Modern navigation systems rely heavily on the Global Positioning System GPS to correct inertial measurement unit IMU error drifts. However, due to unreliability og GPS in certain scenarios, there is a great desire to create an inexpensive navigation solution to augment GPS based navigation. Vision-aided navigation is such a solution where information from captured imagery can supplement inexpensive on-board IMUs in bounding navigational errors that arise from IMU drifts. Optical flow information obtained from this imagery allows for the evaluation of structure-from-motion, motion-from-structure, and egomotion.
