3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Satellite sensor geometric calibration satelitesensorsgeometriccalibration Use satellite ground calibration facilities or existing geographic information data (including digital orthophoto and digital elevation) that meet the geometric accuracy requirements Model, etc.), the process of regularly solving the internal and external orientation parameters of the surveying satellite sensor, and establishing a strict geometric model of the sensor. 3.2 Satellite sensor interior orientation parameters interiororientationparametersofsatelitesensors The parameters required to describe the position of the satellite image point in the image space coordinate system. Note. The orientation parameters of the satellite sensor include image principal point coordinates, principal distance, distortion parameters, etc. 3.3 Satellite sensor exterior orientation parameters exteriororientationparametersofsatelitesensors Describe the basic parameters of the position and orientation of the satellite sensor's photographic beam in the object space coordinate system and their changes over time. Note. The external orientation parameters of the satellite sensor include satellite orbit measurement data, the offset between the camera center and the orbit measurement, satellite attitude data, offset matrix, etc. 3.4 Alignmentmatrix Orthogonal rotation formed by the angle between the actual observation azimuth of the satellite sensor in the image space coordinate system and the satellite attitude measurement azimuth matrix. 3.5 Pointingfieldangle The angle between the position vector of the satellite sensor imaging device in the image space coordinate system and the X, Y axis. 3.6 Artificialtarget Feature targets that are pre-arranged manually and are easily identified on satellite remote sensing images.
