An improved stereovision scheme using one camera and a composite lens array

摘要

The stereovision scheme is a method to extract the three-dimensional information of the original object from two or more images of it. In the conventional scheme, more than two cameras are used to acquire numbers of images with different perspectives. As the numbers of cameras are increased, the complexity of the entire system is also increased and there can be many difficulties such as camera calibration and vibration in the conventional method. In this paper, an improved stereovision scheme using single camera and a composite lens array is proposed. In the proposed system, only one camera and a composite lens array is required and the complexity of the entire system is decreased. With the use of a composite lens array, it is possible to improve the performance of the system compared with the method using a conventional lens array. The proposed method is proven to be useful by simulation and experimental results.
