Background: Three dimensional image feature reconstruction is to establish a mathematical
model, which is suitable for computer representation and processing. It is the basis of processing,
operating and analyzing its properties in computer environment, as described in various patents.
Method: This paper introduces the present situation of the research on the reconstruction of 3D image
features, and analyzes the method of 3D image reconstruction. 3D feature image reconstruction is an
important branch of 3D image processing technology. Through the principle analysis and technology
research of 3D image reconstruction technology, the development status of the relevant research at
home and abroad is made detailed analysis. The different methods for surface rending technology,
volume rending technology, and stereo vision matching technology are analyzed; in addition, the
working principles and the existing problems are analyzed.
Result: Experiments have proved the performance of the correlation method, e volume rendering
technology can remodel real three-dimensional shape of the corn leaf better, the ups and downs of
edge of the corn leaf and drape, other details can be preserved, effectively improve the convergence
speed, and greatly reduce the running time and the number of iterations.
Conclusion: It provides the development direction for the 3D image feature reconstruction.
