[0002] Currently, the blind area display of vehicles on the market mainly relies on the combined configuration of surround-view cameras and panoramic cameras.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0021] It should be understood that in the claims, the description and the drawings of the present disclosure, terms such as "first", "second", and "third" are used to distinguish different objects, rather than to describe a specific order. The terms "comprising" and "including" used in the description and claims of the present disclosure indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations. It should also be understood that the terms used in the description of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0022] Referring to Figure 1 , an embodiment of the present invention discloses a blind area display method, including the following steps.

[0023] S1. Obtain image data around the vehicle.

[0024] Specifically, the original image data of the vehicle's surrounding environment is collected in real time through in-vehicle cameras (such as surround-view cameras and panoramic cameras).

[0025] In some embodiments, for a vehicle equipped only with surround-view cameras, the fisheye images in all directions of left, right, front, and rear can be obtained by using the surround-view video stream.

[0026] In some embodiments, for a vehicle equipped with panoramic cameras, the omnidirectional image data around the vehicle can be obtained through the multi-angle cameras of the panoramic system.

[0027] In some embodiments, according to the vehicle configuration and driving scenario requirements, relevant cameras (such as left or right cameras) can also be called in real time to obtain the image data in a specific direction.

[0028] S2. Determine the blind area to be displayed according to the driving state of the vehicle and the preset user preferences.

[0029] Specifically, the driving state includes vehicle speed, turn signal state, and navigation information, and the operation intention includes lane change, turning, and U-turn intentions. The blind area includes at least one of the areas of the left front, left rear, right front, and right rear.

[0030] According to the driving state of the vehicle (such as vehicle speed, turn signal state) and the driver's operation intention (such as lane change, turning, U-turn), determine the blind area to be displayed, including: when it is detected that the left turn signal is turned on, the left front blind area (for judging the situation of pedestrians or non-motor vehicles) and / or the left rear blind area (for detecting lane change risks) can be triggered for display; when it is detected that the right turn signal is turned on, the right front blind area (paying attention to the safety of the non-motor vehicle lane when turning) and / or the right rear blind area (detecting lane change obstacles) can be triggered for display.

[0031] S3. Process the image data of the blind area, including de - distortion and image enhancement.

[0032] Specifically, perform de - distortion processing on the collected image data of the blind area. Correct the image captured by the fisheye camera through an algorithm, transform the curves in the image into straight lines to conform to the driver's visual intuition.

[0033] In some embodiments, the distortion parameters of the fisheye camera (focal length, field of view angle, and image sensor size) can be used to obtain the distortion model of the lens through a calibration process. Then, through a distortion correction algorithm (such as the inverse mapping algorithm based on the pinhole camera model), map the original fisheye image to an orthogonal coordinate system to restore the curves in the image to straight lines. Apply an interpolation algorithm (such as bilinear interpolation or nearest - neighbor interpolation) to resample the pixel values after mapping to generate a de - distorted image, thereby generating an intuitive blind - area image that conforms to the driver's visual intuition.

[0034] In some embodiments, after completing the de - distortion processing, image enhancement processing can be further performed, including enhancing the clarity, contrast, and color saturation of the image so that the driver can more clearly identify obstacles or potential risks.

[0035] In some embodiments, real - time image processing technology can be used to enhance the realism of the distance relationship to ensure that the distances in the image are consistent with the actual environment. In addition, image prompt information can be superimposed, such as highlighting the possible collision risk area or dynamically displaying the position and movement direction of the risk target object, thereby providing more intuitive and accurate blind - area image information for the driver.

[0036] S4. Display the processed blind - area image on the in - vehicle display screen.

[0037] Specifically, display the blind - area image after de - distortion and image enhancement processing on the central control screen or the instrument panel display screen through the in - vehicle information system; according to the driving scenario and user settings, select a suitable display form, such as displaying the blind - area image in a floating window without interfering with the display of navigation or other information.

[0038] For complex scenarios, a stitched image of the left and right blind areas or a panoramic rear - view image can be provided.

