A Research For Algorithm Of Three-Dimention Reconstruction

Textile is one of the industries which takes use of computer-aided design and computer graphics technology. In the clothing virtual display system, the research of how to create a three-dimensional model by a series of photos has brilliant significance. Image-based three-dimensional reconstruction is the method based on a number of pictures of objects and scenes to restore the three-dimensional model. This method is a crossing field, referred to computer image processing, computer graphics, computer vision and pattern recognition, and many other disciplines.Currently, there are a lot ways to obtain three-dimensional information. You can use the existing modeling software such as 3DMax, Maya and other three-dimensional model structure, such software can accurately build the man-made objects, and add solid rendering is widely used in film and television works. The operation of the software is very complex, takes a long period for modeling and requires skilled operators of such software, making production costs high.In addition, a number of instruments and equipment can be used to obtain three-dimensional model, and the object reconstructed by such equipment has a very high accuracy. Modeling time is relatively short with this equipment, but the process and the equipment itself always cost so much, and it can not deal with the object enormous.In view of these advantages and disadvantages of classic methods for three-dimensional information, a new idea that obtains three-dimensional information from two-dimensional images has been proposed. The method takes use of two-dimensional images, or digital camera images from the cameras to calculate the three-dimensional information. This method does not require high costs, the core algorithm is easy to understand and implement, is the focus of current research. Modeling is just based on multi-angle image sequence. This does not only reduce the workload of staff and increase the efficiency.
