[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The width trajectory display method provided in the embodiment of the present application can be applied in the application environment shown in Figure 1. When the computer device detects that the vehicle enters the preset scene, the steering wheel angle of the vehicle, the width trajectory, and the first distance between the vehicle and the obstacle are obtained; the width trajectory is constructed based on the vehicle width of the vehicle; the preset scene includes a narrow road scene and a meeting scene; according to the steering wheel angle and the first distance, the target color of the width trajectory is adjusted; through the augmented reality head-up display, the adjusted width trajectory is displayed on the front window of the vehicle. Among them, the computer device can be either a terminal or a server. The terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0052] In an exemplary embodiment, as shown in FIG2 , a method for displaying a width trajectory line is provided, and the method is applied to the computer device in FIG1 as an example for description, and includes the following steps 201 to 203. Among them:

[0053] Step 201, when it is detected that a vehicle enters a preset scene, the steering wheel angle of the vehicle, the width trajectory line, and the first distance between the vehicle and the obstacle are obtained.

[0054] The width track line is constructed based on the vehicle width, which can represent the width from the left side mirror to the right side mirror of the vehicle. The preset scenes include narrow road scenes and oncoming scenes. Obstacles can be oncoming vehicles or landmarks on both sides of the narrow road (such as road edge lines or walls, etc.).

[0055] Specifically, when the computer device detects that the vehicle enters a preset scenario, the steering wheel angle and width trajectory of the vehicle are obtained. At the same time, the first distance between the two sides of the vehicle and the obstacle is detected through the radar installed in the vehicle (such as a lidar and a millimeter-wave radar, etc.).

[0056] It should be noted that the width trajectory line can be a trajectory line predicted for the vehicle's forward movement based on the vehicle width and the steering wheel angle. The pair of width trajectory lines is the area swept by the vehicle, and the width trajectory lines will change with the change of the steering wheel angle.

[0057] Step 202, adjusting the target color of the width trajectory line according to the steering wheel angle and the first distance.

[0058] The target color may include a first preset color and a second preset color. The first preset color is used to indicate that the vehicle owner can safely pass through the preset scene according to the current driving state, that is, no scratches or collisions will occur. The second preset color is used to indicate that the vehicle owner may experience scratches or collisions according to the current driving state.

[0059] Specifically, the vehicle's forward direction and forward distance at the next moment are predicted based on the steering wheel angle, and the direction of the width trajectory line is adjusted based on the forward direction and forward distance. At the same time, based on the adjusted width trajectory line and the first distance, it is determined whether the vehicle will collide with an obstacle at the next moment. If a collision will occur, the target color of the width trajectory line is adjusted to the second preset color; if no collision will occur, the target color of the width trajectory line is adjusted to the first preset color.

[0060] It should be noted that, in this embodiment, a width-indicating track line may be generated according to the vehicle width and the steering wheel angle through a central speed controller (CSC), and a target color of the width-indicating track line may be adjusted according to the steering wheel angle and the first distance.

[0061] Step 203: Display the adjusted width trajectory line on the front window of the vehicle through an augmented reality head-up display.

[0062] Among them, the Augmented Reality-Head Up Display (AR-HUD) can be a device that projects driving information onto the windshield in front of the car owner, allowing the car owner to see the driving information at eye level.

[0063] In some embodiments, displaying the adjusted width track line on the front window of the vehicle includes: if the width track line is a first preset color, displaying the width track line of the first preset color on the front window of the vehicle, and outputting a voice reminder of safe passage; if the width track line is a second preset color, displaying the width track line of the second preset color on the front window of the vehicle, and outputting a voice reminder of the risk of collision. The first preset color may be green, and the second preset color may be red.

[0064] For example, as shown in the schematic diagram of the width trajectory line in FIG3 , the enhanced display head-up display is located in front of the steering wheel, and the width trajectory line can be projected on the front window to assist the owner in determining the distance between the vehicle and the wall, so that the owner can smoothly pass the preset scene (i.e., a narrow road scene with walls on both sides).

[0065] It should be noted that this embodiment can also adjust the target color of the width trajectory line to red and flash, and output an alarm sound reminder when encountering emergencies during actual driving, such as other vehicles or pedestrians suddenly appearing in front of the vehicle and conflicting with the current width trajectory line.

