Calibration and Rectification of Fisheye Images Based on Three-Dimensional Control Field

Experimental study on satellite image adjustment based on rational function model

“…This experimental study utilizes a small number of control points and DEM to calculate the initial attitude angle correction value of the image and correct it, so then rapid orientation of satellite images in large areas. Through this production test, that mastering the relevant methods for regional network adjustment of high-resolution satellite remote sensing images, and based on the preliminary test results, revise the technical plan and production process flow, gradually improve and complete all experiments, Analyze the factors that affect the accuracy of adjustment for single satellite remote sensing images, we can summarize the advantages and disadvantages of the production process, accuracy indicators, and production efficiency of adjustment for single satellite remote sensing images [6,7] .…”

“…A strict sensor model based on collinear equation method,established a strict geometric imaging relationship between the image and the ground, but it is closely related to their respective sensor types, it requires obtaining the orbit and attitude parameters of the sensor, the form is complex and lacks universality. In order to effectively replace strict sensor models, some approximate generalized imaging models have been studied and proposed, the most famous of them is the Rational Function Model (RFM) [1,2,3] .…”
