3D Building Modeling Technology
Image-object space integrated processing technology-based Automated object extraction and modeling
3D Building Modeling
Our technology can extract 3D man-made structures (its height and footprint coordinates) by volumetric shadow analysis (VSA) interactively. The VSA needs the direction (its azimuth angle and elevation angle) of the sun and the camera. If not available, but there is one known man-made height in the image, 3D man-made structures also can be extractred by VSA. Our technology can extract the 3D structures from online Google earth.
