Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.
[0046] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0047] Specifically, Figure 1 This is a flowchart illustrating a method for verifying the display effect of a HUD, as provided in an embodiment of this application.
[0048] like Figure 1 As shown, the method for verifying the HUD display effect includes the following steps:
[0049] In step S101, vehicle data related to the head-up display (HUD) system is acquired.
[0050] The vehicle data includes one or more of the following: dashboard data, windshield data, HUD data, ground line data, and human hard point data; the vehicle data to be acquired can be as follows: Figure 2 As shown.
[0051] It is understandable that, such as Figure 3 As shown, the embodiments of this application can first collect vehicle data related to the vehicle HUD, thereby facilitating the establishment of the simulation environment using vehicle data in subsequent steps; wherein, the embodiments of this application can use at least one method to obtain vehicle data related to the head-up display system HUD, such as using CATIA software tools to obtain and collect material optical properties, etc., without specific limitations.
[0052] In step S102, a simulation environment for verifying the HUD display effect is established based on the vehicle data, and the HUD is simulated in the simulation environment to obtain the simulation results.
[0053] It is understood that, in this embodiment of the application, after obtaining relevant data in step S101, a simulation environment for verifying the HUD display effect can be established based on the vehicle data. After the simulation model is built, HUD imaging simulation is further performed in the simulation environment to obtain simulation results. In this embodiment of the application, the relevant data obtained can also be processed before establishing the simulation environment to improve the accuracy and reliability of the simulation environment establishment. The simulation analysis software used in this embodiment of the application can be set according to the actual situation, such as using SPEOS simulation analysis software, etc., without specific limitations.
[0054] In this embodiment of the application, a simulation environment for verifying the HUD display effect is established based on vehicle data, including: establishing a three-dimensional human body model of the driver based on human hard point data; simulating the actual driving environment based on instrument panel data, windshield data, HUD data and ground line data, and simulating the driver's eye position on the windshield.
[0055] Among them, such as Figure 4 As shown, the driver's eye point on the windshield can be the center point of the eye ellipse, as well as the upper, lower, left, and right poles.
[0056] It is understood that, in this embodiment of the application, a three-dimensional human body model of the driver can be established based on the human body hard point data obtained in step S101 above, thereby confirming the driver's eye position and further simulating the driver's eye position on the windshield; at the same time, this embodiment of the application can also simulate the current driving environment based on instrument panel data, windshield data, HUD data and ground line data.
[0057] In this embodiment of the application, the actual driving environment is simulated based on dashboard data, windshield data, HUD data, and ground line data, including: simulating the in-vehicle environment based on dashboard data, windshield data, and HUD data; and simulating the out-of-vehicle environment based on ground line data.
[0058] It is understood that the actual driving environment in this application embodiment can include the actual in-vehicle environment and the actual out-of-vehicle environment. Therefore, this application embodiment can simulate the in-vehicle environment using dashboard data, windshield data, and HUD data, and simulate the out-of-vehicle environment using ground line data. The specific process of simulating the in-vehicle and out-of-vehicle environments in this application embodiment can be as follows:
[0059] (1) In-vehicle environment simulation
[0060] In this embodiment of the application, the in-vehicle environment is simulated based on dashboard data, windshield data, and HUD data, including: extracting the material and optical properties of the materials in the dashboard data, windshield data, and HUD data; integrating materials of the same material to obtain an overall surface; and assigning optical properties to the overall surface based on the optical properties of the materials.
[0061] It is understood that, in the embodiments of this application, after extracting the material and optical properties of materials in the dashboard data, windshield data and HUD data, materials of the same material can be simplified, stitched into a whole surface, and the stitched surface can be given optical properties of the material based on the collected optical properties of the material; wherein, the embodiments of this application can also establish a material library containing optical properties.
[0062] (2) Simulation of the external environment
[0063] In this embodiment of the application, simulating the external environment of the vehicle based on ground line data includes: acquiring environmental parameters; and simulating the external environment of the vehicle based on the environmental parameters and ground line data.
[0064] In this application, environmental parameters can be obtained in at least one way, and no specific limitation is made thereto.
[0065] It is understood that, in the embodiments of this application, after acquiring the environmental parameters around the vehicle body, the external environment of the vehicle can be simulated based on the environmental parameters and ground line data.
[0066] In step S103, the display effect of the HUD is determined based on the simulation results and preset standards.
[0067] The preset standards can be set according to actual conditions, and no specific limitations are imposed on them; the correct display position of the HUD can be as follows: Figure 5 The windshield is shown in section A, number 11.
