چکیده

In this paper we introduced the principle of stereo imaging using linear arrays and its implementation in several imaging systems. A simulation study was conducted in which simulated IKONOS-I fore-, nadirand aft-looking images were produced using airborne AIMS images, IKONOS-I technical data, and a DEM. The attainable accuracy of ground points determined by the imagery is reported, considering various conditions such as number of GCPs, distribution of GCPs, errors in image and ground coordinates and others. It is concluded that the accuracy of ground points can reach about 2-3m with GCPs and 12m without GCPs. The experimental results of HRSC and MOMS-02P data validated the bundle adjustment software system designed and implemented for processing high-resolution satellite imagery.

Metric Evaluation Pipeline for 3d Modeling of Urban Scenes

Publicly available benchmark data and metric evaluation approaches have been instrumental in enabling research to advance state of the art methods for remote sensing applications in urban 3D modeling. Most publicly available benchmark datasets have consisted of high resolution airborne imagery and lidar suitable for 3D modeling on a relatively modest scale. To enable research in larger scale 3D...

Combining High Resolution Satellite Imagery and Airborne Laser Scanning Data for Generating Bareland Dem in Urban Areas

This paper proposes a framework for generating bare-land Digital Elevation Model (DEM) in urban areas by combining highresolution satellite imagery and Airborne Laser Scanning (ALS) data. Airborne laser scanners offer an efficient approach for 3D data acquisition. ALS data provides very accurate position and height information, but less direct information on ground objects’ geometrical shape, m...

Automatic Georeferencing of Aerial Images Using High- Resolution Stereo Satellite Images

For airborne surveys, direct georeferencing has become the primary source for EOPs (Exterior Orientation Parameters) determination since integrated GPS/INS (Global Positioning System/Inertial Navigation System) systems were introduced. However, there is still need for alternative indirect georeferencing since there are remote, inaccessible areas that lack a geodetic infrastructure and thus GPS/...

Sensor Integration and Calibration of Digital Airborne Three-line Camera Systems

The determination of the exterior orientation parameters is an essential pre-requisite for the evaluation of any imagery from terrestrial, airborne or satellite based sensors. Normally, this georeferencing processing is solved indirectly by using a number of well known ground control points and their corresponding image coordinates. Using a mathematical model for the relation between image and ...

Investigation on the Amount of Mortality of Iranian Oak Trees (Quercus brantii Lindi) using Satellite Imagery (Case study: Dashtebarm forests of Fars Province)

In recent years, oak trees in the Zagros forests have suffered a lot of fatalities for unclear reasons. Determining the rate and severity of forest crown density changes is important for the investigation and management of these forests. This research was carried out with the aim of determining the amount of crown cover changes in the forest area of Dashtebarm in Fars province under the influen...