[0039] In some embodiments, combined with user - interaction design, the driver can be allowed to click on the floating window to enter the full - screen mode to view a larger range of images to meet the need for a more detailed observation of a specific blind area.

[0040] In some embodiments, dynamic annotation information can be superimposed on the display screen, such as highlighting the risk area or using animation to prompt the lane - change risk, thereby providing clear and easy - to - understand blind - area information for the driver.

[0041] S5. Determine the driver's operation intention and dynamically adjust the displayed blind spot area.

[0042] Specifically, by real-time monitoring the driving state of the vehicle (such as vehicle speed, turn signal state) and the driver's operation intention (such as lane change, turn or U-turn), the displayed blind spot area is dynamically adjusted.

[0043] Further, as an implementation manner of the present invention, in step S2, according to the driving state of the vehicle and the preset user preferences, determine the blind spot area to be displayed, including: According to the preferences set by the user, select different video stream processing methods, and the preferences at least include a first preference and a second preference.

[0044] Among them, the first preference is to display the splicing effect of the side front and side rear images in the corresponding direction according to the turn signal direction, and the second preference is to display the splicing effect of the directly rear and side rear images in the turn signal direction.

[0045] Exemplarily, referring to Figure 2 , when the vehicle blind spot compensation function is turned on, it enters the monitoring state. When the driver turns on the turn signal, the blind spot display content can be determined according to the user's preference settings, providing different blind spot display effects.

[0046] Specifically, if the user selects preference one, the splicing effect of the blind spot images on the side front and side rear of the vehicle is displayed according to the direction of the turn signal to help the driver more intuitively observe the situation on the side of the vehicle; if the user selects preference two, the blind spot splicing images of the directly rear and side rear in the turn signal direction of the vehicle are default displayed from the perspective of the "super rearview mirror" to provide a wider rearview range.

[0047] While the image is being displayed, further determine whether it is necessary to trigger the intelligent assistance function. Specifically include: detecting whether the current condition for triggering the lane change assistance warning is met. If it is met, the display content of the blind spot compensation floating window is dynamically adjusted according to the warning level, including marking potential dangerous targets in the image, thereby helping the driver better judge the surrounding environment and avoiding potential safety risks. At the same time, it can also detect whether direction assistance warning is required. If the triggering condition is met, relevant warning prompts will also be displayed in the floating window to ensure that the driver can timely perceive the dynamic objects in the blind spot.

[0048] Further, as an implementation manner of the present invention, the determining the driver's operation intention and dynamically adjusting the displayed blind spot area includes: when the left turn signal is detected to be turned on, judge the driver's intention according to the vehicle speed and navigation information; if it is judged as a lane change intention, display the left rear blind spot area; if it is judged as a left turn or U-turn intention, display the left front blind spot area.

[0049] When changing lanes to the left, the driver should pay attention to the left rear blind spot to determine whether there is a risk of changing lanes; when turning left or making a U-turn, the vehicle is generally in the leftmost lane. The driver should pay attention to the left front blind spot to determine whether there are people or non-motor vehicles crossing the sidewalk in front, and pay extra attention to the situation in the opposite lane in front when making a U-turn.

[0050] Furthermore, as an embodiment of the present invention, the method of determining the driver's operating intention and dynamically adjusting the displayed blind spot area also includes: displaying the right rear blind spot area when it is detected that the right turn signal is turned on.

[0051] When changing lanes to the right, the driver should pay attention to the right rear blind spot to determine whether there is a risk of changing lanes. When turning right, the vehicle is usually in the rightmost lane, and the driver should pay attention to the right rear blind spot to observe whether there are pedestrians or non-motor vehicles going straight on the right non-motor vehicle lane.

[0052] The reason why the embodiment of the present invention only displays the right rear blind spot area when the right turn signal is turned on is that the driver's demand for rear environment information is more critical in the right turn scenario.

[0053] Specifically, right turns usually involve a smaller turning radius and higher rear risks, especially in scenarios such as lane changes or side parking. The right rear area is the driver's main focus, while the right front area is usually within the driver's direct line of sight or has lower risks. Therefore, prioritizing the display of the right rear blind spot can accurately provide the key information needed by the driver to avoid distraction.

