A 3d Model of Castle Landenberg (ch) from Combined Photogrammetric Processing of Terrestrial and Uav-based Images

چکیده
In this paper we demonstrate the workflow of 3D modelling and photorealistic texture mapping based on close range imagery acquired with a mini-UAV (Unmanned Aerial Vehicle) and in terrestrial mode. For generation of a highly accurate 3D model, a combined photogrammetric processing of these images was required. The conducted workflow consists of the following steps: project planning, flight planning, terrestrial and aerial image acquisition, camera calibration, control point measurement using GNSS (Global Navigation Satellite System), measurement of control and tie points in the images using the photogrammetric close range processing software Photomodeler 6, modelling and texturing of the object and visualization of the finalized model. Finally we achieved an excellent high resolution textured 3D-Model of the castle Landenberg with combining terrestrialand UAVPhotogrammetry.

متن کاملData Fusion and Multi-Criteria Decision Making for Producing Oil and Gas Resources Potential Maps (Case Study: Saracheh Zone, Qom Province)
This paper focuses on the application of Geoinformatic methods (simultaneous using of remote sensing, geographic information system, global positioning system, terrestrial and aerial photogrammetry) in optimal operation and exploration risk reduction of oil and gas reservoirs. To approach the purpose, two aspects of remote sensing (satellite image) and terrestrial and aerial photogrammetry have...
متن کاملTrue-orthophoto Generation from Uav Images: Implementation of a Combined Photogrammetric and Computer Vision Approach
This paper presents a photogrammetric methodology for true-orthophoto generation with images acquired from UAV platforms. The method is an automated multistep workflow made up of three main parts: (i) image orientation through feature-based matching and collinearity equations / bundle block adjustment, (ii) dense matching with correlation techniques able to manage multiple images, and true-orth...
متن کاملAn Evaluation on Fixed Wing and Multi-Rotor UAV Images Using Photogrammetric Image Processing
This paper has introduced a slope photogrammetric mapping using unmanned aerial vehicle. There are two units of UAV has been used in this study; namely; fixed wing and multi-rotor. Both UAVs were used to capture images at the study area. A consumer digital camera was mounted vertically at the bottom of UAV and captured the images at an altitude. The objectives of this study are to obtain three ...
متن کاملTarget detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV
In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...
