Claim One:
1. A parking assist system of a vehicle, said parking assist system comprising: a camera configured to be disposed at a vehicle, wherein said camera, when disposed at the vehicle, has a field of view exterior of the vehicle; an image processor operable to process image data captured by said camera; wherein said image processor processes captured image data to detect parking space markers indicative of a parking space and to identify empty or available parking spaces; and wherein said image processor comprises a parking space detection algorithm that detects parking space markers by (i) extracting low level features from captured image data, (ii) classifying pixels as being part of a parking space line or not part of a parking space line, (iii) performing spatial line fitting to find lines in the captured images and to apply parking space geometry constraints, and (iv) detecting and selecting rectangles in the captured images.
