A method and apparatus for providing a distortion corrected video signal. A camera is directed toward a test pattern for producing a raw video signal. An image processor is operatively connected to the camera for receiving the raw video signal. The image processor is operable to capture at least one calibration image of the test pattern using the raw video signal from the camera, analyze the at least one calibration image to provide a calibration data table, and store the calibration data table within the image processor.

Automatic calibration for camera lens distortion correction

A method for identifying objects in an electronic image is provided. The method includes the steps of providing an electronic source image and processing the electronic source image to identify edge pixels. The method further includes the steps of providing an electronic representation of the edge pixels and processing the electronic representation of the edge pixels to identify valid edge center pixels. The method still further includes the step of proving an electronic representation of the valid edge center pixels. Each valid edge center pixel represents the approximate center of a horizontal edge segment of a target width. The horizontal edge segment is made up of essentially contiguous edge pixels. The method also includes the steps of determining symmetry values of test regions associated with valid edge center pixels, and classifying the test regions based on factors including symmetry.
