Embodiment

[0023] Such as figure 1 As shown, in this embodiment, the design method of the AR-HUD head-up display interface that enhances the driving experience includes the following steps:

[0024] S1. Collect image information of the driving environment through a camera.

[0025] The camera is installed in the middle of the front windshield of the vehicle, and the optical axis of the camera is parallel to the longitudinal central axis of the vehicle, and the camera and the ground form a 0-5 degree overlooking angle.

[0026] S2. Adjust the internal parameter matrix, distortion coefficient and external parameter matrix of the camera to complete camera calibration.

[0027] What this embodiment adopts is the calibration method of two-dimensional plane graphics, using the monocular camera calibration in Matlab, the calibration process is as follows: print a checkerboard pattern, and spread this checkerboard grid on a plane, and measure it at the same time The width of the checkerboard; ...

Abstract

The invention relates to a design method of an AR-HUD interface for enhancing driving feeling, which belongs to the field of virtual reality and comprises the following steps: acquiring image information of a driving environment through a camera; finishing camera parameters are adjusted, and camera calibration; preprocessing the image; performing virtual imaging, calibrating parameters related to the AR-HUD system, so that virtual and real registration of an object is realized, and matching, alignment and prompting of a navigation virtual mark and a road real target are realized; designing an AR-HUD interface, building a virtual driving scene in a game engine, connecting entity vehicle equipment through a related port, then building a virtual test platform in combination with a head-mounted VR display system, and selecting an optimal AR-HUD display system. According to the invention, the defects of long real vehicle test period, high cost, high risk and the like are effectively avoided, and meanwhile, the defects in the aspects of interface design architecture, visual matching of a user and the like in the prior art are overcome.

Description

technical field [0001] The present invention relates to the field of driving display technology, in particular to a design method for an AR (Augmented Reality, Augmented Reality)-HUD (Head Up Display, head-up display) interface that enhances driving experience. Background technique [0002] With the improvement of people's living standards, the number of motor vehicles has increased sharply; at the same time, with the development of computer technology and graphics processing technology, the improvement of hardware performance, virtual driving and automatic driving technologies have become increasingly mature, and in recent years there have been vehicles that can enhance the driving experience. AR-HUD head-up display technology, the front window augmented reality head-up display has appeared. [0003] The existing AR-HUD head-up display technology does not have a perfect and unified interface design scheme, which is not conducive to the research and development of the car he...
