[0002] With the development and popularization of intelligent driving functions, it is a common solution to place a high-definition camera in the upper area inside the front windshield to collect road condition information. In order to ensure that the camera area meets the requirements of clear vision and no stray light / dust, the camera area needs to be sealed as much as possible. However, due to the difference in temperature environment inside and outside the car, the camera area cannot avoid fogging, and the relatively sealed environment means that once the camera field of view is fogged, the fog will not dissipate, thus affecting driving safety.

[0003] In the related technology, a heating wire is usually added to the front camera field of view to dissipate fog. However, after the vehicle is powered on, the heating wire in the front camera field of view is kept in a heated state for a long time, which not only wastes energy, but also inevitably accelerates the aging of other components installed in this area, and increases the risk of cracking the front windshield.

[0004] Therefore, there is an urgent need for a camera defog method that can meet the defogging requirements while avoiding the long-term operation of the camera heating wire. Summary of the invention

[0010] Determine whether the camera area of ​​the vehicle is fogged based on the dew point temperature inside the vehicle and the temperature outside the vehicle;

[0011] When it is determined that the camera area of ​​the vehicle is fogged, the sealing area is controlled to be heated to defog the camera area of ​​the vehicle.

Their purpose is only to illustrate the feasibility of the implementation of the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0035] In order to solve the problems of the prior art, an embodiment of the present application provides a camera defog method, which can be applied in scenarios where a camera is arranged in the upper inner area of ​​the front windshield of a vehicle to collect road condition information, and the camera area is prone to fogging due to sealing. Figure 1 is a flow chart of a camera defogging method according to an embodiment of the present invention. Figure 1 As shown, the camera defogging method may include the following steps:

[0036] S110, monitoring whether the imaging clarity of a vehicle camera is less than a first threshold, wherein the vehicle camera is disposed in a sealing area of ​​a front windshield of the vehicle.

[0037] In S110, the vehicle may be a motor vehicle or non-motor vehicle with a heating function in the front camera area. During normal operation of the vehicle camera, one or more frames of image data may be obtained from the camera to detect the imaging clarity of the vehicle camera. The detection of imaging clarity may use edge detection, frequency domain analysis, gradient-based evaluation, etc., without limitation. The first threshold may be set according to the function and application scenario of the vehicle camera. For example, when the function execution of the vehicle camera requires a higher imaging clarity, the first threshold is larger.

[0038] In this way, by real-time detection of the vehicle camera imaging clarity and comparing it with the first threshold, it is ensured that the camera clarity meets the requirements, while reducing misjudgments caused by blurred imaging, thereby improving the safety and reliability of vehicle intelligent driving.

[0039] S120, when it is monitored that the imaging clarity of the vehicle camera is less than a first threshold, obtaining the vehicle's interior environment data and exterior temperature data, where the vehicle's interior environment data includes interior humidity data and interior temperature data.

[0040] In S120, when it is monitored that the imaging clarity of the vehicle camera is less than the first threshold, there are many reasons for the low imaging clarity of the vehicle camera, including that the vehicle camera is dirty, damaged, fogged, and the lighting conditions are poor. In order to quickly determine the reason for the low imaging clarity of the vehicle camera, the vehicle's in-vehicle environment data and outdoor temperature data can be first obtained to determine whether the low imaging clarity of the vehicle camera is caused by high humidity in the vehicle or a large temperature difference between the inside and outside of the vehicle.

[0041] Among them, the in-vehicle environmental data can be collected by sensor components such as temperature sensors and humidity sensors installed in the vehicle. It is understandable that if the in-vehicle temperature sensors, humidity sensors and other sensor components are not installed in the sealed area of ​​the vehicle's front windshield where the camera is located, the environmental data of the sealed area may be different from the in-vehicle environmental data. In order to reduce the deviation between the environmental data of the sealed area and the in-vehicle environmental data in this case, the sensor component can be set at a place close to the sealed area. For example, the sensor component can be set on the vehicle's front windshield.

