Abstract
Distances between spatial features such as a clearance height of a bridge over a roadway are determined based on camera images captured in a moving vehicle. A stream of images is captured. The presence of bridge overpasses is recognized in the images. A range between the vehicle and the bridge overpasses is detected at which each respective image is captured. A height of each respective bridge overpass is photometrically determined according to the respective detected range, a respective location on the respective bridge overpass, and a calibration factor. A posted height is recognized in a respective image of a respective one of the bridge overpasses. The calibration factor is revised according to a discrepancy between the respective posted height and the respective photometrically determined height. In succeeding determinations of the monitored distances, the revised calibration factor is employed.
