Abstract

The invention relates to an AR-HUD image distortion correction method, device and system under dynamic eye positions, belonging to the technical field of image processing, comprising the steps of: selecting several eye positions within a spatial range where the eye positions can be adjusted; The mapping relationship from the point on the image plane to the point on the original input image plane; for a certain eye position in the EyeBox at the current moment, use its relative relationship with the selected eye position to estimate its linear weight coefficient, and use this equivalent The weight coefficient of , estimates the mapping relationship from each point on the virtual image plane to the midpoint of the original input image under the current eye position, and thus obtains the image in the image plane that should be input, so as to achieve the effect of distortion correction. The invention solves the problem of different HUD virtual image distortion seen by the driver's eye position, and the AR-HUD virtual image distortion correction accuracy and accuracy are high under the dynamic eye position.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to an AR-HUD image distortion correction method, device and system under dynamic eye position. Background technique [0002] According to statistics, it takes about 4 to 7 seconds for the driver's sight to shift from the front of the vehicle to the instrument panel, and then to return to the front view after obtaining the instrument information. During this period, the driver cannot obtain the information of the environment ahead, and there is a huge potential safety hazard. Augmented reality head-up display (AR-HUD) uses augmented reality technology to reasonably superimpose information such as vehicle speed, navigation, driver assistance system status, and surrounding environment conditions in the driver's field of vision, providing drivers with more intuitive and realistic images. Information, enhances the driver's environmental perception ability, does not require or gre...
