立体图像对校正技术在三维显示中的应用

基于相机阵列的立体视差图像获取是3D立体显示技术的关键步骤之一,它为立体显示提供了丰富多彩的图像源;由于平行摆放的阵列相机拍摄得到的视差图像没有梯形失真和垂直视差,经3D显示设备后不会使观众产生视疲劳,因此,人们在视差图像获取时常采用时平行摆放的相机阵列.然而,在实际的操作中是很难达到这样理想的条件;本文针对常用的非平行摆放的双相机,经由图像校正的处理方法,来获得相同条件下平行式相机拍摄的效果;通过实验表明,该方案简单易行,效果良好,经3D自由立体显示后,观看的舒适度得到了提高.

Image rectification method and its application in stereo image acquisition

The acquisition of stereo images pairs based on camera area is one of key techniques in 3D display.It provides a great deal of content for 3D display.Because the array stereo camera with a parallel configuration does not produce trapeziform distorition and vertical parallax.so the vision fatigue can be minimized,when viewers watch 3D program.It is very difficult to achieve this parallel configuration in reality,this article aims at the stereo images obtained using toed-in cameras configuration which is usua...
