基于共聚焦图像序列的深度估计方法
DEPTH ESTIMATION BASED ON CONFOCAL IMAGE SEQUENCE
摘要
Abstract
In this paper, a depth estimation approach based on confocal images is proposed. In order to realise the estimation of depth information of scenes, we use virtual aperture technique to set an array of cameras to acquire multi-angle images for obtaining confocal images sequence through synthesis and use it as the data resource of focus ranging to make focus analysis. Aiming at the feature of confocal images, we combines clarity assessing algorithm with colour constancy assessing algorithm of the conventional focus ranging method and put forward a focus degree metric algorithm, which suites for the focus analyses of both strong texture area and weak texture area in images. Experimental results show that this approach has higher effectiveness in focus judgment and can gain a quite accurate depth estimation of scenes.关键词
