Abstract
The present paper provides information about imagery and navigation systems of the Russian high resolution satellites "Resource- P". Models of image geolocation used for photogrammetric processing of information from all types of imagery systems are designed. Design of these models is based on two task solutions: correct processing of the measurement information and geometric calibration of the imagery systems. <br><br> It is shown that for high-precision interior orientation parameters adjustment of the high-resolution "Geoton" instrument the method of self-calibration should be used. The technology of calibration activities is considered. Distinctive features of calibration of the hyperspectral and wide-swath imagery systems are noted. It is represented in the paper that after calibration the root mean square error (RMSE) of measured geodetic coordinates of objects on images do not exceed 10 m. <br><br> Examples of the obtained models practical application for photogrammetric processing of images from “Resource-P” satellites are shown.
Highlights
In 2013 and 2014 two Russian Earth remote sensing satellites “Resource-P” No1 and No2 were successfully launched
complex of wide-swath multispectral imagery (CWMI) includes sensors of high (HR) and average (AR) spatial resolution each of which carries out imagery in the panchromatic channel and 5 multispectral channels in the 96/480 km swath
For photogrammetric processing of the Earth surface images from all types of satellite imagery instruments the present paper solves the following tasks: – development of models for video data geolocation taking into consideration specific character of the imagery instrument operation and algorithms of the measurement information processing; – development of technology for the geometric calibration of imagery instruments based on geometric calibration ranges; – indication of results of the practical application of processing models for acquisition of output information products
Summary
In 2013 and 2014 two Russian Earth remote sensing satellites “Resource-P” No1 and No2 were successfully launched. Satellite imagery instruments are a high spatial resolution sensor (“Geoton”) [Arkhipov and others, 2014], hyperspectral imagery instrument (HSI) and a complex of wide-swath multispectral imagery (CWMI). “Geoton” sensor forms an image in the panchromatic channel having resolution 0.7 m (nadir) and in 6 narrow spectral ranges having resolution 2.1 m in the 38 km swath. For photogrammetric processing of the Earth surface images from all types of satellite imagery instruments the present paper solves the following tasks: – development of models for video data geolocation taking into consideration specific character of the imagery instrument operation and algorithms of the measurement information processing; – development of technology for the geometric calibration of imagery instruments based on geometric calibration ranges; – indication of results of the practical application of processing models for acquisition of output information products
