Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the embodiments of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Fig. 1 shows a block diagram of a video processing apparatus according to an embodiment of the present application. As shown in fig. 1, the video processing apparatus includes at least a first video module 10 and a second video module 20.

The first video module 10 has at least one first input interface 11 and a first conversion unit 12. The input end of the first conversion unit 12 is connected to the first input interface 11, and the first input interface 11 is configured to receive a first video signal collected by the image collecting device. The first conversion unit 12 is configured to convert one path of the first video signal sent by the first input interface 11 into multiple paths of the first video signals, and transmit the multiple paths of the first video signals to corresponding interfaces through an output end of the first conversion unit 12.

The second video module 20 has a plurality of second input interfaces 21, a second output interface 22, and a second conversion unit 23. The input of the second conversion unit 23 is connected to the second input interfaces 21 and the output of the first conversion unit 12, and the second output interface 22 is connected to the output of the second conversion unit 23. Each second input interface 21 is used for receiving a second video signal sent by each image capturing device. The second converting unit 23 is configured to convert multiple paths of second video signals and/or the first video signal into a path of third video signal, and the second output interface 22 is configured to send the third video signal to the vehicle controller.

In this embodiment, the first video module 10 can convert one path of received first video signals into multiple paths of first video signals containing the same data information through the first conversion unit 12, and can send each first video signal to a corresponding vehicle controller through the second output interface 22. Therefore, the technical effect that a plurality of vehicle controllers share the same video data sent by the same image acquisition device can be achieved by arranging the first video module 10. And the technical effects of reducing the arrangement number of the image acquisition devices on the vehicle and reducing the production and manufacturing cost of the vehicle are further achieved. The technical problem that when different types of vehicle controllers acquire video data of the same vehicle visual angle in the prior art, an image acquisition device needs to be arranged for each vehicle controller is effectively solved. Meanwhile, since the second conversion unit of the second video module 20 can convert multiple paths of second video signals into one path of third video signals and convert multiple paths of second video signals and multiple paths of first video signals into one path of third video signals, when the vehicle controller needs to simultaneously utilize data acquired by multiple image acquisition devices on the vehicle, the video data acquired by the image acquisition devices located at different positions on the vehicle can be merged through the second conversion unit and sent to the corresponding vehicle controller, so that the time for the vehicle controller to respectively request different image acquisition devices to acquire the video data is saved, meanwhile, the number of interfaces and wiring harnesses on the vehicle controller can be effectively saved, and the arrangement space in the vehicle is optimized.

In one example, the output end of the first conversion unit 12 transmits the first video signal to the corresponding interface, which may be understood as transmitting the first video signal to the input interface, the output interface or other interface connected to the vehicle controller of each video module in the embodiments of the present application through the output end of the first conversion unit 12.

In one example, the second output interface 22 is plural, and each of the second output interfaces 22 is connected to an output terminal of the first conversion unit 12 and an output terminal of the second conversion unit 23. So that a plurality of first video signals containing the same data information after being incrementally converted by the first conversion unit 12 can be transmitted to different vehicle controllers through the respective second output interfaces 22. And enables the third video signals combined by the second conversion unit 23 to be transmitted to different vehicle controllers through the respective second output interfaces 22.

In one example, the second video signals input by the second input interfaces 21 contain different data information.

In one example, when the first conversion unit 12 and the plurality of first input interfaces 11 are connected, each first input interface 11 may be used to connect image capturing devices disposed at different positions on the vehicle. The data information contained in the first video signal input into the corresponding first input interface 11 by each image capturing device is different. The first conversion unit 12 may convert each received first video signal into multiple first video signals containing the same data information, thereby implementing incremental conversion of one first video signal sent by each image capture device, and implementing sending each converted first video signal containing the same data information to the corresponding multiple vehicle controllers, so that each vehicle controller can perform resource sharing on the video signals captured by the same image capture device. The first conversion unit 12 may further send the converted multiple paths of first video signals containing different data information to the second conversion unit 23, so that the second conversion unit 23 converts each first video signal containing different data information into one path of third video signal, or the second conversion unit 23 converts at least one path of first video signal and at least one path of second video signal into one path of third video signal.

In one example, the image capture device may employ any capture device known in the art, such as any type of camera known in the art. Each of the image capturing devices connected to the second video module 20 may include an image capturing device connected to the first video module 10.

In one example, a vehicle controller may be understood as any device on a vehicle that requires computational processing using image or video data. Each vehicle controller that receives the video signal may include an ADAS (Advanced driving assistance System) controller, an intelligent headlight controller, a drive recorder controller, a streaming media rearview mirror controller, and the like, which are not particularly limited herein.

In one example, as shown in fig. 1, the video processing apparatus may further include a micro control unit 30. The micro control unit 30 is electrically connected to the first video module 10 and/or the second video module 20. The micro control unit 30 is used for controlling the actions of each device in the first video module 10 and the second video module 20. For example, the first conversion unit 12, the first input interface 11, the first output interface, the second conversion unit 23, the second input interface 21, and the second output interface 22 may be controlled, configured, and initialized.

In one example, as shown in fig. 1, the video processing apparatus may further include a power supply module 40, and the power supply module 40 is configured to supply power to various components of the video processing apparatus.

In one embodiment, as shown in fig. 2, the first conversion unit 12 includes a first deserializer 121 and a plurality of first serializers 122. An input terminal of the first deserializer 121 is connected to the first input interface 11, an input terminal of each first serializer 122 is connected to an output terminal of the first deserializer 121, and an output terminal of each first serializer 122 is connected to an input terminal of the second converting unit 23 and/or the second output interface 22.

