WEIGHTED GEOMETRIC OBJECT CONSTRAINTS INTEGRATED IN A LINE-PHOTOGRAMMETRIC BUNDLE ADJUSTMENT
line photogrammetry object reconstruction geometric constraints weighting mathematical model adjustment accuracy architecture
2015/1/6
The line-photogrammetric bundle adjustment is a new approach for the 3D reconstruction of polyhedral objects, with several advantages. Observing lines instead of points and integration of additional o...
CONSTRAINED LINE- PHOTOGRAMMETRIC 3D RECONSTRUCTION FROM STEREOPAIRS
line photogrammetry relative orientation 3D reconstruction mathematical model
2015/1/6
Objects and scenes encountered in close-range photogrammetry, vision metrology and virtual reality applications may often be adequately modeled as specific combinations of straight lines and/or line-...
In close-range images, normally a large number of geometrical features is available. For photogrammetrists, the detection of shapes such as straight lines is very useful. These features are very helpf...
3D Measurement System Using Line Laser for Archeological Artifacts
Digital Archeology Laser-beam Jomon-pottery 3D-measurement
2015/1/6
We developed ortho-projection and drawing system for reduction of record work of archeological artifacts. But, in this system, there are lacks of data. They were caused by position of source-light (ph...

Window system enables the establishment of integrated environment of digital close range photogrammetry which is based on object-oriented-technique centering around event by reinforcing the interface ...
STAGGERED LINE ARRAYS IN PUSHBROOM CAMERAS: THEORY AND APPLICATION
Sensors Camera Performance Analysis Simulation Photogrammetry Remote Sensing
2014/12/29
Using pushbroom sensors onboard aircrafts or satellites one needs - especially for photogrammetric applications - broad image swaths and high geometrical resolution together. To accomplish both demand...
In this paper, we propose a new scan line optimization method for matching the triplet of images. In the present paper, the triplets are initially matched using an area based local method. The cost is...
A novel camera calibration method for fish-eye lenses using line features
Photogrammetry Calibration Camera Geometric Close range Sensor
2014/9/9
In this paper, a novel method for the fish-eye lens calibration is presented. The method required only a 2D calibration plane containing straight lines i.e., checker board pattern without a priori kno...
Automatic Registration Of SAR And Optical Image Based On Line And Graph Spectral Theory
