[0038] Example 1

[0039] Figure 1 This is a flow chart of a vehicle information projection method provided in Example 1 of the present invention. This embodiment of the present invention is applicable to vehicle information projection scenarios. The method can be performed by a vehicle information projection device, which can be implemented in hardware and / or software and can be configured in a vehicle information projection device.

[0040] See also Figure 1 The vehicle information projection method shown includes:

[0041] S101: Obtain road condition satellite information and traffic satellite information on a target navigation route of a vehicle, as well as the real-time driving position of the vehicle.

[0042] The target navigation route can be used to describe the vehicle's route based on satellite information. Road condition satellite information can be used to describe road environment conditions along the target navigation route, as determined by satellite information. For example, road condition satellite information can include information about broken roads, flooded roads, sunken roads, and road obstructions. Traffic satellite information can be used to describe road traffic information along the target navigation route, as determined by satellite information. For example, traffic satellite information can include information about zebra crossing locations, road lights, road signs, and service areas. Real-time driving location can be used to describe the vehicle's real-time location along the target navigation route, as displayed by satellite information.

[0043] Specifically, the vehicle's starting point and destination are obtained, including but not limited to voice input or electronic device input, which is not limited in this embodiment of the present invention. Satellite data is obtained, and road condition satellite information and traffic satellite information on the vehicle's target navigation route are queried based on the satellite data. This can reduce the amount of satellite information obtained and the vehicle's real-time driving position, facilitate positioning the vehicle's driving position, and obtain road condition satellite information and traffic satellite information corresponding to the vehicle's real-time driving position.

[0044] In one example, a target navigation route of a vehicle is obtained from location A to location B. Satellite information is connected to obtain road condition satellite information indicating a puddle on the road between location A and location B, traffic satellite information indicating a zebra crossing on the road between location A and location B, and the real-time driving position of the vehicle is location A.

[0045] S102: Acquire the pre-display distance and information collection radius input by the user.

[0046] The pre-display distance can be used to describe the distance between the area where the pre-displayed traffic satellite information and traffic satellite information are displayed and the vehicle. The information collection radius can be used to describe the radius of a circle centered on the vehicle's real-time driving position when collecting traffic satellite information and traffic satellite information from the vehicle.

[0047] Specifically, the pre-display distance and information collection radius input by the user are obtained, and the acquisition methods include but are not limited to: user video data recognition, user voice input, or user input using a touch screen, etc., which are not limited in the embodiment of the present invention.

[0048] In one example, a camera captures the user's face to obtain video data of the user, and a voice acquisition device captures the user's voice data. By recognizing the user's video and voice data, the user's input pre-display distance is obtained as 100 meters, and the information collection radius is 5 meters.

[0049] S103 : Calculate the data collection area and data pre-collection area of ​​the vehicle according to the real-time driving position and information collection radius of the vehicle.

[0050] The data collection area can be used to describe a circular area centered on the vehicle's real-time driving position and with the information collection radius as its radius. The data pre-collection area can be used to describe a circular area centered on the vehicle's position and with the information collection radius as its radius within the pre-display distance.

[0051] Specifically, the center of the data collection area is determined based on the vehicle's real-time driving location. Based on the information collection radius, the vehicle's data collection area can be obtained using a circle area calculation formula. Based on the pre-displayed distance input by the user, a circle area centered on the vehicle's location and with the information collection radius as its radius can be calculated, representing the pre-collection area for vehicles in Huqiu. The vehicle can obtain satellite information on road conditions and traffic conditions around its real-time driving location, and can also pre-collect satellite information on road conditions and traffic conditions at the location the vehicle is about to travel to, as indicated in the pre-displayed example.

[0052] In one example, the vehicle's data collection area and pre-data collection area are calculated based on the vehicle's real-time location and information collection radius. The data collection area is calculated as a circle with the vehicle's real-time location as the center and the information collection radius as the radius. The user enters a pre-display distance of 100 meters. A location on the target route 100 meters from the vehicle's real-time location is obtained, set as the center, and the area within the circle with the information collection radius as the radius is determined as the pre-data collection area.

[0053] S104 , querying the road condition satellite information and traffic satellite information corresponding to the vehicle's data collection area based on the road condition satellite information and traffic satellite information on the vehicle's target navigation route, and determining the vehicle environment information of the vehicle.

[0054] The vehicle environment information of the vehicle may be used to describe a collection of road condition satellite information and traffic satellite information within the data collection area.

