Abstract: A bridge military load classification (MLC) assessment system may increase soldier survivability and/or engineer reconnaissance support to military decision-making process (MDMP) while reducing the required operator level of expertise. A set of “at distance” 3D dimensioning solutions may include soldier-guided, vector-based measurements, photogrammetry, and/or computer vision (CV) and augmented reality (AR) methodologies-enabling off image plane measurements along all three axes across the image through the image principal point. The solutions may include (1) single image with view of bridge feature that introduces two- or three-point perspective, (2) camera focal length, (3) camera sensor width, (4) laser rangefinder (LRF) vector to the image principal point, and (5) two lines traced along edges of the bridge to identify one vanishing point. A rapid MLC could be calculated from a considerable distance (greater than 100 meters) given an unobstructed “below-deck” view of the bridge.
