Abstract
A corneal topography slit image alignment systemincludes a half-slit projectorfor projecting half-slit images onto a patient's eyeHalf-slit imagesandare aligned into a single slit image. A cameracaptures an image of the aligned slit image. Processorincluding a memoryconnected to the half-slit projectorand the cameraanalyzes the alignment of the half-slit imagesandAn edge detectordetects the edges of each captured half-slit image and determines an amount of misalignment of the half-slit imagesandrelative to half-slit images being aligned into a single slit image. This amount of misalignment allows computer processorto correct the three-dimensional coordinates of the slit images obtained by a slit beam system
