基于图像分割的三维立体匹配改进算法

传统基于分割的立体匹配算法所采用的局部匹配方法误匹配率较高,同时平面拟合也具有一定的局限性。为了获得高准确率的视差图,本文将改进的局部匹配方法与全局匹配相结合,来获取初始视差图;同时利用曲面拟合的方法对各分割区域进行处理,并在区域合并中提出了新的判决准则。仿真实验结果表明,本文算法能够获得较高精度的视差图,实现了各纹理区域之间的平滑过渡,同时,在低纹理区域和被遮挡区域也取得了比较理想的效果。     

DVB-S2中三维传输方案简

According to the characteristics of DVB-S2 streams and 2D data transmission, three kinds of transmission modes based on the data link layer are provided in the DVB-S2 channel, and the corresponding transmission protocol stacks are also given. According to the regulation of transmission modes, the transmission efficiency is calculated in each case and then a comparison is made. Synthesizing various factors, we conclude that each transmission mode has its own advantages and disadvantages in different applications, and that none of them cannot be completely replaced by others.
