外文摘要：TH-1 satellite loading three-line array stereoscopic camera， can scanning 3 times from different directions on the same region or target within the time for about 1 minute， conducive to regional monitoring or target instantaneous change monitoring。 Based on the time difference of forward， nadir and backward images of the three-line-array camera of TH-1 Satellite， this paper gives a method to get regional dynamic change image by processing of geometric and physical consistency under the principle of photogrammetry， and to construct the model of change detection by the quantitative results of change detection under the improvement and optimization of noise filtering algorithm。 The experimental results show that， by using the detection results of forward， nadir and backward images of the three-line -array camera of TH-1 Satellite， moving distance and velocity can be accurately calculated， and quantitative monitoring of topography changes can be achieved， which not only has temporal resolution， but also can't be achieved by other environmental monitoring satellites。 It's significant for flood， fire， clouds， or motion detectors。 TH-1 satellite is China's first generation of transmission photogrammetry satellite。 With the more satellites networking operation， and higher spatial and temporal resolution， The TH satellites will play a greater role in the field of Earth observation。 This article merely uses the principles of photogrammetry to consider photography deformation from different directions， and thorough study will aim at shadow and sun elevation angle， to fully realize the monitoring of changes in topography and moving targets。
