[0023] It should be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchangeable with each other, and some of the steps can also be deleted.

[0024] At present, imaging systems composed of multiple cameras are widely used in various products, such as automobile driving assistance systems, which are mainly composed of cameras arranged at various positions of the car and on-board computers, and intelligent monitoring systems composed of multiple cameras and computers. Among them, the on-board computers and computers in the above-mentioned imaging systems are all equipped with hardware imaging interfaces, and are connected to the camera and the display module through the imaging interface to receive the video stream data of the camera and display it through the display module.

[0025] In the related art, when testing an image interface, a test camera or hardware device is generally connected to the image interface, and then the camera or related hardware device is run to verify whether the image interface is working properly. Therefore, the verification process of the image interface is relatively inefficient.

[0026] The present application provides an image interface verification method, system and image device for improving the efficiency of the image interface verification process.

[0027] Please refer to Figure 1 , Figure 1A schematic block diagram of an image interface verification system provided in an embodiment of the present application, wherein the image interface verification system 100 includes a storage module 110, a receiving module 120 and a sending module 130, the storage module 110 is respectively connected to the receiving module 120 and the sending module 130, the receiving module 120 is used to connect to the image output interface 201 of the device under test 200, and the sending module 130 is used to connect to the image input interface 202 of the device under test.

[0028] Next, combine Figure 1 This application introduces an image interface verification method. Please refer to Figure 2 , Figure 2 A flowchart of an image interface verification method provided in an embodiment of the present application specifically includes the following steps:

[0029] Step S21: Obtain at least one preset image from the storage module, and generate a serial data stream using the at least one preset image.

[0030] In the embodiment of the present application, the above-mentioned image interface verification system can be set in an electronic device, which is the device to be tested, and can be used to verify the image interface of the electronic device when the electronic device is started or receives an interface verification instruction. It can be understood that the image interface verification system also includes a controller, which can be a processor of the electronic device. When performing image interface verification, the processor of the electronic device runs an application to execute the image interface verification method provided by this solution.

[0031] Alternatively, the image interface verification system can also constitute an independent interface verification device, in which interfaces are respectively provided in the sending module and the receiving module for connecting with the image input interface and the image output interface of the device to be tested, and the interface verification device includes a controller and a memory, the memory stores the application, and the controller runs the application to execute the image interface verification method provided by this scheme.

[0032] Among them, the image input interface and image output interface of the device under test include but are not limited to HDMI interface (HDMI, High Definition Multimedia Interface), DVI interface (DVI, Digital Visual Interface) and VGA interface (VGA, Video Graphics Array), etc.

[0033] In the embodiment of the present application, various types of preset images may be pre-stored in the storage module, for example, images taken in different environments and under different photography-related devices, as well as network images transmitted by remote devices, etc., which are not limited here. After receiving the interface verification instruction, the controller may obtain at least one preset image from the storage module according to the interface verification instruction, and perform GMSL serial data processing (GMSL, Gigabit Multimedia Serial Link) to generate a serial data stream. For example, when it is necessary to test three image output interfaces at the same time, the interface verification instruction may be used to enable the controller to obtain three preset images for serial data processing, or for photography-related devices connected to the image input interface, the interface verification instruction may be used to enable the controller to obtain the preset image of the corresponding photography-related device for serial data processing, etc., which are not limited here.

[0034] Step S22: controlling the sending module to transmit the serial data stream to the image input interface.

[0035] In the embodiment of the present application, after the serial data stream is generated, the controller controls the sending module to obtain the serial data stream from the storage module, and transmits the serial data stream to the image input interface of the device under test. The device under test is in the startup state during the interface verification process, and after receiving the serial data stream through the image input interface, the serial data stream can be signal processed and finally output from the image output interface.

[0036] Step S23: Control the receiving module to obtain the returned serial data stream from the image output interface.

[0037] In the embodiment of the present application, when the controller controls the sending module to transmit the serial data stream, it will also control the receiving module to start and receive the serial data stream returned by the image output interface of the device under test. After starting, the receiving module can wait for a preset time before receiving the returned serial data stream to avoid misjudgment of interface verification caused by internal data transmission delay of the device under test.

