Abstract
A system and method for automatic image view alignment for road condition detection based on cameras on a transportation vehicle. The method includes converting a fisheye image to a distortion-free object image, comparing the object image to a reference image, aligning the object image to the reference image, and analyzing the aligned object image to detect and identify road conditions in real-time as the transportation vehicle is in operation. The object image is aligned to the reference image by performing a corrective transformation on the fisheye image by determining a distance (d) between predetermined feature points of the object image and the reference image, estimating a pitch angle Θ of a projection center based on the distance (d), and repositioning the projection center by the pitch angle Θ.
