[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Please refer to Figure 1 , Figure 1This is a flow chart of a display control method of a vehicle-mounted AR provided by an embodiment of the present invention. The method may include:

[0042] Step 101: Acquire environmental information of the vehicle; wherein the environmental information includes road condition information and / or weather information.

[0043] It can be understood that the environmental information of the vehicle in this embodiment can be information about the environment in which the vehicle is located, such as environmental information at the location of the vehicle. The specific content of the environmental information of the vehicle in this step can be set by the designer according to the practical scenario and user needs. For example, the environmental information can include road condition information; for example, the road condition information can include at least two of tunnel road conditions, normal road conditions and under-bridge road conditions; for example, when the road condition information includes tunnel road conditions, normal road conditions and under-bridge road conditions, when the current location of the vehicle is in the tunnel, the road condition information can be tunnel road conditions; when the current location of the vehicle is on a normal road, the road condition information can be normal road conditions; when the current location of the vehicle is under a bridge, the road condition information can be under-bridge road conditions. The environmental information can also include weather information; for example, the weather information can include at least two of daytime sunny weather, daytime cloudy weather, daytime rainy weather and nighttime weather. This embodiment does not impose any restrictions on this.

[0044] It should be noted that the display control method of the vehicle-mounted AR provided in this embodiment can be applied to the augmented reality head-up display (AR-HUD) on the vehicle, that is, the processor of the AR-HUD can dynamically adjust the refractive index (i.e., light transmittance) on the AR-HUD by using the acquired environmental information and illumination data; the display control method of the vehicle-mounted AR provided in the embodiment can be applied to devices that are connected to the AR-HUD on the vehicle, such as the central control device on the vehicle or the server in the cloud; for example, the processor of the central control device on the vehicle can use the acquired environmental information and illumination data to communicate and control the refractive index on the AR-HUD to dynamically adjust. This embodiment does not impose any restrictions on this.

[0045] Correspondingly, the specific way in which the processor obtains the vehicle's environmental information in this step can be set by the designer according to practical scenarios and user needs. For example, the processor can query the vehicle's environmental information based on the vehicle's location information; for example, when the method provided in this embodiment is applied to the central control device on the vehicle, the processor of the central control device can query the vehicle's environmental information from the network and / or pre-downloaded navigation data based on the vehicle's location information. The processor can also directly receive the vehicle's environmental information; for example, when the method provided in this embodiment is applied to the AR-HUD on the vehicle, the AR-HUD's processor can receive the environmental information corresponding to the vehicle's location sent by the vehicle's central control device; Figure 2As shown, the AR-HUD processor can receive the environmental information corresponding to the position of the vehicle sent by the central control device (central console) through the CAN (Controller Area Network) bus; for example, when the processor obtains the environmental information of the vehicle at a first preset time interval, the central control device can query the environmental information of the vehicle according to the vehicle's position information at the first preset time interval, and send the queried vehicle environmental information to the AR-HUD, so that the AR-HUD processor can receive the environmental information corresponding to the position of the vehicle sent by the central control device at the first preset time interval. This embodiment does not impose any limitation on this.

[0046] Step 102: Obtain light data collected by a light sensor on the vehicle.

[0047] The light sensor in this embodiment may be an optical sensor provided on the vehicle for collecting light intensity data (ie, light data) of external ambient light.

[0048] Correspondingly, the specific number and location of the light sensors on the vehicle in this embodiment can be set by the designer according to practical scenarios and user needs. For example, the light sensors can be set inside the vehicle to collect light intensity data of ambient light passing through the windows inside the vehicle. This embodiment does not impose any restrictions on this.

[0049] It is understandable that this embodiment does not limit the specific order of step 101 and step 102. Step 101 may be performed first and then step 102 as shown in this embodiment; step 102 may be performed first and then step 101, or both steps may be performed simultaneously.

[0050] Correspondingly, in this step, the processor may acquire the illumination data collected by the light sensor on the vehicle at a second preset time interval. The second preset time may be the same as or different from the first preset time, and this embodiment does not impose any limitation on this.

