This dissertation proposes a methodology for attitude correction by matching two different representations of the same environment. This is accomplished by match- ing features extracted from an image of the driving environment (measurement) to a pre-defined expectation of how the environment should look (map). A mobile mapping system (MMS) is developed as a platform for collecting the data necessary to conduct these tests. Using sample images, features are investigated for proper- ties that generalize easily between the virtual and physical worlds. This problem is formulated specifically for cases in which mountains are visible, allowing for the use of the horizon contour as a low-dimensional waveform in which to search for features. Once processes for achieving alignment using feature-based methods are developed, they are applied to data-sets consisting of images taken while the MSS moves through an environment. System performance is enhanced by the use of Kalman filtering to predict the dynamic motion of the system and mathematically account for it in estimation of attitude. The system developed in this dissertation is proven to work for orientation correction on a vehicle traveling approximately 35 mph in a rural environment.
