[0001] This application relates to the technical field of camera heat dissipation, and particularly to a camera control method, device, and vehicle. Background Art

[0002] Although existing solutions have, to some extent, solved the heat dissipation problem of camera modules, there are still some problems and drawbacks.

Second, existing heat dissipation devices may increase the weight of the camera module, which may have a negative impact on the energy consumption and performance of the vehicle. Finally, existing heat dissipation devices may increase the manufacturing cost of the camera module, which may be an important consideration for vehicle manufacturers.

[0013] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0014] Although the existing heat dissipation solutions for camera modules have been improved, these improvements mainly focus on hardware. Although these improvements can enhance the heat dissipation effect, they still face problems such as space occupation, weight increase, and rising manufacturing costs. Therefore, on the basis of hardware improvement of the camera module, how to dissipate heat efficiently remains a challenge to be solved urgently.

[0015] In view of the above problems, the embodiments of the present application provide a camera control method, which identifies the vehicle scenario, adjusts working parameters such as the frame rate and resolution of the camera according to different working conditions, and monitors its temperature in real time to dynamically adjust the state of the heat dissipation device to ensure the temperature control effect of the camera module.

[0016] See Figure 1 , in the first embodiment of the present application, a camera control method is provided, including the steps:

[0017] S101, determine the current scenario of the vehicle;

[0018] S102, determine the working parameters of the camera module according to the current scenario of the vehicle and the surrounding environment of the vehicle. The camera module supports working under at least two different working parameters, and the working parameters include the frame rate and the resolution;

[0019] S103, adjust the working state of the heat dissipation device according to the working temperature of the camera module under the corresponding working parameters. The heat dissipation device is arranged on the camera module.

[0020] The embodiments of the present application first determine the working state of the vehicle in the current scenario to match the best working parameters for the camera module, so that the heat generation of the camera module can be minimized while meeting the scenario requirements, thereby optimizing the heat dissipation performance of the camera module. Then, when adjusting the working parameters cannot reduce the working temperature of the camera module, an external heat dissipation device is further used to quickly dissipate heat to improve the heat dissipation effect during the use of the camera module.

[0021] Specifically, the scenarios where the vehicle is located include but are not limited to the vehicle being in reverse mode, the vehicle being in intelligent driving mode, the vehicle being in low-speed driving mode, and the vehicle being in parking monitoring mode. In practical applications, the vehicle generally needs to use the camera module for a long time in these scenarios. Since these scenarios do not occur independently, multiple scenarios may also occur simultaneously. In order to be able to match the best working parameters for the camera module, it is necessary to uniquely identify and determine the current scenario of the vehicle.

[0022] In some alternative embodiments, determining the current scenario in which the vehicle is located includes: detecting the gear position of the vehicle; when the gear position is in reverse gear, determining that the scenario is the vehicle in reverse mode; when the gear position is in forward gear, detecting whether the vehicle has the intelligent driving mode enabled: if the vehicle has the intelligent driving mode enabled, determining that the scenario is the vehicle in intelligent driving mode; if the vehicle does not have the intelligent driving mode enabled, when the vehicle speed is less than or equal to a preset first speed threshold: determining that the scenario is the vehicle in low-speed driving mode, and when the vehicle speed is greater than the preset first speed threshold, continuously detecting the gear position of the vehicle;

[0023] When the gear position is in park gear, if the vehicle has the sentry mode enabled, determining that the scenario is the vehicle in parking monitoring mode, and if the vehicle does not have the sentry mode enabled, continuously detecting the gear position of the vehicle;

[0024] When the gear position is in neutral gear, if the vehicle speed is greater than a preset second speed threshold, determining that the scenario is the vehicle in low-speed driving mode, and if the vehicle speed is less than or equal to the preset second speed threshold, continuously detecting the gear position of the vehicle.

[0025] Specifically, the gear positions of the vehicle generally include park gear, reverse gear, forward gear, and neutral gear. Among them, the park gear is also called the P gear, which is used to lock the transmission when parking to prevent the vehicle from moving. The reverse gear is also called the R gear, which is used to make the vehicle move backward when reversing. The forward gear is also called the D gear, which is used for the vehicle to move forward normally, and the transmission will automatically select a suitable gear according to the vehicle speed and load. The neutral gear is also called the N gear. If the vehicle is in neutral gear, the power transmission is disconnected and the vehicle generally does not move. The embodiments of the present application do not consider the case of neutral gear. In addition, some vehicles may also be equipped with a sport gear and a low gear. The sport gear is also called the S gear, which is used to provide a higher shift setting of the engine speed to enhance the acceleration performance, similar to the forward gear situation; the low gear is also called the L gear, which is used to limit the transmission to operate in a low gear, and similar to the forward gear, the vehicle is in a forward driving state.

