Abstract
Description
Technical Field
[0001] The present application belongs to the field of automotive electronics technology, and specifically relates to a vehicle-mounted head-up display control method, system, and device. Background Art
[0002] With the widespread adoption of automotive HUD (Head-Up Display) technology, drivers can access critical driving information without looking down, improving driving safety and convenience. However, for some patients with eye diseases, such as presbyopia and hyperopia, the dynamic vision of presbyopia can lead to slower focusing speed, inflexible focus switching, and increased visual fatigue. This can cause the driver to take longer to focus when switching from distant road conditions to nearby HUD content. Furthermore, the need to frequently switch focus in the driving environment can lead to an unsmooth switching process due to the reduced ability of the eyes to adjust, resulting in brief visual blur. This makes it difficult to quickly and clearly identify nearby HUD content, which not only affects the driving experience but can also affect driving safety. Summary of the Invention
[0003] In order to solve the above technical problems, the present application proposes a vehicle-mounted head-up display control method, system and device that can evaluate whether the driver is an eye disease patient based on the driver's visual focus time and focus stabilization time, and adjust the display parameters of the vehicle-mounted head-up display according to the evaluation results.
[0004] Specifically, the present application proposes a vehicle head-up display control method, comprising: The driver's final visual focusing time and final focusing stabilization time are collected in real time.
[0005] The final visual focus time and the final focus stabilization time are evaluated based on a preset visual focus time range and a preset focus stabilization time range to obtain a visual focus time evaluation result and a focus stabilization time evaluation result.
[0006] A final evaluation result is obtained based on the visual focusing time evaluation result and the focus stabilization time evaluation result.
[0007] And, adjusting display parameters of the vehicle head-up display in real time based on the final evaluation result.
[0008] In the above technical solution, by collecting the driver's final visual focus time and final focus stabilization time and evaluating them, it is possible to effectively assess whether the driver's visual state is normal. By obtaining a final evaluation result based on the visual focus time evaluation results and the focus stabilization time evaluation results, the accuracy of the driver's visual state detection is effectively ensured, improving the reliability of the final evaluation result. If the driver is determined to be presbyopic, the display parameters of the vehicle's head-up display are automatically adjusted to enable the presbyopic patient to clearly see the interface elements of the vehicle's head-up display, thereby improving driving safety and comfort.
[0009] As an embodiment, the real-time acquisition of the driver's final visual focus time and final focus stabilization time includes: The driver's visual motion state is collected in real time based on an eye tracking device; and the final visual focusing time and the final focusing stabilization time are obtained based on the visual motion state.
[0010] The eye tracking device can capture the driver's eye movements in real time, accurately identify the driver's visual focus and gaze duration, and reduce the error of visual motion state detection.
[0011] Furthermore, the obtaining of the final visual focus time and the final focus stabilization time based on the visual motion state further includes: An initial visual focusing time and an initial focusing stabilization time of preset values are obtained based on the visual motion state.
[0012] Data filtering and averaging are performed on the initial visual focusing time and the initial focusing stabilization time to obtain the final visual focusing time and the final focusing stabilization time.
[0013] By filtering the initial visual focus time and initial focus stabilization time, eye data jitter caused by environmental factors such as road bumps, slight head movements, and ambient lighting is eliminated, effectively reducing errors in the visual focus and focus stabilization times. Averaging reduces the effects of sudden strong light hitting the pupil or momentary interference from eyeglass reflections, ensuring the stability and reliability of the final visual focus and focus stabilization times.
[0014] Furthermore, the final visual focus time includes at least a first visual focus time from far to near and a second visual focus time from near to far; the preset visual focus time range includes at least a first preset visual focus time range and a second preset visual focus time range; and the evaluating the final visual focus time and the final focus stabilization time based on the preset visual focus time range and the preset focus stabilization time range includes: evaluating the first visual focus time based on a first preset visual focus time range, so that when the first visual focus time is within the first preset visual focus time range, determining that a first evaluation result is a normal state; otherwise, determining that the first evaluation result is an abnormal state; The second visual focus time is evaluated based on a second preset visual focus time range, so that when the second visual focus time is within the second preset visual focus time range, the second evaluation result is determined to be a normal state; otherwise, the second evaluation result is determined to be an abnormal state.