[0055] Specifically, based on the road condition satellite information and traffic satellite information on the vehicle's target navigation route, the road condition satellite information and traffic satellite information corresponding to the vehicle's data collection area are queried. The query method includes but is not limited to: depth-first traversal algorithm and breadth-first algorithm, etc. The embodiment of the present invention is not limited to this. The vehicle environment information of the vehicle is determined, the amount of vehicle environment information data is reduced, and the efficiency of vehicle information projection is improved.

[0056] In one example, based on the road condition satellite information and traffic satellite information on the target navigation route of the vehicle, the road condition satellite information and traffic satellite information corresponding to the vehicle's data collection area are queried through a depth-first traversal algorithm to determine the vehicle's vehicle environment information.

[0057] S105 , querying the road condition satellite information and traffic satellite information corresponding to the data pre-collection area located at the pre-display distance based on the road condition satellite information and traffic satellite information on the target navigation route of the vehicle, and determining the vehicle pre-display information of the vehicle.

[0058] The vehicle pre-display information may be used to describe a data pre-collection area at a pre-display distance from the real-time driving position of the vehicle, and a collection of road condition satellite information and traffic satellite information in the pre-display data pre-collection area.

[0059] Specifically, based on the road condition satellite information and traffic satellite information on the target navigation route of the vehicle, a data pre-collection area within the pre-display distance is queried. Based on the data pre-collection area, the road condition satellite information and traffic satellite information on the target navigation route of the vehicle are queried. The query method includes, but is not limited to, a sequential search algorithm, a binary search algorithm, or a hash table search algorithm, etc., which is not limited in this embodiment of the present invention. The road condition satellite information and traffic satellite information corresponding to the data pre-collection area are obtained to determine the vehicle's pre-display information.

[0060] In one example, based on the road condition satellite information and traffic satellite information on the target navigation route of the vehicle, the road condition satellite information and traffic satellite information corresponding to the data pre-collection area located at the pre-display distance are queried through a sequential search algorithm to determine the vehicle pre-display information of the vehicle.

[0061] S106 , filtering objects in the vehicle environment information and the vehicle pre-display information to obtain an object space position and an object size of at least one object to be displayed, and generating image information to be projected.

[0062] The object to be displayed can be used to describe an object to be projected that affects vehicle driving. The object's spatial position can be used to describe the coordinates of the object to be displayed relative to the vehicle's real-time driving position. The object's size can be used to describe the size of the object to be displayed, and the object's size parameter information corresponds to the shape of the object to be displayed. The image information to be projected can be used to describe the information to be projected and displayed to the user.

[0063] Specifically, objects in the vehicle environment information and vehicle pre-display information are screened, objects that affect vehicle driving are selected, and the object spatial position and object size of at least one object to be displayed are obtained. Information on objects that may affect vehicle driving can be obtained, and image information to be projected is generated, thereby improving the safety of vehicle driving.

[0064] In one example, objects in the vehicle environment information and the vehicle pre-display information are screened, and it is found that the object to be displayed is a road pothole. The object spatial position of the road pothole is 10 meters directly in front of the vehicle, and the object size of the road pothole is a circle with a radius of 0.5 meters, thereby generating image information to be projected.

[0065] S107: Projecting the image information to be projected through the holographic projection vehicle light.

[0066] Among them, holographic projection headlights can be used to describe headlights with medium-free projection functions.

[0067] Specifically, the image information to be projected can be projected through holographic projection headlights. Users can obtain information on the road from multiple perspectives without changing their driving posture. They can also project the image information displayed on the vehicle's central control display screen as needed, thereby improving driving safety.

[0068] In one example, Figure 2 The figure shows a schematic diagram of the vehicle information projection structure, 101 can be a signal receiver, 102 can be a holographic projection headlight, the signal receiver can receive the image information to be projected, and send the image information to be projected to the holographic projection headlight, and the image information to be projected is projected through the holographic projection headlight.

[0069] The technical solution of the embodiments of the present invention obtains road condition satellite information and traffic satellite information along the vehicle's target navigation route, as well as the vehicle's real-time driving position, and calculates the vehicle's data collection area and data pre-collection area based on the information collection radius. This allows the area of ​​the vehicle's real-time projected data to be adjusted according to user needs. The vehicle's data collection area is queried for road condition satellite information and traffic satellite information to determine the vehicle's surrounding information, filtering it to the user's desired projection area, thereby improving driving safety. The vehicle's data pre-collection area is queried for road condition satellite information and traffic satellite information to determine the vehicle's pre-display information. This pre-display information can be retrieved in advance, facilitating data pre-display and providing users with advance information about the road environment, thereby improving driving safety. Objects in the vehicle's surrounding information and pre-display information are filtered to determine the spatial position and size of at least one object to be displayed, generating image information to be projected, and projecting the image information using holographic projection headlights. This reduces the amount of displayed data and improves vehicle information projection efficiency.

