The following describes a method, a device, a vehicle and a storage medium for prolonging the service life of a vehicle-mounted camera according to an embodiment of the application with reference to the accompanying drawings. In order to solve the problems in the prior art, the application provides a service life extension method of a vehicle-mounted camera, in the method, when a vehicle is in a sentinel mode and the surrounding environment of the vehicle is abnormal, high frame rate monitoring is kept, so that the situation that the surrounding environment of the vehicle cannot be clearly recorded in extreme cases is effectively avoided, when the surrounding environment of the vehicle is normal, the exposure frame rate of the vehicle-mounted camera is reduced, the purpose of prolonging the service life of the camera is achieved through reducing the exposure frame rate, and therefore the exposure frame rate of the vehicle-mounted camera is dynamically adjusted based on the actual condition around the vehicle, and the service life of the vehicle-mounted camera is prolonged while the normal monitoring of the vehicle is achieved. Thus, the problems that the related art does not consider the hardware life decay caused by turning on the vehicle sensor for a long time, and in extreme cases, the situation of the vehicle periphery may not be recorded clearly, and the like are solved.
The vehicle of the embodiment of the application can be provided with a high-order intelligent driving auxiliary system, and the vehicle end is provided with a driving domain controller with great calculation power, and signals of sensing sensors (such as a front-view long-distance camera, a front-view short-distance camera, a peripheral-view camera, a rear-view camera, a panoramic camera, a millimeter wave radar, a laser radar and the like) are connected into the driving domain controller.
Specifically, fig. 1 is a schematic flow chart of a method for prolonging service life of a vehicle-mounted camera according to an embodiment of the present application.
As shown in fig. 1, the service life extension method of the vehicle-mounted camera comprises the following steps:
in step S101, a current mode of the vehicle is detected.
The current mode can comprise a sentry mode and the like, and the sentry mode is taken as an example, and the embodiment of the application can prolong the service life in a mode of reducing the exposure frame rate when the vehicle is in the sentry mode, so that whether the vehicle is in the sentry mode or not needs to be detected for subsequent exposure frame rate adjustment of the vehicle-mounted camera.
In step S102, upon detecting that the current mode is the sentinel mode, the actual state of the vehicle is identified.
The sentry mode of the embodiment of the application means that potential threats can be detected through an external camera of the vehicle when the vehicle is in a parking state. The user can view the video information of cameras around the car body in real time through the mobile phone, once the car is collided or moved, the external camera can record the environment around the car, and the car owner is notified through the mobile phone APP/short message.
According to the embodiment of the application, after the sentry mode of the vehicle is started, the driving domain controller controls the vehicle-mounted camera to monitor the surrounding situation of the vehicle, and before the abnormal situation occurs, the exposure frequency of the camera is reduced in a low-consumption control mode, so that the service life of the camera is prolonged. Therefore, the embodiment of the application can detect the current mode of the vehicle so as to dynamically adjust the frame rate of the vehicle-mounted camera according to the actual working condition of the vehicle.
In one embodiment of the application, identifying an actual state of a vehicle includes: when the preset abnormal acceleration signal is detected, the actual state is judged to be the preset abnormal state, otherwise, the actual state is judged to be the preset normal state.
It can be understood that the embodiment of the application can monitor the acceleration signal to judge whether the vehicle has abnormal conditions, and can judge that the vehicle is abnormal when the acceleration signal is detected so as to adjust the exposure frame rate of the camera in time.
In step S103, when the actual state is a preset normal state, the vehicle-mounted camera is controlled to collect video data of the surrounding environment of the vehicle at the first target exposure frame rate, otherwise, the vehicle-mounted camera is controlled to collect video data of the surrounding environment of the vehicle at the second target exposure frame rate greater than the first target exposure frame rate, so that the service life of the vehicle-mounted camera is prolonged by reducing the exposure frame rate when the actual state is a preset normal state.
The first target exposure frame rate and the second target exposure frame rate may be specifically set according to practical situations, for example, the first target exposure frame rate is set to 5fps, and the second target exposure frame rate is set to 30fps, which is not specifically limited.
