Description

Technical Field

[0001] This application relates to the field of vehicle automatic control technology, and in particular to a vehicle passenger seat intelligent sun protection method, system, automobile, computer equipment, and storage medium. Background Technology

[0002] With technological advancements and social development, the number of cars on the road continues to increase, making automobiles a common mode of transportation. Furthermore, with the development of intelligent technologies, autonomous vehicles are gradually entering our lives, changing the way we live, work, and play, and creating a safer and more efficient road transportation environment. In both autonomous and non-autonomous vehicles, front-seat passengers are easily exposed to sunlight due to the influence of buildings and other factors. Therefore, current car manufacturers install sun visors and other sun-shading devices in vehicles to protect front-seat passengers from direct sunlight.

[0003] In existing technology, when a front passenger is exposed to sunlight, they need to manually adjust the vehicle's sun shade to achieve the desired sun protection. However, manually adjusting the sun shade has the following drawbacks: First, adjusting the sun shade while driving can distract the driver and compromise safe driving; second, manual adjustment may damage the sun shade due to improper operation by the front passenger. Vehicle manufacturers have gradually recognized these technical problems, and many vehicles on the market now use automatic sun shading systems for front passenger protection. However, current intelligent sun protection methods for front passengers have the following drawbacks: First, they can only control a single sun shade and cannot coordinate multiple sun shades; second, the sun protection effect is poor, specifically in terms of difficulty in accurately identifying the area to be shaded and accurately determining the adjustment angle of the sun shade, especially the angle of the sun visor itself.

[0004] Therefore, there is an urgent need to propose a vehicle passenger-side intelligent sun protection method, system, and automobile that can solve the above-mentioned technical problems. Summary of the Invention

[0005] Therefore, it is necessary to provide a vehicle passenger-side intelligent sun protection method, system, automobile, computer equipment, and storage medium to address the above-mentioned technical problems, thereby resolving the discomfort caused by excessive sunlight exposure to the front passenger of a vehicle when the light intensity is too high; and to resolve potential damage to the sun shading device or driving safety issues caused by the front passenger manually adjusting the sun shading device, thus ensuring the safety of vehicle driving and the comfort of the front passenger.

[0006] On the one hand, a method for intelligent sun protection for the passenger side of a vehicle is provided, the method comprising:

[0024] In one embodiment, the side sunshade control rule further includes: when the sunshade is adjusted to the maximum adjustable range, re-collecting whether there is a sunshade area at the side sunshade position; if so, adjusting the seat along the X-axis until the sunshade area is completely blocked; wherein, the X-axis is the vehicle's driving direction.

[0025] In one embodiment, the method further includes: determining the horizontal central axis of the face image based on the acquired face image; determining the position of the area to be shaded relative to the horizontal central axis based on the determined area to be shaded and the horizontal central axis of the face image; and adjusting the seat along the X-axis based on the position of the area to be shaded relative to the horizontal central axis until the area to be shaded is completely shaded.

[0026] In one embodiment, the seat is adjusted along the X-axis based on the position of the area to be shaded relative to the horizontal centerline until the area to be shaded is completely shaded. This includes: when the area to be shaded is above the horizontal centerline, adjusting the seat along the X-axis in the direction opposite to the vehicle's travel direction until the area to be shaded is completely shaded; and when the area to be shaded is below the horizontal centerline, adjusting the seat along the X-axis in the vehicle's travel direction until the area to be shaded is completely shaded.

[0027] In one embodiment, when the sun visor is adjusted to the target adjustment angle, the presence of a sun-shading area at the front sun-shading position is re-acquired.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0051] Example 1

[0052] The intelligent sun protection method for the passenger side of the vehicle provided in this application, such as Figure 1 As shown, the method includes:

[0053] Collect facial images of the front passenger in the vehicle;

[0054] Based on the face image, obtain the light sensitivity value of the face image to determine the area of ​​the face image to be shaded;

[0055] Adjust the vehicle's sunshade and seats based on the area to be shaded until the area is covered.

