摘要：The article presents a powerful and automated methodology to extract accurate image correspondences from different kinds of close- range image blocks for their successive orientation with a bundle adjustment. The actual absence of a commercial solution able to automatically orient markerless image blocks confirms the still open research in this field. The developed procedure combines different image processing algorithms and robust estimation methods in order to obtain accurate locations and a uniform distribution of tie points in the images. We demonstrate the capabilities and effectiveness of this method with several tests on closed or open sequences and sparse blocks of images captured by a standard frame (pinhole) camera, but also spherical images. An accuracy evaluation of the achieved 3D object coordinates with photogrammetric bundle techniques is also presented