According to the embodiment of the application, after the sentry mode of the vehicle is started, the driving domain controller controls the panoramic camera to work, and the frame rate of the vehicle-mounted camera is dynamically adjusted by identifying the actual state of the vehicle. When the vehicle is in a normal state, the exposure frequency of the camera is reduced, so that the service life of the camera is prolonged, and when the vehicle is in an abnormal state, the exposure frame rate of the vehicle-mounted camera is increased, so that a clearer picture can be obtained.
Specifically, the embodiment of the application can control the corresponding camera video deserializer through a high-power SoC (System on a chip) in the driving domain controller, keep high frame rate monitoring when abnormal acceleration signals are detected and the surrounding environment of the vehicle is abnormal, can control the vehicle-mounted camera to collect the surrounding environment of the vehicle at the exposure frame rate of 30fps so as to effectively avoid the situation that the surrounding environment of the vehicle cannot be clearly recorded in extreme cases, reduce the exposure frame rate of the vehicle-mounted camera when the surrounding environment of the vehicle is normal, and reduce the exposure frame rate of the vehicle-mounted camera to 5fps, thereby realizing the purpose of prolonging the service life of the camera. As shown in table 1, when the vehicle is in the sentinel mode, the camera uses 8 hours per day at a frame rate of 30fps for example, and the longest use time is about 2.5 years. Wherein, table 1 is an example table of service life extension of the vehicle-mounted camera.
TABLE 1
| Use conditions | Camera frame rate | Duration of each day | Longest duration of time |
| Normal use | 30fps | 2h | For 10 years |
| Sentinel mode | 30fps | 8h | About 2.5 years |
| Sentinel mode | 5fps/30fps | 7h/1h | Estimated about 8 years |
In one embodiment of the present application, when determining that the actual state is the preset abnormal state, the method further includes: reading first video data in a first preset time period before the vehicle is in an abnormal state; collecting second video data in a second preset time period after the vehicle is in an abnormal state; uploading the first video data and the second video data value to a preset storage terminal so as to enable the video data before and after the preset abnormal state to exist.
The first preset duration and the second preset duration may be set and calibrated according to actual situations, for example, 15s, and are not limited specifically.
Specifically, when the current state of the vehicle is abnormal, the embodiment of the application can receive the emergency request signal sent by the driving domain controller, and after receiving the request signal, the embodiment of the application can upload the video data collected by the vehicle-mounted camera to the storage terminal within a certain time before and after the abnormal condition, so that the vehicle provides corresponding evidence after being maliciously damaged, and the user is helped to trace back to the responsible person.
In one embodiment of the present application, when determining that the actual state is the preset abnormal state, the method further includes: generating abnormal prompt information based on a preset abnormal state, and sending the abnormal prompt information to a preset user terminal.
It can be understood that when the state of the vehicle is abnormal, the embodiment of the application can timely send the abnormal prompt information to the user terminal, timely remind the driver to check the surrounding environment of the vehicle and make a reaction, thereby avoiding accidents.
In one embodiment of the present application, before identifying the actual state of the vehicle, further comprising: initializing an on-board camera by using a preset initialization strategy; when the initialization of the vehicle-mounted camera is detected to be completed, controlling the exposure frame rate of the vehicle-mounted camera to be a second preset exposure frame rate, otherwise, generating a fault maintenance prompt of the vehicle-mounted camera.
It can be understood that the embodiment of the application can initialize the vehicle-mounted camera before the actual state of the vehicle is identified, so as to ensure that the vehicle-mounted camera can work normally. If the initialization is successfully completed, the embodiment of the application can control the exposure frame rate of the vehicle-mounted camera to be the second preset exposure frame rate to collect the surrounding environment information, and then correspondingly adjust according to the state of the vehicle. If the initialization is not finished or the self-checking is abnormal, generating a fault maintenance prompt so as to prompt a user to overhaul in time.
The global path planning method for the proxy parking in the embodiment of the application is described in detail below through a specific embodiment.
