Study of high-accuracy image alignment key technologies
Guo Qin · Infrared and Laser Engineering · 2007
A high-accuracy image alignment method is described.Through high-accuracy image matching and image correction,achieves to align images taken by different ways and sensors in the same region with different resolution and characteristics.The technology takes extracting characteristic point as the guidance,uses one kind of specific image matching method,obtains the same-name control point,constructs the irregular triangular net,decomposes the image into various triangles region,in each triangle within the scope of each triangle realizes the high-accuracy images alignment.
