The studies on radiometric camera calibration of multispectral camera of the BiLSAT satellite is presented in this work. During the study, various dark images and flat-field images have been taken, and deviations from ideal has been investigated. Various sources of error have been studied and the non-homogeneous response of the CCD is explicitly modeled. Images have been corrected according to the models and the results have been discussed.

Opti-acoustic stereo imaging Saç, Hakan; Leblebicioğlu, Mehmet Kemal; Salor Durna, Özgül; Department of Electrical and Electronics Engineering (2012) In this thesis, opti-acoustic stereo imaging, which is the deployment of two-dimensional (2D) high frequency imaging sonar with the electro-optical camera in calibrated stereo configuration, is studied. Optical cameras give detailed images in clear waters. However, in dark or turbid waters, information coming from electro-optical sensor is insufficient for accurate scene perception. Imaging sonars, also known as acoustic cameras, can provide enhanced target details under these scenarios. To illustrate these...
Radiometric Cross-calibration of Goktiirk-2 with Landsat 8 Demirhan, Ismail Hakki; Deveci, Husne Seda; Sakarya, Ufuk (2017-05-18) Radiometric calibration studies need to be done during the life-time of a satellite. In this paper, reflectance-based cross calibration was conducted at Tuz Golu LandNet site in 2016 using Goktiirk-2 and Landsat 8 imageries. Using near simultaneous images of the satellites under the same atmospheric conditions reduces the effect caused by reflection differences of light. Cross calibration method can he conducted when the satellite sensors have similar bandwith. Even though observing visible bands is the bas...
Atmospheric Effects Removal for the Infrared Image Sequences Ozsarac, Seckin; Akar, Gözde (2015-09-01) Accurate correction of atmospheric effects on data captured by an infrared (IR) camera is crucial for several applications such as vegetation monitoring, temperature monitoring, satellite images, hyperspectral imaging, numerical model simulations, surface properties characterization, and IR measurement interpretation. Atmospheric effects depend on the temporal changes, i. e., year, season, day, hour, etc., and on the geometry between the camera and the measured scene, i. e., line of sight. The orientation a...
Determination of the position and orientation of rigid bodies by using single camera images Kilic, Varlik; Platin, Bülent Emre (2007-07-04) This study aims to present a new reconstruction method which enables reconstruction of 3D configuration of an object using single camera images. A secondary planar target which is a white circle with two internal black spots, one is located at the center, is used. The proposed reconstruction method is monocular and non-iterative. The elliptical contour and spot center locations of the target in an image is used to determine the 6-DOF configuration parameters of an object, on which the secondary target is ri...
Automatic target recognition and detection in infrared imagery under cluttered background GÜNDOĞDU, ERHAN; KOÇ, AYKUT; Alatan, Abdullah Aydın (2017-09-14) Visual object classification has long been studied in visible spectrum by utilizing conventional cameras. Since the labeled images has recently increased in number, it is possible to train deep Convolutional Neural Networks (CNN) with significant amount of parameters. As the infrared (IR) sensor technology has been improved during the last two decades, labeled images extracted from IR sensors have been started to be used for object detection and recognition tasks. We address the problem of infrared object ...
