摘要
在图像前景抠图的基础上,提出一种对双视角图像视差计算以及对图像中目标物体景深估计方法。首先,对左右视图标记,提取标记图像中目标物体;然后利用前景抠图技术和二值化计算得到一幅二值化图像;最后计算左右二值化图像中对应目标物体的视差值,通过视差值判断目标物体在场景中的景深。实验结果表明,该方法计算简单,不需要图像采集设备外部参数,可以达到较高精度。
Based on the image foreground matting, a method of disparitycomputationand the estimation of the image depth in the double perspective of image is provided. First of all, on the double view of marking, the target marker image is extracted. Thena two value image is engendered using the two value calculationandforeground matting technique. Finally, the two value disparity of image corresponding objects is calculated, anddepth of the target objects in the scene is determined by parallax value. The results show that the method is simple in calculationwithoutexternal parameters of the image acquisition device, and can achieve high precision.
