Following the occurrence of a typhoon, quick damage assessment can facilitate dispatch house repair and disaster insurance works. Employing deep learning method, this study used aerial photos Chiba prefecture obtained following Typhoon Faxai in 2019, to automatically detect evaluate roof damage. This comprised three parts: training model, detecting using trained classifying level The detection ...

Digital aerial cameras have replaced analogue aerial cameras in several countries. The development for operational aerial photogrammetry started with the line scan camera ADS40, followed by Z/I Imaging DMC and Vexcel Imaging UltraCam. Recently the line scan camera Jena Optronik JAS-150 was introduced. The capacity of the UltraCam was enlarged by replacing the used CCDs with 9μm pixels over 7.2μ...

Traditional manned airborne surveys are usually expensive and the resolution of the acquired images is often limited. The main advantage of Unmanned Aerial Vehicle (UAV) system acting as a photogrammetric sensor platform over more traditional manned airborne system is the high flexibility that allows image acquisition from unconventional viewpoints, the low cost in comparison with classical aer...

The use of archival or historical photography for photogrammetric purposes often involves a lack of data concerning the aerial cameras employed, difficulties in identifying control points on the photos and inappropriate conservation of the photography. When camera calibration parameters are unknown, they should be estimated by means of a self-calibrating bundle adjustment. Several calibration m...

Retargeting aims at displaying a photo with an arbitrary aspect ratio, wherein the visually/semantically prominent objects are appropriately preserved and visual distortions can be well alleviated. Conventional retargeting models built upon perception of photos from family pre-specified communities ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlin...

The goal of this research is to test an empirical line radiometric calibration of airborne digital scanner ADS40 data from Leica Geosystems, for remote sensing applications in general and to demonstrate the potential of ADS40 data for archaeological prospection in detail. In this study we present the first results of multitemporal flight campaigns with two different generations of ADS40 sensor ...

Abstract The article outlines the possibilities for assessing geological conditions related to fording beds of large lowland rivers, based on low-ceiling ad hoc aerial photos, and current state art utilization remote-sensing methods in engineering studies. conducted research provided a confirmation that set sensors installed onboard an vehicle enables recording images, analysis which allows det...
