Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0026] The following description, with reference to the accompanying drawings, describes a vehicle projection device and method according to embodiments of this application. Addressing the issues mentioned in the background art, such as the high functional requirements of HUD placement leading to situations where some vehicles cannot function properly, and the ease with which the display image, projected onto the windshield, can obstruct the driver's view, hindering accurate adjustments based on the driver's intentions and increasing safety hazards, as well as high maintenance costs, this application provides a vehicle projection device. This device can determine the driver's actual line of sight by recognizing their head posture and switch the projector's projection position based on the actual line of sight and the projector's projection light, thereby ensuring that the actual line of sight and the projection light do not intersect. It can accurately adjust the projection according to the driver's intentions, thus avoiding obstruction of the driver's view, improving vehicle safety, and making the device more intelligent. Therefore, this solves the problems of the high functional requirements of HUD placement leading to situations where some vehicles cannot function properly, and the ease with which the display image, projected onto the windshield, can obstruct the driver's view, hindering accurate adjustments based on the driver's intentions, increasing safety hazards, and high maintenance costs.
[0027] Specifically, Figure 1 This is a schematic diagram of the structure of a vehicle projection device provided in an embodiment of this application.
[0028] Figure 1 This is a schematic diagram of the structure of the projection device for a vehicle according to an embodiment of this application.
[0029] like Figure 1 As shown, the projection device 10 of the vehicle includes: a projector 100, a recognition component 200, and a control component 300.
[0030] Specifically, the projector 100, installed on the rear frame of the front door, is used to project at least one user-required parameter of the vehicle onto the projection position of the windshield.
[0031] It is understood that, in this embodiment of the application, the projector 100 can be installed on the rear frame of the front door on the driver's side so as to project the parameters required by the user onto the windshield. The parameters required by the user can be sent to the projector 100 to ensure that the projector 100 projects the real-time vehicle parameter information required by the user, such as vehicle speed, RPM, fuel consumption, navigation information, etc., so as to display the parameters required by the user on the windshield for the driver to view without having to look down or turn their head to observe the instrument panel or other positions, thereby improving driving safety.
[0032] The recognition component 200 is used to recognize the driver's head posture and determine the driver's actual line of sight based on the head posture.
[0033] It is understood that in the embodiments of this application, the recognition component 200 can capture the driver's head posture to obtain motion parameters such as the angle, tilt and rotation of the driver's head, thereby determining the direction and angle of the driver's actual line of sight from the motion parameters of the driver's head, that is, confirming the driver's actual line of sight.
[0034] Optionally, in one embodiment of this application, the recognition component 200 includes: at least one camera for acquiring multiple head images of the driver; and an extraction unit for extracting at least one posture feature of the driver based on the multiple head images to generate a head posture based on the at least one posture feature.
[0035] It is understood that, in this embodiment of the application, the camera of the recognition component 200 can be installed in an appropriate location inside the vehicle, such as in front of the driver or near the steering wheel, to ensure accurate capture of the driver's head posture. The extraction unit can use head images of the driver captured by multiple cameras, and can extract at least one posture feature of the driver based on image processing and computer vision algorithms, such as using parameters such as the angle, tilt, and rotation of the driver's head to extract the driver's head movement as a posture feature.
[0036] For example, the recognition component 200 can acquire head images in real time, extract posture features and generate head posture to ensure accurate and timely recognition of the driver's head posture, and provide timely feedback and response to the vehicle system.
[0037] This application utilizes at least one camera to capture multiple head images of the driver, and an extraction unit extracts at least one pose feature of the driver based on the multiple head images to generate a head pose. By using multiple head images of the driver captured by the camera to accurately capture the driver's head pose, the accuracy of driver head pose recognition is improved.
[0038] The control component 300 is used to determine whether the actual line of sight and the projection light of the projector 100 meet the preset switching conditions, and if the preset switching conditions are met, to switch the projection position to the anti-interference projection position, or to turn off the projector 100 so that the actual line of sight and the projection light do not intersect.
