Efficient Method for Head-Up Display Image Compensation by Using Pre-Warping Method 2019-01-1008
A Head-Up Display (HUD) is electrical device that provide virtual images in front of driver. Virtual images are consists of various driving information. Because HUD use optical system there exist image distortion with respect to image height and driver’s eye position. Image warping is the image correction method that makes a geometrical change on image to minimize image distortion. To minimize image distortion, HUD use optical data driven warping matrix for each image height. But even we applied data driven warping matrix, image distortion occurs due to manufacturing tolerances at inline. In this paper, we suggest pre-warping method to minimize image distortion about each height steps on HUD. We simulated 3 cases to compensate the differences from the inline HUD image (reference height) for pre-warping matrix (every step). By using proposed pre-warping method we reduce total image x displacement by 30%, y displacement by 40%.
