Problems solved by technology

[0004] Different people have different sensitivities to light intensity in different environments, which makes the built-in algorithm adjustment function of HUD not suitable for everyone and scenes. Therefore, HUD must also support manual fine-tuning of display brightness to meet Different needs of users, however, the manual brightness adjustment model built in the traditional HUD is only for the fine-tuning of the current brightness level, lack of linkage mechanism, resulting in the final brightness change curve composed of each brightness level is incoherent, and no longer maintains a linear increase. characteristics, there are jumps, and at the same time, it may cause the brightness of the HUD display screen corresponding to the low illumination value to be higher than that of the HUD display screen at the high illumination value, resulting in abnormal visual results, making the user experience poor and affecting driving safety

Embodiment 1

[0078] Please refer to figure 1 , a method for optimizing the effect of HUD screen brightness adjustment, specifically, including steps:

[0079] S1. Receive an adjustment request for the brightness of the HUD display screen, where the adjustment request includes an adjusted brightness value;

[0080] For example, the user manually increases the brightness of the HUD display at an illumination value of 5000 from the original 456 to 502, and the terminal receives an adjustment request for the brightness of the HUD display, and the adjustment request includes the adjusted brightness value.

[0081] S2. Establish a second mathematical model according to the adjusted brightness value, its corresponding external illuminance value, and the first mathematical model established based on the external illuminance value and the original brightness value of the HUD display screen;

[0082] Specifically, the step S2 includes:

[0083]The first mathematical model includes model parameters...

Embodiment 2

[0132] Please refer to figure 2 , a terminal 1 that optimizes the effect of HUD screen brightness adjustment, the terminal 1 includes a memory 2, a processor 3, and a computer program stored in the memory 2 and operable on the processor 3, and the processor 3 executes The computer program realizes each step in the first embodiment.

[0133] In summary, the present invention provides a method and terminal for optimizing the effect of HUD screen brightness adjustment. For the user to manually adjust the brightness of the HUD display screen under the t illuminance value, the present invention uses the second mathematical model to adjust the corresponding brightness of the first mathematical model. Adjust the model parameters to ensure the smooth transition of the adjusted luminance value curve of the HUD display before and after the illuminance value t. Specifically, it is realized by synchronously adjusting the luminance values ​​of the HUD display corresponding to several illu...

Abstract

The invention discloses a method and terminal for optimizing the brightness adjustment effect of an HUD screen, and the method comprises the steps: receiving an adjustment request for the brightness of the HUD screen, and enabling the adjustment request to comprise an adjusted brightness value; establishing a second mathematical model according to the adjusted brightness value, the external illumination value corresponding to the adjusted brightness value and a first mathematical model established based on the external illumination value and the original brightness value of the HUD display screen; adjusting the first mathematical model according to the second mathematical model, so the brightness value curve of the HUD display screen after adjustment smoothly transitions before and after the adjusted brightness value, it is ensured that the brightness value curve of the optimized HUD display screen is coherent, and better visual experience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of head-up displays, in particular to a method and a terminal for optimizing the brightness adjustment effect of a HUD screen. Background technique [0002] Head Up Display (HUD), hereinafter referred to as HUD, is a driving assistance device used in automobiles, because it allows drivers to view important information of the car without lowering their heads and improves driving safety. In recent years, it has been widely installed in automobiles. [0003] Since HUD is a vehicle-mounted display device, its display brightness must always change with changes in the brightness data of the external environment, so that the content displayed on the HUD and the driver's field of vision can be merged and superimposed to ensure driving safety. When leaving the factory, there will be a built-in algorithm that automatically adjusts the brightness of its own display screen according to the external light intensity sensi...
