Referring to fig. 1, fig. 1 is a schematic structural diagram of a video processing platform according to an embodiment of the present disclosure.
As shown in fig. 1, the video processing platform 100 includes: a processing unit 11 and any at least two of the following interfaces: a Universal Serial Bus (USB) Interface 12, a video Serial Display Link (FPDlink) Interface 13, and a Mobile Industry Processor Interface (MIPI) Interface 14.
By way of example and not limitation, fig. 1 exemplarily illustrates a case where the video processing platform 100 includes the USB interface 12, the FPDlink interface 13, and the MIPI14 at the same time. USB interface 12, FPDlink interface 13, and/or MIPI14 communicate with processing unit 11.
In a specific application, the USB interface 12 may be connected to a video capture device having a USB interface to receive a video signal transmitted by the video capture device and transmit the video signal to the processing unit 11. By way of example and not limitation, the video capture device with the USB interface may be a binocular camera device, based on which the video capture device with the USB interface may transmit a video signal including depth information to the USB interface 12, and may also transmit a video signal not including depth information to the USB interface 12.
The FPDlink interface 13 may be connected to a video capture device having the FPDlink interface, so as to receive a video signal transmitted by the video capture device and transmit the video signal to the processing unit 11. The FPDlink interface 13 typically supports video input for mid-range (e.g., within 2 meters) camera acquisition devices.
In a specific application, in order to ensure the video transmission frame rate of the video acquisition device with the FPDlink interface, the video acquisition device with the FPDlink interface may be connected to the FPDlink interface 13 through a coaxial cable, so that the mode of accessing the video acquisition device with the FPDlink interface to the video processing platform 100 may be simplified, and the video transmission frame rate of the video acquisition device with the FPDlink interface may be increased.
The MIPI14 may be connected to a video capture device having a MIPI to receive a video signal transmitted by the video capture device and transmit the video signal to the processing unit 11. MIPI14 generally supports short-range (e.g., within 30 centimeters) camera capture of video input by a device. Since the video acquisition device with the MIPI can directly transmit the video signal to the video processing platform 100 through the MIPI14, the video processing platform 100 supports video input with high resolution and high frame rate, and the cost can be reduced.
In a particular application, the video capture device may be, by way of example and not limitation, a camera. The camera with the USB interface, the FPDlink interface or the MIPI can be arranged in the same terminal device or different terminal devices. Illustratively, the terminal device may be a robot or a monitor, etc.
The Processing Unit 11 may be an image Processing Unit (GPU), or may be other types of processors, and is not limited herein.
It can be seen from the above that, because the video processing platform provided in the embodiment of the present application includes multiple different types of video interfaces, the video processing platform can receive video signals transmitted by terminal devices having different video interfaces, thereby improving the multiplexing rate of the video processing platform, and reducing the development cost and maintenance cost of the video processing platform.
In the embodiment of the present application, the number of USB interfaces 12, the number of FPDlink interfaces 13, and/or the number of MIPI14 may be one or more.
For convenience of understanding, fig. 2 illustrates that the number of USB interfaces 12, the number of FPDlink13, and the number of MIPIs 3, and a video processing platform provided in another embodiment of the present application is described in detail.
As shown in fig. 2, in this embodiment, when the number of the USB interfaces 12 is multiple, the video processing platform 100 further includes a USB hub 15, and the multiple USB interfaces 12 can communicate with the processing unit 11 through the USB hub 15.
In this embodiment, the processing unit 11 may include at least one USB interface 111 (only one is shown in the figure), and the at least one USB interface 111 is connected to the USB hub 15. Each USB interface 12 may transmit video signals to the USB interface 111 of the processing unit 11 through the USB hub 15. The processing unit 11 can also transmit control signals to each USB interface 12 through its USB interface 111, and further transmit control signals to the video capture device having the USB interface.
In another embodiment of the present application, when the number of the FPDlink interfaces 13 is plural, the video processing platform 100 further includes a serial deserializing unit 16, and the plurality of FPDlink interfaces 13 communicate with the processing unit 11 through the serial deserializing unit 16. Specifically, the deserializing unit 16 may deserialize the multiple video signals from the multiple FPDlink interfaces 13 into one video signal, and transmit the one video signal to the processing unit 11; or the deserializing unit 16 may decompose one video signal output by the processing unit 11 into multiple video signals and transmit one video signal to each FPDlink interface 13.
In this embodiment, the processing unit 11 may further include one or more camera serial interfaces (CMOS Sensor interfaces, CSI) 112. The one or more CSIs are coupled to a serdes unit 16, and the FPDlink interface 13 may transmit video signals to the CSI112 via the serdes unit 16.
In another embodiment of the present application, each MIPI14 may be connected with one CSI13 of processing unit 11, and MIPI14 may transmit video signals directly to CSI13 of processing unit 11.
In yet another embodiment of the present application, the processing unit 11 further comprises a synchronization signal transmission interface 113. The synchronization signal transmission interface 113 is configured to transmit a synchronization signal to the USB interface 12, the FPDlink interface 13, and the MIPI14, where the synchronization signal is used for the USB interface 12, the FPDlink interface 13, and the MIPI14 to synchronously receive video signals, so that the video processing platform 100 can synchronously acquire videos from different types of video interfaces.
In a particular application, the synchronization signal transmission interface 113 may be, by way of example and not limitation, a General-purpose input/output (GPIO) interface.
In yet another embodiment of the present application, the processing unit 11 further comprises a control signal transmission interface 114. The control signal transmission interface 114 is used for transmitting a control signal to the USB interface 12, the FPDlink interface 13, and the MIPI14, so that the control of the video capture device connected to the video processing platform 100 can be realized.
In particular applications, the control signal transmission interface 14 may be, by way of example and not limitation, an Inter Integrated Circuit (I2C) interface.
