Manual surveys still represent the most widely used means for inspecting and evaluating pavements. Manual rating of pavements through windshield surveys to identify the types of surface cracking and other distresses leads to relatively slow evaluation. Furthermore, the survey crew must sometimes physically be in the travel lane to evaluate the pavement,(More)
Intermittent loss of the gps signal is a common problem encountered in intelligent land navigation based on gps integrated inertial systems. This issue emphasizes the need for an alternative technology that would ensure smooth and reliable inertial navigation during gps outages. This paper presents the results of an effort where data from vision and(More)
We present results of an effort where position and orientation data from vision and inertial sensors are integrated and validated using data from an actual roadway. Information from a sequence of images, which were captured by a monocular camera attached to a survey vehicle at a maximum frequency of 3 frames/s, is fused with position and orientation(More)
