Can I reference the two papers, that is Benchmarking Structure from Motion Algorithms of Urban Environments and Tanks and Temples Benchmarking Large Scale Scene Reconstruction.

The value of 90% or 95% accuracy x means that for all the closest points of the vertices of the reconstruction model on the ground-truth model, 90% or 95% of them have a distance less than x. The value of 0.02 m, 0.075 m, or 0.075 m completeness x% means that for all the closest points of the vertices of the ground-truth model on the reconstruction model, x% of them have a distance less than 0.02 m, 0.05 m, or 0.075 m. A smaller 90% and 95% accuracy value mean higher accuracy and a larger 0.02 m, 0.05 m, or 0.075 m completeness value means higher completeness.
