According to the realistic needs of the unmanned aerial vehicle (UAV) scene matching navigation, image registration method is proposed, based on linear features of the airborne synthetic aperture radar (SAR) and optical images containing typical man-made objects. Firstly, improved line segment detection (LSD) method is proposed to extract linear features of the image; Secondly, we construct the control lines and design an image registration method. Finally, precise automatic image registration is achieved based on the affine transformation model. The experimental results show that the proposed method has high registration accuracy for the SAR image and optical image, which is different in intensive, rotation and translation. The computation time is substantially reduced, and it is possible to meet some of the real-time applications.
