This application relates to generating a three-dimensional vector object, representing a feature within a scene, by analyzing two-dimensional vector objects representing the feature in a stereo pair. The two-dimensional vector objects are analyzed using stereo vision algorithms to generate the three-dimensional vector object. Results of the analysis derive three-dimensional positions of corresponding points of the two-dimensional vector objects. The three-dimensional vector object is generated based on the results of the stereo vision analysis. The three dimensional vector object can be compared to three-dimensional digital point models. The three dimensional vector object can also be compared to another three-dimensional vector object generated from a stereo pair that are captured under different conditions.
