The constructing environment 3D models and dynamic textures

For constructing environment 3D models and dynamic textures, we utilize an image-based approach to calculate sparse point clouds from 2D images, which are then used to reconstruct the 3D model of the real scene. After reconstructing the model, in order to reduce the computational load for graphics processing and improve the performance of the UAV simulator, we must simplify the 3D model. Here, we employ the model simplification algorithm in Meshlab for this purpose.