[0070] Optionally, after filtering objects in the vehicle environment information and the vehicle pre-display information, obtaining the object spatial position and object size of at least one object to be displayed, and generating the image information to be projected, it also includes: performing real-time anomaly monitoring of the vehicle equipment operating data of the vehicle according to preset equipment operating conditions to obtain vehicle equipment fault data; performing signal monitoring on the vehicle's data collection area and data pre-collection area to obtain the vehicle's adjacent vehicle distress data; querying the fault identifier corresponding to the vehicle equipment fault data and the distress identifier corresponding to the adjacent vehicle distress data based on the vehicle equipment fault data and the adjacent vehicle distress data; generating emergency image information to be projected based on the fault identifier corresponding to the vehicle equipment fault data and the distress identifier corresponding to the adjacent vehicle distress data; and updating the image information to be projected to emergency image information to be projected.

[0071] Among them, the preset equipment operating conditions can be preset conditions for determining whether the vehicle is faulty. The vehicle equipment can be equipment that enables the vehicle to operate normally. The operating data can be used to describe the data obtained by monitoring the operating status of the vehicle equipment. Real-time abnormality monitoring can be used to describe the operation of real-time monitoring of the operating data of the vehicle equipment. The vehicle equipment fault data can be used to describe the data that causes faults in the operating data of the vehicle equipment. Signal monitoring can be used to describe the operation of the vehicle receiving and monitoring signals. The adjacent vehicle distress data can be used to describe the distress signals sent by vehicles located in the data collection area or data pre-collection area of ​​the vehicle. The fault identifier can be used to describe the identifier that uniquely identifies the vehicle equipment fault. The distress identifier can be used to describe the identifier that uniquely identifies the distress signal. The emergency image information to be projected can be used to describe the image information to be projected for priority emergency projection.

[0072] Specifically, the preset device operating conditions can be used to determine whether the operating data of a vehicle device is abnormal. Based on the preset device operating conditions, the operating data of at least one vehicle device of the vehicle is monitored for abnormalities in real time to obtain vehicle device fault data. Signal monitoring within the vehicle's data collection area and pre-data collection area can be performed to obtain distress data from neighboring vehicles, as well as distress information from vehicles within the area where the vehicle can receive distress signals, enabling timely assistance to other vehicles. Based on the vehicle device fault data and the distress data from neighboring vehicles, the fault identifier corresponding to the vehicle device fault data and the distress identifier corresponding to the distress data from neighboring vehicles are queried. Different faults correspond to different fault identifiers, and different distress signals correspond to different distress identifiers. This facilitates providing different assistance methods to other vehicles based on different faults or types of distress. Based on the fault identifier corresponding to the vehicle device fault data and the distress identifier corresponding to the distress data from neighboring vehicles, emergency image information to be projected is generated and updated to the emergency image information to be projected. Distress signals or fault information from vehicles in the vicinity of the vehicle are preferentially displayed, enabling timely response to various road conditions and improving vehicle driving safety.

[0073] In one example, the preset equipment operating condition is that all vehicle doors are closed. Based on the preset equipment operating condition, real-time abnormality monitoring of the vehicle's equipment operating data is performed, and vehicle equipment fault data is obtained, indicating that the cab door is not closed. Signal monitoring is performed on the vehicle's data collection area and data pre-collection area, and distress data from adjacent vehicles is obtained, indicating that vehicle 1 has a flat tire. Based on the vehicle equipment fault data and the adjacent vehicle distress data, the fault identifier a corresponding to the vehicle equipment fault data and the distress identifier b corresponding to the adjacent vehicle distress data are queried. Based on the fault identifier corresponding to the vehicle equipment fault data and the distress identifier corresponding to the adjacent vehicle distress data, emergency image information to be projected is generated, and the image information to be projected is updated to the emergency image information to be projected.

