Description
Technical Field
The present disclosure relates to the field of automotive vision control technologies, and in particular, to a method, an apparatus, a device, and a readable storage medium for controlling camera power-on initialization.
Background
Along with the progress of society, the development of science and technology and the improvement of economic living standard, the development of automobiles is more and more perfect, and because the automobile can save time and improve the working efficiency, the automobile gradually becomes an indispensable necessity in life, and simultaneously, because the requirement of people on the automobile is more and more high, the automobile is not a simple transportation tool any more, and is a life style expression. However, as automobiles become necessary transportation tools for families, people have more and more problems due to more and more vehicles on roads while bringing convenience to life, such as traffic jams, traffic accidents, environmental pollution, waste of a large amount of energy and the like. The driving safety of automobiles has attracted extensive attention of people due to frequent traffic accidents, for example, when backing a car, the traffic accidents caused by backing a car frequently occur due to the existence of a vision blind area, and a great hidden danger is brought to traffic safety.
With the rapid development of images, computer vision technologies and intelligent driving technologies, more and more technologies are applied to the automotive electronics field, for example, cameras are widely applied to vehicles to reduce the possibility of the traffic safety accidents. For example, a real-time image of a vehicle-mounted rear-view camera is displayed based on a reversing image system, so that a driver is intuitively prompted about the environment condition behind the vehicle, and convenience is brought to parking and reversing. However, since the conventional image-based car backing image system is only provided with the camera at the tail of the car, the conventional image-based car backing image system can only cover a limited area around the tail of the car, while blind areas around the car and the head of the car undoubtedly increase the hidden danger of safe driving, and particularly collision and scratch events are easy to occur in narrow and congested urban areas and parking lots. Therefore, in order to enlarge the field of vision of the driver, the driver must be able to sense the environment of 360 ° in all directions, which requires the cooperation of a plurality of vision sensors, and then a whole set of video images around the entire vehicle is formed through video synthesis processing. The panoramic looking around system is produced in the background of the above requirements.
The panoramic all-around viewing system is characterized in that 3 or more wide-angle cameras capable of covering all view field ranges around the vehicle are erected around the vehicle, namely, the information of surrounding images is obtained through the wide-angle cameras, a plurality of paths of images acquired at the same moment are processed into a vehicle body top view of 360 degrees around the vehicle, and finally the vehicle body top view is displayed on a screen of a center console; specifically, peripheral image information is input to a controller host to perform image correction, image splicing, white balance processing, gray scale adjustment, model rendering and the like, and finally, the processed image is output to a screen terminal to be displayed, so that the whole vehicle environment visual perception is provided for a user, a driver can clearly check whether obstacles exist around the vehicle and know the relative direction and distance of the obstacles, and the driver is helped to park the vehicle easily. Therefore, the panoramic all-round looking system is very visual, does not have any blind spot, can assist a driver to control the vehicle to park in the place or pass through a complex road surface easily, and effectively reduces the occurrence of accidents such as scraping, collision, collapse and the like.
However, because the cameras in the panoramic all adopt coaxial connectors to be connected to the host power supply, there are two systems in the cameras: one is a transmission system formed by a serializer chip TX, which requires a host to configure a register through an I2C (Inter-Integrated Circuit) backchannel control, but this step needs a front-end ISP (Image Signal Processing) to provide a PCLK clock; the other is an image acquisition and processing system consisting of a sensor and an ISP (Internet service provider), the system does not need a host computer end to configure, a FLASH chip can automatically configure the ISP after a camera is powered on, and a clock signal, a line-field synchronization signal and a data signal are provided for a rear-end serializer chip TX.
