Along with the rapid development of computer technology , video codec technology has been greatly improved. However , as people 's desire for video information , a single view video information is no longer able to meet the requirements of the people . In recent years, with 3D stereoscopic video technology visual function and multi- view video technology has been widespread attention , and become a research hotspot. According to statistics, the information obtained from outside humanity , about 60% -75% from the visual system . Therefore, in order to meet the growing needs of the visual system , is bound to develop and video information is closely related to the processing, handling, and a series of advanced technologies , including video information processing, the most important issue is how to transfer huge data on an effective amount of compression. As we all know , the video contains a three-dimensional depth information of the scene , so the natural scenery is more realistic characterization . However, in three-dimensional video, the amount of data to be much larger than the single-channel video , so the stereoscopic video compression efficiency is particularly important. Meanwhile, with the development of computer technology , stereo vision theory will be widely used in automatic navigation, industrial measurement , virtual reality , biomedical and military reconnaissance and other fields. In the stereoscopic video , the disparity estimation is a focus of the study , the whole system has a very important role. In this paper, three-dimensional video of the disparity estimation done related research, due to the traditional dynamic programming algorithm is carried out only in the global energy scan line optimization , the resulting disparity map has a distinct \energy function to improve and strengthen the constraints between scanning lines , making the \making accuracy improved.
