Abstract
A method for calibrating a vehicular vision system includes providing a camera at a vehicle, with the camera having a field of view. Images are captured with the camera and a set of resultant images are acquired for a classification. Information is extracted related to image features in the set of resultant images, and an appropriate subset of coefficients is determined. For each classification, a classification vector of at least one appropriate weight is stored that corresponds to the determined subset of coefficients.

A method for calibrating a vehicular vision system, said method comprising:
- providing a camera at a vehicle, said camera having a field of view;
- capturing images with said camera;
- acquiring a set of resultant images for a classification;
- extracting information related to image features in the set of resultant images;
- determining an appropriate subset of coefficients;
- and
- for each classification, storing a classification vector of at least one appropriate weight that corresponds to the determined subset of coefficients.
A method for calibrating a vehicular vision system, said method comprising:
- providing a camera at a vehicle, said camera having a field of view;
- capturing images with said camera;
- acquiring a set of resultant images for a classification;
- wherein the acquired resultant images comprise images of at least two regions of interest within the field of view of said camera;
- extracting information related to image features in the set of resultant images;
- determining an appropriate subset of coefficients;
- for each classification, storing a classification vector of at least one appropriate weight that corresponds to the determined subset of coefficients;
- and
- providing occlusion detection to detect an unacceptable occlusion at least partially occluding the field of view of said camera.