[0015] The first visual focusing time from far to near and the second visual focusing time from near to far are evaluated separately, so as to evaluate the driver's visual state more finely, thereby making the subsequent evaluation result of whether the driver is a presbyopic patient more accurate.
[0016] Furthermore, the evaluating the final visual focus time and the final focus stabilization time based on the preset visual focus time range and the preset focus stabilization time range further includes: The first evaluation result and the second evaluation result are compared. If both the first evaluation result and the second evaluation result are normal, it is determined that the evaluation result of the driver's visual focus time is normal.
[0017] Otherwise, if both the first evaluation result and the second evaluation result are abnormal, it is determined that the visual focus time evaluation result is abnormal.
[0018] If the first evaluation result and the second evaluation result are inconsistent, it is determined that the evaluation data is incorrect, and the data is collected again for evaluation.
[0019] The visual focus time evaluation result is considered normal only when both the first evaluation result for the first visual focus time from far to near and the second evaluation result for the second visual focus time from near to far are normal, effectively avoiding misjudgments caused by single data anomalies. If one direction is abnormal, data is re-collected and evaluated, effectively preventing misjudgments caused by brief interference.
[0020] Furthermore, the evaluating the final visual focus time and the final focus stabilization time based on the preset visual focus time range and the preset focus stabilization time range further includes: The final focus stabilization time is evaluated based on a preset focus stabilization time range. If the final focus stabilization time is within the preset focus stabilization time range, it is determined that the focus stabilization time evaluation result is a normal state.
[0021] Otherwise, it is determined that the focus stabilization time evaluation result is in an abnormal state.
[0022] By evaluating the visual focusing time and the focusing stabilization time, the comprehensiveness of the driver's visual state monitoring is enhanced.
[0023] Furthermore, obtaining the final evaluation result includes: When the visual focusing time evaluation result and the focus stabilization time evaluation result are both in normal state, it is determined that the final evaluation result is in normal state.
[0024] When both the visual focusing time evaluation result and the focus stabilization time evaluation result are in abnormal states, it is determined that the final evaluation result is in an abnormal state.
[0025] When the visual focusing time evaluation result and the focus stabilization time evaluation result are inconsistent, it is determined that the evaluation data is incorrect, and the data is re-collected for evaluation.
[0026] The driver's vision is considered normal only if and only if the evaluation results of both the visual focus time and the focus stabilization time are normal. The driver's vision is considered abnormal only if and only if the evaluation results of both the visual focus time and the focus stabilization time are abnormal. In other words, the driver is determined to be presbyopic, further ensuring the accuracy and reliability of the evaluation results.
[0027] Furthermore, the real-time adjustment of display parameters of the vehicle head-up display based on the final evaluation result includes: When the final evaluation result is normal, the head-up display is controlled to display normally.
[0028] When the final evaluation result is an abnormal state, each display parameter in the vehicle-mounted head-up display is adjusted to a corresponding preset parameter threshold.
[0029] When the final evaluation result is an abnormal state, that is, when the driver is determined to be a presbyopic patient, various display parameters in the vehicle-mounted head-up display are adjusted so that the vehicle-mounted head-up display can adapt to the driver's visual state, thereby effectively improving the driver's driving experience and improving the driver's driving safety.
[0030] Based on the same inventive concept, the present application also proposes a system for controlling a vehicle-mounted head-up display, the system comprising: The data acquisition module is used to collect the driver's final visual focus time and final focus stabilization time in real time.
[0031] The time evaluation module is used to evaluate the final visual focus time and the final focus stabilization time based on a preset visual focus time range and a preset focus stabilization time range to obtain a visual focus time evaluation result and a focus stabilization time evaluation result.
[0032] A result evaluation module is used to obtain a final evaluation result based on the visual focus time evaluation result and the focus stabilization time evaluation result.
