非接触式浮体六自由度监测系统研究

提出了一种非接触式浮体六自由度运动测量与分析系统。该系统由视频采集模块、三维计算模块、用户交互模块3 部分构成。视频采集模块用来获取不同视角的图像信息；三维计算模块融合了改进的摄像机自标定技术、立体视觉特征点检测技术、六分量解算方法等，目的是求得物体6 个自由度的运动情况；用户交互模块提供了定点可视的物体姿态及角度变化信息，方便用户进行分析计算。实测证明，该测量系统设备简单，重构速度快，能适应复杂的海上环境并能够实现远距离监测，满足浮体测量使用要求。

Non-touched system for 6D motions of model surveillance

This paper presents a system for measuring and analyzing 6D motions of model with non-touched style.There are three modules including video capture,image processing and user interface.Video cameras are used to capture the motion of the model at each moment,and improved self-calibration technology,feature point extraction technology in 3D vision and six dimensional calculation methods are used to get the motion in six degrees.User interface makes it easy to get the information at any time and any angle of view.Experiment in real environment has proved that the system is simple to use and with high efficiency.It can work in complicated environment and long distance.
