[0021] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0022] To facilitate understanding by those skilled in the art, the present application describes the specific implementation process of the technical solution provided by the present application through the following embodiments.

[0023] See also Figure 1The present application provides a self-checking and cleaning device for a vehicle-mounted assisted driving camera, comprising: a housing 3, a lens 1, a heating coil 8, a cleaning component and a controller; the lens 1 is mounted on the housing 3, and a portion of the lens 1 extends to the outside of the housing 3; the heating coil 8 is mounted on the structure where the lens 1 is located outside the housing 3, and the cleaning component is arranged on the side where the lens 1 is located outside the housing 3, the positions of the cleaning component and the heating coil 8 on the housing 3 do not interfere with each other, and the heating coil 8 and the cleaning component are both electrically connected to the controller; in the present application, the image obtained by the vehicle-mounted assisted driving camera is analyzed by the controller to confirm whether the lens 1 is dirty or not. Whether there is dirt, when there is steam mist on the lens 1, the controller can control the heating coil 8 to heat the lens 1 to remove the steam mist, and when there is dirt such as dust or mud on the lens 1, the controller can control the cleaning component to clean the dirt on the lens 1 to ensure the clarity of the lens 1; therefore, in the present application, the dirt condition of the vehicle-mounted assisted driving camera can be automatically confirmed, and after the dirt condition is confirmed, the heating coil 8 or the cleaning component can be used to automatically remove stains from the lens 1 without manual operation, thereby improving work efficiency and automation, and there is no need to stop the vehicle for operation, which is convenient to use.

[0024] Furthermore, an image sensor 2 is provided in the shell 3, and the image sensor 2 corresponds to the lens 1. When the vehicle-mounted assisted driving camera is working, the light of the observed area is captured by the lens 1 and projected to the image sensor 2. Then the image sensor 2 calculates and images the light projected by the lens 1, thereby completing the camera work and allowing the driver to understand the situation around the vehicle body according to the calculated image, and then perform corresponding driving operations.

[0025] Furthermore, the image sensor 2 is electrically connected to the controller, and the controller can receive the image of the image sensor 2 and compare and analyze the image to determine whether the lens 1 is dirty. The controller pre-stores a normal image of the lens 1, that is, an image when the lens 1 is not dirty. During operation, the controller compares and analyzes the real-time image transmitted by the image sensor 2 with the normal image, so that when the image clarity exceeds a certain level, it is determined that the lens 1 is dirty, and then the heating coil 8 or the cleaning component is activated to process the lens 1.

[0026] Specifically, the controller compares and analyzes the grayscale values ​​of the real-time image transmitted by the image sensor 2 with the normal image. When the grayscale value of a single position on the real-time image exceeds a certain range, it is assumed that there are dirty spots on the real-time image. Then, the positions of all dirty spots on the real-time image are located and the sizes are calculated according to the XY axis algorithm to obtain the area of ​​each dirty spot, and the dirty spots are judged to be regular or irregular in shape according to the area of ​​the dirty spots. When the dirty spots on the real-time image are regular in shape and the areas of all dirty spots reach the predetermined range of the real-time image, such as the dirt on the image is regular in shape and reaches more than 50% of the real-time image, it is judged that there is steam mist type dirt on the real-time image. At this time, the heating coil 8 is started to heat the lens 1 to remove the steam mist. When the real-time image is regular in shape and the area of ​​all dirty spots reaches the predetermined range of the real-time image, such as the dirt on the image is regular in shape and reaches more than 50% of the real-time image, it is judged that there is steam mist type dirt on the real-time image. At this time, the heating coil 8 is started to heat the lens 1 to remove the steam mist. When the dirt spots on the real-time image are irregular in shape and the area of ​​all the dirt spots reaches the predetermined range of the real-time image, such as when the dirt on the real-time image is irregularly scattered on the screen and has different shapes, and the total area of ​​the dirt reaches 10%, it is judged that there is mud spot type dirt on the real-time image, and the ultrasonic generator 9 of the cleaning component is started at this time, and the lens 1 is vibrated by the ultrasonic generator 9 to remove the mud spots on the lens 1; when there are both regular shaped dirt spots and irregular shaped dirt spots on the real-time image, and the area of ​​the two types of dirt spots reaches a predetermined range, such as when the area of ​​vapor mist dirt reaches more than 50% of the overall real-time image, and the mud spot type dirt reaches more than 50% of the overall real-time image, the water pump of the cleaning component is started to clean the camera lens.

[0027] Furthermore, the cleaning component includes an ultrasonic generator 9, which is arranged on a side of the lens 1 located outside the shell 3, and the ultrasonic generator 9 is electrically connected to the controller, and the position of the ultrasonic generator 9 on the shell 3 does not interfere with the heating coil 8 and the cleaning component; wherein, the operation of the ultrasonic generator 9 is controlled by the controller, so that the ultrasonic generator 9 emits ultrasonic waves and acts on the lens 1, thereby performing ultrasonic vibration on the lens 1, thereby shattering the mud spots on the lens 1 and making the mud spots separate from the lens 1, and finally achieving the purpose of cleaning the lens 1.

[0028] Furthermore, the heating coil 8 and the ultrasonic generator 9 are both ring-shaped and are mounted on the structure of the lens 1 outside the housing 3. The heating coil 8 is used to heat the lens 1 when there is steam mist, so as to make the steam mist evaporate quickly and reduce the steam mist from condensing into new steam mist on the lens 1; and the ultrasonic generator 9 is used to clean the lens 1 when there is mud spots on it.