[0068] It is understood that, in the embodiments of this application, after the simulation model is built, the HUD imaging can be simulated. After obtaining the simulation results, the acceptability of the simulation results can be judged by comparing the results obtained from the simulation analysis with the preset standards, and the display effect of the HUD can be selected and confirmed.
[0069] In this embodiment of the application, after determining the display effect of the HUD based on the simulation results and preset standards, the method further includes: adjusting the relevant parameters of the HUD based on the display effect.
[0070] It is understandable that after determining the display effect of the HUD, if the imaging position and effect are unacceptable, the embodiments of this application can also adjust the relevant HUD parameters. For example, the position, angle and glass angle of the HUD in the original vehicle data can be adjusted according to the HUD imaging position, and then analysis can be performed according to the parameter standards, thereby eliminating risks and meeting the actual use needs.
[0071] The method for verifying the HUD display effect of this application will be described below with reference to a specific embodiment, as follows:
[0072] Step 1: Extract the raw data of a passenger vehicle, and simplify, stitch together, and assign optical properties to the raw data;
[0073] Step two: Establish a material library containing optical properties in the software system, assign material optical properties to the extracted surfaces, and use the SPEOS software tool to establish a simulation of the actual driving environment on the computer; wherein, in this embodiment of the application, you can choose to experimentally verify a representative scenario that is more in line with the actual driving environment, such as daytime sunny road conditions, so as to make the simulation results more representative.
[0074] Step 3: Establish simulated driver's eye points on the computer, and select eye points that, through experimental verification, can accurately represent the actual state observed from the driver's perspective. The simulated eye point diagram can be shown as follows: Figure 4 As shown;
[0075] Step four: After the simulation model is built, based on the optical analysis using the SPEOS software tool, a complete HUD imaging display simulation diagram is obtained. The imaging simulation diagram can be shown as follows: Figure 6 As shown; wherein, in this embodiment of the application, the image and the imaging position standard can be compared and analyzed to determine whether they meet the comparison parameter requirements;
[0076] When the imaging position is accurate, it can be considered to meet the requirements of the result comparison parameters, that is, the HUD imaging position of this model meets the design requirements in the theoretical verification stage; when the imaging position is not good, the HUD position and angle, the curvature, relative position and angle of the internal optical lens of the HUD, and the tilt angle and curvature of the windshield in the original data can be adjusted according to the imaging position. After the adjustment is made, the analysis is carried out again according to the imaging position parameter standard to finally eliminate the risk.
[0077] For example, when the imaging location is located as Figure 5 When the image is within area A of the windshield as shown, it can be considered to meet the requirements of the result comparison parameters, that is, the HUD imaging position of this model meets the design requirements in the theoretical verification stage; when the imaging position is outside area A, it is considered not to meet the requirements of the comparison parameters.
[0078] In summary, the method for verifying the HUD display effect proposed in the embodiments of this application has at least the following advantages:
[0079] (1) The embodiments of this application can use HUD-related vehicle data to establish a simulation environment, and confirm the final HUD display effect by comparing the simulation imaging with the preset standard.

Moreover, since the simulation results are compared with the preset standard to confirm the final HUD display effect, a clear risk assessment standard and an intuitive HUD imaging position verification method can be provided, thereby improving the accuracy and reliability of HUD imaging position verification and meeting the needs of actual use.
[0080] (2) The embodiments of this application can use human hard point data to build a three-dimensional human body model of the driver, and use instrument panel data, windshield data, HUD data and ground line data to simulate the actual driving environment, thereby simulating the driver's eye point at the windshield; because the vehicle model data and the driver data of this vehicle are used, the modeling accuracy can be improved, it is more suitable for the scene, and the results are more reliable.
[0081] (3) The embodiments of this application can use relevant data to simulate the in-vehicle and out-of-vehicle environments separately when simulating the driving environment, so that the driving environment simulation is more comprehensive, the simulation results are more reliable, and the actual needs are met.
[0082] (4) The embodiments of this application can simplify the stitching of materials of the same material to obtain an integral surface and give it optical properties to meet the imaging needs of complex multi-curved surface components such as HUDs;
[0083] (5) The embodiments of this application can further obtain environmental data around the vehicle, simulate the external environment of the vehicle based on environmental parameters and ground line data, improve the adaptability of the simulated environment to the vehicle environment, and meet the actual use needs;
[0084] (6) The embodiments of this application can identify and judge the risks of HUD display location during the design stage, thereby improving the efficiency of HUD display location risk judgment, reducing verification cycle, reducing costs, and meeting actual use needs.
