[0002] As cars are equipped with more and more functions, the content displayed on the car's instrument panel is becoming increasingly rich and diverse. Among them, icons, including vehicle indicator lights, warning lights, and other icon information, serve to guide the driver. Therefore, verifying the accuracy of the car's instrument panel icons can ensure that the driver receives the correct icon information.

[0008] Based on the instrument display position of the texture icon, a verification icon corresponding to the instrument display position is obtained from a preset icon library;

[0009] Based on the texture icon and the verification icon, the texture icon is verified according to a preset verification strategy to obtain the icon verification result;

[0010] When the icon verification result meets the preset verification requirements, the ION memory is sent to the direct rendering manager through the ION memory manager, so that the direct rendering manager can display the icon to be displayed on the display interface of the car instrument panel according to the ION memory.

[0011] As a preferred embodiment, the background of the texture icon is non-transparent, and the background of the verification icon is transparent.

[0012] Then, the step of verifying the texture icon according to a preset verification strategy based on the texture icon and the verification icon to obtain the icon verification result specifically includes the following steps:

[0013] Based on the verification icon, the non-transparent background of the texture icon is removed to obtain the texture icon after background removal;

[0014] The texture icon after removing the background is compared with the verification icon to obtain the icon verification result.

[0015] As a preferred embodiment, the step of removing the non-transparent background of the texture icon based on the verification icon to obtain the texture icon after background removal specifically includes the following steps:

[0016] Perform a bitwise AND operation between the texture icon and the verification icon to remove the non-transparent background of the texture icon, thereby obtaining the texture icon after removing the background;

[0017] The rgba value of the transparent background of the verification icon is 0x00000000.

[0018] As a preferred embodiment, comparing the textured icon (after removing the background) with the verification icon to obtain the icon verification result specifically includes the following steps:

[0019] Perform an XOR operation between the texture icon (after removing the background) and the verification icon to obtain the XOR result, and use the XOR result as the icon verification result.

[0020] As a preferred embodiment, when the icon verification result meets the preset verification requirements, the ION memory is sent to the direct rendering manager through the ION memory manager, specifically including the following steps:

[0021] When the XOR operation result is 0, the ION memory is sent to the direct rendering manager through the ION memory manager.

[0022] As a preferred embodiment, setting the ION memory to the texture icon corresponding to the icon to be displayed specifically includes the following steps:

[0023] The ION memory is set to the texture icon corresponding to the icon to be displayed using the glBindTexture and glEGLImageTargetTexture2DOES functions.

[0024] As a preferred embodiment, the method further includes the following steps:

[0025] When the icon verification result does not meet the preset verification requirements, an error message is generated and sent to the instrument interface management device configured with the instrument interface management application.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] See Figure 1 The first aspect of this invention provides a method for verifying automotive instrument panel icons, comprising the following steps S1 to S5:

[0041] Step S1: When the icon display process is detected to be starting, the libdrm library call process of the direct rendering manager of the car instrument panel is truncated.

[0042] Step S2: Obtain the ION memory corresponding to the icon to be displayed from the ION memory manager, and set the ION memory as the texture icon corresponding to the icon to be displayed;

[0043] Step S3: Based on the instrument display position of the texture icon, obtain the verification icon corresponding to the instrument display position from the preset icon library;

[0044] Step S4: Based on the texture icon and the verification icon, verify the texture icon according to a preset verification strategy to obtain the icon verification result;

[0045] Step S5: When the icon verification result meets the preset verification requirements, the ION memory is sent to the direct rendering manager through the ION memory manager, so that the texture icon is displayed on the display interface of the car instrument panel through the direct rendering manager according to the ION memory.

[0046] It's worth noting that in existing Linux or QuX automotive instrument clusters, the instrument cluster application typically uses the QT or Kanzi graphics library to draw the icons to be displayed. Then, OpenGL or Vulkan is used to synthesize the instrument cluster interface based on these icons, and the results are sent to the ION memory manager. Finally, the ION memory manager sends the ION memory corresponding to the icon to the direct rendering manager, which then displays the icon in the automotive instrument cluster based on this ION memory. Therefore, the icon display process does not validate the drawn icons. This necessitates using an additional in-vehicle video verification device to capture the automotive instrument cluster interface at the time of icon display and to validate the icons. However, this method only verifies the icon as erroneous when an incorrect icon is displayed; it cannot validate the icon before an incorrect icon is displayed.

[0047] Based on this, this embodiment truncates the libdrm library call process of the vehicle's instrument cluster's direct rendering manager when the icon display process is detected to have started. It's worth noting that the libdrm library is a standard library required by the direct rendering manager for icon display. Therefore, trunculating the libdrm library call process avoids OpenGL or Vulkan from composing the instrument cluster interface based on the icon to be displayed and sending it to the ION memory manager. Instead, the ION memory manager directly sends the ION memory corresponding to the icon to be displayed to the direct rendering manager for display.

[0048] Furthermore, the ION memory corresponding to the icon to be displayed is obtained from the ION memory manager, and this ION memory is set as the texture icon corresponding to the icon to be displayed. Since this embodiment needs to verify the accuracy of the icon to be displayed, it is necessary to first set the ION memory to the corresponding texture icon, and then verify the texture of the icon to be displayed.

