A precise geometric correction method for remote sensing image being constrained in a vector graphics of seismic exploration engineering

A precise geometric correction method for remote sensing image being constrained in the vector graphics of seismic exploration based on feature points is researched. The characteristics of a remote sensing image and a seismic exploration vector graphics are analyzed at first, which can generate digital maps in seismic acquisition. Then, regarding vector graphics as constraint, a mathematics model is built, combining together overall transform and local transform. After the transform parameters are calculated by least square method, the remote sensing image data is sampled again. So, the remote sensing image is corrected. After that, a procedure of a precise geometric correction for remote sensing image is put forward, which can be used in seismic acquisition. In the end, the practical application maps show the feasibility of this technology and procedure.
