摘要:
传统玻璃后视镜风阻风噪大,无法接入智能驾驶系统,所以电子后视镜取代传统后视镜已成为趋势.但电子后视镜使用鱼眼摄像机,所显示图像畸变大,无法像玻璃后视镜一样在近距离放大驾驶员所关注的视野,远距离缩小物体以此显示更多视野.通过对玻璃视镜放大系数和驾驶员视野角和物距的分析,得出适用于电子后视镜图像放大系数变换的方法,根据此方法对电子后视镜图像进行处理,以此达到显示最佳观感.实验结果证明,变换后的电子后视镜图像各处放大系数与玻璃视镜相差为９．５２％,优于市面上仅经过鱼眼矫正的图像显示效果,在司机主观观感上能很好地提供“近距离放大外部环境,远距离更大视野”的功能,提高了驾驶安全性.
Abstract:
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 narrow 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 results 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.
