Systems and methods for extracting and measuring motion from images capture during capsule endoscopy in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, an endoscope system configured to generate a spatial index of images captured along a passageway includes a processor and a camera configured to capture a plurality of images as the camera moves along a passageway, wherein the processor is configured to compare sets of at least two images from the plurality of images, determine motion of the camera along the passageway using the sets of at least two images, determine the distance the camera traveled along the passageway at the point at which an image in each of the sets of at least two images was captured, and generate a spatial index for the plurality of images by associating distances traveled along the passageway with the images.