[0054] In addition, the right rear blind spot is usually more likely to hide objects parallel to the vehicle, such as fast-approaching motor vehicles or non-motor vehicles. By only displaying the right rear blind spot, it can help the driver understand the dynamics of the area more clearly, reduce safety hazards caused by obstructed vision or blind spots, and thus improve driving safety.

[0055] This implementation method embodies the principle of priority of information display, that is, highlighting the most important safety information within a limited display space to provide the driver with accurate and effective auxiliary decision support.

[0056] Furthermore, as an embodiment of the present invention, determining the driver's operating intention includes: acquiring lane-level navigation and positioning information of the vehicle; and determining the driver's intention based on the vehicle's lane position and lane travel direction information.

[0057] Specifically, first, through lane-level navigation and positioning functions, the vehicle's real-time location information and the attribute information of the lane it is in are accurately obtained, including lane number, lane width, direction of travel, and whether turning is allowed.

[0058] Combined with the navigation path planning information, determine the relationship between the current lane where the vehicle is located and the navigation target lane, such as whether a lane change or a turn is required. If the driving direction of the lane where the vehicle is located is consistent with the navigation guidance and no lane change is needed, it is determined that the driver's intention is to go straight. If the driving direction of the lane where the vehicle is located is different from the navigation guidance, for example, the navigation prompts a left turn or a U-turn, and the vehicle is in a straight lane, it is determined that the driver may need to change lanes to the left turn or U-turn lane. When the vehicle is in the left turn lane and the navigation prompts a left turn or a U-turn, it is determined that the driver's intention is a left turn or a U-turn.

[0059] By integrating lane-level positioning and navigation information, it is possible to dynamically and accurately determine the driver's operation intention, providing a reliable basis for the subsequent selection of the dynamic display area of the blind spot.

[0060] In some embodiments of the present invention, when the vehicle does not have lane-level navigation and positioning capabilities, the determination of the driver's operation intention includes: obtaining the general navigation information of the vehicle; if the vehicle position is within a predetermined range from the intersection and the navigation guidance information is a left turn or a U-turn, it is determined as a left turn or U-turn intention; otherwise, it is determined as a lane change intention.

[0061] Specifically, when the vehicle does not have lane-level navigation and positioning capabilities, the current position and path guidance information of the vehicle are obtained through the general navigation function, including the distance to the next intersection and the content of the steering guidance.

[0062] First, determine whether the vehicle is approaching the intersection, that is, judge whether the vehicle has entered the predetermined range (for example, the intersection buffer area of 100 meters or 200 meters). If the vehicle has entered this range and the navigation prompts a left turn or a U-turn at the intersection, it is inferred that the driver's operation intention is a left turn or a U-turn. This is because in this scenario, the driver usually adjusts the driving route to complete the turning operation.

[0063] If the vehicle is not approaching the intersection, or is approaching the intersection but the navigation does not indicate a left turn or a U-turn, it is determined that the driver's intention is a lane change intention. In this case, the driver may change lanes only to overtake, avoid, or enter a suitable straight lane.

[0064] By using the general navigation information and the determination of the intersection range, this method can still accurately infer the driver's operation intention without high-precision positioning capabilities, providing support for the dynamic adjustment of the blind spot display area.

[0065] Furthermore, as an embodiment of the present invention, when the vehicle has no navigation information, the determination of the driver's operation intention includes: obtaining the current vehicle speed; if the vehicle speed is less than a predetermined threshold, it is determined as a left turn or U-turn intention; if the vehicle speed is greater than or equal to the predetermined threshold, it is determined as a lane change intention.

[0066] Specifically, when the vehicle cannot obtain navigation information, the driver's operation intention is inferred by real-time monitoring of the vehicle's current speed.

