Pre-Launch Absolute Calibration of CCD/CBERS-2B Sensor
Pre-launch absolute calibration coefficients for the CCD/CBERS-2B sensor have been calculated from radiometric measurements performed in a satellite integration and test hall in the Chinese Academy of Space Technology (CAST) headquarters, located in Beijing, China. An illuminated integrating sphere was positioned in the test hall facilities to allow the CCD/CBERS-2B imagery of the entire sphere...
متن کاملIn-flight absolute calibration of the CCD/CBERS-2 sensor data
The success of any remote sensing program is directly related to the knowledge of both spectral and radiometric characteristics of the sensors involved. The Brazilian remote sensing user’s community has explored the relationship between orbital radiometric data and biophysical data since the beginning of the nineties using the Thematic Mapper (TM) sensor as the main source of data. Since the fi...
متن کاملIn-flight absolute calibration of the CBERS-2 CCD sensor data.
Since the first images of the sensors on board of CBERS-2 (China-Brazil Earth Resources Satellite) satellite were made available by the National Institute for Space Research (INPE), users have asked information about the conversion of image digital numbers to physical data (radiance or reflectance). This paper describes the main steps that were carried out to calculate the in-flight absolute ca...
متن کاملRadiometric CCD camera calibration and noise estimation
Changes in measured image irradiance have many physical causes and are the primary cue for several visual processes, such as edge detection and shape from shading. Using physical models for charged-coupled device ( C C D ) video cameras and material reflectance, we quantify the variation in digitized pixel values that is due to sensor noise and scene variation. This analysis forms the basis of ...
متن کاملCCD camera full range pH sensor array.
Changes in colors of an array of optical sensors that responds in full pH range were recorded using a CCD camera. The data of the camera were transferred to the computer through a capture card. Simple software was written to read the specific color of each sensor. In order to associate sensor array responses with pH values, a number of different mathematics and chemometrics methods were investi...