[0074] By conducting real-time abnormal monitoring of the operating data of the vehicle's vehicle equipment according to preset equipment operating conditions, the vehicle equipment fault data is obtained, the vehicle equipment operating status of the vehicle can be detected in time, the signal monitoring of the vehicle's data collection area and data pre-collection area is carried out, the vehicle's adjacent vehicle distress data is obtained, and the distress signals of surrounding vehicles are obtained in time. According to the vehicle equipment fault data and the adjacent vehicle distress data, the fault identifier corresponding to the vehicle equipment fault data and the distress identifier corresponding to the adjacent vehicle distress data are queried. According to the fault identifier corresponding to the vehicle equipment fault data and the distress identifier corresponding to the adjacent vehicle distress data, different operations are performed for different information to improve the processing efficiency of responding to various situations, generate emergency image information to be projected, update the image information to be projected to emergency image information to be projected, give priority to projecting the emergency image information to be projected, and obtain the vehicle's fault information and distress information in time, quickly prepare response measures, and improve the safety of vehicle driving.

[0075] Optionally, after obtaining the road condition satellite information and traffic satellite information on the vehicle's target navigation route, as well as the vehicle's real-time driving position, the process includes: obtaining the driver's behavior inside the vehicle; detecting whether the driver's behavior satisfies conditions for inability to drive normally; if the conditions for inability to drive normally are met, turning on the automatic driving mode; if the conditions for inability to drive normally are not met, not turning on the automatic driving mode.

[0076] Among them, vehicle internal driver behavior can be used to describe the real-time behavior of the driver driving the vehicle. Normal driving conditions can be used to describe the conditions under which the driver cannot normally and safely drive the vehicle. Automatic driving mode can be used to describe the mode in which the onboard computer controls the vehicle's driving.

[0077] Specifically, the driver's behavior within the vehicle is acquired, including but not limited to neural networks. The driver's behavior within the vehicle can be determined by acquiring the driver's facial expressions, the driver's actions, or the actions of passengers. The driver's behavior is tested to determine if it is safe based on abnormal driving conditions. If the abnormal driving conditions are met, the autonomous driving mode is activated. Examples include the driver's hands being off the steering wheel for an extended period, a passenger grabbing the steering wheel, or the driver suffering a sudden illness. If the abnormal driving conditions are not met, the autonomous driving mode is not activated.

[0078] In one example, by shooting a video of the driver and passengers inside a vehicle and identifying the video data, it is determined that the driver's behavior inside the vehicle is that the driver's hands are off the steering wheel for a long time. The driver's behavior is detected to meet the conditions for normal driving, and the automatic driving mode is turned on.

[0079] By obtaining the driver's behavior inside the vehicle, it is detected whether the driver's behavior meets the conditions for abnormal driving. If the conditions are met, the automatic driving mode is turned on. If the conditions are not met, the automatic driving mode is not turned on. The driving conditions inside the vehicle are monitored in real time to ensure the safety of vehicle driving.

[0080] Optionally, after projecting the image information to be projected through the holographic projection headlights, it also includes: obtaining a projection style modification command; analyzing the projection style modification command to obtain a projection ratio and a projection style; updating the image information to be projected according to the projection ratio and the projection style, and re-projecting the image information to be projected through the holographic projection headlights.

[0081] The projection style modification command can be used to describe a command for modifying the projection style of the projected image information. The projection ratio can be used to describe the ratio of the actual size of the projected image information to the initial size of the projected image information. The projection style can be used to describe the display style of the projected image information. Projection styles include, but are not limited to, the projection color of the projected image information, the display position of the projected image information, and the display order of the projected image information.

[0082] Specifically, obtaining a projection style modification command indicates that the user wishes to modify the display content of the projected image information. The projection style modification command is analyzed using methods including, but not limited to, neural networks or natural language processing, which are not limited in this embodiment of the present invention. A projection scale and projection style are obtained, and the projected image information is updated according to the projection scale and projection style. The projected image information is then re-projected using the holographic projection headlights. The re-projected image information is the image information processed by the projection style modification command.

[0083] In one example, a projection style modification command is obtained to modify the display color of the image information to be projected to blue and the projection ratio of the image information to be projected to 50%. The projection style modification command is processed by a neural network to obtain a projection ratio of 50% and a projection style of the image information to be projected, and the display color of the image information to be projected is blue. The image information to be projected is updated according to the projection ratio and projection style, and the image information to be projected is re-projected through the holographic projection headlights.

[0084] By obtaining the projection style modification command, analyzing the projection style modification command, obtaining the projection ratio and projection style, updating the projection image information according to the projection ratio and projection style, and re-projecting the image information to be projected through the holographic projection headlights, the projection image information can be modified according to user needs, can meet different projection needs, and improve the accuracy of the projection of the image information to be projected.