[0026] When the gear position is in reverse gear, the vehicle will move backward and activate the corresponding camera module to obtain an image of the rear of the vehicle, so that the driver can understand the road conditions behind the vehicle through this image to ensure the safety of reversing. In this embodiment, if it is detected that the gear position is in reverse gear, the vehicle will activate the camera module, radar, etc. installed at the rear of the vehicle to obtain the blind spot road conditions behind the vehicle, which is convenient for the driver to reverse safely. At this time, the vehicle system will determine that the scenario in which the vehicle is located is the vehicle in reverse mode.

[0027] When the gear is in the park position, the vehicle will take a series of measures to ensure the safety and stability of the vehicle in the parked state, including but not limited to enabling the Sentry Mode. Specifically, the Sentry Mode is a security monitoring mode that mainly provides additional monitoring protection when the vehicle is parked. After enabling the Sentry Mode, the vehicle will use cameras, radars, and other sensors to monitor the surrounding environment in real time to detect potential threats or abnormal activities. When the vehicle is in the Sentry Mode and detects an object approaching or colliding with the vehicle, the vehicle may take measures such as activating a warning sound or flashing the headlights to alert, and automatically record videos or take pictures to preserve evidence. In addition, the Sentry Mode of some vehicles can also push alerts to the owner's mobile phone. In this embodiment, if the vehicle's gear is in the reverse gear and the Sentry Mode is enabled, the corresponding camera module will be activated to obtain images of the vehicle's surroundings and monitor the surrounding environment in real time. At this time, the system will determine that the vehicle is in the parking monitoring mode.

[0028] When the gear is in the drive position, the vehicle will move forward. In some vehicles that support intelligent driving functions or assisted driving functions, the vehicle has multiple driving modes, including but not limited to the intelligent driving mode. Users can enable the corresponding intelligent driving function or assisted driving function by switching the driving mode. Specifically, the intelligent driving mode is an advanced driver assistance system (referred to as Advanced Driver Assistance Systems in English, generally abbreviated as ADAS), which aims to automatically control the speed, direction, acceleration, and braking of the vehicle according to road, traffic, and environmental conditions. This mode usually integrates multiple sensors (such as cameras, radars, lidars, etc.). When the intelligent driving mode is enabled, the vehicle can identify pedestrians, vehicles, traffic signals, and obstacles, and can even perform autonomous driving functions according to the set route; or the vehicle can identify pedestrians, vehicles, traffic signals, and obstacles, etc., so as to provide driver fatigue detection, intelligent headlight control, adaptive cruise control, lane departure warning, lane keeping assistance, lane change assistance, and emergency braking systems and other assisted driving functions during the vehicle's driving process, so as to improve driving safety and optimize travel efficiency. In this embodiment, when the vehicle enables the intelligent driving mode, the vehicle will activate the corresponding camera module to obtain images, and obtain corresponding decision-making instructions through computational analysis of the images, so as to control the vehicle according to the decision-making instructions to achieve autonomous driving of the vehicle. At this time, the system will determine that the vehicle is in the intelligent driving mode.

[0029] Furthermore, in addition to having intelligent driving functions or assisted driving functions, some vehicles also have the function of turning on the camera to monitor the surrounding environment at low speeds. For example, when the vehicle passes through a narrow space or a complex environment at low speed, the vehicle will use cameras, radars, and sensors to provide a view of the surrounding area of the vehicle, helping the driver drive safely in a narrow space or a complex environment. Therefore, in this embodiment, if the gear is in the forward gear and the vehicle's intelligent driving mode is not turned on, the vehicle will monitor whether the vehicle speed is within a preset low-speed threshold range, that is, less than or equal to a preset first speed threshold. If so, the function of turning on the camera to monitor the surrounding environment at low speed will be activated, and at this time, the system will determine that the vehicle is in the low-speed driving mode.