[0066] The above width trajectory display method obtains the vehicle's steering wheel angle, width trajectory, and the first distance between the vehicle and the obstacle when the vehicle is detected to have entered a preset scene; the width trajectory is constructed based on the vehicle width of the vehicle; the preset scenes include narrow road scenes and meeting scenes; the target color of the width trajectory is adjusted according to the steering wheel angle and the first distance; the adjusted width trajectory is displayed on the front window of the vehicle through an augmented reality head-up display. In the preset scene, the present application assists the owner in reducing the probability of vehicle scratches and helps the owner pass the preset scene smoothly through the width trajectory in the preset scene.

[0067] In some embodiments, the color of the width trajectory line is adjusted according to the steering wheel angle and the first distance, including: determining the second distance between the vehicle and the obstacle according to the steering wheel angle and the first distance; if the second distance is greater than a preset collision threshold, adjusting the width trajectory line to the first preset color; if the second distance is not greater than the preset collision threshold, adjusting the width trajectory line to the second preset color.

[0068] In some embodiments, determining a second distance between the vehicle and an obstacle based on the steering wheel angle and the first distance includes: predicting the vehicle's driving distance based on the steering wheel angle and the vehicle speed; and using the difference between the first distance and the driving distance as the second distance between the vehicle and the obstacle.

[0069] Specifically, the steering wheel angle and the vehicle speed at the current moment are obtained, and the driving direction and driving distance of the vehicle at the next moment are predicted based on the steering wheel angle and the vehicle speed, and the difference between the first distance and the driving distance is used as the second distance between the vehicle and the obstacle.

[0070] Exemplarily, when the second distance is greater than the preset collision threshold, the vehicle will not collide with the obstacle at the next moment and can continue to drive safely, so the width trajectory line is adjusted to the first preset color; when the second distance is not greater than the preset collision threshold, the vehicle will collide with the obstacle at the next moment, and there is a risk of scratching or collision, so the width trajectory line is adjusted to the second preset color.

[0071] This embodiment can more accurately determine the adjustment color of the wide track line to more accurately assist the vehicle owner in driving through the preset scene.

[0072] In some embodiments, a method for detecting whether a vehicle enters a preset scene includes: obtaining a third distance between the vehicle and an obstacle collected by a radar device in the vehicle; and determining that the vehicle has entered the preset scene when the third distance is less than a preset distance threshold.

[0073] Specifically, a third distance between both sides of the vehicle and the obstacle collected by a radar device in the vehicle is obtained. When the distance between both sides of the vehicle and the obstacle is less than a preset distance threshold, it is determined that the vehicle has entered a preset scene.

[0074] For example, if the third left distance between the left side of the vehicle and the left obstacle is less than the preset distance threshold, and at the same time, the third right distance between the right side of the vehicle and the right obstacle is less than the preset distance threshold, then it proves that there are obstacles on both sides of the vehicle and the distances to the obstacles are close, and it is determined that the vehicle has entered the preset scene.

[0075] In some embodiments, determining that a vehicle has entered a preset scene includes: acquiring an environmental image of the vehicle's surroundings captured by a camera device; if it is detected that the environmental image contains street features, determining that the vehicle has entered a narrow road scene; if it is detected that the environmental image contains street features and other vehicle features, determining that the vehicle has entered a meeting scene.

[0076] Specifically, the environmental image around the vehicle is captured by a camera device, and image analysis is performed on the environmental image to determine the type of image features contained in the environmental image. If it is detected that the environmental image contains street features, it is determined that the vehicle has entered a narrow road scene; if it is detected that the environmental image contains street features and other vehicle features, it is determined that the vehicle has entered a meeting scene.

[0077] It should be noted that after the vehicle is determined to enter the preset scene, the AR-HUD auxiliary width display function will be automatically activated, and the width trajectory line will be displayed through the augmented reality head-up display. That is to say, when the vehicle is detected entering a narrow road scene (such as a narrow street) or a meeting scene (such as a narrow road meeting), the AR-HUD auxiliary width display function will be automatically activated. At the same time, the owner can also manually activate the AR-HUD auxiliary width display function.

[0078] This embodiment can accurately detect whether the vehicle enters a preset scene, and turn on the augmented reality head-up display only when the owner needs it, thereby reducing the vehicle's power consumption.

[0079] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
