Abstract
Video overlay synchronization for a digital surgical stereoscope is disclosed herein. In an example, a system provides synchronization by detecting how an image changes between frames. The image change corresponds to detecting the regular and predictable movement of human tissue, such as pulsing of a blood vessel. Peaks or maximum extents of tissue movement is tracked overtime to determine an estimation of the regular periodic movement. This periodic movement is used to align a short recording of images corresponding to a fluorescence imaging mode with a live or near-live recording of images in a visible light mode. The frame rate of fluorescence image data is adjusted to ensure close or almost exact alignment of tissue position shown in both the fluorescence image data and visible light image data. The system accordingly provides a fluorescence image overlay on visible light images for tissue that has regular movement patterns.
