Abstract:
Systems and methods for capturing and mosaicking images of one or more surfaces of a collapsed cavity are described. A number of embodiments are capable of performing mosaicking in real time. Many embodiments are configured to perform multiple passes during motion estimation and/or registration to improve the quality of the resulting mosaic(s). One embodiment includes capturing images using an endoscope, where the optics of the endoscope are radially symmetrical, locating the optical center of each of the captured images, dewarping each of the captured images by mapping the image from polar coordinates centered on the optical center of the image to rectangular coordinates, discarding portions of each dewarped image to create high clarity dewarped images, estimating the motion of the endoscope with respect to the interior surface of the cavity that occurred between successive high clarity dewarped images, registering the high clarity dewarped images with respect to each other using the estimates of motion, and combining the registered high clarity dewarped images to create at least one mosaic.
