This paper is devoted to the investigation and development of the algorithm for the log pile photogrammetry measurement on the basis of abuts detection and calculation of their diameters. The algorithm of abuts contours detection and refinement relies on the modified radial symmetry object detection algorithm. The combination of the following methods is implemented at the further stages of the ...

Laser altimetry has, and is continuing to have a profound impact on photogrammetry. This paper discusses the interrelationship between the two fields, identifies problems, and suggests a common research agenda. Surface reconstruction is an important application in photogrammetry. DTMs, for example, are as much an end result as an intermediate step for orthophoto generation and for object recogn...

In this paper the main problems and the available solutions are addressed for the generation of 3D models from terrestrial images. Close range photogrammetry has dealt for many years with manual or automatic image measurements for precise 3D modelling. Nowadays 3D scanners are also becoming a standard source for input data in many application areas, but image-based modelling still remains the m...

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...

This paper describes how we could combine the two most available systems for the purpose of surveying and documenting the architectural heritage, historical buildings and monuments. The two systems are digital photogrammetry (applied in a close-range context) and CAD. The product of this integration is a 3-D GIS application. In this application, close-range photogrammetry is used for the acquis...