[0033] And, a display adjustment module is used to adjust the display parameters of the vehicle head-up display in real time based on the final evaluation result.
[0034] Based on the same inventive concept, the present application also proposes a computer device, including a processor and a memory, wherein the memory stores computer-executable instructions, and the computer-executable instructions can be read by the processor and execute the vehicle-mounted head-up display control method.
[0035] Compared with the prior art, this application has at least the following beneficial effects: The present application effectively solves the technical problem that some patients with eye diseases, such as presbyopia, have difficulty in quickly and clearly identifying the contents of the head-up display in the vehicle nearby due to slow visual focusing speed and inflexible focus switching during driving, resulting in a poor driving experience and affecting driving safety. By collecting the driver's final visual focus time and final focus stabilization time, and by evaluating the final visual focus time and final focus stabilization time, it is possible to effectively evaluate whether the driver's visual state is normal. By obtaining the final evaluation result based on the visual focus time evaluation result and the focus stabilization time evaluation result, it is possible to effectively ensure the accuracy of the driver's visual state detection and improve the reliability of the final evaluation result. When it is determined that the driver is a presbyopia patient, the display parameters of the vehicle-mounted head-up display are automatically adjusted so that the presbyopia patient can clearly see the interface elements of the vehicle-mounted head-up display, thereby improving driving safety and comfort. BRIEF DESCRIPTION OF THE DRAWINGS
[0036] Figure 1 This is a flow chart of a vehicle head-up display control method shown in an embodiment of the present application.
[0037] Figure 2 Schematic diagram of a vehicle-mounted head-up display control system shown in an embodiment of the present application. DETAILED DESCRIPTION
[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices. Example 1:
[0040] Please refer to Figure 1 The vehicle head-up display control method mainly includes steps S100 to S400.
[0041] Wherein, the step S100 includes: collecting the driver's final visual focus time and final focus stabilization time in real time. A DMS (Driver Monitoring System) eye tracker can be mainly used to monitor the driver's line of sight movement in real time. The DMS eye tracker tracks the driver's eye movement trajectory in real time, and collects the final visual focus time and final focus stabilization time based on the line of sight focus point and focus stabilization time in the eye movement trajectory. The process of collecting the final visual focus time and the final focus stabilization time can also include data filtering and averaging processing of the initially collected initial visual focus time and initial focus stabilization time to ensure the accuracy and reliability of the obtained final visual focus time and final focus stabilization time.
[0042] Step S200 includes: evaluating the final visual focus time and the final focus stabilization time based on a preset visual focus time range and a preset focus stabilization time range to obtain a visual focus time evaluation result and a focus stabilization time evaluation result. When detecting whether a driver is presbyopic, since the visual focusing time range for a normal person from far to near is generally 0.1-0.5 seconds, the visual focusing time range from near to far is generally 0.1-0.3 seconds, and the focusing stabilization time range is generally 0.5-1.5 seconds, a first preset visual focusing time range from far to near can be set to 0.1-0.5 seconds, a second preset visual focusing time range from near to far can be set to 0.1-0.3 seconds, and a preset focusing stabilization time range can be set to 0.1-1.5 seconds. When the detected final visual focusing time and final focusing stabilization time are not within the set ranges, that is, when the visual focusing time from far to near is greater than 0.5 seconds, the visual focusing time from near to far is greater than 0.3 seconds, and the focusing stabilization time is greater than 1.5 seconds, the driver is determined to be presbyopic. Those skilled in the art may adjust the preset visual focusing time range and the preset focusing stabilization time range according to actual circumstances, and are not limited to this.
[0043] Step S300 includes obtaining a final evaluation result based on the visual focus time evaluation result and the focus stabilization time evaluation result. The driver's visual state is determined to be abnormal only if both the visual focus time evaluation result and the focus stabilization time evaluation result are abnormal, thereby improving the accuracy of the driver's visual state evaluation result. If the visual focus time evaluation result and the focus stabilization time evaluation result are inconsistent, it indicates that the collected data may be incorrect, and re-collection of data is required.