[0051] Step 103: Control and adjust the refractive index of the augmented reality head-up display on the vehicle according to the environmental information and the illumination data.

[0052] It is understandable that in this step, the processor can combine the vehicle's environmental information and lighting data to dynamically adjust the light transmittance on the AR-HUD, improve the light intensity environment inside the vehicle, reflect the technological sense of the AR-HUD, and enhance the user experience.

[0053] Correspondingly, the specific way in which the processor controls and adjusts the refractive index of the augmented reality head-up display on the vehicle according to the environmental information and illumination data in this step can be set by the designer according to the practical scenario and user needs. For example, in this step, the processor can determine the refractive index corresponding to the illumination data (i.e., the illumination refractive index) according to the preset correspondence between illumination and refractive index; determine the final refractive index corresponding to the illumination refractive index according to the environmental information; and adjust the refractive index of the augmented reality head-up display to the final refractive index. In other words, the processor can first use the illumination data to determine the illumination refractive index corresponding to the illumination data; then use the environmental information of the vehicle to adjust the illumination refractive index to obtain the final refractive index, so as to adjust the refractive index of the AR-HUD to the final refractive index.

[0054] Accordingly, in this step, the processor may also determine the target gear mode of the augmented reality head-up display according to the environmental information; determine the target refractive index corresponding to the illumination data in the target gear mode; and adjust the refractive index of the augmented reality head-up display to the target refractive index; wherein the target gear mode is any preset gear mode. In other words, each preset gear mode may include a corresponding relationship between illumination and refractive index; the processor may first determine a corresponding preset gear mode (i.e., the target gear mode) using the environmental information of the vehicle; and then determine the refractive index corresponding to the illumination data (i.e., the target refractive index) according to the corresponding relationship between illumination and refractive index in the target gear mode, so as to adjust the refractive index of the AR-HUD to the target refractive index.

[0055] Furthermore, in this embodiment, after the processor controls the adjustment of the refractive index of the augmented reality head-up display on the vehicle according to the environmental information and lighting data, it can control the augmented reality head-up display to display the vehicle's prompt information (such as road condition change information) according to the adjusted refractive index.

[0056] Correspondingly, the specific content of the above prompt information can be set by the designer according to practical scenarios and user needs. For example, the prompt information can include conventional prompt information such as vehicle speed, rotation speed, navigation and fault warning information; the prompt information can also include road condition change information to prompt the user of road condition changes; Figure 3 As shown, when the road condition changes from tunnel condition to normal road condition, the processor can display the following Figure 3 The road condition change image (i.e., road condition change information) shown is used to remind the driver that the vehicle is about to leave the tunnel.

[0057] In this embodiment, the embodiment of the present invention controls and adjusts the refractive index of the augmented reality head-up display on the vehicle according to the environmental information and lighting data, and can use the lighting data to integrate the environmental information of the vehicle, dynamically adjust the light transmittance on the AR-HUD, improve the light intensity environment inside the vehicle, reflect the technological sense of the AR-HUD, and enhance the user experience.

[0058] Based on the above embodiment, the present invention also provides another display control method of vehicle-mounted AR. Figure 4 , Figure 4 This is a flow chart of another display control method of vehicle-mounted AR provided by an embodiment of the present invention. The method may include:

[0059] Step 201: AR-HUD obtains environmental information corresponding to the location of the vehicle sent by the central control device of the vehicle; wherein the environmental information includes road condition information and / or weather information.

[0060] It is understandable that in this step, the processor of the AR-HUD in the vehicle can receive the environmental information corresponding to the position of the vehicle sent by the central control device. Accordingly, the central control device can query and send the environmental information of the position to the AR-HUD according to the current position of the vehicle.

[0061] Step 202: Acquire light data collected by a light sensor on the vehicle.

[0062] This step is similar to step 102 and will not be described again here.

[0063] Step 203: Determine a target gear mode of the AR-HUD according to the environmental information; wherein the target gear mode is any preset gear mode.

