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, a plurality of first output interfaces 12, a first conversion unit 13 and at least two second conversion units 14. An input of the first conversion unit 13 is connected to the first input interface 11. The output of the first conversion unit 13 is connected to the input of each second conversion unit 14. The output of each second conversion unit 14 is connected to each first output interface 12. The first input interface 11 is configured to receive a first video signal collected by the image collecting device. The first conversion unit 13 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 each of the second conversion units 14 is configured to convert each path of the first video signal sent by the first conversion unit 13 into multiple paths of the first video signals, respectively. Each first output interface 12 is configured to send each first video signal to each vehicle controller.

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

In this embodiment, the first video module 10 is provided with the first converting unit 13 and the second converting unit 14 which are cascaded, so that one path of received first video signal can be converted into multiple paths of same first video signals, and each first video signal is sent to a corresponding vehicle controller. Therefore, the technical effect that a plurality of vehicle controllers can share the same video data sent by the same image acquisition device can be realized 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, the second video module 20 is provided with the third conversion unit 23, so when the vehicle controller needs to simultaneously utilize data acquired by a plurality of 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 third conversion unit 23 and sent to the corresponding vehicle controller, thereby saving the time for the vehicle controller to respectively request different image acquisition devices to acquire the video data, effectively saving the number of interfaces and wiring harnesses on the vehicle controller, and optimizing the arrangement space in the vehicle.

In one example, the vehicle controller connected to the second output interface 22 may be the vehicle controller connected to any of the first output interfaces 12. That is, the vehicle controller may simultaneously receive the video signals transmitted by the first video module 10 and the second video module 20.

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

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, the first video module 10 has a plurality of first input interfaces 11, each first input interface 11 being usable for connecting an image capture device arranged at a different location on the vehicle. Each first input interface 11 is connected to a first conversion unit 13, and each first conversion unit 13 converts one path of first video signals input by the corresponding first input interface 11 into multiple paths of first video signals and sends the multiple paths of first video signals to the second conversion unit 14. Through the technical scheme of the embodiment, the first video signals sent by the plurality of image acquisition devices can be subjected to incremental conversion, so that the first video signals sent by each image acquisition device can be converted into multiple paths of first video signals. It should be noted that, since the positions of the image capturing devices installed on the vehicle are different, the information data included in the first video signal transmitted by each image capturing device is different.

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, 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 13, the first input interface 11, the first output interface 12, the second conversion unit 14, the third 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 13 includes a first deserializer 131 and a plurality of first serializers 132.

The output end of each first serializer 132 is connected to each first output interface 12. The first deserializer 131 is configured to parse and convert the first video signal into multiple parallel first video signals, and then send each first video signal to each first serializer 132. The first serializer 132 is configured to convert the received first video signal into a serial signal and transmit the serial signal to a corresponding vehicle controller. Through the connection of the first deserializer 131 and the plurality of first serializers 132, 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 requirements of different vehicle controllers on the acquisition of video data of the image acquisition device can be met.

In one example, the first deserializer 131 and the first serializer 132 may be electrically connected with the micro control unit 30, and the micro control unit 30 may initialize the first deserializer 131 and the first serializer 132 and may also control the operation states of the first deserializer 131 and the first serializer 132.

In a specific application example, the video captured by the image capturing device is transmitted to the first deserializer 131 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 131 transmits the first video signal to the plurality of first serializers 132, respectively, in the form of a multi-path mipi (mobile Industry processor interface) signal or rgb (red Green blue) signal. Each first serializer 132 outputs the first video signal to the corresponding first output interface 12 through the coaxial cable or the differential LVDS. The first deserializer 131 and each first serializer 132 are electrically connected to a micro control Unit 30 (MCU), the micro control Unit 30 may initialize the first deserializer 131 and each first serializer 132 through an Inter-Integrated Circuit (IIC) or Serial Peripheral Interface (SPI), and may control an Interface corresponding to the first serializer 132 or the first deserializer 131 to be opened or closed based on different device addresses of the first deserializer 131 and each first serializer 132.

In one embodiment, as shown in fig. 3, the second conversion unit 14 includes a plurality of second deserializers 141 and a plurality of second serializers 142. The input terminal of each second deserializer 141 is connected to the output terminal of each first serializer 132, respectively. The output terminal of each second deserializer 141 is connected to the input terminals of the plurality of second serializers 142, respectively. The output end of each second serializer 142 is connected to each first output interface 12. In this embodiment, by cascading the first deserializer 131, the first serializer 132, the second deserializer 141, and the second serializer 142, one path of the first video signal can be converted into more paths of the first video signal, so as to meet the video data acquisition requirement of more vehicle controllers for the image capture device.

In a specific application example, the video captured by the image capturing device is transmitted to the first deserializer 131 through the first input interface 11 via the coaxial cable or the differential LVDS as a first video signal. The first deserializer 131 transmits the first video signals to the plurality of first serializers 132, respectively, in the form of a plurality of MIPI signals or RGB signals. Each first serializer 132 transmits the first video signal to each second deserializer 141 through a coaxial cable or a differential LVDS, respectively. Each of the second deserializers 141 transmits the first video signal to the plurality of second serializers 142 through the multi-path MIPI signal or RGB signal, respectively. Each of the second serializers 142 outputs the first video signal to the corresponding first output interface 12 via the coaxial cable or the differential LVDS. The micro control unit 30 is further electrically connected to the second deserializer 141 and each second serializer 142, the micro control unit 30 may initialize the first deserializer 131, each first serializer 132, the second deserializer 141, and each second serializer 142 through IIC or SPI, and may further control the opening and closing of the corresponding interfaces of the first serializer 132, the first deserializer 131, the second serializer 142, or the second deserializer 141 based on different device addresses of the first deserializer 131, each first serializer 132, each second deserializer 141, and each second serializer 142.