[0030] It should be noted that the intelligent driving function or assisted driving function of the vehicle may also include the function of turning on the camera to monitor the surrounding environment at low speeds. In some alternative embodiments, when the vehicle's intelligent driving mode is turned on, the vehicle speed is monitored. If the vehicle speed is less than or equal to the preset first speed threshold, it is determined that the vehicle is in the low-speed driving mode. If the vehicle speed is greater than the preset first speed threshold, it is determined that the vehicle is in the intelligent driving mode. Additionally, when the vehicle's intelligent driving mode is turned on, the vehicle speed is no longer monitored, but the system will determine that the vehicle is in the intelligent driving mode. Only when the gear is in the forward gear and the vehicle's intelligent driving mode is not turned on, it is monitored whether the vehicle speed is within the preset low-speed threshold range, that is, less than or equal to the preset first speed threshold. If so, the function of turning on the camera to monitor the surrounding environment at low speed will be activated, and the system will determine that the vehicle is in the low-speed driving mode.

[0031] When the gear is in neutral, the vehicle is generally in a braking or stopped state, but in practice, there may also be a situation of coasting in neutral. For this reason, in this embodiment, when the vehicle is in neutral, it is monitored whether the vehicle speed is greater than a second speed threshold (for example, the second speed threshold is zero). If so, the system will determine that the vehicle is in the low-speed driving mode, and thus turn on the corresponding camera module to obtain images of the surrounding area of the vehicle. This not only reminds the driver that the vehicle is currently in a moving state but also provides the driver with surrounding images, enabling the driver to take normal defensive measures and avoid vehicle accidents in the case of coasting in neutral.

[0032] The embodiments of the present application accurately and uniquely determine the current scene of the vehicle by identifying the gear of the vehicle and the driving state in different gears, so that the vehicle can match the best working parameters for the corresponding camera module according to the working state of the vehicle in the current scene, thereby optimizing the heat generation of the camera module.

[0033] Among them, the vehicle needs to enable the corresponding camera module in different scenarios. However, the working states of the vehicle in different scenarios will be different. Therefore, how to reasonably set the working parameters of the camera module according to the working states of each scenario is a technical problem that needs to be solved in practical applications.

[0034] In some alternative embodiments, when the scenario is that the vehicle is in reverse mode, according to the current scenario of the vehicle and the surrounding environment of the vehicle, the working parameters of the camera module are determined, including: determining the target recognition types within the reverse monitoring range, where the target recognition types include people and objects; when there is only an object within the reverse monitoring range, adjusting the camera module to work at a first frame rate and a first resolution; when there is a person within the reverse monitoring range, adjusting the camera module to work at a second frame rate and a second resolution, where the second frame rate is greater than the first frame rate and the second resolution is greater than the first resolution.

[0035] Specifically, the reverse monitoring range refers to the detection range of the sensor provided on the vehicle for reverse monitoring. When the vehicle is reversing, the method of determining the target recognition types within the reverse monitoring range is not unique, including but not limited to using a camera, a radar, or a combination thereof. If a camera is used, the camera module is initialized to work at a first frame rate and a first resolution, the video stream image behind the vehicle is collected through the camera, and then an image recognition algorithm is adopted to continuously recognize the target recognition types behind the vehicle in real time through the video stream obtained by the camera, such as people and objects. If the image recognition algorithm recognizes a person, or recognizes both a person and an object at the same time, the camera module is adjusted to work at a second frame rate and a second resolution. If the image recognition algorithm recognizes only an object, the camera module is adjusted to work at a first frame rate and a first resolution. Among them, the image recognition algorithm here includes a pre-trained deep learning model or a machine learning model, and these algorithms can detect and classify different objects in the image.

[0036] It can be understood that the camera module supports multiple frame rates and resolutions. The first frame rate and the second frame rate are only two of the multiple frame rates supported by the camera module. Preferably, the first frame rate can be the minimum frame rate supported by the camera module (for example, 45 FPS), and the second frame rate is the maximum frame rate supported by the camera module (for example, 60 FPS). In addition, the first resolution and the second resolution are also only two of the multiple resolutions supported by the camera module. Preferably, the first resolution can be the minimum resolution supported by the camera module (for example, 720P), and the second resolution is the maximum resolution supported by the camera module (for example, 1080P).

[0037] In the embodiments of the present application, by identifying people and objects within the reverse monitoring range, the camera module is respectively adjusted to operate at the first frame rate and the first resolution, or at the second frame rate and the second resolution, so as to match the optimal operating parameters for the camera module. When the camera module meets the requirements of the scenario, the heat generation can be minimized as much as possible, thereby optimizing the heat dissipation performance of the camera module and improving the heat dissipation effect during the use of the camera module.