[0067] First, a predetermined speed threshold (e.g., 10 km / h or 15 km / h) is set as the judgment benchmark. When the actual speed of the vehicle is lower than this threshold, it is inferred that the driver may be in a decelerating state, usually corresponding to scenarios of preparing to turn left or make a U-turn, as these operations typically need to be completed at low speeds. On the contrary, when the vehicle speed is greater than or equal to the predetermined threshold, it is judged that the driver is more likely to maintain a certain driving speed for lane changing, such as for overtaking or entering the target lane.

[0068] This method of judging the operation intention through the speed threshold provides a simple and effective way of speculation in the absence of navigation information, provides a basis for the selection of the blind area display area, and at the same time ensures the safety assistance of the driver in different operation scenarios.

[0069] Exemplarily, from the perspective of scenarios, users are concerned about the left front blind area, left rear blind area, and right rear blind area of the left A-pillar. It is reasonable to display the right rear image when turning on the right turn signal. However, when turning on the left turn signal for lane changing, users need to supplement the left rear blind area, and when turning left / making a U-turn, users need to supplement the left front blind area. At this time, it is necessary to combine navigation information to judge the image required by users when turning on the left turn signal. The embodiments of the present invention can adopt different schemes according to the vehicle configuration:

[0070] Configuration 1: If the vehicle has lane-level navigation and positioning capabilities, judge the left front or left rear image when the user turns on the turn signal according to the vehicle's lane position and all lane traffic direction information: If the current lane is going straight, the user needs to change lanes, and turn on the turn signal to display the left rear image; if the current vehicle is turning left, the user needs to turn left or make a U-turn, and turn on the turn signal to display the left front image; Configuration 2: If the vehicle does not have lane-level navigation and positioning capabilities and is only a general navigation, judge the left front or left rear image when the user turns on the turn signal according to the front navigation direction guidance information: If the current vehicle position is within a certain range from the intersection, such as within 20 m, and the navigation guidance information is "turn left / a U-turn ahead", turn on the turn signal to display the left front image; if the above requirements are not met, the default is the side rear blind area image; Configuration 3: If the vehicle does not have lane-level navigation and positioning capabilities and is only a general navigation, but the navigation is not turned on, judge the left front or left rear image when the user turns on the turn signal according to the vehicle speed: If the vehicle speed is less than 15 km / h, turn on the turn signal to display the left front image; if the vehicle speed is greater than 15 km / h, turn on the turn signal to display the left rear image.

[0071] Further, as an implementation manner of the present invention, the blind area display method further includes: receiving a touch operation of the user on the displayed blind area image; in response to the touch operation, displaying a panoramic image including the front left, rear left, front right, and rear right on the vehicle-mounted display screen.

[0072] Specifically, the embodiment of the present invention can receive the touch operation of the user in real time through the touch module of the vehicle-mounted display screen. When the user touches the currently displayed blind area image, the touch instruction is recognized and the panoramic image display mode is triggered.

[0073] Subsequently, the image data resources of the vehicle-mounted camera are called, the real-time image data of the front left, rear left, front right, and rear right are integrated, and the images collected by multiple cameras are fused through a preset stitching algorithm to generate a complete panoramic image.

[0074] To improve the display effect, the panoramic image can also be subjected to de-distortion and image enhancement processing to ensure the clarity and sense of space of the view. In addition, the content of the panoramic image is dynamically adjusted according to the driving state of the vehicle. For example, a wider range of blind area information is preferentially displayed in the stationary state, while the driver's field of view is optimized in the driving state. Finally, the processed panoramic image is displayed in the central view area of the vehicle-mounted display screen, providing intuitive and comprehensive information about the vehicle's surrounding environment for the driver.

[0075] The embodiment of the present invention also discloses a blind area display system.

[0076] Refer to Figure 3 A blind area display system includes an image acquisition module 1, a blind area confirmation module 2, an image processing module 3, a blind area display module 4, and a blind area adjustment module 5.

[0077] The image acquisition module 1 is at least used to acquire the image data around the vehicle.

[0078] Specifically, the image acquisition module 1 collects the image data around the vehicle in real time through the panoramic cameras, circumferential cameras, or single-side cameras installed on the vehicle.