[0042] In this way, by timely acquiring the in-vehicle environment data and the outside-vehicle temperature data, it is helpful to quickly locate the cause of the low imaging clarity of the vehicle camera and take corresponding measures to restore the normal imaging capability of the vehicle camera.

[0043] S130, calculating the in-vehicle dew point temperature according to the in-vehicle humidity data and the in-vehicle temperature data.

[0044] In S130, the in-vehicle dew point temperature is a function of the in-vehicle air humidity and the in-vehicle temperature. The dew point temperature may be calculated by using an existing meteorological library, for example, the metpy library in the python programming language. The calculation method of the in-vehicle dew point temperature is not limited herein.

[0045] S140, determining whether a camera area of ​​the vehicle is fogged based on the dew point temperature inside the vehicle and the temperature outside the vehicle.

[0046] In S140, the in-vehicle dew point temperature is the temperature of the air in the vehicle when it is cooled to saturation under the condition that the water vapor content (in-vehicle air humidity) and air pressure do not change. When the in-vehicle temperature is higher than the in-vehicle dew point temperature, the water vapor in the air will not condense into liquid water; when the in-vehicle temperature is lower than or equal to the in-vehicle dew point temperature and there is a temperature difference between the inside and outside of the vehicle, the water vapor in the vehicle will condense into fog on the colder surface (such as the glass in the camera area).

[0047] It is understandable that if the dew point temperature inside the car is higher than the outside temperature and there is a large temperature difference between the two, the glass surface in the camera area is likely to fog due to condensation of water vapor inside the car. If the dew point temperature inside the car is lower than or equal to the outside temperature, or the temperature difference between the two is small, the risk of fogging is relatively low.

[0048] Therefore, based on the dew point temperature inside the vehicle and the outside temperature data, it can be determined whether the camera area of ​​the vehicle is fogged.

[0049] S150, when it is determined that the camera area of ​​the vehicle is fogged, controlling the sealing area to be heated to defog the camera area of ​​the vehicle.

[0050] In S150, a heating wire may be provided in the sealing area to heat and defog the camera area of ​​the vehicle.

[0051] In the embodiment of the present application, by monitoring the imaging clarity of the vehicle camera and collecting the in-vehicle environment data and the outside temperature data when the imaging clarity is detected to be lower than a preset threshold, it can be understood that these data can be used to accurately calculate the in-vehicle dew point temperature, and then accurately determine whether the camera area is fogged. In the case where it is determined that the camera area of ​​the vehicle is fogged, the camera area of ​​the vehicle is controlled to be heated to defog the camera area of ​​the vehicle. In this way, not only can the camera area of ​​the vehicle be defogged, but also the energy waste and potential damage caused by the camera area being in a heated state for a long time can be avoided.

[0052] In some embodiments, determining whether a camera area of ​​a vehicle is fogged based on the dew point temperature inside the vehicle and the temperature outside the vehicle includes:

[0053] Calculate the difference between the dew point temperature inside the vehicle and the temperature outside the vehicle;

[0054] When the difference is less than or equal to the second threshold, determining that the camera area of ​​the vehicle is fogged;

[0055] When the difference is greater than the second threshold, it is determined whether the camera area of ​​the vehicle is fogged according to the interior lighting data, where the interior environment data includes the interior lighting data.

[0056] In one example, the dew point temperature in the car is Tdp and the outside temperature T out The difference between them is ΔT = T dp -T out When comparing the difference value with the second threshold value, the absolute value of the difference value may be used for comparison.

[0057] In this embodiment, the second threshold value can be set according to whether the camera area is prone to fogging. Specifically, the second threshold value can be determined by conducting experiments on fogging of the vehicle camera area for multiple times under different difference values.

[0058] In this embodiment, since the second threshold is a set value, when the difference is greater than the second threshold, the camera area of ​​the vehicle may also be fogged. Therefore, whether the camera area of ​​the vehicle is fogged can be further determined based on the interior lighting data.

