Abstract

The invention belongs to the field of HUD technology, in particular to a method and a system for automatically adjusting the display color of a vehicle-mounted HUD based on ambient light color and aims to solve the problem that in the prior art, the display color of an HUD cannot adapt to external environment color changes. The method comprises the steps that an image of an environment ahead of a traveling vehicle is acquired; the acquired image is processed, and a dominant hue in the image is calculated; and the display color of content of the vehicle-mounted HUD is changed according to the dominant hue of the image. According to the method, the image of the environment ahead of the traveling vehicle can be collected through a camera, the acquired image is processed, the dominant hue in the image is calculated, then the content color of the HUD is adjusted according to changes of the dominant hue, and therefore a driver can clearly recognize the content of the HUD no matter what kind of driving environment the driver is located.

Description

technical field [0001] The invention belongs to the technical field of HUD, and in particular relates to a method and a system for automatically adjusting the display color of a vehicle-mounted HUD based on the color of ambient light. Background technique [0002] HUD is the abbreviation of Head Up Display in English, which means "head up display", also known as head-up display system. HUD first appeared on military aircraft, projecting flight-related advice onto the front glass. The purpose is to prevent the pilot from looking down at the display and data of the instrument, and always keep his head up, thereby improving driving safety. With the development of electronic information technology, HUD technology is gradually applied to civilian vehicles. [0003] At present, the color of the vehicle HUD is often unchanged during use. With the change of the color in the driving environment, when the color of the content displayed on the HUD is similar to the color of the drivin...