[0038] In some alternative embodiments, when the vehicle is in the intelligent driving mode, the operating parameters of the camera module are determined according to the current scenario of the vehicle and the surrounding environment of the vehicle, including: when the vehicle activates the intelligent driving mode, the camera module is initialized to operate at the first frame rate and the first resolution, and whether there is a target recognition type within the safe range around the vehicle is monitored; when there is a target recognition type within the safe range around the vehicle, the camera module is adjusted to operate at the second frame rate and the second resolution, where the second frame rate is greater than the first frame rate and the second resolution is greater than the first resolution; when there is no target recognition type within the safe range around the vehicle, the camera module is maintained or adjusted to operate at the first frame rate and the first resolution.

[0039] Specifically, the safe range around the vehicle can be a preset range centered on the vehicle, or the detection range of the vehicle's vision sensor. The target recognition types include people and objects. People can be pedestrians within the safe range around the vehicle, and objects can be cars, traffic signs, etc. In practical applications, the image data of the surrounding environment is transmitted to the vision processing unit in the vehicle intelligent driving system. The vision processing unit includes, but is not limited to, deep learning algorithms such as convolutional neural networks. The intelligent driving system can identify objects, lane lines, signs, pedestrians, etc. from the images, and these targets can be divided into two target recognition types: people and objects. For example, in this embodiment, assuming the target recognition type is a pedestrian, when the vehicle activates the intelligent driving mode, the camera module is initialized to operate at the first frame rate and the first resolution, and the images collected by the camera module are recognized by the vision processing unit to determine whether there are pedestrians in the images. If there are, the camera module is adjusted to operate at the second frame rate and the second resolution; if not, the camera module is maintained to operate at the first frame rate and the first resolution.

[0040] Similarly, in this embodiment, the camera module supports multiple frame rates and resolutions. The first frame rate and the second frame rate are only two of the multiple frame rates supported by the camera module. Preferably, the first frame rate can be the minimum frame rate supported by the camera module (e.g., 45 FPS), and the second frame rate is the maximum frame rate supported by the camera module (e.g., 60 FPS). In addition, the first resolution and the second resolution are also only two of the multiple resolutions supported by the camera module. Preferably, the first resolution can be the minimum resolution supported by the camera module (e.g., 720P), and the second resolution is the maximum resolution supported by the camera module (e.g., 1080P).

[0041] In the embodiment of the present application, the working parameters of the camera module are adjusted to the second frame rate and the second resolution according to the target recognition type recognized by the vehicle in the intelligent driving mode scenario. Otherwise, it is default that the camera module works at the first frame rate and the first resolution. Since the second frame rate is greater than the first frame rate and the second resolution is higher than the first resolution, the best frame rate and resolution are matched for the camera module in different working states in the intelligent driving mode scenario of the vehicle, so that the heat generation of the camera module can be minimized as much as possible while meeting the scenario requirements, thereby optimizing the heat dissipation performance of the camera module and improving the heat dissipation effect during the use of the camera module.

[0042] In some alternative embodiments, when the scenario is that the vehicle is in the low-speed driving mode, the working parameters of the camera module are determined according to the current scenario of the vehicle and the surrounding environment of the vehicle, including: turning on the camera and initializing the camera module to work at the first frame rate and the first resolution; when there is a target recognition type within a preset distance around the vehicle or a target recognition type approaches the vehicle at a high speed, controlling the camera module to work at the second frame rate and the second resolution, where the second frame rate is greater than the first frame rate and the second resolution is greater than the first resolution, and the target recognition type includes people and objects; when there is no target recognition type within the preset distance around the vehicle, controlling the camera module to work at the first frame rate and the first resolution.

[0043] Specifically, the preset distance around the vehicle refers to a set of distance thresholds pre-set by the system according to different driving functions and safety requirements. These thresholds are used to monitor the relative positions of obstacles or other vehicles around the vehicle to ensure driving safety. In this embodiment, the preset distance around the vehicle can preferably be the set distances on the left and right sides of the vehicle. When the vehicle is in the low-speed driving mode, the camera module is initialized to work at the first frame rate and the first resolution, and the vehicle's perception system (including but not limited to the image recognition system and the radar recognition system) is controlled to identify the target recognition type around the vehicle and the speed of the target recognition type. Further, when there is a target recognition type within the preset distance around the vehicle, the speed of the target recognition type is recognized. If the speed of the target recognition type is greater than the preset speed value, it is determined that the target recognition type is approaching the vehicle at high speed. If the speed of the target recognition type is less than or equal to the preset speed value, it is determined that the target recognition type is not approaching the vehicle at high speed. Among them, the specific implementation method for determining the speed of the target recognition type is not unique and will not be elaborated here.

