Heads-up display processing methods, equipment, vehicles and storage media
By dividing the display area of the HUD display device into ground-mounted and non-ground-mounted areas, and using different distortion correction methods, and calibrating using oblique projection and orthographic projection standard diagrams, the problem of image distortion in HUD projection display being unable to adapt to the deviation of each vehicle is solved, achieving precise image correction and a simplified correction process.

AI Technical Summary
In existing technologies, HUD projection display image distortion correction cannot adapt to the actual deviation of each vehicle, resulting in ineffective handling of image distortion, especially in complex issues with both ground-facing and non-ground-facing displays.
The display area of the HUD display device is divided into a ground-level oblique projection area and a non-ground-level orthographic projection area. Different distortion correction methods are used to accurately correct the production and installation deviations of each vehicle. The corresponding distortion parameters are obtained by calibrating the oblique projection standard map and the orthographic projection standard map for image correction.
It achieves precise distortion correction for HUD projection displays, improves the effect of multi-projection displays, simplifies the correction process, and reduces hardware costs.