The first serializer 122 is configured to convert the received first video signal into a serial signal and send the serial signal to the second conversion unit 23 or send the serial signal to a corresponding vehicle controller through the second output interface 22. Through the connection of the first deserializer 121 and the plurality of first serializers 122, one path of first video signals sent by the image acquisition device can be converted into multiple paths of first video signals, so that the requirement of different vehicle controllers for acquiring video data acquired by the same image acquisition device is met.

In one example, the first deserializer 121 and the first serializer 122 may be electrically connected with the micro control unit 30, and the micro control unit 30 may initialize the first deserializer 121 and the first serializer 122 and may also control the operation states of the first deserializer 121 and the first serializer 122.

In a specific application example, the video captured by the image capturing device is transmitted to the first deserializer 121 through the first input interface 11 via a coaxial cable or a Differential LVDS (Low-Voltage Differential Signaling) as a first video signal. The first deserializer 121 transmits the first video signal to the plurality of first serializers 122, respectively, in the form of a multi-path mipi (mobile Industry processor interface) signal or rgb (red Green blue) signal. Each first serializer 122 outputs the first video signal to the second output interface 22 or the second conversion unit 23 through the coaxial cable or the differential LVDS, respectively. The first deserializer 121 and each first serializer 122 are electrically connected to a micro control Unit 30 (MCU), the micro control Unit 30 may initialize the first deserializer 121 and each first serializer 122 through an Inter-Integrated Circuit (IIC) or Serial Peripheral Interface (SPI), and may control an Interface corresponding to the first serializer 122 or the first deserializer 121 to be opened or closed based on different device addresses of the first deserializer 121 and each first serializer 122.

In one embodiment, as shown in fig. 3, the first converting unit 12 further includes a plurality of second deserializers 123, an input terminal of each second deserializer 123 is connected to an output terminal of each first serializer 122, an output terminal of each second deserializer 123 is further connected to a plurality of second serializers 124, and an output terminal of each second serializer 124 is connected to an input terminal of the second converting unit 23 and/or the second output interface 22.

In this embodiment, a first deserializer 121, a first serializer 122, a second deserializer 123 and a second serializer 124 are cascaded, so that one path of first video signal can be converted into more paths of first video signals, and the video data acquisition requirements of more vehicle controllers on the image capture device can be met.

In a specific application example, the video captured by the image capturing device is transmitted to the first deserializer 121 through the first input interface 11 via the coaxial cable or the differential LVDS as a first video signal. The first deserializer 121 transmits the first video signals to the plurality of first serializers 122, respectively, in the form of a plurality of MIPI signals or RGB signals. Each first serializer 122 transmits the first video signal to each second deserializer 123 and the second output interface 22 through a coaxial cable or differential LVDS, respectively. Each of the second deserializers 123 transmits the first video signal to the plurality of second serializers 124 through the multi-path MIPI signal or RGB signal, respectively. Each of the second serializers 124 outputs the first video signal to the corresponding second output interface 22 and/or second conversion unit 23 via the coaxial cable or the differential LVDS. The micro control unit 30 is further electrically connected to the second deserializer 123 and each second serializer 124, and the micro control unit 30 may initialize the first deserializer 121, each first serializer 122, the second deserializer 123, and each second serializer 124 through IIC or SPI, and may further control the opening and closing of the corresponding interfaces of the first serializer 122, the first deserializer 121, the second serializer 124, or the second deserializer 123 based on different device addresses of the first deserializer 121, each first serializer 122, each second deserializer 123, and each second serializer 124.

The third deserializer 231 is configured to parse and convert the received multiple paths of second video signals into one path of third video signals, or parse and convert the received second video signals and the received first video signals into one path of third video signals, or parse and convert the received multiple paths of first video signals containing different data information into one path of third video signals, and then send the third video signals to the third serializer 232. The third serializer 232 is configured to convert the received third video signal into a serial signal and transmit the serial signal to the vehicle controller.

In one example, the third deserializer 231 and the third serializer 232 may be electrically connected with the micro control unit 30, and the micro control unit 30 may initialize the third deserializer 231 and the third serializer 232 and may also control the operation state of the third deserializer 231 and the third serializer 232.

In one example, the second conversion unit 23 receives the second video signal a, the second video signal b, and the second video signal c respectively transmitted by the three image capturing apparatuses.

In another example, the second conversion unit 23 receives the second video signal transmitted by the image capture device and the first video signal transmitted by the first conversion unit 12. The received first video signal and second video signal are converted into a path of third video signal by the conversion of the internal third deserializer 231 and the internal third serializer 232. The third video signal includes all data information of the second video signal and the first video signal.

In a specific application example, the video captured by each image capturing device is respectively transmitted to the third deserializer 231 through each second input interface 21 via the coaxial cable or the differential LVDS in the form of a second video signal. The third deserializer 231 transmits the third video signal, which is a combination of the respective second video signals, to the third serializer 232 in the form of an MIPI signal or an RGB signal.

When there are a lot of second video signals and/or first video signals that need to be fused, in order to increase the processing speed of the video signals, a plurality of third deserializers 231 may be used to fuse a part of the second video signals and/or first video signals, and then a fourth deserializer is used to fuse the video signals fused by the third deserializers 231 again to obtain third video signals.

In a specific application example, the video captured by each image capturing device is respectively transmitted to each third deserializer 231 through each second input interface 21 via the coaxial cable or the differential LVDS in the form of a second video signal.