[0044] If a target recognition type is recognized within the preset distance around the vehicle, or if a target recognition type is approaching the vehicle at high speed, the camera module is adjusted to work at the second frame rate and the second resolution. If no target recognition type is recognized within the preset distance around the vehicle, the camera module is restored or maintained to work at the first frame rate and the first resolution. In this embodiment, the target recognition type includes people and objects, or only includes people.

[0045] In this embodiment, the camera module supports multiple frame rates and resolutions. The first frame rate and the second frame rate are only two of the multiple frame rates supported by the camera module. Preferably, the first frame rate can be the minimum frame rate supported by the camera module (such as 45 FPS), and the second frame rate is the maximum frame rate supported by the camera module (such as 60 FPS). In addition, the first resolution and the second resolution are also only two of the multiple resolutions supported by the camera module. Preferably, the first resolution can be the minimum resolution supported by the camera module (such as 720P), and the second resolution is the maximum resolution supported by the camera module (such as 1080P). When no target recognition type is recognized within the preset distance around the vehicle, the camera module works at the lower first frame rate and the first resolution, which can reduce the heat generation, so that the camera can be prevented from overheating while ensuring low-speed monitoring; when a target recognition type is recognized within the preset distance around the vehicle, the camera module works at the higher second frame rate and the second resolution to obtain clearer images, thereby improving the accuracy of low-speed monitoring. Although this will cause an increase in the heat generation of the camera, as long as the target recognition type disappears, the camera will automatically return to work at the lower first frame rate and the first resolution to prevent the camera from overheating and improve the heat dissipation efficiency of the camera.

[0046] In the embodiment of the present application, when the vehicle is in the low-speed driving mode, the camera is turned on, and the camera module is initialized to work at the first frame rate and the first resolution; when it is recognized that there is a target recognition type within a preset distance around the vehicle, the camera module is controlled to work at the second frame rate and the second resolution, where the second frame rate is greater than the first frame rate and the second resolution is greater than the first resolution; when it is not recognized that there is a target recognition type within the preset distance around the vehicle, the camera module is controlled to work at the first frame rate and the first resolution, so as to match the best frame rate and resolution according to different working states of the vehicle, which not only reduces power consumption and data processing burden, saves system resources, but also improves the recognition accuracy of people and objects, enabling the camera to intelligently switch between heat generation and security monitoring, taking into account both efficiency and accuracy.

[0047] In some alternative embodiments, when the vehicle is in the parking monitoring mode, according to the current scene of the vehicle and the surrounding environment of the vehicle, the working parameters of the camera module are determined, including: when it is confirmed by radar that an object is approaching the vehicle, the camera is turned on, and according to the distance between the object and the vehicle, the working parameters of the camera module are determined; when it is determined by radar that no object is approaching the vehicle, the monitoring camera is turned off, and it is continuously determined by radar whether an object is approaching the vehicle.

[0048] Specifically, when the vehicle is in the parking monitoring mode, sensors such as radar, infrared sensors, and cameras can be used to monitor the surrounding conditions of the vehicle. For example, when the vehicle is parked in a lot and the sentry mode is turned on, first, radar is used to detect whether there is an object approaching the vehicle. The radar can detect whether the objects around the vehicle are static or dynamic. If the radar detects that the objects around the vehicle are static, the camera will not be turned on at this time to avoid heat generation by the camera. If the radar detects that the objects around the vehicle are dynamic, the camera will be turned on at this time to obtain surrounding images, and then the specific type of the object is determined through image recognition algorithms, and according to the distance between the object and the vehicle, the best working parameters are matched for the camera module.

