To solve existing problems in modeling facade of building merely with point feature based on close-range images , a new method for modeling building facade under line feature constraint is proposed in...
For the first time the basic principle to unify advantages between active sensors and the simultaneous capturing of an image for an extended area of dynamical 3D applications in close range is given...
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 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...
There are generally two kinds of LIDAR, airborne and terrestrial. Terrestrial LIDAR is outstanding for its high accuracy, hyper speed and high density. A single range image of terrestrial LIDAR usuall...
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...
The modelling of complex objects and sites involve the acquisition of a large number of texture maps and range images; each one of them representing a particular viewing angle. These views must be c...
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...
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...
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...
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 ...
We have developed a new type of 3D measurement system which enabled us to obtain successive 3D range data at video rate with an error within ±0.3%In this paper, we try to reconstruct realistic colored...
The aim of this paper is to present two problems where straight lines were used as the primary source of control.The first problem is the orientation of images using vertical and horizontal lines for ...
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...
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...
