[0049] Step S104, determining distance information between a preset part of the target object and a first preset plane based on the feature data, wherein the first preset plane is a plane where the vehicle is currently traveling.

[0050] The preset parts in the above steps are used to describe one or more specific parts on the target object that are pre-set as reference points. The types of preset parts may include but are not limited to the pupil, nose and mouth of the target object. The specific preset parts need to be determined according to actual needs and are not limited here. The functions of the preset parts may include but are not limited to providing reference points, enabling the system to accurately obtain distance information based on the preset parts, etc.

[0053] In an optional embodiment, the distance information between a preset position of the target object and the plane of the current road on which the vehicle is traveling, i.e., a first preset plane, is determined based on the feature data. By measuring the distance between the target object and the road plane, the system can more accurately judge the relative position between the vehicle and pedestrians, obstacles, etc. This is crucial for the realization of functions such as automatic parking and blind spot monitoring, and can help the vehicle move flexibly in a small space, avoid scratches and other accidents, and enhance the comfort experience of passengers.

[0054] Step S106, adjusting the display parameters of the optical display screen based on the distance information and the current position information to obtain an adjustment result, wherein the optical display screen is displayed in an area of ​​the vehicle's windshield corresponding to a preset position of a preset seat.

[0055] The optomechanical display screen in the above steps is used to describe the screen in the augmented reality (AR) or head-up display (HUD) system. The optomechanical display screen can project information directly into the driver's field of vision. The types of optomechanical display screens may include but are not limited to laser projection, LED (Light Emitting Diode, LED) projection, micro display, etc. The specific optomechanical display screen needs to be determined according to actual needs and is not limited here.

[0057] The display parameters in the above steps are used to describe adjustable variables such as image quality, display position and display content that control the optical display screen. The display parameters may include but are not limited to virtual image height, inclination and projection angle. The specific display parameters need to be determined based on the actual situation inside the vehicle and are not limited here.

[0059] In an optional embodiment, by measuring the distance information between the preset part of the target object and the first preset plane, and determining the current position information of the preset seat, the system can adjust the virtual image height, inclination, contrast and other display parameters of the optical display screen to ensure that in any driving environment, the area of ​​the optical display screen corresponding to the preset position of the preset seat in the windshield of the vehicle can present a good visual effect. This adjustment process not only improves the clarity and readability of the information, reduces the visual fatigue of the driver, but also effectively avoids strong light reflection and interference, significantly enhancing driving safety.

[0060] In an optional embodiment, the display parameters of the optical display screen are adjusted according to the distance information h and the current position information w to obtain the adjustment result, which can be performed in the following manner:

[0061] First, when the vehicle is calibrated off the factory line, the adjustment parameters corresponding to the distance information h and the current position information w need to be calibrated, that is, a mapping table of the distance information h, the current position information w and the adjustment parameters is established. The mapping table reflects the correspondence between the distance information h and the current position information w and the adjustment parameters. Subsequently, the corresponding adjustment parameters can be quickly determined in the mapping table through the distance information h and the current position information w in the current state. The mapping table can be but is not limited to the adjustment parameter mapping table, as shown in Table 1 below:

[0062] Table 1

[0063]

[0064] As shown in the above table, the first row in the table represents multiple distance information such as h1 to hn, the first column represents multiple current position information such as w1 to wm, and the rest are adjustment parameters corresponding to different distance information and current position information.

[0065] After obtaining the distance information h and the current position information w, the corresponding adjustment parameters can be found according to the above table, and the gear adjustment can be performed according to the adjustment parameters. The gear adjustment formula is as follows:

[0066] ;

[0067] Wherein, w represents the current position information, h represents the distance information, x represents the current position information in the adjustment parameters, and y represents the distance information in the adjustment parameters.

