Abstract
A method of performing a camera to ground alignment for a camera system on a vehicle. The method includes determining if enabling conditions have occurred and estimating a location of a vanishing point in a source image. Ground lines are selected based on a source image. A lane line detection is performed based on clustering of the ground lines to determine lane lines in the source image. At least one of pitch, yaw, or roll of the vehicle are estimated from the source image. A cost function based on estimates of pitch, yaw, and roll is minimized to obtain an optimal pitch value, an optimal yaw value, an optimal roll value, and lane lines from the source image. A sliding window-based refinement is performed on source images. Alignment results are broadcast to a downstream application or it is determined if the camera system on the vehicle is misaligned.
