The invention discloses a vehicle-mounted rearview mirror combining a physical mirror and an electronic mirror. A physical sight glass provided by the vehicle-mounted rearview mirror is of a five-piece type full-glass structure, free optical curved surface optimization design is adopted for the first two lighting lenses, and through matching of the specially-designed shapes, focal lengths, refractive indexes, abbe coefficients, curvature radiuses, center thicknesses and diaphragm positions of all the lenses and air intervals between all the lenses and diaphragms, the vehicle-mounted rearview mirror can be used for lighting the vehicle-mounted rearview mirror. The spatial size and the brightness information of the captured information need to have a relatively high reduction degree, so that the occurrence of image distortion and dark corners is reduced, and a relatively good imaging effect is formed. According to the invention, the possibility of dark corner and distortion when edge distant view light reaches a photosensitive device can be reduced, the problems of distant view imaging distortion, uneven brightness and large far and near imaging effect difference existing in the existing full spherical lens system are solved, and the lens design similar to a rearview mirror can be directly used for a modularized automobile vehicle-mounted electronic instrument, so that the system is convenient to use. And the integrated design of the vehicle-mounted auxiliary system and the locomotive is facilitated.

    本发明公开了一种物理镜与电子镜结合的车载后视镜。所述车载后视镜提供的物理视镜采用五片式全玻结构,前两片采光透镜采用自由光学曲面优化设计,通过特别设计的各透镜的形状、焦距、折射率、阿贝系数、曲率半径、中心厚度,光阑位置以及各透镜及光阑间的空气间隔的配合,对捕获的信息的空间尺寸和亮度信息需要有较高的还原度,减少了图像畸变与暗角的发生,形成较好的成像效果。本发明可以减少边缘远景光线到达感光器件上出现暗角、畸变的可能性,克服了现有全球面透镜系统存在的远景成像畸变以及亮度不均匀,远近成像效果差异大的问题,同时其类似后视镜的镜头设计可直接用于模块化汽车车载电子仪,有利于车载辅助系统与机车的一体化设计。
