A STUDY ON GENERATING STEREO MOSAIC IMAGE USING VIDEO FRAMES
Myoung Jong · 2008
Recently, generation of high quality video sequences utilizing a camcorder has been possible owing to advances in video equipment technologies. Generation of mosaic images from high quality video sequences has been attempted by a variety of investigations. Especially, among the matter of investigation, many investigators have been interested in study on 3D information construction. For constructing 3D information using aerial photograph or video sequences, left and right stereo images should be prepared in overlapping area. In video sequences, left and right stereo images may be generated by mosaicing left and right sliced images extracted in consecutive video sequences. Very important step among the data processing for stereo mosaicing is to determine motion parameters for each video frame image. These motion parameters so examine the geometrical relationship between consecutive frame images that image registration could be performed between consecutive frame images. Using registered images, stereo mosaic images are generated. In this paper, methodology on determining relative orientation parameters in charge of the motion parameters using video frame images taken without GPS/INS geo-data is proposed. Because overlapping area between consecutive frame images taken in 30frames/1second frame rates is more than 90%, the proposed method make use of the process in step by step based on relative orientation, bundle adjustment and space resection algorithm using the aerial photography. Using determined relative orientation parameters, image registration is performed and left and right stereo mosaic images are generated. The result of experiment showed the determined relative orientation parameters, the left and right stereo mosaic images and anaglyphic image for stereo mosaic images.
