Abstract :
Optical sensors onboard an unmanned aerial vehicle (UAV) can collect high resolution images with small dimensions. Image mosaicking is necessary to cover a larger geographic area. This paper presents a novel approach to mosaicking UAV images automatically. The "Orthophoto Map" is based on Structure From Motion (SFM). This method can fully automatic mosaic generate a wide range, and with well visual effects, and no evident deformation. This method can not only get a panoramic image of wide range of areas, and can get the corresponding three-dimensional terrain model.