[0039] It should be noted that the preset switching conditions can be set by those skilled in the art according to the actual situation, and no specific limitations are made here.
[0040] It is understood that, in this embodiment, based on the driver's actual line of sight obtained by the recognition component 200, the system can determine whether the position and direction of the driver's actual line of sight and the projected light from the projector 100 meet preset switching conditions. Specifically, it can determine whether the driver's actual line of sight and the projected light have an intersecting area in space. If they intersect, the system calculates the driver's anti-interference projection position and switches the projection position to the anti-interference projection position, ensuring that the actual line of sight and the projected light do not intersect. Alternatively, based on the actual situation of the anti-interference projection position, the system can determine whether to turn off the projector 100, thereby further ensuring clear driver vision and avoiding visual interference caused by projection, which could increase driving risks.
[0041] Optionally, in one embodiment of this application, the control component 300 is further configured to determine the anti-interference projection position based on the driver's actual line of sight.
[0042] In actual operation, the control component 300 can obtain the anti-interference projection position corresponding to the current actual line of sight by the relative position and direction of the driver's actual line of sight and the projection light of the projector 100. The anti-interference projection position is within the projection range of the vehicle's windshield.
[0043] This application embodiment can determine the anti-interference projection position based on the driver's actual line of sight, which can more accurately meet the driver's needs, realize real-time judgment and switching, ensure the accuracy and real-time performance of the projection position, and improve the driver's comfort and safety.
[0044] Optionally, in one embodiment of this application, the control component 300 is specifically used to determine the weights of multiple calibrated anti-interference projection positions based on the driver's actual line of sight, and to obtain the anti-interference projection position based on the weights of the multiple calibrated anti-interference projection positions.
[0045] In some embodiments, the control component 300 can adjust the weights of different anti-interference projection positions according to the driver's personalized preferences. For example, if the driver is more focused on the road ahead, the weight of the forward position can be reduced to decrease interference from the projection and further improve the driver's concentration on the road. Alternatively, the weights of the calibrated anti-interference projection positions can be dynamically adjusted by monitoring the driver's fatigue level, attention level, and other indicators in real time. For example, when the driver's fatigue level increases, the weight of the side position can be increased to reduce the safety risks that may be caused by fatigued driving. Or, the weights of the calibrated anti-interference projection positions can be adjusted according to changes in the driving environment and road conditions. For example, when driving at night, the weight of the forward position can be increased to avoid interference from vehicles behind, further improving the safety and comfort of night driving.
[0046] The embodiments of this application can determine the optimal anti-interference projection position based on the weights of multiple calibrated anti-interference projection positions, which can minimize the interference of factors on the driver and further improve the driver's concentration and driving safety.
[0047] Optionally, in one embodiment of this application, the control component 300 includes: a detection unit for detecting whether the anti-interference projection position meets the preset shutdown conditions; and a control unit for turning off the projector 100 when the anti-interference projection position is detected to meet the preset shutdown conditions.
[0048] It should be noted that the preset shutdown conditions can be set by those skilled in the art according to the actual situation, and no specific limitations are made here.
[0049] Specifically, if the detection unit of the control component 300 determines that the anti-interference projection position, obtained based on the actual line of sight and the projector's projection light, cannot achieve anti-interference operation, it considers that the anti-interference projection position meets the preset shutdown condition, meaning that the projector's projection light affects the actual line of sight. In this case, the control unit shuts down the projector 100 to prevent the user's side view from being affected. Alternatively, the control component 300 can also determine that the anti-interference projection position meets the preset shutdown condition after sensing the presence of interfering factors in the surrounding environment, such as strong light or reflections, and further shut down the projector 100. For example, when encountering strong sunlight or strong headlight interference from other vehicles, the projector 100 can be automatically shut down to avoid interfering with the driver's side view.
