Popis: Most driver assistance systems require the driver to move his eyes away from the road to see real-time auxiliary warning information. The present study proposes a windshield warning system for vehicles that alerts the driver to potential hazardous objects in front via marks on the windshield. The target after being identified by a camera and software in an independent system is used to construct the line-of-sight equation based on the coordinate system of the moving vehicle. The explicit equation of the intersection point of the line of sight and the windshield surface is derived using the algebraic method. A warning mark is then projected at the intersection point on the windshield by a two-degree-of-freedom laser projector, allowing the driver to easily identify the obstacle. A computer simulation program of the system is developed to validate the mathematical model of the system. A virtual reality experimental platform is constructed to demonstrate the feasibility of the proposed system. Results show t...