[0044] Furthermore, step S400 includes adjusting display parameters of the vehicle head-up display in real time based on the final evaluation result. The display parameters of the vehicle head-up display to be adjusted may include at least brightness and contrast of the interface, interface fonts and icons, interface color saturation, and depth of field of displayed content.
[0045] During the specific implementation process, when it is necessary to detect whether the driver is a presbyopic patient and thus adaptively adjust the display parameters of the vehicle head-up display, based on the difference in visual focusing time and focusing stabilization time between normal people and presbyopic patients, the first preset visual focusing time range from far to near is set to 0.1-0.5s, the second preset visual focusing time range from near to far is set to 0.1-0.3s, and the preset focusing stabilization time range is set to 0.5-1.5s. After the driver gets on the car, the driver's initial visual focusing time and initial focusing stabilization time are collected in real time through the DMS eye tracker, and the collected initial focusing time and initial focusing stabilization time are filtered and averaged. The final visual focus time and the final focus stabilization time are obtained, and the final visual focus time and the final focus stabilization time are evaluated based on the preset visual focus time range and the preset focus stabilization time range to obtain a visual focus time evaluation result and a focus stabilization time evaluation result, and then the final evaluation result is obtained based on the visual focus time evaluation result and the focus stabilization time evaluation result. When the final evaluation result is that the driver is a presbyopic patient, the brightness and contrast of the vehicle-mounted head-up display are improved, the interface font icons are increased, the interface color saturation is increased, the depth of field of the vehicle-mounted head-up display content is increased, etc., to adapt to presbyopic patients, so that presbyopic patients can quickly see the content of the vehicle-mounted head-up display.
[0046] In some embodiments, the real-time acquisition of the driver's final visual focus time and final focus stabilization time includes: The visual motion state of the driver is collected in real time based on the eye tracking device, and the final visual focusing time and the final focusing stabilization time are obtained based on the visual motion state.
[0047] The eye tracking device may at least be a DMS eye tracker, which tracks the driver's eye movement trajectory in real time, thereby collecting the driver's visual focus time and focus stabilization time based on the eye movement trajectory.
[0048] Optionally, the acquiring the final visual focus time and the final focus stabilization time based on the visual motion state further includes: An initial visual focusing time and an initial focusing stabilization time of preset values are obtained based on the visual motion state.
[0049] Data filtering and averaging are performed on the initial visual focusing time and the initial focusing stabilization time to obtain the final visual focusing time and the final focusing stabilization time.
[0050] The visual motion state may include at least eye movement trajectory, changes in gaze point, gaze duration, etc. An eye tracker may be used to capture the driver's eye movement trajectory and focus area to record the visual motion state in detail. The data filtering process may include data cleaning and filtering to remove irrelevant noise or unreasonable data.
[0051] Optionally, the final visual focus time includes at least a first visual focus time from far to near and a second visual focus time from near to far; the preset visual focus time range includes at least a first preset visual focus time range and a second preset visual focus time range; and the evaluating the final visual focus time and the final focus stabilization time based on the preset visual focus time range and the preset focus stabilization time range includes: The first visual focus time is evaluated based on a first preset visual focus time range, so that when the first visual focus time is within the first preset visual focus time range, a first evaluation result is determined to be a normal state; otherwise, the first evaluation result is determined to be an abnormal state.
[0052] The second visual focus time is evaluated based on a second preset visual focus time range, so that when the second visual focus time is within the second preset visual focus time range, the second evaluation result is determined to be a normal state; otherwise, the second evaluation result is determined to be an abnormal state.
[0053] Among them, the first visual focusing time is the visual focusing process from far to near, and the second visual focusing time is the visual focusing process from near to far. The first visual focusing time range can be set to 0.1-0.5s. Since the visual focusing time of normal people and patients with eye diseases is different, the visual focusing time of patients with eye diseases is longer than that of normal people. That is, when the first visual focusing time is greater than 0.5s, the first evaluation result is determined to be that the first visual focusing time is not the visual focusing time of a normal person, that is, the first evaluation result is an abnormal state. The second visual focusing time range can be set to 0.1-0.3s. If the second visual focusing time is within the second visual focusing time range, the second evaluation result is determined to be a normal state; otherwise, the second evaluation result is determined to be an abnormal state.