[0064] It is understandable that in this step, the processor can determine any preset gear mode (ie, target gear mode) that the AR-HUD is to enter according to the environmental information of the vehicle. Each preset gear mode may include a corresponding relationship between the illumination and the refractive index.

[0065] Correspondingly, the specific number and type of settings for the preset gear mode in this step can be set by the designer according to practical scenarios and user needs. For example, the preset gear mode can be set using weather information; for example, when the weather information is divided into sunny weather during the day, cloudy weather during the day, and night weather, the preset gear mode may include night mode, cloudy mode, and sunny mode; when the weather information is divided into sunny weather during the day, cloudy weather during the day, rainy weather during the day, and night weather, the preset gear mode may include night mode, cloudy mode, rainy mode, and sunny mode. The preset gear mode can also be set using road condition information or road condition information and weather information. For example, the preset gear mode can also include a tunnel mode corresponding to tunnel road conditions. This embodiment does not impose any restrictions on this.

[0066] It should be noted that the specific method for the processor to determine the target gear mode of the AR-HUD according to the environmental information in this step can be set by the designer. For example, the processor can match the current target gear mode of the AR-HUD according to the current environmental information obtained. For example, when the environmental information includes road condition information and weather information, the road condition information includes tunnel road conditions and normal road conditions, and the weather information is divided into daytime sunny weather, daytime cloudy weather and nighttime weather, the processor can determine the night mode as the target gear mode when the road condition information is tunnel road conditions; when the road condition information is normal road conditions, when the weather information is daytime sunny weather, the sunny mode is determined as the target gear mode; when the weather information is daytime cloudy weather, the cloudy mode is determined as the target gear mode; when the weather information is nighttime weather, the night mode is determined as the target gear mode; wherein the preset gear modes include night mode, cloudy mode and sunny mode. That is, when the environmental information includes road condition information and weather information, the matching priority of the road condition information may be higher than that of the weather information because different road conditions have a greater impact on the ambient light outside the vehicle.

[0067] Furthermore, before this step, the processor can also determine whether the current weather information is the same as the weather information obtained last time; if not, enter step 203 to determine the current new target gear mode of the AR-HUD based on the current weather information; if so, the preset gear mode of the AR-HUD is determined as the current target gear mode of the AR-HUD to keep the target gear mode of the AR-HUD unchanged.

[0068] Step 204: Determine the target refractive index corresponding to the illumination data in the target gear mode.

[0069] It can be understood that the target refractive index in this step may be the refractive index of the AR-HUD corresponding to the illumination data in the target gear mode.

[0070] Correspondingly, the specific method for the processor to determine the target refractive index corresponding to the illumination data under the target gear mode in this step can be set by the designer according to practical scenarios and user needs. For example, when a corresponding relationship between illumination and refractive index corresponding to each preset gear mode is pre-stored, the processor can directly use the corresponding relationship between illumination and refractive index corresponding to the target gear mode to calculate the refractive index corresponding to the illumination data (i.e., the target refractive index). In the present embodiment, a plurality of correspondences between illumination and refractive index corresponding to each preset gear mode may be pre-stored; for example, when the correspondences between illumination segments and refractive indexes within a preset illumination range corresponding to each preset gear mode are pre-stored, the processor in this step may determine the target refractive index corresponding to the illumination data based on the correspondence between the target illumination segment and the refractive index in the target gear mode; wherein each preset gear mode includes the correspondences between the illumination segments and the refractive indexes within the preset illumination range corresponding to each preset gear mode, and the target illumination segment is the illumination segment corresponding to the illumination data in the target gear mode; that is, the processor may first determine an illumination segment (i.e., the target illumination segment) in the target gear mode corresponding to the illumination data; and then determine the refractive index (i.e., the target refractive index) corresponding to the illumination data based on the correspondence between the target illumination segment and the refractive index.