[0085] Example 2

[0086] Figure 3 This is a flow chart of a vehicle information projection method provided in the second embodiment of the present invention. Based on the above embodiments, this embodiment of the present invention optimizes and improves the vehicle information projection method.

[0087] Furthermore, “screening objects in the vehicle environment information and vehicle pre-display information to obtain the object spatial position and object size of at least one object to be displayed, and generating image information to be projected” is refined into “screening at least one object to be displayed corresponding to a target type among the objects in the vehicle environment information and vehicle pre-display information; target types include: environmental hazard type, vehicle operation hazard type and traffic sign type; obtaining the object spatial position and object size corresponding to each object to be displayed; calculating the actual distance between each object to be displayed and the vehicle based on the vehicle environment information and vehicle pre-display information, as well as the object spatial position of each object to be displayed; generating image information to be projected based on the actual distance between each object to be displayed and the vehicle and the object size of each object to be displayed”, so as to improve the vehicle information projection method.

[0088] It should be noted that for parts not described in detail in the embodiments of the present invention, reference may be made to the descriptions of other embodiments.

[0089] See also Figure 3 The vehicle information projection method shown includes:

[0090] S301: Obtain road condition satellite information and traffic satellite information on the target navigation route of the vehicle, as well as the real-time driving position of the vehicle.

[0091] S302: Acquire the pre-display distance and information collection radius input by the user.

[0092] S303: Calculate the data collection area and data pre-collection area of ​​the vehicle based on the real-time driving position and information collection radius of the vehicle.

[0093] S304 , querying the road condition satellite information and traffic satellite information corresponding to the data collection area of ​​the vehicle based on the road condition satellite information and traffic satellite information on the target navigation route of the vehicle, and determining the vehicle environment information of the vehicle.

[0094] S305 , querying the road condition satellite information and traffic satellite information corresponding to the data pre-collection area located at the pre-display distance based on the road condition satellite information and traffic satellite information on the target navigation route of the vehicle, and determining the vehicle pre-display information of the vehicle.

[0095] S306 , screening at least one to-be-displayed object corresponding to a target type from the objects in the vehicle environment information and the vehicle pre-display information; the target types include: environmental hazard type, vehicle operation hazard type, and traffic sign type.

[0096] Among them, target type can be used to describe the type of object that affects vehicle driving. Environmental hazard type can be used to describe the type of object that causes danger in the vehicle driving environment, for example, road puddles, road depressions, road breaks, or rocks blocking the road. Vehicle operation hazard type can be used to describe the type of object that causes danger on the vehicle operation road, for example, car accidents, pedestrians on the highway, or vehicles that are too close to each other. Traffic sign type can be used to describe the type of sign that indicates vehicle driving rules, for example, red traffic lights, circular signs, or rectangular signs.

[0097] Specifically, the target type corresponds to an object that may affect vehicle driving safety. Each target type can correspond to at least one object. At least one object to be displayed corresponding to the target type is filtered from the objects in the vehicle environment information and the vehicle pre-display information to obtain objects to be displayed corresponding to the environmental hazard type, vehicle operation hazard type, and traffic sign type.

[0098] In one example, objects in the vehicle environment information and the vehicle pre-display information are screened for puddles corresponding to environmental hazard types.

[0099] S307: Obtain the object space position and object size corresponding to each object to be displayed.

[0100] Specifically, based on the vehicle environment information and the vehicle pre-display information, the object space position and object size corresponding to each object to be displayed are obtained, redundant information is removed, and the efficiency of data processing is improved.

[0101] In one example, the object spatial position corresponding to each puddle to be displayed is obtained to be 100 meters in front of the vehicle and the object size is a circle with a diameter of 1 meter.

[0102] S308 : Calculate the actual distance between each object to be displayed and the vehicle based on the vehicle environment information, the vehicle pre-display information, and the object space position of each object to be displayed.

[0103] The actual distance may be used to describe the distance between the object to be displayed and the real-time driving position of the vehicle.

[0104] Specifically, based on vehicle environmental information and vehicle pre-display information, as well as the spatial position of each object to be displayed, the actual distance between each object to be displayed and the vehicle is calculated, and the distance between objects that may affect driving safety and the vehicle is obtained. Targeted processing can be performed in advance to improve driving safety.

[0105] In one example, based on the vehicle environment information, the vehicle pre-display information, and the object spatial position of the puddle, the actual distance between the puddle and the vehicle is calculated to be 100 meters.