[0068] In an embodiment of the present invention, first, in response to receiving a position adjustment instruction for a preset seat in a vehicle, the current position information of the preset seat is obtained, and the target object located on the preset seat is detected to obtain feature data of the target object; then, based on the feature data, the distance information between the preset part of the target object and the first preset plane is determined; finally, based on the distance information and the current position information, the display parameters of the optical display screen are adjusted to obtain an adjustment result. It is easy to notice that the present application obtains the current position information of the preset seat and the feature data of the target object through the position adjustment instruction, and then determines the distance information between the preset part of the target object and the plane where the vehicle is currently traveling based on the feature data, and finally adjusts the display parameters of the optical display screen through the obtained current position information and distance information, thereby achieving the purpose of adjusting the display parameters of the optical display screen, realizing the technical effect of intelligent and personalized adjustment of the display parameters of the optical display screen, and thus solving the technical problem of low adjustment efficiency of the vehicle optical display screen in the related technology.

[0069] Optionally, determining the distance information between a preset part of the target object and a first preset plane based on the feature data includes: determining the height information of the target object based on the feature data; determining initial distance information based on the product of the height information and a preset coefficient, wherein the preset coefficient is used to represent the correspondence between the preset part and a second preset plane, and the second preset plane is a plane where preset seats in the vehicle are located; determining distance information based on the initial distance information and the preset distance information, wherein the preset distance information is the distance information between the second preset plane and the first preset plane.

[0070] The above-mentioned height information is used to describe the height data of the target object.

[0071] The above-mentioned preset coefficients are parameters used to describe the corresponding relationship between the preset reaction preset part and the second preset plane. The types of preset coefficients may include but are not limited to the first coefficient and the second coefficient. The specific preset coefficients need to be determined based on the relationship between the preset part and the second preset plane. No limitation is made here. The role of the preset coefficients may include but is not limited to ensuring the rationality and accuracy of the calculation.

[0072] The above-mentioned initial distance information is used to describe the height information multiplied by a preset coefficient, and is used to represent the estimated distance between the preset part of the target object and the second preset plane. The initial distance information may include but is not limited to 0.5 meters, 0.6 meters and 0.7 meters, etc. The specific initial distance information needs to be determined based on the actual situation such as the height information, and is not limited here. The role of the initial distance information may include but is not limited to providing a starting point for subsequent precise calculations.

[0073] The above-mentioned second preset plane is used to describe the plane where the preset seats in the vehicle are located. The types of the second preset plane may include but are not limited to the driver's seat plane, the passenger seat plane and the vehicle floor plane. The specific second preset plane needs to be determined according to the target part and application scenario, and is not limited here. The function of the second preset plane may include but is not limited to providing a fixed reference point for the calculation of distance information.

[0074] The above-mentioned preset distance information is used to describe the known distance information between the second preset plane and the first preset plane. The specific preset distance information needs to be determined according to the settings of the second preset plane and the first preset plane, and is not limited here.

[0075] In an optional embodiment, the height of the target object is first determined by analyzing the characteristic data; then, the initial distance information between the preset part and the seat plane, i.e., the second preset plane, is calculated using the preset coefficient; finally, the system can accurately infer the distance information between the preset part and the first preset plane by combining the preset distance between the second preset plane and the plane where the vehicle is traveling, i.e., the first preset plane. In the above process, the initial distance between the preset part and the seat plane is estimated by multiplying the height information and the preset coefficient, and then corrected by the preset distance information between the seat plane and the traveling road plane, thereby achieving the goal of accurately obtaining the distance between a specific part and the key structure of the vehicle without directly contacting or measuring it. This method not only reduces the computational complexity, but also improves the real-time and reliability of the measurement, which is conducive to promoting the realization of functions such as automatic adjustment and safety warning of the vehicle system.

[0076] Optionally, the preset coefficients include a first coefficient and a second coefficient, and the initial distance information is determined based on the product of the height information and the preset coefficients, including: determining a first product of the height information and the first coefficient, and determining a second product of the height information and the second coefficient, wherein the first coefficient is used to represent the correspondence between a preset part of the target object when it is in a standing state and a second preset plane, and the second coefficient is used to represent the correspondence between a preset part of the target object when it is in a sitting state and the second preset plane; the initial distance information is determined based on the difference between the first product and the second product.

