Embodiment 1

[0040] figure 2This is a schematic flowchart of a data processing method provided in Embodiment 1 of the present application. The method in this embodiment may be executed by the data processing apparatus provided in this embodiment of the present application, and the apparatus may be implemented by software and / or hardware, and can be integrated in figure 1 shown in the HUD. like figure 2 As shown, the data processing method of this embodiment includes:

[0041] S201. Receive image data sent by a host.

[0042] In this embodiment, the image data is the data of the screen to be displayed. In order to ensure the accuracy of the image screen displayed by the HUD, the image data sent by the ECU to the HUD includes both valid display data and verification data, wherein the valid display data is the to-be-displayed data. The data corresponding to the display screen actually seen by the user in the display screen, and the verification data is used to verify the data of the saf...

Embodiment 2

[0081] In the above embodiment 1, before sending the image data to the HUD, the host can also detect the image data first, and send corresponding control instructions to the HUD according to the specific content included in the image data to control the HUD to use the corresponding data. The processing flow processes the received image data. For a situation where the HUD is currently in a non-safety display mode, such as a normal display mode, correspondingly, before S201, the method of this embodiment may further include: receiving a mode switching instruction sent by the host for switching to the safe display mode, according to the The mode switching instruction switches to the safe display mode, and uses the steps in S201-S203 to process the image data.

[0082] The specific implementation of the mode switching will be described below with a specific embodiment. In this embodiment, according to different image data contents and different image data processing methods, the ...

Embodiment 3

[0099] On the basis of the above Embodiment 1 or Embodiment 2, the specific implementation of the data processing process will be described below with a specific embodiment. Exemplarily, Figure 7 A schematic diagram of a data packet format of verification data provided in Embodiment 3 of the present application, as shown in Figure 7 As shown, the first column is a set of m safety-related icons, the ID number of each safety-related icon in the set is the icon ID, and the second column to the m+1th column of the verification data is the order of each safety-related icon. characteristic data.

[0100] Illustratively, Figure 8 A schematic diagram of the data format of the feature data index provided in the third embodiment of the present application, such as Figure 8 As shown, the first column is the icon ID of the safety-related icon, the second column is the start coordinate of the safety-related icon (ie the icon position), and the third column is the number of features c...

Abstract

The embodiment of the invention provides a data processing method and device, a head-up display and a storage medium, and the method comprises the steps: receiving image data sent by a host end, the image data comprises effective display data and verification data, the image data is data of a to-be-displayed picture, and the to-be-displayed picture comprises a safety related icon; according to the verification data, verifying the target image data of the security related icon in the effective display data; and processing the image data according to the verification result. By setting the verification data to verify the data of the safety-related icons in the image data before controlling the display of the image data, the purpose of verifying the content of the image data is achieved on the premise of not increasing hardware cost, the display accuracy of the safety-related icons is ensured, and the driving safety of a user is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vehicles, and in particular, to a data processing method, device, head-up display, and storage medium. Background technique [0002] With the development of automotive electronic technology, safety functions have not only been applied to power-related electronic equipment, but also display-related equipment such as instruments and head up displays (HUDs) are gradually being required by OEMs to achieve functional safety. , the concept of safety display came into being. [0003] For HUD, safety display not only requires it to have anti-glare function, but also requires it to ensure the correctness of the displayed content as much as possible, so as to give the driver enough reminders and improve driving safety. This requires the HUD to verify the image data received from the host. In the prior art, the size of the received image data and the image data sent by the host end is d...