[0049] Further, in an optional embodiment, the operating parameters of the camera module are determined according to the distance between the object and the vehicle, including: determining the motion state of the object, where the motion state includes a moving state and a stationary state; when the object is in the moving state, determining the distance between the object and the vehicle; when the distance between the object and the vehicle is within a first preset range, adjusting the camera module to operate at a first frame rate and a first resolution; when the distance between the object and the vehicle is within a second preset range, adjusting the camera module to operate at a second frame rate and a second resolution, where the second frame rate is greater than the first frame rate, the second resolution is greater than the first resolution, and the second preset range is smaller than the first preset range; when the object is in the stationary state, adjusting the camera module to operate at the first frame rate and the first resolution, or turning off the camera when the stationary time of the object exceeds a preset time.

[0050] Specifically, to determine whether the object is in the moving state or the stationary state, a radar, a camera, or a combination of a radar and a camera can be used. Among them, a radar (such as a millimeter-wave radar) can determine whether an object is static or dynamic by detecting the relative speed, distance, and direction of the object. The camera can identify the object through visual information and image processing algorithms and determine its motion state. For example, by identifying the change in optical flow between consecutive frame images through image processing algorithms, it can be determined whether the object is moving. In addition, by combining the radar and the camera, dynamic and static objects can be distinguished more accurately, improving the perception accuracy. For example, the motion state can be determined by combining the object type information (pedestrians, vehicles, etc.) obtained by the camera with the speed information of the radar.

[0051] In practical applications, multiple different distance ranges can be pre-divided with the vehicle as the center. According to the distance between the object and the vehicle, it can be determined which target distance range the object is in, and then an optimal operating parameter can be matched for the camera module. For example, the closer the object is to the vehicle, the higher the frame rate and resolution are matched for the camera module. On the contrary, the farther the object is from the vehicle, the lower the frame rate and resolution are matched for the camera module.

[0052] In the case where a first preset range and a second preset range are pre-divided, where the second preset range is smaller than the first preset range, if it is confirmed that the object is in a moving state and within the first preset range, the camera module is adjusted to operate at a lower first frame rate and a first resolution. At this time, the working parameters of the camera can meet the recognition of the object at this distance and can effectively reduce the heat generation of the camera module; if it is confirmed that the object is in a moving state and within the second preset range, the camera module is adjusted to operate at a higher second frame rate and a second resolution to obtain a clearer monitoring image. Preferably, the first frame rate and the first resolution are the minimum frame rate and the minimum resolution supported by the camera module, while the second frame rate and the second resolution are the maximum frame rate and the maximum resolution supported by the camera module.

[0053] In addition, the camera module can also support other frame rates and resolutions. For example, the camera also supports a third frame rate and a third resolution, where the third frame rate is greater than the first frame rate and less than the second frame rate, and the third resolution is greater than the first resolution and less than the second resolution.

[0054] In practical applications, a first preset range, a second preset range, and a third preset range can also be pre-divided. Among them, the first preset range, the second preset range, and the third preset range are three consecutive ranges, and the third preset range is smaller than the first preset range and greater than the second preset range. If it is confirmed that the object is in a moving state and within the first preset range, the camera module is adjusted to operate at a lower first frame rate and a first resolution. At this time, the working parameters of the camera can meet the recognition of the object at this distance and can effectively reduce the heat generation of the camera module; if it is confirmed that the object is in a moving state and within the second preset range, the camera module is adjusted to operate at a higher second frame rate and a second resolution to obtain a clearer monitoring image. Preferably, the first frame rate and the first resolution are the minimum frame rate and the minimum resolution supported by the camera module, while the second frame rate and the second resolution are the maximum frame rate and the maximum resolution supported by the camera module; if it is confirmed that the object is in a moving state and within the third preset range, the camera module is adjusted to operate at an intermediate third frame rate and a third resolution to obtain a clearer monitoring image and reduce the heat generation of the camera.

[0055] In addition, in practice, some objects approach the vehicle dynamically at first and then become static after entering a preset range. If an object becomes static within a preset range close to the vehicle, the camera module will continue to work at a high frame rate and high resolution at this time, generating a large amount of heat. To avoid this situation, a countdown can be started after the object becomes static. When the countdown expires, if the object remains static, the frame rate and resolution of the camera module can be adjusted to reduce heat dissipation, or the camera can be turned off. For example, if it is determined that the object is a person, the camera module is adjusted to work at a lower first frame rate and first resolution. If it is determined that the object is an object (not a person), the camera is turned off.