[0056] In one embodiment, acquiring a facial image of a vehicle's front passenger includes: in response to a vehicle front passenger smart sun protection trigger signal, identifying facial feature points according to an OMS recognition algorithm; wherein the vehicle front passenger smart sun protection trigger signal includes a vehicle front passenger smart sun protection activation request, and / or, the current light intensity is greater than a preset light intensity; determining the facial image of the vehicle front passenger based on the facial feature points; wherein the facial feature points include at least one of a nose, eyes, mouth, and ears. It should be understood that this application does not limit the specific value of the preset light intensity, and those skilled in the art can limit it according to the actual situation.

[0057] In one embodiment, determining the area to be shaded based on the light sensitivity value of the face image includes: acquiring coordinate points corresponding to light sensitivity values ​​greater than a preset light sensitivity value based on the acquired light sensitivity value of the face image; determining edge coordinate points from the coordinate points, wherein the edge coordinate points are the coordinate points with the longest straight-line distance from the preset coordinate origin; and drawing a circle with the straight-line distance between the edge coordinate points and the preset coordinate origin as the radius and the preset coordinate origin as the center, and determining the face image area covered by the circle as the area to be shaded.

[0058] It should be understood that when determining the area of ​​the face image covered by the circle as the area to be shaded, there is a possibility that areas not exposed to sunlight (i.e., light sensitivity values ​​not greater than a preset light sensitivity value) may also be included in the area to be shaded. Therefore, in one embodiment, the method further includes: when adjusting the sunshade device and seat of the vehicle to shade the area to be shaded, detecting in real time whether there is an area to be shaded in the face image (i.e., detecting in real time whether there are coordinate points on the face image with light sensitivity values ​​greater than a preset light sensitivity value); when it is detected that there is no area to be shaded in the face image, the adjustment of the sunshade device and seat of the vehicle is stopped.

[0059] In one embodiment, the method further includes: when determining the area to be shaded in the face image, the method further includes: determining whether the light sensitivity value at the location of the facial feature point is greater than a preset light sensitivity value; when the light sensitivity value at the location of the facial feature point is greater than the preset light sensitivity value, then the facial feature point is determined to be the area to be shaded. For example, when the light sensitivity value at the eye location is detected to be greater than the preset light sensitivity value, then the eye is determined to be the area to be shaded; that is, in practical application scenarios, only key parts such as the eyes can be shaded, without having to shade areas of the entire face where the light sensitivity value is greater than the preset light sensitivity value.

[0060] In one embodiment, the method further includes: determining the angle between the vertical plane of the area to be shaded and the vertical plane of the vehicle window based on the area to be shaded; and determining the position to be shaded based on the angle, wherein the position to be shaded includes a frontal position and a side position. Specifically, in practical applications, the vertical plane of the vehicle window is the outer tangent plane of the vehicle window perpendicular to the ground.

[0061] To avoid the inability to obtain the angle between the vertical plane of the area to be shaded and the vertical plane of the vehicle window when the vehicle window is open, those skilled in the art can add an image acquisition unit to the vehicle to collect facial images of the passenger from various angles.

[0062] In one embodiment, the vehicle's sunshade device includes a sunshade curtain and a sunshade panel; adjusting the vehicle's sunshade device and seats based on the area to be shaded until the area to be shaded is blocked includes: when the area to be shaded includes a side area to be shaded, adjusting the sunshade curtain and seats according to side shading control rules until the area to be shaded at the side area to be shaded is blocked; when the area to be shaded includes a front area to be shaded, adjusting the sunshade panel and seats according to front shading control rules until the area to be shaded at the front area to be shaded is blocked.

[0063] In one embodiment, the front sunshade control rule includes: obtaining the highest and lowest coordinate points of the sunshade area at the front sunshade location, wherein the highest coordinate point is the coordinate point furthest from the vehicle's seat along the Z-axis direction, and the lowest coordinate point is the coordinate point closest to the vehicle's seat along the Z-axis direction; determining the area length of the sunshade area based on the highest and lowest coordinate points; projecting the hinge axis of the sun visor onto the plane where the sunshade area is located to obtain the actual vertical distance between the projection of the highest coordinate point and the hinge axis of the sun visor, and obtaining the width of the sun visor; inputting the area length, the actual vertical distance, and the width of the vehicle's sun visor into a preset trained sun visor angle adjustment model to determine the target adjustment angle of the sun visor; rotating the sun visor along its hinge axis based on the target adjustment angle, and monitoring in real time whether the sunshade area is completely blocked, stopping the rotation of the sun visor when the sunshade area is completely blocked. Wherein, the Z-axis is a vertical direction perpendicular to the vehicle's direction of travel, such as... Figure 4 As shown.

