“…There are traditional camera calibration methods, active vision camera calibration methods, and camera self-calibration methods for different camera lenses. Moreover, image-sampling methods are classified into nearest neighbor interpolation, bilinear interpolation, bi-cubic convolution, and B-spline interpolation according to different interpolation methods [10,11]. Image registration is a key step in image mosaicking.…”

Image mosaicking is one of the key technologies in data processing in the field of computer vision and digital photogrammetry. For the existing problems of seam, pixel aliasing, and ghosting in mosaic images, this paper proposes and implements an optimal seam-line search method based on graph cuts for unmanned aerial vehicle (UAV) remote sensing image mosaicking. This paper first uses a mature and accurate image matching method to register the pre-mosaicked UAV images, and then it marks the source of each pixel in the overlapped area of adjacent images and calculates the energy value contributed by the marker by using the target energy function of graph cuts constructed in this paper. Finally, the optimal seam-line can be obtained by solving the minimum value of target energy function based on graph cuts. The experimental results show that our method can realize seamless UAV image mosaicking, and the image mosaic area transitions naturally.