[0054] Optionally, the evaluating the final visual focus time and the final focus stabilization time based on a preset visual focus time range and a preset focus stabilization time range further includes: The first evaluation result and the second evaluation result are compared. If both the first evaluation result and the second evaluation result are normal, it is determined that the evaluation result of the driver's visual focus time is normal.
[0055] Otherwise, if both the first evaluation result and the second evaluation result are abnormal, it is determined that the visual focus time evaluation result is abnormal.
[0056] If the first evaluation result and the second evaluation result are inconsistent, it is determined that the evaluation data is incorrect, and the data is collected again for evaluation.
[0057] For example, the first visual focus time range is set to 0.1-0.5s, and the second visual focus time range is 0.1-0.3s. Assuming that the first visual focus time of the detected driver is 0.4s and the second visual focus time is 0.4s, that is, the first evaluation result is normal and the second evaluation result is abnormal, it is determined that the collected data may be wrong, and the data needs to be re-collected for evaluation.
[0058] Optionally, the evaluating the final visual focus time and the final focus stabilization time based on a preset visual focus time range and a preset focus stabilization time range further includes: The final focus stabilization time is evaluated based on a preset focus stabilization time range. If the final focus stabilization time is within the preset focus stabilization time range, the focus stabilization time evaluation result is determined to be a normal state; otherwise, the focus stabilization time evaluation result is determined to be an abnormal state.
[0059] The preset focus stabilization time range can be set to 0.5s to 1.5s. For example, if the final focus stabilization time is 1.6s, the final focus stabilization time is not within the preset focus stabilization time range, indicating that the focus stabilization time evaluation result is abnormal.
[0060] Optionally, obtaining the final evaluation result includes: When the visual focusing time evaluation result and the focus stabilization time evaluation result are both in normal state, it is determined that the final evaluation result is in normal state.
[0061] When both the visual focusing time evaluation result and the focus stabilization time evaluation result are in abnormal states, it is determined that the final evaluation result is in an abnormal state.
[0062] When the visual focusing time evaluation result and the focus stabilization time evaluation result are inconsistent, it is determined that the evaluation data is incorrect, and the data is re-collected for evaluation.
[0063] During the specific implementation process, in order to ensure the accuracy of the final evaluation results of the driver's visual state, the final evaluation results are judged only when the visual focus time evaluation results and the focus stabilization time evaluation results are consistent. If the visual focus time evaluation results and the focus stabilization time evaluation results are inconsistent, it may be due to complex environments, such as strong light interference environments at night. Due to various strong light interference factors, the driver's visual focus time is unstable, resulting in inconsistency between the two evaluation results. At this time, it is necessary to re-collect data for re-evaluation until the two evaluation results are consistent, so as to judge the final evaluation result.
[0064] Optionally, adjusting display parameters of an in-vehicle head-up display in real time based on the final evaluation result includes: When the final evaluation result is normal, the head-up display is controlled to display normally.
[0065] When the final evaluation result is an abnormal state, each display parameter in the vehicle-mounted head-up display is adjusted to a corresponding preset parameter threshold.
[0066] When the final evaluation result is normal, it means that the driver's vision is normal, and the head-up display is controlled to display normally; if the final evaluation result is abnormal, it means that the driver is an eye disease patient, such as a presbyopia patient. Based on the fact that the driver is a presbyopia patient, in order to make the on-board head-up display content adapt to the driver's vision, various display parameters in the on-board head-up display are actively controlled, such as enlarging various icons on the head-up display, increasing the saturation of the display content, etc., so that the presbyopia patient can see the display content quickly and clearly, thereby improving driving safety. Example 2:
[0067] Please refer to Figure 2 The present application also proposes a system that adopts the vehicle-mounted head-up display control method described in Example 1, and the system includes: a data acquisition module, a time evaluation module, a result evaluation module, and a display adjustment module.