As shown in fig. 2, the embodiment of the application can be configured with a panoramic camera, a driving domain controller, a combined navigation controller, a cabin domain controller (with TF card slot), a microphone, a TF (Trans-flash) card and a T-BOX (Telematics box) which are required by intelligent driving assistance. The concrete introduction is as follows:
1) Panoramic camera: FOV (Field of View) is 192 degrees, the pixel is 200 ten thousand, the frame rate is 30fps, the short-distance video stream data of 360 degrees of one week of the whole vehicle is provided, namely, the horizontal visual angle HFOV (Horizontal Field of View) is about 192 degrees, the vertical visual angle VFOV (VERTICAL FIELD of View) is about 150 degrees, and the design service life is as follows: 2 hours x 365 (days) x 10 (years) =7300 hours. Panoramic camera, integrated navigation controller, cabin area controller (with TF card slot), microphone, TF (Trans-flash) card, T-BOX (Telematics box) that intelligent driving assistance needs. As shown in fig. 3, in the panoramic camera sensor arranged around the vehicle according to the embodiment of the application, the original video stream can be input into the driving domain controller through an LVDS (Low Voltage DIFFERENTIAL SIGNALING) signal line, and the signal of the integrated navigation controller is accessed into the driving domain controller through CANFD
2) The physical core parameter of the driving domain control is AI (artificial intelligence) calculated power of the SoC, and the calculated power is required to be 254AI TOPS (Tera Operations Per Second) to 508AI TOPS so as to control the exposure frame rate of the panoramic camera. After the sentry mode is started, when the vehicle state is normal, the exposure frame rate of the camera is controlled to be 5fps, the original image data of the panoramic camera is packaged, and the original image data is output to the cabin controller for storage in real time. And meanwhile, the acceleration signal of the accessed integrated navigation controller is monitored to judge whether the vehicle has abnormal conditions or not. When the state of the vehicle is abnormal, the exposure frame rate of the camera is switched to 30fps in time. And if the sentinel mode is not started, stopping the exposure of the panoramic camera.
3) The integrated navigation controller detects the acceleration signal of the vehicle and sends the acceleration signal to the driving domain controller in time through the CAN signal.
4) The core capability of the cabin domain controller is to receive the original video data stream transmitted by the driving domain controller, and combine the sound information of the microphone and store the original video data stream into the TF card. Storage space: the built-in memory should store video data for more than or equal to 4 hours, and the estimated capacity is about 28.8GB, namely a built-in 32GB eMMC memory; has tamper-proof function. And (3) power-off protection: BAT abnormal power failure needs to ensure that video files at the time of power failure are normal (a standby power source such as a super capacitor needs to be added). As shown in fig. 4, four paths of original data of the panoramic camera are transmitted to the cabin controller through the LVDS signal line in a YUV422 format, the cabin controller receives the video data stream and the sound signal of the microphone, and then stores the video data stream and the sound signal of the microphone in the TF in a certain data format, and when the vehicle state is abnormal, the T-BOX acquires video data of 15 seconds before and after the vehicle abnormality from the cabin controller and uploads the video data to the cloud server.
5) And after receiving an emergency request signal sent by the driving domain controller, the T-BOX is used as a connecting medium between the vehicle end and the cloud end, and the cabin domain controller stores video data 15 seconds before and after the abnormality of the vehicle and uploads the video data to the cloud end server.
The overall vehicle scene implementation of the global path planning method for parking the passengers in the embodiment of the application is shown in fig. 5, and the specific steps are as follows:
s501: after the user gets off the bus and starts the sentinel function mode, if abnormality is detected, step S502 is executed, and if the abnormality is normal, step S504 is executed;
S502: the driving domain controller can complete power supply, initialization and self-checking of the panoramic camera and receive video data of the camera; if the initialization and self-checking of the camera are normal, the step S503 is entered, otherwise, the step S504 is entered;
s503: the SoC of the driving domain controller controls the video deserializer of the camera, and carries out data circulation according to the data flow mode shown in fig. 4;
s504: the driving domain controller sends out fault information, and the cloud prompt user overhauls the fault information;
S505: after the cabin domain controller normally receives the original data stream transmitted by the driving domain controller, the cabin domain controller combines the sound signals of the microphone to store the data into the TF card. The user can play back the data stored in the TF card in real time on a central control screen of the vehicle, or take the TF card down from the vehicle end and put it on a computer for playing back video;
s505: detecting abnormal conditions around the vehicle;
s507: in an emergency, the T-BOX acquires video data of 15 seconds before and after the abnormality of the vehicle from the cabin controller and uploads the video data to the cloud server;
