Description

Technical Field

[0001] This application relates to the field of vehicle-mounted cameras, and in particular to a configuration method, device, equipment and medium for a multi-channel camera applied to vehicles. Background Art

[0002] When configuring multi-channel cameras in vehicles, it is necessary to define in advance the number of cameras to be connected and the connection positions. Then, according to the number of cameras and connection positions defined in advance, set the corresponding ID values and pass them to the camera image sensor (camera sensor) driver for configuration operations, and create a fixed Lua file to encode the information of the cameras that need to be configured. In the existing configuration method, the ID values need to be configured in advance. Every time the number of cameras to be connected or the connection positions are changed, the ID values must be recalculated, and then the program needs to be modified to change the ID values, modify the camera configuration file and the camera feature configuration file (Lua file), and reconfigure the encoded camera information, which is cumbersome and inconvenient. In addition, in the existing configuration method, during the use of multi-channel cameras, when one camera has an abnormality, the ID values do not match the actual camera situation, and the Lua file does not match the actual camera situation, resulting in all cameras being unusable, and it is very difficult to determine which camera has an abnormality, greatly increasing the workload of the debugging process and subsequent after-sales service.

[0049] The embodiments of the present application provide a flexible configuration method for multiple cameras applied to vehicles.

[0050] As Figure 1 and Figure 2 shown, a flexible configuration method for multiple cameras applied to vehicles includes the following steps:

[0051] According to different grouping situations of multiple in-vehicle cameras, a camera feature configuration file is generated for each grouping situation, and several camera feature configuration files are obtained. Among them, the camera feature configuration file includes relevant configuration parameters for configuring each camera in the corresponding grouping situation.

[0052] According to the current grouping situation of multiple cameras, detect the number of cameras in each camera group and the position information of each camera, and form a camera channel information file.

[0053] Parse out the id value required for installing the driver according to the camera channel information file, and install the corresponding driver program for each camera according to the id value.

[0054] Call the camera data stream encoding component according to the camera channel information file, and encode the information of each camera through the camera data stream encoding component; among them, when the camera data stream encoding component encodes, it needs to know some feature information of the camera, so the special diagnosis information of each camera is parsed out through the valid camera channel information file (valid_chan) for camera data stream encoding, and the special diagnosis information is, for example, the resolution of the camera.

[0055] According to the camera channel information file, determine the camera feature configuration file corresponding to the current grouping situation of multiple cameras from several camera feature configuration files, and configure the relevant parameters of each camera according to the determined camera feature configuration file.

[0056] This application is based on Ambarella cv2, and a set of programs can be compatible with multiple combinations of multiple cameras on the program, which improves the software flexibility. During the debugging stage, production stage, and after-sales stage, it can quickly locate whether multiple cameras are working properly. If there is an abnormality, it can be known which channel camera has an abnormality by observing the image, which greatly improves the debugging efficiency.

[0057] Especially in the after-sales stage, due to the particularity of the vehicle-mounted industry, it is difficult to remove and detect abnormal vehicle-mounted cameras after mass production. As Figure 1 shown, taking 7-channel cameras as an example, the 7-channel cameras are divided into three groups. The data of the 7-channel cameras passes through the corresponding serializer (ser0-7). The 7 serializers are divided into three groups and respectively correspond to three deserializers (der0-3). The data of the three deserializers goes into the Ambarella cv2 system. The current Ambarella solution is that if one channel camera has an abnormality, all 7-channel cameras are abnormal. If there is a camera abnormality, it is necessary to remove the 7-channel cameras on the vehicle, and the workload is quite large. After adopting the flexible camera configuration method of this solution, it can accurately locate which channels and which positions of the cameras have abnormalities, and can accurately replace the abnormal cameras, which greatly improves the work efficiency.

[0058] AsFigure 3 As shown, in one embodiment, taking 7-channel cameras and two types of cameras as an example, a camera feature configuration file (Lua file) for each possible multi-channel camera situation enumerated is created, with a total of 17 Lua files.

[0059] In one embodiment, according to the number of camera groups included in the current grouping situation of the multi-channel cameras, the corresponding number of multi-channel camera detection programs des0-detect.sh, des1-detect.sh, des2-detect.sh,... are generated. One multi-channel camera detection program is used to detect the number of cameras and the position of each camera in a camera group, and a camera channel information file (valid_chanx) is output. The camera channel information file contains camera information (number and position); several multi-channel camera detection programs output multiple valid camera channel information files, such as: valid_chan0, valid_chan1, valid_chan2,....

[0060] To detect the position of each camera in a camera group through one multi-channel camera detection program, it includes: the camera detection program initializes the power supply of each camera's image sensor, and obtains the camera channel information of each camera by checking the connection lock status (linklock status) of the deserializer (des) connected to each camera. The camera detection program de-initializes the power supply of each camera's image sensor.

[0061] In one embodiment, multiple camera channel information files are spliced into a combined camera channel information file. A master control program is made to call the valid_chan splicing component to splice valid_chan0, valid_chan1, valid_chan2 into a valid combined camera channel information file. The id value required for installing the driver is parsed from the valid combined camera channel information file, and the corresponding driver program is installed for each camera according to the id value; the camera data stream encoding component is called according to the data in the valid combined camera channel information file, and the information of each camera is encoded through the camera data stream encoding component; according to the combined camera channel information file, the camera feature configuration file corresponding to the current grouping situation of the multiple cameras is determined from several camera feature configuration files, and the relevant parameters of each camera are configured according to the determined camera feature configuration file. Merging multiple camera channel information files into one file reduces the number of inputs in the subsequent usage process, reduces the input volume of the process of parsing the id value required for installing the driver, the process of calling the camera data stream encoding component to automatically configure the camera information to be encoded and perform encoding, and the process of obtaining the correct camera feature configuration file name, and improves the operation speed.

[0062] In one embodiment, parsing the id value required for installing the driver from the camera channel information file includes: parsing the id value required for installing the driver from the camera channel information file through the id parsing component, and then the camera image sensor driver installation component installs the corresponding driver program.

[0063] In one embodiment, determining the camera feature configuration file corresponding to the current grouping situation of the multiple cameras from several camera feature configuration files according to the camera channel information file includes: generating a program (getluaname.sh) for obtaining the camera feature configuration file. The program for obtaining the camera feature configuration file takes the camera channel information file (valid_chan) as input and outputs the name (lua_file_name) of the camera feature configuration file corresponding to the current grouping situation of the multiple cameras; the camera feature configuration file corresponding to the current grouping situation of the multiple cameras is read according to the name.

[0064] Specifically, the total control program uses the valid camera channel information file (valid_chan) as a parameter to call getluaname.sh to obtain the correct lua file name, and then calls the lua file configuration component to obtain the correct lua file and configure this lua file. getluaname.sh matches the correct lua file through the valid camera channel information file (valid_chan) for the lua file configuration component to perform correct camera configuration.

[0065] In this embodiment, a computer device is provided, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the above-mentioned arbitrary data storage method is implemented.

[0066] Specifically, the computer device can be a computer terminal, a server, or a similar computing device.

[0067] In this embodiment, a computer-readable storage medium is provided, and the computer-readable storage medium stores a computer program for executing the above-mentioned arbitrary data storage method.

[0068] Specifically, the computer-readable storage medium includes permanent and non-permanent, removable and non-removable media, and information storage can be implemented by any method or technology.
