As shown in fig. 1, the headlamp adaptive high beam control architecture in the related art includes a camera, a camera ECU, a light control system, a vehicle control system, a light source drive, and a headlamp. Referring to the principle of the ADB function as described above, when a light control system controls a light source to drive and execute a light strategy for automatically shielding a high beam light beam to form a shadow area, the shadow area is too large and inaccurate in self-adaptive high beam due to too low pixels of a high beam module contained in a headlight, so that a high-precision shadow area cannot be realized, and the advantage of the self-adaptive function is reflected; and because the quantity of light sources such as LEDs in the headlight is limited, adjacent pixels are spliced to cause black shadows between the two, so that the range of a shadow area is larger, the visual range of a user is influenced, and the driving safety of the user is influenced.

As shown in fig. 2 and 3, in the headlight light area, the shadow area formed by the related art is larger, and the adjacent pixels are spliced to cause a black shadow therebetween, which affects the visual range of the user.
In addition, the application of projectors on automobiles is made possible by the increasing entertainment functions with the intelligent popularization and application of automobiles. However, the working environment of the household projector is better, the working condition is complex on the vehicle, the requirements on vibration resistance, high temperature, water resistance, dust resistance, weather resistance and the like are very high, and the requirements on the light source, the chip and the like are very firm, so that the requirements of the vehicle-mounted projector on the light source and the chip and the like are much higher than those of the household projector and the office projector, and the technical scheme with high maturity and good stability is needed to be adopted.
Vehicle-mounted projectors, particularly external vehicle-mounted projectors, are required to project application scenes such as outdoor places such as outing and camping. Besides the conventional projection function, the external vehicle-mounted projector has millions of pixels and very high brightness, can partially or completely meet the high-low beam function of the vehicle, and can realize the AFS function of a headlight of the vehicle, such as the self-adaptive high beam ADB function, according to the condition of the road vehicle.
Therefore, in order to solve the above-mentioned problems, the embodiment of the present application provides a vehicle light control scheme, by acquiring related data of a front object and driving parameters of a vehicle, determining a dark area attribute matched with the front object, and using the characteristics of high pixels of a vehicle projector such as a laser projector, the vehicle projector is controlled to project a white screen, and under the working scenes such as meeting, following, etc., a dark area is formed in the area of the front object, so that the formed dark area range is more accurate, the problems of overlarge self-adaptive high beam shadow area of a headlight in the current market, etc., are effectively solved, the influence on the visual range of a user is reduced, and thus the driving safety of the user is effectively and greatly improved.

Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 4 is a schematic flow chart of a vehicle light control method according to an exemplary embodiment of the application.
As shown in fig. 4, the vehicle light control method includes the steps of:
s401, acquiring image information in front of a vehicle.
Fig. 5 is a schematic diagram of a projector adaptive high beam control architecture according to an exemplary embodiment of the present application. As shown in fig. 5, the projector adaptive high beam control architecture includes an image acquisition device, an image acquisition device ECU, a light control system, a vehicle control system, a projector drive, and a projector, wherein the projector is operable to implement a headlight illumination function of a vehicle.
In the architecture shown in fig. 5, the vehicle control system collects image information in front of the vehicle through the image collection device, and the image information may include, but is not limited to, video or picture, based on which the condition of the road surface facing or co-rotating front object can be determined.
Alternatively, the image acquisition device may be a camera or an infrared lidar or the like. The conventional camera can identify the vehicle by detecting the light of the vehicle at night, but cannot identify non-luminous objects such as human bodies or animals; the infrared laser radar can be used for identifying non-luminous objects such as people, animals and the like besides identifying the vehicle by detecting the light of the vehicle.
S402, based on the image information, related data of the front object is determined, the related data including a size, a position, and a moving speed.
Still referring to fig. 5, in this step, the vehicle control system may preprocess the image information acquired by the image acquisition apparatus using the image acquisition apparatus ECU, and then determine the related data of the front object, such as the size of the front object, the position of the front object, the moving speed of the front object, and the like, based on the image preprocessing result; the relevant data is then sent to the lighting control system. It should be clear that the preprocessing is an optional step, i.e. the image information is not preprocessed, and the related data of the front object is directly determined.
