摘要 3D显示器的再现立体景深与立体对图像的视差有关,视差的大小取决于拍摄设备的原理正确性。由双镜头3D拍摄设备获得左右格式的立体对图像,根据图像同名点检测视差信息,再由检测出的视差数值来计算景深。视差采用灰度极值法,提取立体对图像的特征行像素灰度值波形图,通过灰度波形的极值判别同名点并检测前景与背景标志物体的视差数值。实验表明行像素灰度极值法有助于快速计算3D图像的同名点视差信息。 3D display reproduction of the three-dimensional depth of field and three-dimensional image of the parallax,the parallax size depended on the correctness of the principle of shooting equipment. In this paper,by the double-lens 3D shooting equipment to obtain the left and right format of the three-dimensional image,according to the image of the same name to detected parallax information,and then detected by the parallax value to calculate the depth of field. The grey value method was used to extract the pixel gray value waveform of the image. The parallax value of the foreground and background marker object was determined by the extreme value of the gray waveform.Experiments showed that the row pixel gray value method helps to quickly calculate the parallax information of the same name of the 3D image.
