基于DSP的视频稳像技术的研究
Research of electronic image stabilizationg technique based on DSP
随着摄像设备应用的日益广泛，摄像平台变得越来越多样。通过车载摄像系统、手持摄影设备、飞机或者舰船摄影平台等得到的视频信号往往会因为摄像机的运动而发生抖动。视频抖动不仅会影响视觉效果，容易使观看者产生晕眩进而导致误判和漏判，并且给进一步的图像分析带来困难。可见，如何将这些视频信号转化为高质量的稳定视频具有重要的应用价值。文中提出了一种基于DM642 的灰度投影算法的电子稳像系统,系统采用TI公司的TMS320DM642专用图像处理芯，选取灰度投影算法作为本文实时电子稳像算法的基础。
With the prevalence of camera device, video shot can be easily obtained. However, such video obtained in moving carrier has the shaking problem resulted from camera’s shacking. Video shacking not only leads to bad video effect but also leads to false judgment or missing judgment, which are harmful to the next image object trailing. Thus, the require of stabilization of video is more and more important. This article provides an electronic image stabilization system based on the method of pray projection algorithm of DM642. This system used the specialized image - processing chip TMS320DM642 made by TI company pray projection algorithm is chosen as the base part of real-time electronic image stabilization algorithm.