[0029] Furthermore, the cleaning component includes a water pump, a water pipe and a nozzle, one end of the water pipe is connected to the water pump, and the other end is connected to the nozzle, the nozzle is installed on the frame and located on the side of the lens 1, and the water pump is electrically connected to the controller. The controller controls the operation of the water pump, and the water pump is used to draw water in and transport it to the nozzle through the water pipe, and spray it onto the lens 1 through the nozzle, so as to clean the stains on the lens 1, thereby ensuring the clarity of the lens 1. Specifically, when the heating coil 8 and the ultrasonic generator 9 cannot achieve the cleaning effect, the water pump is started to spray liquid to clean the auxiliary driving camera, and when the nozzle is cleaned, if there is still steam mist on the lens 1, the heating coil 8 can be controlled to clean the steam mist; and if there is still a small amount of mud and dirt remaining, the ultrasonic generator 9 can be started again to clean the mud and dirt on the lens 1.

[0030] It is worth noting that the heating coil 8, ultrasonic generator 9, water pump and nozzle all adopt the existing technology, and their structures can refer to the products disclosed in the existing technology, which will not be repeated here.

[0031] Furthermore, the controller includes a first control module 5, a second control module 6 and a third control module 7. The first control module 5 is electrically connected to the heating coil 8 for controlling the operation of the heating coil 8; the second control module 6 is electrically connected to the ultrasonic generator 9 for controlling the operation of the ultrasonic generator 9; the third control module 7 is electrically connected to the water pump for controlling the operation of the water pump.

[0032] Furthermore, a temperature sensor is provided on the housing 3, and the temperature sensor is located on the side of the heating coil 8 and is used to monitor the temperature of the heating coil 8. The temperature sensor is electrically connected to the controller. The temperature sensor is mainly used to monitor the temperature of the heating coil 8, so that the heating temperature of the heating coil 8 on the lens 1 is stabilized within a certain range, to prevent the lens 1 from being damaged due to excessive temperature, and when the temperature exceeds a preset value, the temperature sensor will transmit the temperature information to the controller, and then the controller will shut down the heating coil 8, so as to control the temperature within a suitable range.

[0033] Furthermore, it also includes a vehicle system 4, which has a central control display screen, and the central control display screen is electrically connected to the controller, wherein the controller can transmit the dirt condition of the lens 1 and the image of the image sensor 2 to the central control display screen for display, so that the driver can perform corresponding auxiliary operations according to the displayed information when necessary.

[0034] Furthermore, a circuit board is provided in the shell 3, and the circuit board is located on the side of the image sensor 2 away from the lens 1, and the circuit board is electrically connected to the image sensor 2 and the controller; wherein the circuit board is used to connect to an external power supply, thereby increasing the power supply for each component in the shell 3 and performing signal transmission.

[0035] Compared with the prior art: the vehicle-mounted assisted driving camera dirt self-detection and cleaning device of the present application includes: a shell 3, a lens 1, a heating coil 8, a cleaning component and a controller; the lens 1 is installed on the shell 3, and a part of the structure of the lens 1 extends to the outside of the shell 3; the heating coil 8 is installed on the structure of the lens 1 located outside the shell 3, and the cleaning component is arranged on the side of the lens 1 located outside the shell 3, and the heating coil 8 and the cleaning component are both electrically connected to the controller; specifically, a normal image of the lens 1 is pre-stored in the controller. When working, the controller compares and analyzes the grayscale value of the real-time image transmitted by the image sensor 2 in the lens 1 with the normal image. When the grayscale value of a single position on the real-time image exceeds a certain range, it is assumed that there are dirty spots on the real-time image. Then, the positions of all dirty spots on the real-time image are located and the sizes are calculated according to the XY axis algorithm. The area of ​​each dirt spot is obtained, and the dirt spot is judged to be regular or irregular in shape according to the area of ​​the dirt spot. When the dirt spot on the real-time image is regular in shape and the area of ​​all the dirt spots reaches the predetermined range of the real-time image, it is judged that there is mist type dirt on the real-time image, and the heating coil 8 is started to heat the lens 1 to remove the mist; when the dirt spot on the real-time image is irregular in shape and the area of ​​all the dirt spots reaches the predetermined range of the real-time image, it is judged that there is mud spot type dirt on the real-time image, and the ultrasonic generator 9 of the cleaning component is started to vibrate the lens 1 through the ultrasonic generator 9 to remove the mud spots on the lens 1; when there are both regular shaped dirt spots and irregular shaped dirt spots on the real-time image, and the area of ​​the two types of dirt spots reaches the predetermined range, the water pump of the cleaning component is started to clean the camera lens.

[0036] Therefore, in the present application, the image acquired by the vehicle-mounted assisted driving camera is analyzed by the controller to confirm whether there is dirt on the lens 1. When there is steam mist on the lens 1, the heating coil 8 can be controlled by the controller to heat the lens 1 to remove the steam mist. When there is dirt such as dust or mud spots on the lens 1, the cleaning component can be controlled by the controller to clean the dirt on the lens 1 to ensure the clarity of the lens 1. Therefore, in the present application, the dirt condition of the vehicle-mounted assisted driving camera can be automatically confirmed, and after confirming the dirt condition, the stains can be automatically removed by the heating coil 8 or the cleaning component without manual operation, thereby improving work efficiency and automation, and there is no need to stop the car for operation, which is convenient to use.
