摘要
Abstract
Rapid and high-accuracy measurement of river topography and changes in riverbed erosion and deposition is of great significance for studying river evolution.In response to the lack of practical guidance and unstable accuracy of SfM-MVS in river model experiments,the 3D models with higher resolution,better visualization effect,and comparable measurement accuracy than TLS can be obtained based on SfM-MVS after experimental calibration.Experimental research has been conducted on the accuracy optimization of SfM-MVS in 3D reconstruction of river models from three aspects:image quality and image preprocessing,lens distortion and camera calibration methods,and measurement network design and optimization.After optimization,the measurement accuracy of the 3D models is significantly improved,which can provide general guidance for the application of SfM-MVS in river model experiments from the aspects of preliminary preparation,image acquisition,image processing,and accuracy evaluation.关键词