[0064] In one embodiment, the pre-trained sunshade angle adjustment model includes:

[0065]

[0066] Where θ is the target adjustment angle of the sun visor determined based on the preset trained sun visor angle adjustment model; A is the region length; C is the width of the sun visor; and B is the actual vertical distance between the plane where the highest coordinate point is located and the plane where the hinge axis of the sun visor is located, determined based on the highest coordinate point.

[0067] In one embodiment, such as Figure 2 As shown, the front sunshade rule further includes: when the sun visor is adjusted to the target adjustment angle, re-collecting whether there is a sunshade area at the front sunshade position; if so, adjusting the seat along the Z-axis; wherein, the Z-axis is a vertical direction perpendicular to the vehicle's driving direction. That is, adjusting the seat along the Z-axis means adjusting the seat upwards or downwards based on the sunshade area.

[0068] In one embodiment, such as Figure 2 As shown, the front shading control rules further include: obtaining the leftmost and rightmost coordinate points of the shading area at the front shading position, and the leftmost and rightmost edge points of the sunshade; adjusting the sunshade along the Y-axis based on the first vertical distance between the vertical plane where the leftmost coordinate point is located and the vertical plane where the leftmost edge point is located, and the second vertical distance between the vertical plane where the rightmost coordinate point is located and the vertical plane where the rightmost edge point is located; wherein, the Y-axis is a horizontal direction parallel to the ground, such as... Figure 4 As shown. Adjusting the sunshade along the Y-axis direction, i.e., adjusting it to the left or right, is defined as adjusting towards the driver's side as left and adjusting towards the passenger's side as negative in practical applications.

[0069] In one embodiment, before adjusting the sunshade along the Y-axis based on a first vertical distance between the vertical plane of the leftmost coordinate point and the vertical plane of the leftmost edge point, and a second vertical distance between the vertical plane of the rightmost coordinate point and the vertical plane of the rightmost edge point, the method further includes: if the first vertical distance and / or the second vertical distance is 0, then the sunshade is not adjusted; if the first vertical distance and / or the second vertical distance is not 0, then the sunshade is adjusted along the Y-axis based on the positive or negative values ​​of the first vertical distance and the second vertical distance; wherein, when the leftmost coordinate point is located to the right of the leftmost edge point, the first vertical distance is defined as positive, and vice versa; when the rightmost coordinate point is located to the left of the rightmost edge point, the second vertical distance is defined as positive, and vice versa.

[0070] In one embodiment, adjusting the light-shielding plate along the Y-axis based on the sign of the first vertical distance and the second vertical distance includes: if the first vertical distance is positive and the second vertical distance is negative, adjusting the light-shielding plate to the right along the Y-axis until either the first vertical distance or the second vertical distance is 0; if the first vertical distance is negative and the second vertical distance is positive, adjusting the light-shielding plate to the left along the Y-axis until either the first vertical distance or the second vertical distance is 0.

[0071] In one embodiment, adjusting the sunshade along the Y-axis based on the sign of the first vertical distance and the second vertical distance includes: if the signs of the first vertical distance and the second vertical distance are the same, then not adjusting the sunshade; or, adjusting the sunshade along the Y-axis until the first vertical distance or the second vertical distance is 0.

[0072] In one embodiment, such as Figure 3 As shown, the side sunshade control rules include: adjusting the vehicle's sunshade curtain along the X-axis and monitoring in real time whether the area to be shaded is completely blocked. Once the area to be shaded is completely blocked, the adjustment of the vehicle's sunshade curtain is stopped. Stopping the adjustment of the vehicle's sunshade curtain after the area to be shaded is completely blocked ensures that the area to be shaded is blocked, improving the comfort of the front passenger; on the other hand, it ensures that the front passenger can see the scenery outside the vehicle.

