery method when an image data delivery interface of the application and / or page instance is registered with the image capturer instance.

[0055] In some embodiments, the applications include a video preview application, a face recognition application, a video recording application, a quick response (QR) code scanning application, etc., and the application and page instances receive image data delivered by the image capture means instance by performing a callback in the image data delivery method and perform processing based on the image data. For example, the video preview application performs video interface rendering based on the image data, the face recognition application inputs the image data to a face recognition software development kit (SDK) for processing and performs face recognition processing based on the processing result, the video recording application performs video recording based on the image data, and the QR code scanning application performs QR code recognition processing based on the image data.

[0056] FIG. 4 is a schematic flow chart of another embodiment of the image data distribution method of the present disclosure. As shown in FIG. 4:

[0057] Step 401: Initialize OpenGL ES settings.

[0058] Step 402, creating a texture instance.

[0059] Step 403, generating a surface texture instance by using the texture instance.

[0060] Step 404 , determining whether the camera is started, and if so, proceeding to step 407 , otherwise proceeding to step 405 .

[0061] Step 405, setting camera-related parameters and starting the camera.

[0062] Step 406 , determining whether a surface texture instance is to be generated, if so proceeding to step 407 , and if not proceeding to step 401 .

[0063] Step 407, binding an image capture mechanism instance with a surface texture instance.

[0064] Step 408, capturing image data in an interface callback manner by using an image capture means instance, and delivering the image data.

[0065] System background such as Android captures the video streaming data by binding SurfaceTexture with Camera, and the video streaming data is always present; when one or more functions of different pages need the video streaming data for certain functions, the video streaming data is returned through the registered interface by adapting the interface callback mechanism, so that multiple functions can be executed simultaneously.

[0066] For the video preview function, an Android system component surfaceView receives the video streaming data delivered by the image capture means instance and performs video interface rendering. For the face recognition function, the video streaming data delivered by the image capture means is sent to a different face recognition SDK, and after internal processing, the SDK compares the processing result with the face information already input to realize the face recognition function. For the recording function, by using an instance of the MediaCodec class provided by Android, the video streaming data delivered by the image capture means is received for recording.

[0067] In some embodiments, as shown in Fig. 5, the present disclosure provides an image data distribution device 50 applied to a terminal, which includes a texture instance generation module 51, a means instance generation module 52, an instance binding processing module 53, an image data generation module 54, and an image data distribution module 55. The texture instance generation module 51 generates a surface texture instance for processing information captured by an image capture means. The means instance generation module 52 generates an image capture means instance corresponding to the image capture means.

[0068] The instance binding processing module 53 binds the image capturer instance with the surface texture instance. The image data generation module 54 generates image data by the surface texture instance which processes the information input by the image capturer. The image data delivery module 55 retrieves the image data in an interface callback manner by using the image capturer instance, and delivers the image data to the application and / or page instance.

[0069] In some embodiments, the texture instance generation module 51 creates a texture instance by using OpenGL ES, and generates a surface texture instance by using the texture instance. The instrument instance generation module 52 determines whether an image capture instrument is initiated, and if it is determined that the image capture instrument is initiated, the instrument instance generation module 52 generates an image capture instrument instance.

[0070] The instance binding processing module 53 determines whether a surface texture instance is to be generated, and if it is determined that the surface texture instance is to be generated, the instance binding processing module 53 provides the surface texture instance to the image capture means instance, where the image capture means instance realizes binding with the surface texture instance by adopting the surface texture instance as a call parameter.

[0071] 6, the image data delivery module 55 includes an interface callback unit 551 and a callback delivery unit 552. The interface callback unit 551 creates an image capture callback interface in an image capture means instance, where the image capture callback interface is used to realize callback transmission of image data and provide an image data transmission method.

[0072] The interface callback unit 551 provides an image capture callback interface to the surface texture instance, and receives image data sent by the surface texture instance by executing a callback in the image data sending method by using the image capturer instance.

[0073] The callback delivery unit 552 determines whether the image data delivery interface of the application and / or page instance is registered with the image capture means instance, where the image data delivery interface is used to realize the callback delivery of image data and provide the image delivery method. If the image data delivery interface of the application and / or page instance is registered with the image capture means instance, the callback delivery unit 552 delivers the image data to the corresponding application and / or page instance by the image capture means instance that executes the callback in the image delivery method.
