基于特征跟踪的视频判读方法

针对发射场火箭初始段漂移量测量，提出并实现一种新的判读方法，主要采用特征点或特征区域检测与目标跟踪相结合的方法，利用各种数字图像处理手段，借助辅助开发工具，计算目标在各帧图像中的坐标，实现对目标运动的高精度判读。该方法既具有自动判读的功能，又具有适应性强的半自动判读功能，能够计算出多个目标点的精确位置；同时还具有对判读结果的实时校验的功能。实验结果表明，该方法判读精度高，速度快，具有较好的稳定性和适应性，有向其他目标或领域扩展的能力。

An Approach of Digital Video Image Processing Based on Feature Tracking

A new approach of measuring the drift of rockets in the initial launching stage is presented and developed. In this method, the feature points-areas are combined detecting with target-tracking. Selected image processing methods and tools are used for accurate position calculating of multi-targets. Experimental result shows that the approach is precise, robust and fast and can be extended into other similar application fields.