[0073] In one embodiment, the side sunshade control rule further includes: when the sunshade is adjusted to its maximum adjustable range, re-collecting whether there is a sunshade area at the side sunshade position; if so, adjusting the seat along the X-axis until the sunshade area is completely blocked; wherein, the X-axis is the vehicle's driving direction, such as... Figure 4 As shown.

[0074] In one embodiment, when the sunshade is adjusted to its maximum adjustable range, the presence of a sunshade area at the side sunshade position is re-acquired. If a sunshade area exists, the seat is adjusted along the X-axis until the sunshade area is completely covered. This includes: determining the horizontal centerline of the face image based on the acquired face image; determining the position of the sunshade area relative to the horizontal centerline based on the determined sunshade area and the horizontal centerline of the face image; and adjusting the seat along the X-axis based on the position of the sunshade area relative to the horizontal centerline until the sunshade area is completely covered.

[0075] In one embodiment, the seat is adjusted along the X-axis based on the position of the area to be shaded relative to the horizontal centerline until the area to be shaded is completely shaded. This includes: when the area to be shaded is above the horizontal centerline, adjusting the seat along the X-axis in the direction opposite to the vehicle's travel direction until the area to be shaded is completely shaded; and when the area to be shaded is below the horizontal centerline, adjusting the seat along the X-axis in the vehicle's travel direction until the area to be shaded is completely shaded.

[0076] In one embodiment, when the sun visor is adjusted to the target adjustment angle, the presence of a sun-shading area at the front sun-shading position is re-acquired. If a sun-shading area exists, the seat is adjusted along the Z-axis and / or along the X-axis. This includes: determining whether the sun-shading area at the re-acquired front sun-shading position is located below the sun-shading area obscured by the sun visor; if so, acquiring the projection length of the sun-shading area at the front sun-shading position on the Z-axis; adjusting the seat upwards along the Z-axis based on the projection length; wherein the seat adjustment height is not less than the projection length; and / or adjusting the seat along the X-axis in a direction opposite to the vehicle's driving direction until the sun-shading area no longer exists. It is important to understand that in real-world applications, the following situation is highly likely: the area to be shaded at the re-collected frontal sunshade position may be located to the left, right, or below the sunshade area already covered by the sun visor (in reality, the re-collected frontal sunshade area will not be above the sunshade area already covered by the sun visor, because the top of the sun visor is the roof, and the roof also effectively shades the sunshade area). Adjusting the seat along the Z-axis can only shade the lower sunshade area, so it is necessary to determine the specific location of the re-collected sunshade area.

[0077] In one embodiment, adjusting the vehicle's sunshade device based on the area to be shaded and the position to be shaded until the area to be shaded is blocked includes: when the position to be shaded includes a side position and a front position, adjusting the sunshade curtain and seat based on the side shading control rules until the area to be shaded at the side position is shaded; after the area to be shaded at the side position is shaded, re-collecting the light sensitivity value of the current face image to determine the area to be shaded at the front position of the face image, and adjusting the sunshade panel and seat based on the front shading control rules until the area to be shaded at the front position is shaded. The side position is shaded first because the adjustment paths of the sunshade curtain and the seat are fixed. Furthermore, in practical applications, when adjusting the sunshade curtains and seats to block the sunshade area on the side, it is possible to partially or even completely block the sunshade area on the front at the same time. This can reduce or even eliminate the need to adjust the sunshade and seats, thereby reducing workload to some extent.

[0078] The aforementioned intelligent sun protection method for the front passenger seat of a vehicle automatically and adaptively adjusts the sunshades and seats of multiple vehicles through coordinated control, ultimately achieving the beneficial effect of shielding the area to be shielded from the sun. On the one hand, it solves the problem of potential damage to the sunshades caused by manual adjustment by the front passenger in real-world situations; on the other hand, it reduces interference with the driver's safe driving caused by the front passenger adjusting the sunshades, ensuring driving safety; furthermore, by using the sunshades to shield the area to be shielded, it improves the comfort of the front passenger and provides effective sun protection.

[0079] It should be understood that, although Figures 1-3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figures 1-3 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