[0059] In this way, by calculating the difference between the dew point temperature inside the vehicle and the temperature data outside the vehicle, it is possible to determine whether the camera area of ​​the vehicle is fogged, thereby achieving precise control of the heating of the camera area of ​​the vehicle.

[0060] In some embodiments, determining whether a camera area of ​​a vehicle is fogged according to the interior illumination data of the vehicle includes:

[0061] When the illumination data inside the vehicle is greater than a third threshold, determining that a camera area of ​​the vehicle is fogged;

[0062] When the interior illumination data is less than or equal to the third threshold, it is determined that the camera area of ​​the vehicle is not fogged.

[0063] In this embodiment, the third threshold can be set according to the minimum light intensity required for the imaging clarity of the vehicle camera at the first threshold, that is, when the in-vehicle lighting data is less than or equal to the third threshold, the imaging clarity of the vehicle camera is less than the first threshold.

[0064] In this embodiment, under the premise of excluding the fault of the vehicle's camera itself, when the illumination data inside the vehicle is greater than the third threshold, it can be explained that the vehicle's camera is not caused by the ambient light being too dark, resulting in the imaging clarity of the vehicle's camera being less than the first threshold. Therefore, it can be determined that the camera area of ​​the vehicle is fogged;

[0065] In this embodiment, when the in-vehicle lighting data is less than or equal to the third threshold, it is impossible to determine whether the vehicle's camera area is foggy because the ambient light is too dark, resulting in the vehicle's camera imaging clarity being less than the first threshold. Therefore, it is impossible to determine whether the vehicle's camera area is foggy. In this case, this solution determines that the vehicle's camera area is not foggy. It is understandable that in this case, even if the vehicle's camera area is determined to be foggy, it is impossible to defog the vehicle's camera area so that the imaging clarity of the vehicle's camera area is greater than or equal to the first threshold.

[0066] In this way, by comparing the interior lighting data with the third threshold, it is possible to effectively determine whether the vehicle camera area is fogged, providing an accurate basis for defogger measures, while avoiding misjudgment of unclear imaging caused by ambient light.

[0067] In some embodiments, after controlling the sealing area to heat to defog the camera area of ​​the vehicle when it is determined that the camera area of ​​the vehicle is fogged, the method further includes:

[0068] After a preset time, the sealing area is controlled to stop heating.

[0069] In this embodiment, the camera area of ​​the vehicle can be heated based on a preset time period, and the preset time period can be determined according to the past defog time; for example, the preset time period can be 15 minutes.

[0070] If the camera area of ​​the vehicle is already in a heating state when the camera area of ​​the vehicle is controlled to be heated, the camera area of ​​the vehicle can be controlled to stop heating after the current preset time period is executed. If the camera area of ​​the vehicle is not yet in a heating state when the camera area of ​​the vehicle is controlled to be heated, the camera area of ​​the vehicle can be controlled to stop heating after the preset heating time period.

[0071] In this way, by controlling the heating and defog time of the vehicle camera area, the fog can be effectively removed, and the energy waste and potential damage caused by long-term heating can be avoided, thereby improving the defog efficiency.

[0072] In some embodiments, after controlling the sealing area to heat to defog the camera area of ​​the vehicle when it is determined that the camera area of ​​the vehicle is fogged, the method further includes:

[0073] When it is detected that the camera area of ​​the vehicle is not fogged, the sealing area is controlled to stop heating.

[0074] In this embodiment, when it is monitored that the camera area of ​​the vehicle is not fogged, in order to avoid the camera area of ​​the vehicle being in a heating state for a long time after the vehicle is powered on, thereby wasting energy and accelerating the aging of other components installed in this area, the camera area of ​​the vehicle can be controlled to stop heating.

[0075] In this way, heating can be controlled by real-time monitoring of whether the camera area is fogged, and unnecessary heating can be stopped in time, which effectively saves energy, reduces the aging effects on other components, and improves the vehicle's energy efficiency and life.