[0049] Furthermore, based on the instrument display position of the texture icon, a verification icon corresponding to the instrument display position is obtained from a preset icon library. It is worth noting that this embodiment pre-saves correct verification icons to form an icon library. Each verification icon has configuration parameters, including pixel value, icon size, and instrument display position. For example, a turn signal icon is a 32×32 icon located at position (300, 400) on the instrument interface. Therefore, in the icon library, the configuration parameters of the verification icon corresponding to this icon include pixel value, x-axis coordinate of 300, y-axis coordinate of 400, width of 32, and height of 32.

[0050] Furthermore, based on the texture icon and the verification icon, the texture icon is verified according to a preset verification strategy to obtain the icon verification result. It is understandable that since the texture of the verification icon is completely correct, it can be used to verify the texture icon to be displayed.

[0051] Furthermore, when the icon verification result meets the preset verification requirements, it indicates that the texture of the icon to be displayed is accurate. Therefore, the ION memory is sent to the direct rendering manager through the ION memory manager, so that the direct rendering manager can display the icon to be displayed on the display interface of the car instrument panel based on the ION memory.

[0052] This invention provides a method for verifying automotive instrument panel icons. By directly setting the ION memory corresponding to the icon to be displayed as a texture icon and using a verification icon from a preset icon library to verify the texture icon, the method can verify the icon to be displayed in real time and accurately without the need for additional video verification equipment.

[0053] As a preferred embodiment, the background of the texture icon is non-transparent, and the background of the verification icon is transparent.

[0054] Then, the step of verifying the texture icon according to a preset verification strategy based on the texture icon and the verification icon to obtain the icon verification result specifically includes the following steps:

[0055] Based on the verification icon, the non-transparent background of the texture icon is removed to obtain the texture icon after background removal;

[0056] The texture icon after removing the background is compared with the verification icon to obtain the icon verification result.

[0057] It is worth noting that the icons rendered through the instrumentation interface application have a background, such as... Figure 2 As shown, Figure 2The dotted line in the image represents the non-transparent background of the texture icon. In contrast, the validation icons in the icon library, except for the icon texture which is the valid area, have transparent areas elsewhere, such as... Figure 3 As shown, Figure 3 The blank space in the image is the transparent background of the verification icon.

[0058] Based on this, this embodiment can remove the non-transparent background of the texture icon according to the transparent background of the verification icon, so as to retain only the texture part in the texture icon and obtain the texture icon after removing the background.

[0059] Furthermore, the textured icon after removing the background is compared with the verification icon to determine whether their textures are consistent, thereby obtaining the icon verification result.

[0060] As a preferred embodiment, the step of removing the non-transparent background of the texture icon based on the verification icon to obtain the texture icon after background removal specifically includes the following steps:

[0061] Perform a bitwise AND operation between the texture icon and the verification icon to remove the non-transparent background of the texture icon, thereby obtaining the texture icon after removing the background;

[0062] The rgba value of the transparent background of the verification icon is 0x00000000.

[0063] Specifically, since the rgba value of the transparent background of the verification icon is 0x00000000, performing a bitwise AND operation between the texture icon and the verification icon can remove the non-transparent background of the texture icon.

[0064] As a preferred embodiment, comparing the textured icon (after removing the background) with the verification icon to obtain the icon verification result specifically includes the following steps:

[0065] Perform an XOR operation between the texture icon (after removing the background) and the verification icon to obtain the XOR result, and use the XOR result as the icon verification result.

[0066] It is worth noting that the texture icon after removing the background is XORed with the verification icon. If the textures of the two are exactly the same, the result of the XOR operation is 0; otherwise, the result of the XOR operation is 1.

[0067] As another optional embodiment, the texture icon after removing the background is XORed with the verification icon. If the textures of the two are exactly the same, the result of the XOR operation is 1; otherwise, the result of the XOR operation is 0.

[0068] As a preferred embodiment, when the icon verification result meets the preset verification requirements, the ION memory is sent to the direct rendering manager through the ION memory manager, specifically including the following steps:

[0069] When the XOR operation result is 0, the ION memory is sent to the direct rendering manager through the ION memory manager.

[0070] As a preferred embodiment, setting the ION memory to the texture icon corresponding to the icon to be displayed specifically includes the following steps:

[0071] The ION memory is set to the texture icon corresponding to the icon to be displayed using the glBindTexture and glEGLImageTargetTexture2DOES functions.

[0072] It is worth noting that the glBindTexture and glEGLImageTargetTexture2DOES functions are both standard OpenGL functions used to set ION memory as an OpenGL texture.

[0073] As a preferred embodiment, the method further includes the following steps:

[0074] When the icon verification result does not meet the preset verification requirements, an error message is generated and sent to the instrument interface management device configured with the instrument interface management application.

[0075] It is worth noting that when the icon verification result does not meet the preset verification requirements, the texture of the icon to be displayed is incorrect. Therefore, this embodiment does not send the ION memory corresponding to the icon to be displayed to the direct rendering manager through the ION memory manager. Instead, it generates an error message and sends the error message to the instrument interface management device configured with the instrument interface management application. This allows the instrument interface management application to handle the icon error based on the error message, effectively preventing the display of incorrect icons in the instrument interface.

[0088] The rgba value of the transparent background of the verification icon is 0x00000000.
