ABSTRACT:
In connection with imaging an inner surface of a body lumen, a mosaiced image is created from discrete images or a video produced with a small camera, as the camera is moved through the lumen. In one embodiment, a tethered capsule with a scanning optical fiber provides the images, although other types of endoscopic cameras can instead be used. A surface model of the lumen and camera pose estimates for each image or frame are required for this task. Camera pose parameters, which define camera alignment, are determined for six degrees-of-freedom. The size of each frame projected as a strip on the surface model depends on the longitudinal movement of the camera. The projected frames are concatenated, and the cylinder is unrolled to produce the mosaic image. Further processing, such as applying surface domain blending, improves the quality of the mosaic image.
