High-precision 3D Modeling Method Based on Terrestrial Image Sequences for Alpine-gorge Area
The traditional measurement methods cannot adapt to the arduous topography of alpine-gorge area.Aiming at the topographical features of alpine-gorge area,we will introduce a general terrestrial method of multi-baseline photogrammetry basing on digital camera here,and then the paper mainly studies the metrization method of common digital camera and matching method of the digital image sequences of alpine-gorge area.Through the metrization of common digital camera,the efficiency of terrain data collection will increase in the alpine-gorge area,and the requirements of operations on the image control and algorithm will reduce.The combination of seed points and multiple constraints in multi-baseline stereo matching will help to solve many problems,such as shading,severe distortion between the lett image and the right one,and the inconformity of scale.The modeling process stated above is quite fast and highly precise,and the three-dimensional modeling experiments show that the relative accuracy can reach from 1/8000 to 1/12000.
