Integration and Precision Optimization of Open Ground Data in 3D Realistic Modeling of Water Conservancy Engineering Oblique Images
In order to improve the accuracy of traditional photography techniques,a three-dimensional real scene modeling method for water conservancy engineering combining oblique photogrammetry and aerial data fusion technology is proposed.The method adopts feature extraction based on SIFT operator and beam adjustment technology,as well as adaptive guided filtering mode,to improve model accuracy.The results show that the proposed model has a mean square error of 0.022m in the X direction,0.027m in the Y direction,0.035m in the overall plane,and 0.029m in elevation,all of which are better than the corresponding error values of ordinary air ground fusion models.The research method provides technical support for the refined management of hydraulic engineering.
