Fast terrain matching algorithm based on radial projection transform
Jian Liu · Infrared and Laser Engineering · 2006
In order to satisfy the different needs of submarine navigated performance in the different navigation steps,the fast terrain matching algorithm based on radial projection transform is presented.The main steps of the algorithm are as follows: Firstly,the image is projected to one dimension curve by the radial projection transform of the image.Secondly,the matching position and rotational angle in the image are searched by the phase correlation.Because searching two dimension image is transformed to searching one dimension curve by the radial projected transform,the matching speed is efficient.
