Quantification Method for the Uncertainty of Matching Point Distribution on 3D Reconstruction
ISPRS International Journal of Geo-Information, 2020 Matching points are the direct data sources of the fundamental matrix, camera parameters, and point cloud calculation. Thus, their uncertainty has a direct influence on the quality of image-based 3D reconstruction and is dependent on the number, accuracy,