[0077] The first product mentioned above is used to describe the product of the height information and the first coefficient. The first product is used to represent the theoretical distance between the preset part of the target object and the second preset plane in a standing state.

[0078] The second product mentioned above is used to describe the product of the height information and the second coefficient. The second product is used to represent the theoretical distance between the preset part of the target object and the second preset plane in the sitting state.

[0079] In an optional embodiment, the product of the height and the coefficients in two different postures, namely, the standing posture and the sitting posture, is first calculated, and then the distance between the preset part of the target object and the reference plane in different postures, namely, the initial distance information, is determined by the difference between the products in the two different postures. The above method of determining the initial distance information based on the product of the height information and the preset coefficient effectively solves the problem of the decrease in accuracy of the traditional distance measurement technology when facing different postures. Among them, by accurately matching the height of the target object with the coefficient in a specific posture, the system can automatically and intelligently adapt to the real-time needs of the user, and can obtain the most suitable distance adjustment plan regardless of whether the user is standing or sitting.

[0080] In an optional embodiment, Figure 2 is a schematic diagram of a sitting posture of a target object on a preset seat according to an embodiment of the present invention, such as Figure 2 As shown, number 201 in the figure represents a camera, the lowest straight line represents the road plane on which the vehicle is traveling, the vehicle is located on the road, the target object is in a sitting driving state on a preset seat in the vehicle, the camera is located in front of the target object, and h in the figure represents the height of the pupil center of the target object's eye from the ground, h1 represents the distance between the center point of the eye of the target object when in a sitting position and the second preset plane, and h2 represents the distance between the second preset plane and the first preset plane.

[0081] Among them, the value of h2 has been determined when the vehicle leaves the factory and can be regarded as a known quantity. The estimation process of h1 is as follows: according to the proportions and sizes of various parts of the human body, the height of the eyes is approximately 0.9 times the height, and the length of the thigh is generally 0.341 times the height. The height of the target object is expressed in hr, then h1=0.9hr-0.341hr=0.559hr, and the height h of the driver's pupil center from the ground can be calculated based on h=h1+h2. The numerical estimation in the above process is only an example, and the specific value needs to be determined based on the actual height and proportion of the target object, which is not limited here.

[0082] Optionally, the target object located on the preset seat is detected to obtain characteristic data of the target object, including: identifying the target object located on the preset seat to obtain identification information of the target object; retrieving characteristic data corresponding to the identification information from a database of the vehicle based on the identification information, wherein the database is used to store characteristic data corresponding to different objects according to the identification information of different objects.

[0083] The above-mentioned identification information is used to describe information that can uniquely identify the target object. The identification information may include but is not limited to the passenger's facial features, fingerprints, irises and other information. The specific identification information needs to be determined based on different passengers and is not limited here. The role of the identification information may include but is not limited to identifying specific passengers, calling personalized configurations or services, etc.

[0084] The above-mentioned database is used to describe a warehouse for storing various characteristic data related to passengers. The database may include but is not limited to passenger driving preferences, biometric data, riding history, etc. The specific content of the database needs to be determined according to actual conditions and is not limited here. The type of database may include but is not limited to local databases, cloud databases, hybrid databases, etc. The specific database type needs to be determined according to actual needs and is not limited here. The role of the database may include but is not limited to storing and managing characteristic data related to passengers so that the vehicle system can quickly call up corresponding data based on the passenger's identification information, provide personalized services and enhance safety, etc.

[0085] In an optional embodiment, by identifying the target object's annotation information and retrieving the target object's characteristic data from the database based on the annotation information, the system can automatically identify the target object sitting on the preset seat. The above process can provide a more personalized driving or riding experience based on each user's habits and preferences, significantly enhancing the vehicle's intelligence level and user experience.