In the related art, each camera in the panoramic all-round looking system generally needs to be powered on and initialized in sequence at random, and generally, the initialization stabilization time of a single camera needs about 300-400 ms. Specifically, for example, a panoramic looking-around system includes 4 cameras (camera a, camera B, camera C, and camera D, respectively), and then the initialization process of each camera in one cycle period may be: powering on and Resetting (RESET) the camera A, and starting to initialize the camera A after waiting for 400 milliseconds; after the initialization of the camera A is completed, the camera B is powered on and reset and waits for 400 milliseconds, the camera B starts to be initialized, and the camera C and the camera D are sequentially initialized in the same way. Therefore, when the camera A receives an external image signal after completing the power-on initialization, the camera B, the camera C and the camera D do not complete the power-on initialization, and in a cycle period of the power-on initialization of the camera, the panoramic host in the panoramic all-around system is powered on and started at the moment, but since the camera B, the camera C and the camera D do not complete the initialization, the ISP parameter information of the camera is not configured, and further the all-around host cannot interact with the camera B, the camera C and the camera D to cause no image output on a screen.
Therefore, when the whole vehicle is at or above the ACC gear and the whole vehicle display terminal, the look-around host and the cameras are all at the starting stage, after the whole vehicle display terminal is started, the cameras need to be initialized in sequence in a random and circular mode, so that the look-around host can initialize and configure the serializer chip TX when part of the cameras ISP do not provide a stable PCLK signal for the serializer chip TX, further the serializer chip TX configuration is invalid, and the problem of abnormal image display on the whole vehicle display terminal is caused.

In the embodiment of the present application, the working principle of the camera power-on initialization control method will be further explained and explained.
In the prior art, each camera in the panoramic all-around system generally needs to be powered on and initialized in sequence in a random cycle, and generally, the initialization stabilization time of a single camera needs to be about 300-400 ms. The inventor finds that, because each camera in the panoramic all-round system is powered on circularly at random, different cameras are powered on randomly within a circular power-on period, so that in a circular power-on period, part of the cameras may not be initialized yet, and the all-round host computer is powered on and started up, at this time, ISP parameter information of the cameras is not configured yet, and if the ISP parameters of the cameras are written into the all-round host computer, the ISP parameters are not successfully written, and further no image is output on a screen. In addition, the inventor also finds that when the camera is powered on, the PCLK clock signal of the I2C needs to be close to one second to reach the stable state, and if the ISP is configured through the I2C at this time, the ISP-related parameters may be written unsuccessfully, and the image display is abnormal.
Therefore, in order to solve the above problems, in the embodiment of the present application, the initialization timing sequence of the cameras is optimized, that is, the power-on detection logic of each camera is changed to uniformly power on and reset the cameras of the whole vehicle, and the initialization of the cameras is started after the cameras are powered on for 1 second (the 1 second is a first preset time), so as to ensure that each camera is powered on and outputs an image at the same time.
Specifically, after the camera is powered on for 1 second, initialization operation is performed on the serializer chip of the camera, that is, the host initializes and configures the camera through an I2C communication mode, including configuring the image format into a RAW10 format, configuring the video output resolution into 1280X720 and 30fps, and configuring the pin bit of the serializer chip into the highest bit to the lowest bit of the corresponding image data bit. After the configuration of the serializer chip is finished, the serializer chip configures the ISP chip through the I2C joint, namely the output format of the ISP is set to YUV 422.
The power-on process of the whole system is as follows: after the surround-view host computer is powered on, the camera output power supply of the surround-view host computer can start to work, when the camera is powered on for 1 second, the surround-view host computer completes initialization of the camera, at the moment, the panoramic surround-view system is completely started, and the whole vehicle display terminal is started after 7 seconds, so that the time flow of initialization and parameter reading of the camera is solidified, and before the surround-view host computer is started, all the cameras complete initialization operation, so that the ISP can provide stable PCLK signals to the serializer chip, the serializer chip configuration is ensured to be effective, and the whole vehicle display terminal can normally display images. Through the camera power-on logic time sequence in the embodiment of the application, the synchronous image output of a plurality of cameras on the whole vehicle after power-on can be ensured.
