Abstract
A rear view assembly includes a housing, which is fixedly secured to a motor vehicle. The housing includes an optical sensor that is housed therewith. A lens focuses light for the optical sensor to capture a wide-angle image. The optical sensor creates electrical signals representative of the focused light. The electrical signals are transmitted to a display device, which is operatively connected to the optical sensor for receiving the electrical signal and displaying the electrical signal as a rear view image for a driver of the motor vehicle such that the rear view image includes distortions created by the lens.
Claims13
A rear view assembly for a motor vehicle, said rear view assembly comprising:
- a housing fixedly secured to the motor vehicle, said housing including an optical sensor housed therewith and a lens focusing light for said optical sensor to capture a wide-angle image, said optical sensor creating electrical signal representative of the focused light;
- a display device operatively connected to said optical sensor for receiving said electrical signal and for displaying the electrical signal as a rear view image for a driver of the motor vehicle such that said rear view image includes distortions created by said lens.
A method for exterior mirror simulation, whereby an image of a wide-angle lens having a field of view is recorded, and the information of the pixels of the optical sensor undergoes the following steps:
- recording of the image;
- determining the distortion;
- selecting an image rectification algorithm;
- applying the rectification algorithm to subset of the total pixels in the image to create a rectified image;
- storing the rectified image;
- and
- displaying the rectified image on the display.