[0038] Step S24: If the receiving module successfully obtains the returned serial data stream from the image output interface, it is determined that the image interface of the device under test is normal.

[0039] In the embodiment of the present application, when the receiving module successfully obtains the returned serial data stream from the image output interface, the controller can determine that the image interface of the device under test is normal, otherwise, it is determined that the image interface of the device under test is abnormal and the interface verification fails. The abnormal image interface of the device under test includes abnormal image input interface and abnormal image output interface.

[0040] Among them, in some embodiments, the image interface verification system is set in the device under test, and when the controller is the processor of the device under test, when it is determined that the image interface of the device under test is normal, the controller can control the device under test to start up and operate normally, and when the image interface is abnormal, the controller can control the device under test to display interface abnormality information after startup and stop working.

[0041] It can be understood that in the embodiment of the present application, by setting up an image interface verification system, including a storage module, a receiving module and a sending module, when verifying the image interface of the device to be tested, the pre-stored preset image is obtained from the storage module, and a serial data stream is generated and transmitted to the image input interface of the device to be tested, so that the image interface verification process does not need to plug the image interface into the test camera or hardware device, thereby improving the efficiency of the image interface verification process. In addition, serial data stream processing of the preset image can improve the stability and reliability of the preset image transmission process, thereby improving the stability and reliability of the verification process.

[0045] Step S33: Control the receiving module to obtain the returned serial data stream from the image output interface.

[0047] Step S34: controlling the receiving module to transmit the returned serial data stream to the storage module for storage.

[0048] In an embodiment of the present application, after determining that the receiving module receives a returned serial data stream from the image output interface, the controller will control the receiving module to transmit the serial data stream to the storage module for storage, so as to control the analysis of the stored serial data stream and obtain the verification result of the image interface of the device under test, so as to improve the reliability of the verification result.

[0049] Step S35: deserialize and play the serial data stream returned from the storage module.

[0050] Step S36: If the returned serial data stream is successfully deserialized and played, it is determined that the image interface of the device under test is normal.

[0051] In the embodiment of the present application, the storage module may also store a GMSL deserialization application, and the controller may run the application to deserialize the serial data stream returned from the storage module. After determining that the returned serial data stream is successfully deserialized, the controller determines that the image interface of the device under test is normal. Furthermore, the controller may also determine that when the deserialized image is consistent with the original preset image, the image interface of the device under test is normal, so as to further improve the reliability of the verification result.

[0059] In the embodiment of the present application, the computer interface unit is a CIM unit (CIM, computer interface module), and the image signal processing unit is an ISP unit (ISP, (Image Signal Processing, image signal processing).

[0060] In some embodiments, the receiving module includes a direct memory access unit, which is connected to the storage module and is also used to connect to the image output interface of the device under test.

[0062] Step S61: when a remote serial data stream sent by an external terminal is received through the receiving module, the multiplexing module is controlled to forward the remote serial data stream to the sending module.

[0063] In the embodiment of the present application, the external terminal includes an electronic device connected to the image interface verification system via remote communication, such as a computer, a tablet computer, etc. When the image interface verification system receives the remote serial data stream, it can directly use the remote serial data stream to verify the image interface.

[0064] Step S62: The sending module transmits the remote serial data stream to the image input interface.

[0065] In the embodiment of the present application, the controller controls the multiplexing module to forward the remote serial data stream to the sending module, and controls the sending module to transmit the remote serial data stream to the image input interface.

[0066] Step S63: Control the receiving module to obtain the remote serial data stream returned from the image output interface, and transmit it to the storage module for storage.

[0068] Step S65: If the returned serial data stream is successfully deserialized and played, it is determined that the image interface of the device under test is normal.

[0069] In the embodiment of the present application, the process of verifying the image interface using a remote serial data stream is similar to the process of verifying the image interface using a serial data stream generated by a preset image, and will not be repeated here.
