MANAGEMENT AND VISUALIZATION OF HUGE RANGE IMAGES AND DIGITAL IMAGES
LiDAR Spatial modelling Visualization Multi-scale Representation Geo-information management 3D R-tree spatial index MBB
2015/12/23
Generally speaking, a large number of range images data will be generated in the process of collecting 3D structure information of huge building based on the 3D LIDAR scanning technology. For instance...
Rectification of Digital Close Range Images: Sensor Models, Geometric Image Transformations and Resampling
Resampling Rectification Image Restoration
2015/12/14
Rectification may be considered as the transformation process of digital images carried out to obtain distortion free versions of the
images. Transformation parameters are obtained by using ground co...
Indoor Navigation by Using Segmentation of Range Images Obtained by Laser Scanners
laser scanning localization mapping navigation robotics segmentation tracking
2015/11/23
This paper proposes a method to reconstruct the trajectory of a moving laser scanner on the basis of indoor scans made at different positions. The basic idea is that a position with respect to a measu...
Automatic morphological pre-alignment and global hybrid registration of close range images
Laser scanning Registration Algorithms Matching Automation
2015/8/24
The point cloud alignment problem has always attracted the interest of the researchers. Two are the procedures usually applied for the close range surveys: the ICP method with all its variants, and th...
INCREMENTAL PROCEDURE FOR RECOVERING ENTIRE BUILDING SHAPE FROM CLOSE RANGE IMAGES
Urban Building Reconstruction Close Range Image Computer Vision Incremental Processing
2015/5/25
This paper describes a method for recovering entire 3D shape of a building from an image sequence. This is a kind of “Shape and Motion recovery” problem in the computer vision field, whereas the conve...
DEVELOPMENT OF INTEGRATION AND ADJUSTMENT METHOD FOR SEQUENTIAL RANGE IMAGES
3D data Range image Point cloud ICP algorithm Self-calibration bundle adjustment
2015/5/21
With increasing widespread use of three-dimensional data, the demand for simplified data acquisition is also increasing. The range camera, which is a simplified sensor, can acquire a dense-range image...
A GENERALIZED FACTORED STOCHASTIC MODEL FOR THE OPTIMAL GLOBAL REGISTRATION OF LIDAR RANGE IMAGES
LIDAR Registration Adjustment Laser scanning
2015/3/24
Surveying complex shapes or very large entities by laser scanners often requires the registration of a sufficient number of partial 3-D
range images in order to completely reproduce the model of the ...

Integration Range Data Automation Free Condition 3-D Measurement System
2015/1/6
Most conventional approaches to integrate range images from plural view points utilize range images obtained under some artificial restrictions set on movement of the target or measurement system by p...
AN EXPERIMENTAL STUDY ON REGISTRATION THREE-DIMENSIONAL RANGE IMAGES USING RANGE AND INTENSITY DATA
Point cloud Registration Intensity image Range image Automation Keypoint
2014/5/8
Laser scanner is noncontact instrument to measurement of spatial data. It measures object surfaces as point series and visualize as point cloud. One of the important steps on processes of laser scanni...
AUTOMATIC CORRESPONDENCE AND GLOBAL REGISTRATION OF RANGE IMAGES FOR 3D MODELING
Three-dimensional Modeling Representation
2015/6/1
A free-form object must be acquired from multiple viewpoints to make its complete 3D model. These views are then
registered by establishing correspondence between them. Pair wise registration of the ...