[0079] For vehicles equipped only with panoramic cameras, the image acquisition module 1 calls the video stream of the panoramic cameras to collect the fisheye images of the front left, rear left, front right, and rear right.

[0080] For vehicles equipped with a circumferential vision system at the same time, the image acquisition module 1 can combine multiple cameras to collect more comprehensive image data around the vehicle.

[0081] The blind area confirmation module 2 is at least used to determine the blind area to be displayed according to the driving state of the vehicle and the preset user preferences.

[0082] Specifically, the blind spot confirmation module 2 dynamically determines the blind spot areas to be displayed by monitoring the driving state of the vehicle in real time (such as vehicle speed, steering wheel angle, turn signal), as well as the preset user preferences.

[0083] Specifically, when the turn signal is detected to be on, the blind spot confirmation module 2 selects the corresponding display strategy according to the user preferences. For example, for preference one, it displays the front side and rear side blind spot images, and for preference two, it displays the rear and rear side stitched images.

[0084] The image processing module 3 is at least used to process the image data of the blind spot areas, including de - distortion and image enhancement.

[0085] Specifically, the image processing module 3 processes the acquired image data of the blind spot areas in real time to improve the visual quality and spatial intuitiveness of the images.

[0086] The image processing module 3 performs de - distortion processing on the images collected by the fish - eye camera through a distortion correction algorithm, eliminates the curved surface effect caused by the lens structure, and restores the curved lines in the images to straight lines, so that the images are more in line with human visual habits.

[0087] The image processing module 3 can apply image enhancement technology to optimize the brightness, contrast, and edge sharpness of the images, ensuring that the driver can clearly distinguish obstacles and the surrounding environment under different light conditions (such as at night or in backlight).

[0088] In addition, the image processing module 3 can also overlay dynamic annotation information, such as highlighting potential risk targets or using animation effects to annotate the movement trajectories of the targets.

[0089] In complex scenarios, the image processing module 3 integrates the images from multiple cameras into a panoramic view through a stitching algorithm to ensure the integrity and consistency of the field of view.

[0090] The image processing module 3 provides clear and intuitive image support for subsequent blind spot display through real - time and efficient image processing.

[0091] The blind spot display module 4 is at least used to display the processed blind spot images on the in - vehicle display screen.

[0092] Specifically, the blind spot display module 4 displays the optimized blind spot images from the image processing module 3 on the in - vehicle display screen in real time.

[0093] The display form can be dynamically adjusted according to user preferences and driving needs. For example, it displays the single - side blind spot image in the form of a floating window to avoid blocking navigation or other central control screen information; when a panoramic view is needed, it displays the stitched images of the left, right, front, and rear blind spots in full - screen mode.

[0094] To enhance the driver's intuitive experience, the blind spot display module 4 can also overlay dynamic prompt information, such as marking the potential collision risk area or highlighting the position and direction of the moving target.

[0095] The blind spot display module 4 also supports user touch operations. By clicking on a specific area, the driver can enter the panoramic view to view a larger range of images, thereby enhancing driving safety and convenience.

[0096] The blind spot adjustment module 5 is at least used to judge the driver's operation intention and dynamically adjust the displayed blind spot area.

[0097] Specifically, the blind spot adjustment module 5 dynamically adjusts the display area of the blind spot image according to the vehicle's real-time driving state (such as vehicle speed, steering wheel angle, turn signal) and the driver's operation intention (such as lane change, turn or U-turn).

[0098] The blind spot adjustment module 5 first judges the driver's specific intention by analyzing the turning direction of the turn signal and the vehicle's current navigation information. For example, when the left turn signal is on and the navigation prompts a left turn or U-turn, the blind spot adjustment module 5 preferentially selects to display the left front blind spot; if the vehicle is driving at a high speed and intends to change lanes, it displays the left or right rear blind spot. For vehicles without navigation capabilities, the blind spot adjustment module 5 uses a speed threshold to infer the intention: low speed corresponds to turning or U-turn, and high speed corresponds to lane change. Through these adjustment mechanisms, the module realizes the intelligent optimization of blind spot display, improving driving safety and driving experience.