In one embodiment, as shown in fig. 4, the third conversion unit 23 includes a third deserializer 231 and a third serializer 232. The input of the third deserializer 231 is connected to each second input interface 21. An input end of the third serializer 232 is connected to an output end of the third deserializer 231, and an output end of the third serializer 232 is connected to the second output interface 22. The third deserializer 231 is configured to parse and convert the received multiple paths of second video signals into one path of third video signal, and then send the third video signal 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 third conversion unit 23 receives the second video signal a, the second video signal b, and the second video signal c respectively transmitted by three image capturing apparatuses. The received three paths of second video signals are converted into one path of third video signals through 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 a, the second video signal b, and the second video signal c.

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. The third serializer 232 outputs the third video signal to the corresponding second output interface 22 through the coaxial cable or the differential LVDS. The third deserializer 231 and the third serializer 232 are electrically connected to the micro control unit 30, and the micro control unit 30 may initialize the third deserializer 231 and the third serializer 232 through IIC or SPI, and may control an interface corresponding to the third deserializer 231 or the third serializer 232 to be opened or closed based on different device addresses of the third deserializer 231 and the third serializer 232.

In one embodiment, as shown in fig. 5, the third conversion unit 23 includes a plurality of third deserializers 231, a plurality of third serializers 232, one fourth deserializer 233, and one fourth serializer 234. The input terminal of each third deserializer 231 is connected to a plurality of second input interfaces 21, respectively. The input terminal of each third serializer 232 is connected to the output terminal of each third deserializer 231. The output terminal of each third serializer 232 is connected to the input terminal of the same fourth deserializer 233. An output terminal of the fourth deserializer 233 is connected to an input terminal of the fourth serializer 234. An output of the fourth serializer 234 is connected to the second output interface 22. When there are a lot of second video signals 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 then a fourth deserializer 233 may be used to fuse the video signals fused by the third deserializers 231 again to obtain third video signals.

In one example, the third conversion unit 23 includes two third deserializers 231, two third serializers 232, one fourth deserializer 233, and one fourth serializer 234. A third deserializer 231 receives the second video signal a and the second video signal b sent by the two image capturing devices, and converts the two video signals into a video signal e. The other third deserializer 231 receives the second video signal c and the second video signal d sent by the two image capturing devices, and converts the second video signal c and the second video signal d into a video signal f. The fourth deserializer 233 receives the video signal e composed of the second video signal a and the second video signal b sent by one third serializer 232, and the fourth deserializer 233 also receives the video signal f composed of the second video signal c and the second video signal d sent by the other third serializer 232.

The third video signal includes data information of a second video signal a, a second video signal b, a second video signal c, and a second video signal d.

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. Each third deserializer 231 transmits each video signal, which is a combination of each second video signal, to each third serializer 232 in the form of an MIPI signal or an RGB signal. Each third serializer 232 transmits each video signal to the fourth deserializer 233 through the coaxial cable or the differential LVDS. The fourth deserializer 233 outputs the third video signal formed by the combination of the respective video signals to the corresponding second output interface through the coaxial cable or the differential LVDS. The fourth deserializer 233 and the fourth serializer 234 are electrically connected to the micro control unit 30, and the micro control unit 30 may initialize the fourth deserializer 233 and the fourth serializer 234 through IIC or SPI, and may further control an interface corresponding to the fourth deserializer 233 or the fourth serializer 234 to be opened or closed based on different device addresses of the fourth deserializer 233 and the fourth serializer 234.

In one example, the number of the third deserializers 231 and the number of the third serializers 232 may be kept the same. The number of the fourth deserializers 233 and the number of the fourth serializers 234 may be kept the same.

The output end of the sixth serializer 542 is connected to the third output interface 52. When there are many fourth video signals to be fused, in order to increase the processing speed of the video signals, a plurality of fifth deserializers 531 may be used to fuse a part of the fourth video signals respectively to obtain multiple paths of fifth video signals, and then a sixth deserializer 541 may be used to fuse the fifth video signals fused by the fifth deserializers 531 again to obtain a sixth video signal.

In this embodiment, when the vehicle controller needs to simultaneously utilize data acquired by a plurality of image acquisition devices on the vehicle, the fourth conversion unit 53 and the fifth conversion unit 54 can merge video data acquired by the image acquisition devices located at different positions on the vehicle and send the merged video data to the corresponding vehicle controller, so that the time that the vehicle controller needs to respectively request different image acquisition devices to acquire the video data is saved, the number of interfaces and the number of wire harnesses on the vehicle controller are saved, and the arrangement space in the vehicle is optimized.

In a specific application example, the video captured by each image capturing device is respectively transmitted to each fifth deserializer 531 through each third input interface 51 via a coaxial cable or a differential LVDS in the form of a fourth video signal.

Each fifth serializer 532 transmits each fifth video signal to the sixth deserializer 541 through the coaxial cable or the differential LVDS. The sixth deserializer 541 outputs a sixth video signal formed by combining the respective fifth video signals to the corresponding third output interface 52 through the coaxial cable or the differential LVDS.
