博士 === 國立臺灣科技大學 === 機械工程系 === 100 === The present study proposes a novel mark-on-windshield warning system for vehicles, by which the driver can see the potential hazardous object in front by looking at the direction through the mark on the windshield, without the need of moving his sight to the equipped liquid crystal display (LCD) panel for identifying the position of the obstacle as in traditional arts. The target to be warmed after identified by the camera and software system will be used to construct the line-of-sight equation based on the coordinate system on 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-dimensional robotic 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 and an actual vehicle experimental platform are constructed to demonstrate the feasibility of the proposed system. Finally, the experiments with the warning system installed on a car driving on the road proved the effectiveness in real time.