[0056] In the embodiments of the present application, the working parameters of the camera module are adjusted by determining the motion state of the object. When the object is in a moving state, the frame rate and resolution of the camera are adjusted according to the distance between the object and the vehicle. The closer the distance, the higher the frame rate and resolution. When the object is in a stationary state, the camera works at a lower frame rate and resolution, or the camera is turned off after the object has been stationary for a certain period of time. This dynamic adjustment can effectively reduce the heat generation of the camera and improve the heat dissipation effect.

[0057] In practice, the camera module may also work at a high frame rate and high resolution for a long time. At this time, the heat generation is large, which will cause the temperature of the camera module to rise. Once the temperature exceeds a reasonable temperature, the temperature cannot be reduced by adjusting the frame rate and resolution. At this time, auxiliary heat dissipation is required to reduce the working temperature to ensure the normal operation of the camera module.

[0058] In some alternative embodiments, the preset heat dissipation device on the camera module includes a thermoelectric cooler. According to the working temperature of the camera module under corresponding working parameters, the working state of the heat dissipation device is adjusted, including: when the working temperature of the camera module is greater than or equal to a preset temperature threshold, controlling the thermoelectric cooler to perform refrigeration work; or adjusting the power of the thermoelectric cooler according to the heat dissipation requirement of the camera module.

[0059] Specifically, the monitoring of the working temperature of the camera module is synchronized with the matching of the working parameters of the camera module. Once it is detected that the working temperature reaches the temperature threshold, the thermoelectric cooler is controlled to be powered on for refrigeration work. On the contrary, if the working temperature does not reach the temperature threshold, the working temperature is adjusted in the way of determining the working parameters of the camera module according to the current scene where the vehicle is located and the surrounding environment of the vehicle.

[0060] It can be understood that in practice, the heat dissipation device can also be other heat dissipation structures or components, and the embodiments of the present application do not limit this.

[0061] All the above alternative technical solutions can be combined arbitrarily to form alternative embodiments of the present application, which will not be elaborated one by one here.

[0067] In the embodiment of the present application, the best working parameters are matched for the camera module by first identifying the working state of the vehicle in the current scene, so that the heat generation of the camera module can be minimized while meeting the scene requirements, thereby optimizing the heat dissipation performance of the camera module.

[0072] In some embodiments, when the scenario is that the vehicle is in parking monitoring mode, the above-mentioned matching module 202 is further configured to turn on the camera when it is determined by radar that an object is approaching the vehicle, and determine the working parameters of the camera module according to the distance between the object and the vehicle; when it is determined by radar that no object is approaching the vehicle, turn off the monitoring camera and continuously determine by radar whether an object is approaching the vehicle.

[0074] In some embodiments, the heat dissipation device includes a thermoelectric cooler.

[0075] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0076] See Figure 3 and 4 In the third embodiment of the present application, a vehicle 3 is provided, which includes at least one camera module 31 and a controller 32. At least one heat dissipation device 33 is installed on each camera module 31, and the camera module 31 and the heat dissipation device 33 are respectively connected to the controller 32. The control includes at least a processor 401, a memory 402, and a computer program 403 stored in the memory 402 and executable on the processor 401. When the processor 401 executes the computer program 403, the above-mentioned various method embodiments are implemented. Or, when the processor 401 executes the computer program 403, the functions of each module in the above-mentioned device embodiments are implemented.

[0077] In this embodiment, the vehicle includes, but is not limited to, transportation tools such as sedans, trucks, buses, and driverless vehicles. In the vehicle, the camera module 31 is preferably a high-pixel vehicle-mounted camera. In this embodiment, the camera module 31 can be an 800M pixel camera, which has high definition and high sensitivity, and can provide clearer images, enabling the vision algorithm solution to more accurately identify and measure distances. Among them, the camera module 31 is installed at an appropriate position of the vehicle, such as above the front windshield, so as to be able to capture the road conditions ahead; or at the rear of the vehicle, for capturing the road conditions behind the vehicle.

[0078] The specific implementation of the heat dissipation device 33 on the camera module 31 is not unique. For example, the heat dissipation device 33 is preferably a semiconductor heat dissipation module or a semiconductor heat sink. When installing the heat dissipation device 33, the semiconductor heat dissipation module can be closely attached to the camera module 31 for rapid heat absorption. In this embodiment, the heat dissipation device 33 is preferably an efficient semiconductor heat dissipation module with a maximum heat dissipation power of 50W. Another example is that the heat dissipation device 33 is preferably a heat dissipation fan module, which is installed below the semiconductor heat dissipation module to exhaust the heat sucked out by the semiconductor heat dissipation module. In this embodiment, the heat dissipation device 33 is preferably a silent and efficient heat dissipation fan module with a maximum wind speed of 5m / s. In addition, the heat dissipation device 33 can also include a semiconductor heat dissipation module and a heat dissipation fan module at the same time, and both are installed on the camera module 31 simultaneously.