[0106] S309 : Generate image information to be projected according to the actual distance between each object to be displayed and the vehicle and the object size of each object to be displayed.

[0107] Specifically, image information to be projected is generated based on the actual distance between each object to be displayed and the vehicle and the object size of each object to be displayed. The distance between each object to be displayed and the actual driving position of the vehicle and the object size of the object to be displayed can be seen through the image information to be projected, which makes it convenient for the driver to perform different operations for different objects to be displayed in advance, thereby improving the safety of vehicle driving.

[0108] In one example, the object to be displayed is a puddle, and the image information to be projected is generated based on the actual distance between the object to be displayed and the vehicle being 100 meters and the object size of each object to be displayed being a circle with a diameter of 1 meter.

[0109] S310: Projecting the image information to be projected through the holographic projection vehicle light.

[0110] In an embodiment of the present invention, at least one object to be displayed corresponding to a target type is screened from objects in the vehicle environment information and the vehicle pre-display information, the object spatial position and object size corresponding to each object to be displayed are obtained, and the actual distance between each object to be displayed and the vehicle is calculated based on the vehicle environment information and the vehicle pre-display information, as well as the object spatial position of each object to be displayed. Image information to be projected is generated based on the actual distance between each object to be displayed and the vehicle and the object size of each object to be displayed. The distance between objects around the vehicle that may affect driving safety and the real-time driving position of the vehicle and the object size of the objects can be projected, and the distance between objects that may affect driving safety at a certain distance from the vehicle and the target position of the vehicle and the object size of the objects can also be pre-projected, which is beneficial for the driver to obtain multi-dimensional environmental information and improve the safety of vehicle driving.

[0111] Optionally, the image information to be projected is generated based on the actual distance between each object to be displayed and the vehicle and the object size of each object to be displayed, including: obtaining a preset object projection ratio; calculating the actual display size corresponding to the object size of each object to be displayed based on the preset object projection ratio; and generating the image information to be projected based on the actual distance between each object to be displayed and the vehicle and the actual display size corresponding to each object to be displayed.

[0112] The preset object projection ratio may be used to describe the display ratio of the object to be displayed in the image information to be projected, and the actual display size may be used to describe the object size of the object to be displayed after the object size is reduced according to the preset object projection ratio.

[0113] Specifically, a preset object projection scale is obtained, including but not limited to user input or touchscreen selection, which is not limited in this embodiment of the present invention. Based on the preset object projection scale, the actual display size corresponding to the object size of each object to be displayed is calculated, where the actual display size is equal to the product of the object size and the preset object projection scale. Image information to be projected is generated based on the actual distance between each object to be displayed and the vehicle and the actual display size of each object to be displayed.

[0114] In one example, a preset object projection scale of 10% is obtained. Based on the preset object projection scale, the object size of the puddle to be displayed is calculated as a circle with a diameter of 0.5 meters, and the corresponding actual display size is a circle with a diameter of 0.05 meters. Image information to be projected is generated based on the actual distance between each object to be displayed and the vehicle and the actual display size of each object to be displayed.

[0115] By calculating the actual display size corresponding to the object size of each object to be displayed based on the preset object projection ratio, and generating the image information to be projected based on the actual distance between each object to be displayed and the vehicle and the actual display size corresponding to each object to be displayed, more information can be displayed in a limited display area, and driving operation judgments can be made through multi-dimensional data, thereby improving vehicle driving accuracy.

[0116] Optionally, projecting the image information to be projected by using a holographic projection lamp includes: projecting the image information to be projected by using the holographic projection lamp into the air of a target area parallel to the front windshield of the vehicle.

[0117] The target area can be used to describe the area to be projected.

[0118] Specifically, when the distance between vehicles is too close, if the data projected by the vehicle is projected directly in front, it may cause the information projected by the vehicle to be unclear. Projecting the image information to be projected through holographic projection lights into the air of the target area parallel to the front windshield of the vehicle is conducive to the accuracy of viewing the image information to be projected.

[0119] In one example, the image information to be projected includes a speed limit sign, which is 100 meters away from the real-time driving position of the vehicle. The image information to be projected is projected into the air of a target area parallel to the front windshield of the vehicle through a holographic projection headlight.

[0120] By projecting the image information to be projected into the air of a target area parallel to the vehicle's front windshield through holographic projection lights, no medium is required and the projection can be directly performed in the air. The projection is not affected by the environment, thereby improving the accuracy of vehicle information projection.
