Based on the meaning of object state in tracking theory, a novel representation for object state is proposed, which differs from traditional one with only locomotors state. In this thesis, model parameters may also represent the object state in according to different situations. Thus, the localization and characters of object are filtered synchronously, which accelerates the matching and tracking speed in real-time tracking system, especially for complicated object. In summary, this thesis studies the methods of template obtaining, updating and matching, etc.

从跟踪理论的目标状态所表示的意义出发，提出了将目标模型参数与运动参数同时作为目标状态进行滤波的方法，改变了传统方法中只利用目标运动状态的情况，在确定目标位置的同时能够匹配目标轮廓或其他特征，对于复杂的目标，可以快速鲁棒的完成视频帧中的模板匹配和跟踪。

In order to get a high tracking speed,a constraint Kalman filter is used to predict the position of feature point,in this way the region of image processing is minished and the speed of image processing is improved.

在视觉跟踪阶段，为了提高跟踪速度，利用约束卡尔曼滤波器建立预测器，对物体图像的未来位置进行预测，这样就减小了图像处理的区域，提高了图像处理的速度。

The conclusion is that the extent of the zenith blind zone was restricted by three parameters: maximum azimuth angular velocity of tracking mount, flight level and airspeed of the target. In astronomical coordinates (reference mark is north latitude 43. 9°), analyzed is the effect of azimuth angular velocity, acceleration and altitude angular velocity, acceleration etc. Some formulae were given to compute all correlative quantities.