[0071] It should be noted that each preset gear mode can set a corresponding preset illumination range; by segmenting each preset illumination range, multiple illumination segments corresponding to each preset illumination range can be set; each illumination segment can set the correspondence between the illumination value and the refractive index within the segment, such as each illumination segment can correspond to a refractive index, that is, each illumination value within the illumination segment can correspond to a refractive index; each illumination segment can also set a corresponding relationship between the illumination value and the refractive index, that is, each illumination value within the illumination segment can be calculated through the corresponding relationship to obtain the corresponding refractive index.

[0072] For example, when the preset illumination range is segmented by arithmetic progression, the preset illumination range corresponding to the target gear mode includes the first illumination segment to the nth illumination segment, and the first illumination segment is a min To a1, the i-th lighting segment is a i to a i+1 , the nth lighting segment is a n to a max ; Among them, a min and a max are the minimum illumination value and the maximum illumination value in the preset illumination range corresponding to the target gear mode, respectively; i is a positive integer greater than or equal to 1 and less than or equal to n-1; a1-a min 、a i+1 -a i and a max -a n The values ​​are equal.

[0073] For example, when the preset gear mode includes a sunny mode and a cloudy mode, the preset illumination range corresponding to the sunny mode may be a preset minimum value b of the illumination intensity on a sunny day. min To b max ; Divide it into segments according to arithmetic progression to obtain illumination segments 1 to m; each illumination segment is set to correspond to a refractive index, that is, set the refractive index l corresponding to each of the m illumination segments b1 To bm ; When the target gear mode is sunny mode, if the illumination data is within any illumination segment, the refractive index corresponding to the illumination segment can be the target refractive index; if the illumination data is greater than b max , then the target illumination segment corresponding to the illumination data can be illumination segment m, and the refractive index corresponding to illumination segment m is l bm Can be the target refractive index; if the illumination data is less than b min , then the target illumination segment corresponding to the illumination data can be illumination segment 1, and the refractive index corresponding to illumination segment 1 is l b1 Can be the target refractive index.

[0074] The preset illumination range corresponding to the cloudy mode can be the preset minimum value c of the illumination intensity on a cloudy day. min to c max ; Divide it into segments according to arithmetic progression to obtain illumination segments 1 to q; each illumination segment is set to correspond to a refractive index, that is, set the refractive index l corresponding to each of the q illumination segments c1 To cq ; Among them, this embodiment does not limit the specific number and segment size of the illumination segments corresponding to each preset gear mode, that is, the number (m) of illumination segments corresponding to the above-mentioned sunny mode and the number (q) of illumination segments corresponding to the cloudy mode can be the same or different; the size of each illumination segment corresponding to the sunny mode (that is, the difference between the maximum value and the minimum value in the segment) can be the same as or different from the size of the illumination segment corresponding to the cloudy mode.

[0075] Step 205: Adjust the refractive index of the AR-HUD to the target refractive index.

[0076] It can be understood that in this step, the AR-HUD adjusts the refractive index of its own variable display screen to the target refractive index, so that the refractive index of the AR-HUD can be adjusted to the target refractive index corresponding to the lighting data in the vehicle's environment. That is, when the vehicle is in different environments, the target refractive index corresponding to the same lighting data may be different, so that the adjustment of the light transmittance on the AR-HUD can better meet user needs, further improve the light intensity environment in the car, reflect the technological sense of the AR-HUD, and enhance the user experience.

[0077] In this embodiment, the embodiment of the present invention determines the target gear mode of the AR-HUD according to environmental information, and can set preset gear modes when the vehicle is in different environments. By determining the target refractive index corresponding to the illumination data in the target gear mode, the target refractive index corresponding to the illumination data can be determined according to the correspondence between illumination and refractive index in the preset gear mode of the vehicle's environment. This allows the AR-HUD to dynamically adjust the light transmittance when the vehicle is in different environments, thereby improving the light intensity environment inside the vehicle and further enhancing the user experience.

[0078] Corresponding to the above method embodiment, an embodiment of the present invention further provides a display control device for a vehicle-mounted AR.