Illustratively, preprocessing includes image denoising, image registration, image measurement, and the like. The image denoising can be realized through a filtering technology, and common filtering methods include mean filtering, median filtering and the like, so as to reduce noise in image information; image registration refers to aligning images at different moments so as to measure the position and the speed of a target object, and optionally, the image registration method comprises correlation matching, template matching and the like; image measurement refers to measuring pixel values of a target object for obtaining size and position information of the target object, and optionally, the measurement method includes a brightness threshold method, an edge detection method, and the like.
S403, determining dark area attributes matched with the front object according to the driving parameters of the vehicle and related data, wherein the driving parameters comprise driving speed.
Correspondingly, acquiring related data of a front object sent by the ECU through a light control system, and acquiring the current running speed of the vehicle through a vehicle control system; according to the running speed and the size, position and moving speed of the front object, a preset rule is adopted to determine a lamplight strategy, the lamplight strategy comprises a dark area attribute, and the dark area attribute is matched with the size, position and moving speed of the front object, so that the dark area attribute is also changed in real time according to the running parameters of the vehicle and the related data of the front object in the process of relative movement of the vehicle and the front object, and the matching degree of the dark area attribute and the front object is improved.
S404, controlling the projector to throw a white screen based on the dark area attribute, and forming a dark area in the area of the front object.
Further, the lighting strategy is sent to the projector driver through the lighting control system, and the projector driver controls the projector to throw a white screen and form a dark area in the area of the front object based on the dark area attribute in the lighting strategy.
Fig. 6 is a schematic diagram of a projector adaptive high beam single-vehicle light effect provided by an exemplary embodiment of the present application, and fig. 7 is a schematic diagram of a projector adaptive high beam multi-vehicle light effect provided by an exemplary embodiment of the present application. As shown in fig. 6, when a bicycle is used, the projector projects a white screen, and a dark area matched with the size and the moving speed of the vehicle is formed at the position of the vehicle, and other areas have no black shadows. As shown in fig. 7, when a vehicle is multiple, the projector projects a white screen, and a dark area matching the size and the moving speed of the corresponding vehicle is formed at the position of each vehicle, and other areas have no shadow.
According to the vehicle light control method provided by the embodiment of the application, the dark area attribute matched with the front object is determined by combining the related data of the front object and the running parameters of the vehicle, so that the accuracy of the obtained dark area attribute is higher; in addition, the projector is controlled to project the white screen, and a dark area is formed in the area of the front object based on the dark area attribute, so that the formed dark area is more accurate in range, the influence on the visual range of the user is reduced, and the driving safety of the user is improved.
In some embodiments, the driving parameters further include yaw rate, the dark space properties include size, position, and speed of movement, and determining dark space properties that match the forward object based on the driving parameters of the vehicle and related data includes: determining the relative movement speed of the front object according to the movement speed of the front object and the running speed of the vehicle; determining a moving speed of the dark area according to the relative moving speed and position of the front object and the yaw rate of the vehicle; the size and position of the dark area are determined according to the size and position of the object in front.
For example, if the moving speed of the front object is V 1, the running speed of the vehicle is V 2, and the running directions of the front object and the vehicle are opposite, the relative moving speed V of the front object is the sum of V 1 and V 2; if the traveling directions of the front object and the vehicle are the same, the relative movement speed V of the front object is the difference between V 1 and V 2. Further, considering that the yaw rate of the vehicle is an important index for measuring the running stability of the vehicle, multiple factors such as tires, a suspension system, a steering system, a vehicle load, and a driver operation may cause yaw problems of the vehicle, because the embodiment of the application determines the moving speed of the dark area according to the relative moving speed and position of the front object and in combination with the yaw rate of the vehicle, the accuracy of the obtained moving speed of the dark area is higher; correspondingly, the size and the position of the dark area are determined according to the size and the position of the front object, namely the size of the dark area is consistent with the size of the front object, and the position of the dark area is consistent with the position of the front object.
In some embodiments, the front object may include one or more of the following: vehicles, humans and animals, and the like.
