Abstract

The invention relates to an AR-HUD image distortion correction method, device and system under a dynamic eye position, and belongs to the technical field of image processing, and the method comprisesthe steps: selecting a plurality of eye positions in an eye position adjustable space range; respectively establishing a mapping relationship from points on a projection virtual image plane to pointson an original input image plane; for a certain eye position in the EyeBox at the current moment, estimating the linear weight coefficient of the image by utilizing the relative relationship between the image and the selected eye position, and estimating the mapping relationship from each point on the virtual image surface to the midpoint of the original input image under the current eye positionby utilizing the same weight coefficient, so that the image in the image plane to be input is solved, and the effect of distortion correction is achieved. The AR-HUD virtual image distortion correction method and device solve the problem that HUD virtual image distortion seen by different eye positions of a driver is different, and AR-HUD virtual image distortion correction under the dynamic eye position is high in precision and high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a method, device and system for correcting AR-HUD image distortion under dynamic eye positions. Background technique [0002] According to statistical data, it takes about 4 to 7 seconds for the driver's sight to shift from the front of the vehicle to the dashboard, and to return to the front vision after obtaining the instrument information. During this period of time, the driver cannot obtain the environmental information ahead, and there is a huge potential safety hazard. Augmented reality head-up display (AR-HUD) uses augmented reality technology to reasonably superimpose and display information such as vehicle speed, navigation, driving assistance system status, and surrounding environmental conditions in the driver's field of vision, providing the driver with a more intuitive and realistic experience. Information, enhance the driver's environmental awareness, do not...
