Digital Close-range Photogrammetry Using Artificial Targets
A procedure for an automatic search and measurement of artificial targets in digital images for elose-range photogrammetric applications is presented. Photographs taken with a sem i metric 6x6 camera were digitized by the "ASTROSCAN" at the Sterrewacht Leiden. The especially designed targets contain a circular barcode for automatic identification. It is shown that this procedure improves both p...
متن کاملVisibility Analysis of Point Cloud in Close Range Photogrammetry
The ongoing development of advanced techniques in photogrammetry, computer vision (CV), robotics and laser scanning to efficiently acquire three dimensional geometric data offer new possibilities for many applications. The output of these techniques in the digital form is often a sparse or dense point cloud describing the 3D shape of an object. Viewing these point clouds in a computerized digit...
متن کاملA New Digital Interest Point Operator for Close-range Photogrammetry
The process for automatic DTM, DSM generation in close-range photogrammetric applications is always a need but under investigation for many years so far. It is well known that close range conditions are wide big different from the aerial ones, basically due to the three reasons: (a) the perspective in images appears to be larger; (b) the existence of repeated patterns at every turn and (c) the ...
متن کاملAdvances in Close-Range Photogrammetry
This paper presents a general overview of notable developments in close-range photogrammetry (CRP) over the past four decades, during which time both automated processes were introduced and the full transition from film-based to digital imaging cameras occurred. With these developments and more recent innovations centred upon so-called structure-frommotion approaches to network orientation, alo...
متن کاملUsing in Volume Computing of Digital Close Range Photogrammetry
It is important to know cutting and filling volumes in many survey, engineering and mining works. Volume calculation, generally, are completed with classic surveying methods. The trapezoidal method (rectangular or triangular prisms), classical cross sectioning (trapezoidal, Simpson, and average formula), and improved methods (Simpson-based, cubic spline, and cubic Hermite formula) have been pre...