For example, if the front object is a human or animal, based on the image information, relevant data of the human or animal including a size, a position, and a moving speed are determined, dark area attributes matching the human or animal are determined according to a running parameter of the vehicle, and the relevant data of the human or animal, the projector is controlled to project a white screen based on the dark area attributes, and a dark area is formed in an area of the human or animal. Accordingly, by forming a dark area in the region of the person or animal, glare of the person or animal can be avoided.
In some embodiments, controlling the projector to project a white screen and form a dark area in an area of the front object based on the dark area attribute includes: controlling the projector to throw a white screen in a lamplight area of the vehicle; and controlling the projector to form a dark area consistent with the size and the position of the front object in the area of the front object according to the dark area attribute, wherein the dark area moves according to the moving speed.
For example, the projector is used for realizing a headlight illumination function of a vehicle, the projector emits high beam to realize night driving illumination of the vehicle, when the light control system sends a light strategy to the projector driver, the projector driver controls the projector to throw a white screen in a light area of the projector based on a dark area attribute in the light strategy, and controls the projector to form a dark area consistent with the size and the position of a front object in the area of the front object according to the dark area attribute, the dark area moves according to the moving speed, for example, the moving speed in the dark area attribute is V 0, and the dark area moves according to V 0; as shown in fig. 6 and 7, when the front object is a vehicle, the dark area size coincides with the front vehicle size.
In some embodiments, the related data further includes a number of objects, and the vehicle light control method further includes: the number of the objects in the front object is larger than or equal to a preset value, and the projector is controlled to be switched from high beam to low beam.
For example, when the number of objects of the front object is greater than or equal to a preset value, for example, the preset value is 10, if dark areas are formed in the area of each object, 10 dark areas will be formed in front of the vehicle, and interference may be caused to the sight of the user, so that the projector can be controlled to switch from high beam to low beam, so as to further ensure the driving safety of the user.
On the basis of the above embodiments, in some embodiments, controlling the projector to project a white screen in a light area of the vehicle includes: and controlling the projector to throw a white screen in a lamplight area of the vehicle to supplement light.
Fig. 8 is a schematic diagram of a headlamp+projector adaptive high beam control architecture according to an exemplary embodiment of the present application. As shown in fig. 8, the headlamp + projector adaptive high beam control architecture includes an image capture device, an image capture device ECU, a light control system, a vehicle control system, a light source drive, a headlamp, a projector drive, and a projector. Correspondingly, controlling the projector to throw a white screen in a lamplight area of the vehicle for light supplementing, and controlling the projector to form a dark area with the same size and position as those of the front object in the area of the front object according to the dark area attribute, wherein the dark area moves according to the moving speed. Accordingly, fig. 9 is a schematic diagram of headlight and projector adaptive high beam single-vehicle light efficiency according to an exemplary embodiment of the present application, and fig. 10 is a schematic diagram of headlight and projector adaptive high beam multi-vehicle light efficiency according to an exemplary embodiment of the present application. As shown in fig. 9, when a bicycle is used, the projector projects a white screen to supplement light to a light area of a headlight, and a dark area is formed at the position of the bicycle. As shown in fig. 10, when a plurality of vehicles are traveling, the projector projects a white screen to supplement the light area of the headlight, and a dark area is formed at the position of each vehicle. The white screen projected by the projector is overlapped to carry out light supplementing on the basis of the existing low-pixel self-adaptive high beam headlamp, so that a more accurate dark area range can be formed under lower cost, the influence on the visual range of a user is reduced, and the driving safety of the user is improved.
On the basis of the above embodiments, in some embodiments, the vehicle light control method further includes: determining that there is no front object in front of the vehicle based on the image information; and controlling the projector to project a white screen in a lamplight area of the vehicle.
For example, if there is no front object in front of the vehicle, i.e., no vehicle, person or animal, the light control system updates the light strategy and sends the updated light strategy to the projector driver. Correspondingly, in one implementation mode, the projector drive controls the projector to throw a white screen in a light area of the vehicle based on the updated light strategy, light is supplemented to the light area of the vehicle, and driving safety of a user is further improved through enhancing the intensity of light.
