System and method for automatic torsion correction in diagnostic ophthalmic measurements
Abstract:
The disclosure includes an automatic torsion correction system and method using a processor to access information regarding a first and a second infrared or white light image and a corresponding, concurrently captured first and second ophthalmic diagnostic image; identify ophthalmic features in the first infrared or white light image and the second infrared or white light image and use these features to determine a first torsion of the first infrared or white light image with respect to a vertical axis and a second torsion of the second infrared or white light image with respect to the vertical axis, then determine a first and a second torsion correction to align the first and second infrared or white light image with respect to the vertical axis and apply the first and second torsion corrections to the first and second ophthalmic diagnostic images, respectively, then send the corrected diagnostic images to a display.
