3D BUILDING FACADE RECONSTRUCTION UNDER MESH FORM FROM MULTIPLE WIDE ANGLE VIEWS
Surface Reconstruction Digital Facade Models Global Optimization Multi-Image Matching
2015/8/7
The
central idea is to create a 3D point cloud. After comparison between object-space and image-space techniques, we choose the latter and
compute the depths of the pixels in each image using a corr...
Frequency combs are the rulers of light. By counting a wavelength’s many oscillations, they measure distance and time with extraordinary precision and speed.
Since the discovery of optical frequency ...
