Our proposed method consists of three main parts: first, both the high-resolution multi-spectral image and the 3D geometry data are used for feature extraction,
To optimize the computational efficiency and reduce the required processing time, the proposed approach is implemented based on prior knowledge of the scene
After removing the atmospheric component, we estimated the linear deformation velocity and residual topographic error.. After removing the latter component, we estimated the time
It can be seen that whether changing the angle or length, the evacuation efficiency is not as good as the original simulation, and some even longer than normal export shape
named U xoy is calculated by combining the Alpha Shape algorithm with RANSAC ( Random Sampling Consistency ) algorithm, and then the projection point set of central axis on YOZ
There are two basic approaches to describe the shape of an object surface: point segmentation based on criteria such as the proximity of points, and direct estimation
The individual classification method assumes that each 3D point is independent and assigning a unique semantic label with local features automatically, which can
According to the PDR method of positioning error size and indoor road network structure, the buffer distance is determined reasonably and the buffer centering on
