The Application of Spatial Scene Matching Based on SURF in Cruise Missile Terminal Guidance
Yongjun Qiao, Xiaofang Xie, Lei Shi, Dedong Li · 2010
Aiming at overcoming the drawback of cruise missile for only using downward images to implement scene matching, presents a novel approach that gets the template image from the projection of 3D digital terrain at random viewpoints and random angles, which ensures the camera of missile can capture the images with desired angle. In scene matching, the SURF (Speed-up Robust Features) algorithm that based on invariant features is introduced for image matching; the software suite of MultiGen-Paradigm is used for the creating and rendering of 3D digital terrain. The analysis and experiment underlines the approach's usefulness in cruise missile terminal guidance.