[0050] For example, such as Figure 2-3 The images shown are a side view of the installation location of the projector 100 in the vehicle and a front view of the installation location of the projector 100 in the vehicle, including: projector 100, camera 210, windshield 11 and front door 12.
[0051] When the image is projected onto the vehicle's windshield 11, the projector 100 activates its projection function. Figure 2 The imaging area within the dashed frame in the windshield 11 is projected. When the driver's gaze shifts due to a need to check the side mirror, the camera 210 detects the change in the driver's head movement, and the projector 100 automatically shuts off.
[0052] This application can turn off the projector 100 when the preset switching conditions are not met, thereby protecting the driver's side view in a more intelligent and personalized way, improving driving safety and comfort, ensuring timely handling of interference situations, and improving practicality and efficiency.
[0053] The vehicle projection device proposed in this application can determine the driver's actual line of sight by recognizing the driver's head posture, and switch the projection position of the projector according to the actual line of sight and the projection light of the projector, thereby ensuring that the actual line of sight and the projection light do not intersect. It can accurately adjust the projection according to the driver's actual intention, thus avoiding obstruction of the driver's view, improving vehicle safety, and making the device more intelligent. This solves the problems of HUD placement requiring high vehicle functionality, resulting in some vehicles not being able to use it normally, and the display image easily obstructing the driver's view after being projected onto the windshield, making it impossible to accurately adjust according to the driver's actual intention, increasing safety hazards for passengers, and high maintenance costs.
[0054] Next, the vehicle projection method according to the embodiments of this application is described with reference to the accompanying drawings.
[0055] like Figure 4 As shown, the projection method for this vehicle includes the following steps:
[0056] In step S401, the driver's head posture is identified.
[0057] In step S402, the driver's actual line of sight is determined based on the head posture, and it is determined whether the actual line of sight and the projected light from the projector meet the preset switching conditions.
[0058] In step S403, if the projection light of the projector meets the preset switching conditions, the projection position is switched to the anti-interference projection position, or the projector is turned off, so that the actual line of sight and the projection light do not intersect.
[0059] Optionally, in one embodiment of this application, switching the projection position to an anti-interference projection position includes: determining the anti-interference projection position based on the driver's actual line of sight.
[0060] Optionally, in one embodiment of this application, determining the anti-interference projection position based on the driver's actual line of sight includes: determining the weights of multiple calibrated anti-interference projection positions based on the driver's actual line of sight, and obtaining the anti-interference projection position based on the weights of the multiple calibrated anti-interference projection positions.
[0061] Optionally, in one embodiment of this application, identifying the driver's head pose includes: acquiring multiple head images of the driver; extracting at least one pose feature of the driver based on the multiple head images, so as to generate a head pose based on the at least one pose feature.
[0062] Optionally, in one embodiment of this application, switching the projection position to an anti-interference projection position, or turning off the projector so that the actual line of sight does not intersect with the projected light, includes: detecting whether the anti-interference projection position meets a preset shutdown condition; and turning off the projector if the anti-interference projection position meets the preset shutdown condition.
[0063] It should be noted that the foregoing explanation of the vehicle projection device embodiment also applies to the vehicle projection method of this embodiment, and will not be repeated here.
[0064] The vehicle projection method proposed in this application can determine the driver's actual line of sight by recognizing the driver's head posture, and switch the projection position of the projector according to the actual line of sight and the projection light of the projector, thereby ensuring that the actual line of sight and the projection light do not intersect. This allows for accurate projection adjustment according to the driver's actual intention, avoiding obstruction of the driver's view, improving vehicle safety, and making the system more intelligent. This solves the problems of HUD placement requiring high vehicle functionality, resulting in some vehicles not being able to use it normally, and the display image easily obstructing the driver's view after being projected onto the windshield, making accurate adjustment according to the driver's actual intention impossible, increasing safety hazards for passengers, and high maintenance costs.