[0079] In addition, to facilitate monitoring the working temperature of the camera module 31, at least one thermistor can be installed on the camera module 31. The thermistor is installed near the camera module 31 to detect the temperature of the camera module 31. In this embodiment, the thermistor is preferably a thermistor with an accuracy of ±0.1°C. Exemplarily, in an actual application scenario, a temperature threshold is preset, for example, the temperature threshold is set to 60°C. When the thermistor detects that the temperature of the camera module 31 reaches 60°C, the semiconductor heat dissipation module and the heat dissipation fan module are controlled to start working to lower the temperature of the camera module 31. When the working temperature does not reach the temperature threshold, the working parameters of the camera module 31 are adjusted, including but not limited to adjusting the frame rate or / and resolution, and the best frame rate and resolution are matched for the camera module 31 according to the working state of the vehicle, and the frame rate and image quality of the camera are automatically reduced to reduce the generated heat.

[0080] There are many scenarios in which the vehicle is located, including but not limited to the vehicle being in reverse mode, the vehicle being in intelligent driving mode, the vehicle being in low-speed driving mode, and the vehicle being in parking monitoring mode.

[0081] When the vehicle is in reverse mode, only the reverse camera is enabled and the radar is used for assistance to identify the type of target recognition within the reverse monitoring range. If the target recognition type is only an object, then the camera module 31 will be adjusted to work at a resolution of 720P and a frame rate of 45FPS. If the target recognition type is a person, then the camera module 31 will be adjusted to work at a resolution of 1080P and a frame rate of 60FPS.

[0082] When the vehicle is in an intelligent driving mode, the camera module 31 preferably records at a resolution of 720P and a frame rate of 45FPS. When a target recognition type is detected, such as a person or a vehicle approaching the vehicle, the camera module 31 is adjusted to work at a resolution of 1080P and a frame rate of 60FPS.

[0083] When the vehicle is in a low-speed driving mode, for example, when the vehicle is driving at a speed of less than 25KM / H, the camera module 31 can preferably work at a resolution of 720P and a frame rate of 45FPS. When a target recognition type is detected approaching the vehicle or within a preset distance range of the vehicle, the camera module 31 is adjusted to work at a resolution of 1080P and a frame rate of 60FPS.

[0084] When the vehicle is in a parking monitoring mode, ultrasonic radar or millimeter-wave radar is preferably used for detection. Detection is started every 2S or 3S to confirm whether there is an object approaching the vehicle. If there is no object approaching within 15 meters, the cameras around the vehicle body do not need to be turned on. If there is an object approaching the vehicle and the object is within 15 meters of the vehicle, such as a person or a vehicle in the front, only the front-view camera is turned on, and currently it only records at a resolution of 720P and a frame rate of 45FPS. If the object remains stationary (i.e., in a static state) within 3 meters of the vehicle, the camera module 31 is adjusted to work at a resolution of 1080P and a frame rate of 60FPS. After the object is completely stationary, it is adjusted to work at a resolution of 720P and a frame rate of 45FPS.

[0085] The embodiment of the present application can effectively solve the heat dissipation problem of the camera module 31, while avoiding negative impacts on the energy consumption and performance of the vehicle, and also reducing the cost pressure on vehicle manufacturers.

[0086] In addition, the controller 32 can be a controller unit corresponding to the camera module 31 one by one, or it can be the vehicle controller or domain controller of the vehicle. The controller 32 can include but is not limited to a processor 401 and a memory 402. Those skilled in the art can understand that Figure 4 This is only an example of the controller 32 and does not constitute a limitation on the controller 32. It can include more or fewer components than shown in the figure, or different components.

[0088] The memory 402 can be an internal storage unit of the controller 32. For example, the hard disk or memory of the controller 32. The memory 402 can also be an external storage device of the controller 32. For example, a plug-in hard disk equipped on the controller 32, a Smart Media Card (SMC), a Secure Digital (SD) card, a Flash Card, etc. The memory 402 can also include both an internal storage unit of the controller 32 and an external storage device. The memory 402 is used to store computer programs and other programs and data required by the controller 32.
