一种单镜头立体成像方法的研究

Research of stereo imaging method by using single lens

分析了当今主流商用立体摄像方法的原理和优缺点,特别针对双目立体摄像机标定难的缺点,提出了一种单镜头双孔立体成像方法。该方法只需一个镜头,通过在镜头前加装2个小孔,控制2个小孔分时开合,即可摄取场景的不同侧面,由此便得到了一幅双目立体图像对。实验结果表明,该立体成像方法可以在避免复杂的多摄像机标定的情况下取得较好的双目立体成像效果。该方法的创新点在于只需一台摄像机、一个镜头在固定位置就可以拍摄双目立体图像,避免了对多个摄像机进行标定,减轻了立体成像中摄像机标定的难度。

The principles,advantages and shortcomings of stereo imaging methods widely used in business are introduced.In allusion to the difficulty of camera calibration,a stereo imaging method by using single lens and two pinholes are proposed.In this way,only single lens is needed and two pinholes are installed in front of the lens.Furthermore,these two pinholes should be alternately opened and closed,The different profiles of a scene can be captured,which can be used as a pair of binocular stereo images.The experimental result shows that the effective binocular stereo images can be obtained in this way,which avoids the complex multi-camera calibration.The innovation is that only single lens is needed to get a binocular stereo vision in a fixed position.It reduces the complexity of stereo camera calibration.
