A SWEEP-PLANE ALGORITHM FOR THE SIMPLIFICATION OF 3D BUILDING MODELS IN THE APPLICATION SCENARIO OF WIND SIMULATIONS
3D City models Automated Processing BRep
2018/11/9
As the number of virtual 3D city models is steadily increasing, so are the possible applications that take advantage of them. 3D models can be used for applications that range from simple graphic visu...
INFRARED ROTATION PLANE RADAR CHANGE DETECTION
Infrared Rotation Plane Radar Change Detection Depth Information Mixed Gaussian Background Modeling
2018/5/15
The existing change detection method mainly stays on the pixel-level, which is very susceptible to light, shadow, etc. And the complex calculation and analysis for each pixel reduce the detection effi...
PLANE-BASED REGISTRATION OF SEVERAL THOUSAND LASER SCANS ON STANDARD HARDWARE
Terrestrial laser scanning registration plane-to-plane correspondences stochastic modelling large networks
2018/6/5
The automatic registration of terrestrial laser scans appears to be a solved problem in science as well as in practice. However, this assumption is questionable especially in the context of large proj...

CCD Image Digital Aerial Photogrammetry Camera Iimage Edge Image Processing Modelling
2015/12/23
Aiming at uneven illumination and low contrast of large plane array CCD images, this paper presents an effective algorithm to extract uneven illumination from images and enhance the contrast by using ...
BUILDING ROOF RECONSTRUCTION FROM LIDAR DATA AND AERIAL IMAGES THROUGH PLANE EXTRACTION AND COLOUR EDGE DETECTION
Laser Sanning (LiDAR) Building Rconstruction Aerial Photogrammetry Data Integration Urban planning Image Pocessing
2015/12/23
In this paper a strategy for 3D reconstruction of building roofs from airborne laser scanning and aerial images is discussed. In order to keep it as general as possible, no predefined primitives or gr...
A MODIFIED H-α PLANE FOR THE EXTRACTION OF SCATTERING MECHANISMS FROM DUAL CIRCULAR POLARIZATION SAR DATA
Compact polarimetry Dual Circular Polarisation mode classification producer’s accuracy entropy alpha
2016/1/15
Cloude–Pottier entropy and α-angle are two important parameters for the interpretation of fully polarimetric data. They indicate the randomness of the polarisation of the back scattered waves and the ...
