Abstract

The invention discloses a vehicle-mounted AR-HUD brightness adaptive adjustment anti-shake method, belongs to the technical field of vehicle-mounted AR-HUD brightness adjustment methods, and solves the technical problem of low comfort of product observation in the prior art. The method comprises the following steps of: determining an optimal anti-jitter threshold period TO according to factors influencing brightness adjustment jitter and a jitter period measured by field experiments of vehicles of different models; determining a brightness value of each time point of the threshold period TO; performing weighted averaging on the brightness values of all the time points to determine an average brightness value; taking the average brightness value as a first display value of the vehicle-mounted AR-HUD brightness in the next period, and acquiring a first acquisition value of the vehicle-mounted AR-HUD brightness in the current period; performing filtering processing on the first acquisition value to determine a brightness value after fluctuation filtering; taking the brightness value after the fluctuation is filtered as a second display value of the brightness of the next period, and acquiring a second acquisition value of the vehicle-mounted AR-HUD brightness in the current period; and carrying out circulation in a preset number of periods in sequence to improve the comfort level.

Description

technical field [0001] The invention belongs to the technical field of a vehicle-mounted AR-HUD brightness adjustment method, and in particular relates to an anti-shake method for adaptively adjusting the brightness of a vehicle-mounted AR-HUD. Background technique [0002] Augmented Reality Head Up Display (ARHUD) is a driving assistance device currently used in passenger cars. Prompt information such as vehicle speed, rotation speed, navigation, and fault warnings can be displayed within the driver's front-of-sight range, reducing the frequency of the driver looking down at the instrument to improve driving safety and improve the driver's perception of the surrounding environment. [0003] Since the AR-HUD display brightness directly affects the comfort and accuracy of the driver's observation of road conditions, it is necessary to precisely control the display brightness. The traditional AR-HUD brightness adaptive adjustment is too sensitive. When passing by the shade of...
