Research and Application of Electronic Rearview Mirror Image Method Based on Optimal Visual Effect
Because the traditional glass rearview mirror has high wind resistance and noise,it cannot be connected to the intelligent driving system.Therefore,electronic rearview mirror has become a trend to replace the traditional rearview mirror.However,the electronic rearview mirror uses a fisheye camera,which shows large image distortion.It cannot enlarge the driver's attention field in close distance and nar-row the object in long distance to display more field of vision like the glass rearview mirror.Therefore,in this paper,the fisheye distorted image is corrected first,and then the electronic rearview mirror image is transformed by analyzing the magnification coefficient of the glass mirror and the driver's field Angle,so as to achieve the best view and feeling of the electronic rearview mirror image display.Experimental re-sults show that the display effect of the electronic rearview mirror system can well provide the function of enlarging the external environment at close distance and providing a wider field of vision at long distance,which improves driving safety.