[0076] In some embodiments, the method further comprises:

[0077] Monitor whether the vehicle air conditioner is in defog mode or whether the vehicle wipers are activated;

[0078] When it is detected that the vehicle air conditioner is in defog mode or the vehicle wipers are started, the sealed area is controlled to be heated to defog the camera area of ​​the vehicle.

[0079] In this embodiment, the following control logic may be used to control the camera area heating of the vehicle:

[0080] For example, if the vehicle wiper is turned on, the camera area of ​​the vehicle can be controlled to be heated. If the vehicle wiper is turned off, the camera area of ​​the vehicle can be controlled to stop heating. That is, the camera area heating caused by the vehicle wiper is synchronized with the state of the vehicle wiper. However, during the heating of the camera area caused by the vehicle wiper, the camera area is also triggered by other control logics for heating, then the camera area heating does not need to be synchronized with the state of the vehicle wiper. Other control logics can be for detecting that the vehicle air conditioner is in defog mode or that the camera area of ​​the vehicle is fogged.

[0081] Figure 2 FIG. 1 is a schematic diagram of a process of controlling camera area heating by a body control module according to an embodiment of the present invention. Figure 2 As shown, including:

[0082] S201, when the vehicle enters the air conditioning mode, the wiper mode or the camera area is judged to be fogged, sending control information to the body control module of the vehicle, the control information can be used to control the heating of the front windshield camera area;

[0083] In this embodiment, the air conditioning mode can be a defrost mode, including a front defrost mode and a rear defrost mode; the wiper mode can be achieved by controlling the working state of the wiper motor to turn the wiper on, off and operate at different speeds; the body control module can be an electronic control unit in a car for controlling various body functions of the vehicle.

[0084] S202, after receiving the control information, the body control module controls the heating of the front windshield camera area according to the control information.

[0085] In this embodiment, the body control module can coordinate and manage various systems and devices inside the vehicle through signals to ensure the normal operation of the vehicle and the safety and comfort of the driver.

[0086] Figure 3 is a schematic diagram of an overall flow of heating control of a camera area according to an embodiment of the present invention. Figure 3 As shown, the heating control method of the camera area may include the following steps:

[0087] S301, determine whether the air conditioning mode is switched to the front defrost mode, if so, execute S307.

[0088] S302, determine whether the vehicle wiper is turned on, if so, execute S305 and S306.

[0089] S303, determine whether the air conditioning mode is switched to the post-defrost mode, if so, execute S307.

[0090] S304, determine whether the camera area is fogged, if so, execute S307.

[0091] S305, determine whether the vehicle's manual wiper is turned on, if so, execute S307.

[0092] S306, determine whether the vehicle's automatic wiper is turned on, if so, execute S307.

[0093] S307, detect whether the camera area is in a heating state, if so, execute S308, otherwise execute S309.

[0094] S308, continue the current heating cycle.

[0095] S309, start camera area heating.

[0096] S310, turns off after heating for fifteen minutes.

[0097] In this way, the vehicle's driving conditions (such as defrost mode, wiper status) and the fogging of the camera area can be intelligently judged in a variety of ways, and the camera area heating can be automatically started and stopped to ensure a clear field of view while avoiding unnecessary energy consumption, thereby achieving intelligent and energy-saving heating control.

[0098] To facilitate understanding of the above solution, a complete embodiment will be provided below to illustrate how to determine whether the camera area is fogged.

[0099] Figure 4is a schematic diagram of a process for determining whether a camera area is fogged according to an embodiment of the present invention. Figure 4 As shown, the method may include the following steps:

[0100] S401, determine whether the imaging clarity of the vehicle camera is clear, if not, execute S402.

[0101] In this embodiment, when the imaging clarity of the vehicle camera is less than a first threshold, it is determined that the imaging of the vehicle camera is blurred.