The embodiment of the present application further provides an initialization control device on a camera, including:
the first processing unit is used for simultaneously and respectively carrying out power-on reset processing on each camera;
and the second processing unit is used for respectively initializing each camera after each camera is subjected to power-on reset processing with a first preset time length.
According to the embodiment of the application, all the cameras are powered on and reset at the same time, after the cameras are powered on for the preset time, the cameras are initialized, the time flow of initialization and parameter reading of the cameras is solidified, and therefore it is guaranteed that each camera completes initialization operation before the all-round host is started, the ISP can provide stable PCLK signals for the serializer chip, the serializer chip is enabled to be configured effectively, and the whole vehicle display terminal can normally display images.
Further, in the embodiment of the present application, the first preset time period is 1 second.
Exemplarily, after the camera is powered on, the PCLK clock signal of I2C needs to be close to one second to reach a stable state, so that the ISP can be configured through I2C after the camera is powered on for 1 second, and it is ensured that ISP related parameters can be successfully written into the all-round host, thereby ensuring that the image can be normally displayed. It should be noted that, the setting of the first preset time period to 1 second is only an example, and may also be determined according to actual requirements, for example, the first preset time period may also be set to 2 seconds, 3 seconds, and the like, and is not limited herein.
Furthermore, in this embodiment of the present application, the second processing unit is specifically configured to:
and simultaneously, initializing and configuring the image format, the video output resolution, the pin bit of the serializer chip and the ISP output format of each camera.
Illustratively, the image format may be configured as RAW10 format, the video output resolution may be configured as 1280X720, 30fps, the pin bits of the serializer chip may be configured to correspond to the most significant to the least significant of the image data bits, and the output format of the ISP may be configured as YUV 422. It should be noted that the image format, the video output resolution, the pin bit configuration, and the configuration of the output format of the ISP are only presented as examples, and may also be determined according to actual requirements, and are not limited herein.
Further, in this embodiment of the present application, the second processing unit is further configured to: and starting the whole vehicle display terminal within a second preset time length.
Exemplarily, the second preset time period may be set to be 7 seconds to ensure that the entire vehicle display terminal can normally display. It should be noted that, the 7 seconds is merely an example, and the second preset time period may be determined according to a specific screen feedback time, and is not limited herein.
In the embodiment of the present application, the working principle of the initialization control device for camera power-on will be further explained and illustrated.
The initialization time sequence of the cameras is optimized, namely, the power-on detection logic of each camera is changed into unified power-on and reset of the cameras of the whole vehicle through the first processing unit and the second processing unit, and the cameras start to initialize after being powered on for 1 second (the 1 second is a first preset time), so that the cameras are enabled to finish power-on and output images at the same time.
Specifically, after the cameras are controlled to be powered on and reset for 1 second through the first processing unit, the serializer chips of the cameras are initialized through the second processing unit, wherein the first processing unit and the second processing unit can be integrated into the panoramic all-around system, namely, the second processing unit in the all-around host initializes and configures the cameras through an I2C communication mode, and the method includes configuring an image format into a RAW10 format, configuring video output resolutions into 1280X720 and 30fps, and configuring pin bits of the serializer chips to correspond to the highest bit to the lowest bit of image data bits. After the configuration of the serializer chip is finished, the serializer chip configures the ISP chip through the I2C joint, namely the output format of the ISP is set to YUV 422.
The power-on process of the whole system is as follows: after the surround-view host computer is powered on, the camera output power supply of the surround-view host computer can start to work, when the camera is powered on for 1 second, the surround-view host computer completes initialization of the camera, at the moment, the panoramic surround-view system is completely started, and the whole vehicle display terminal is started after 7 seconds, so that the time flow of initialization and parameter reading of the camera is solidified, and before the surround-view host computer is started, all the cameras complete initialization operation, so that the ISP can provide stable PCLK signals to the serializer chip, the serializer chip configuration is ensured to be effective, and the whole vehicle display terminal can normally display images.
