Abstract
Non-symmetric distortion generated by an imaging system producing a distortion predominantly in one image dimension is corrected by providing a distortion model capable of correcting the non-symmetric distortion in an image that is predominantly in the one image dimension, providing one or more correction parameters, wherein at least one correction parameter relates to the distortion predominantly in the one image dimension, and generating an image corrected for the non-symmetric distortion by using the distortion model and the one or more correction parameters.
Claims22
A method of correcting for non-symmetric distortion in an image generated from an imaging system producing a distortion predominantly in one image dimension, said method comprising the steps of:
- a) providing a distortion model capable of correcting the non-symmetric distortion in the image that is predominantly in the one image dimension;
- b) providing one or more correction parameters, wherein at least one correction parameter relates to the distortion predominantly in the one image dimension;
- and
- c) generating an image corrected for the non-symmetric distortion by using the distortion model and the one or more correction parameters.
A method of capturing an image and correcting for non-symmetric distortion in the image, said method comprising the steps of:
- a) generating an image from an image capture surface producing a non-symmetric distortion predominantly in a particular image dimension due to curvature of the image capture surface;
- b) providing a distortion model capable of correcting the non-symmetric distortion in the image that is predominantly in the particular image dimension;
- c) providing one or more correction parameters, wherein at least one correction parameter relates to the distortion predominantly in the particular image dimension;
- and
- d) generating an image corrected for the non-symmetric distortion by using the distortion model and the one or more correction parameters.
A system for correcting non-symmetric distortion in an image generated from an imaging system producing a distortion predominantly in one image dimension, said system comprising:
- a) a distortion corrector utilizing a distortion model capable of correcting the non-symmetric distortion in the image that is predominantly in the one image dimension;
- b) a source of one or more correction parameters, wherein at least one correction parameter relates to the distortion predominantly in the one image dimension;
- and
- c) means for inputting the correction parameters into the distortion corrector, thereby generating an image corrected for distortion by using the distortion model and the correction parameters.
A system of capturing an image and correcting for non-symmetric distortion in the image, said system comprising:
- an image capture device for generating an image from an image capture surface producing a non-symmetric distortion predominantly in a particular image dimension due to curvature of the image capture surface;
- a distortion corrector utilizing a distortion model capable of correcting the non-symmetric distortion in the image that is predominantly in the particular image dimension;
- a source of one or more correction parameters, wherein at least one correction parameter relates to the distortion predominantly in the particular image dimension;
- and
- means for inputting the correction factors into the distortion corrector, thereby generating an image corrected for the non-symmetric distortion by using the distortion model and the one or more correction parameters.