[0068] The data acquisition module is configured to collect the driver's final visual focus time and final focus stabilization time in real time. The data acquisition module may also include a data processing module configured to perform preliminary data processing on the collected initial visual focus time and final focus stabilization time to improve the accuracy and reliability of the final visual focus time and final focus stabilization time. Data processing methods such as data filtering and data averaging can be used to process the initially collected initial visual focus time and focus stabilization time.
[0069] The time evaluation module is configured to evaluate the final visual focus time and the final focus stabilization time based on a preset visual focus time range and a preset focus stabilization time range to obtain a visual focus time evaluation result and a focus stabilization time evaluation result. The driver's visual focus time can be determined primarily based on two focusing modes, namely, from far to near and from near to far, of the driver's line of sight. During the specific evaluation process, the visual focus time evaluation result is determined only if the visual focus time evaluation result from far to near and the visual focus time evaluation result from far to near are consistent.
[0070] The result evaluation module is configured to obtain a final evaluation result based on the visual focus time evaluation result and the focus stabilization time evaluation result. If both the visual focus time evaluation result and the focus stabilization time evaluation result are abnormal, it indicates that the driver suffers from an eye disease, such as presbyopia, and the vehicle head-up display is adjusted accordingly.
[0071] Furthermore, a display adjustment module is configured to adjust the display parameters of the vehicle's head-up display in real time based on the final evaluation result. To enable patients with eye diseases, such as presbyopia, to quickly and clearly see the content displayed on the vehicle's head-up display, if a driver is identified as having presbyopia, the vehicle's head-up display parameters, such as icons and color saturation, can be adjusted to suit the driver's visual state, thereby improving driving safety and comfort. Example 3:
[0072] The present application also proposes a computer device, which includes at least a processor and a memory, wherein the memory stores computer-executable instructions.
[0073] When the computer executable instructions are executed by the processor, the vehicle-mounted head-up display control method described in Example 1 is implemented.
[0074] In the computer device, it can be implemented in whole or in part by software, hardware, firmware or any combination thereof. When implemented using software, it can be implemented in whole or in part in the form of a computer program product. The computer program product includes one or more computer instructions. When the computer program instructions are loaded and executed on a computer, the process or function described in the embodiment of the present application is generated in whole or in part. The computer can be a general-purpose computer, a special-purpose computer, a computer network, or other programmable device. The computer instructions can be stored in a computer-readable storage medium or transmitted from one computer-readable storage medium to another computer-readable storage medium. For example, the computer instructions can be transmitted from one website, computer, server or data center to another website, computer, server or data center via a wired (e.g., coaxial cable, optical fiber, digital subscriber line) or wireless (e.g., infrared, wireless, microwave, etc.) method. The computer-readable storage medium can be any available medium that a computer can access or a data storage device such as a server or data center that includes one or more available media integrated. The available medium can be a magnetic medium (e.g., a floppy disk, a hard disk, a tape), an optical medium (e.g., a DVD), or a semiconductor medium (e.g., a solid-state drive SolidState Disk (SSD)).
[0075] In summary, the present application effectively solves the technical problem that some patients with eye diseases, such as presbyopia, have difficulty in quickly and clearly identifying the content of the head-up display in the vehicle nearby due to slow visual focusing speed and inflexible focus switching during driving, resulting in a poor driving experience and affecting driving safety. By collecting the driver's final visual focus time and final focus stabilization time, and by evaluating the final visual focus time and final focus stabilization time, it is possible to effectively evaluate whether the driver's visual state is normal. By obtaining the final evaluation result based on the visual focus time evaluation result and the focus stabilization time evaluation result, it is possible to effectively ensure the accuracy of the driver's visual state detection and improve the reliability of the final evaluation result. When it is determined that the driver is a presbyopia patient, the display parameters of the vehicle-mounted head-up display are automatically adjusted so that the presbyopia patient can clearly see the interface elements of the vehicle-mounted head-up display, thereby improving driving safety and comfort.
