Abstract:
1. A method of detecting a vehicle position by employing a polarization image, comprising: a polarization image obtaining step of capturing a polarization image by using a polarization camera; a road surface detecting step of acquiring two road shoulders in the polarization image based on a difference between a road surface in the polarization image and each of the two road shoulders in the polarization image, and determining a part between the two road shoulders as the road surface; a vehicle bottom detecting step of detecting at least one vehicle bottom from the road surface based on a pixel value difference between each wheel in the polarization image and the road surface in the polarization image; and a vehicle position generating step of generating a vehicle position from the vehicle bottom based on a pixel value difference between a vehicle outline corresponding to the vehicle bottom in the polarization image and background in the polarization image, wherein, the vehicle bottom detecting step includes,
