Research on Low Altitude Image Acquisition System
نویسندگان
چکیده
In order to acquire quick, high resolution, affordable aerial photographs, an unmanned helium filled airship system equipped with a non-metric digital camera was developed in Chinese Academy of Surveying and Mapping. To meet the potential demand of large scale photogrammetric applications, the non-metric digital camera was calibrated rigourously based on the bundle adjustment with additional parameters and the workflow for generating digital orthophotos was proposed. At the paper end, the promising results obtained from an application with the system are shown and evaluated.

Low altitude aerial image sequences have the advantages of high overlap, multi viewing and very high ground resolution. These kinds of images can be used in various applications that need high precision or fine texture. This paper mainly focuses on the photogrammetric processing of low altitude image sequences acquired by unmanned airship, which automatically flies according to the predefined f...
متن کاملApplications of Low Altitude Remote Sensing in Agriculture upon Farmers' Requests– A Case Study in Northeastern Ontario, Canada
With the growth of the low altitude remote sensing (LARS) industry in recent years, their practical application in precision agriculture seems all the more possible. However, only a few scientists have reported using LARS to monitor crop conditions. Moreover, there have been concerns regarding the feasibility of such systems for producers given the issues related to the post-processing of image...
متن کاملRobust Fuzzy Content Based Regularization Technique in Super Resolution Imaging
Super-resolution (SR) aims to overcome the ill-posed conditions of image acquisition. SR facilitates scene recognition from low-resolution image(s). Generally assumes that high and low resolution images share similar intrinsic geometries. Various approaches have tried to aggregate the informative details of multiple low-resolution images into a high-resolution one. In this paper, we present a n...
متن کاملSuper-resolution of Defocus Blurred Images
Super-resolution is a process that combines information from some low-resolution images in order to produce an image with higher resolution. In most of the previous related work, the blurriness that is associated with low resolution images is assumed to be due to the integral effect of the acquisition device’s image sensor. However, in practice there are other sources of blurriness as well, inc...

Background: Prospectively electrocardiography (ECG)-triggered high-pitch spiral coronary computed tomography angiography (CCTA) is a unique scan mode for dual-source CT (DSCT). Our reports aim to compare image quality and radiation dose of CCTA using high-pitch spiral or sequential acquisition mode in patients with low and stable heart rates. Materials and Methods: Patients with low and stable ...
