The advantages of making 3D models based on point cloud data and oblique images are as follows:
1.High-accuracy model with the accuracy level of surveying and mapping.
2.Model objectification: combined with the traditional two-dimensional system, convenient for later database management.
3.Texture authenticity: each point cloud data has a three-dimensional coordinate, which can improve the accuracy of image positioning; the oblique images after registration automatically matches texture for each building surface, and realizes the automatic texture pasting of the three-dimensional model, so as to make the texture of the model the most authentic.
