三维目标定点跟踪方法

A METHOD OF TRACKING A SPECIAL POINT OF THE 3-D TARGET

提出了一种基于模型的线组合目标跟踪方法，该方法将三维目标前Ｋ幅二维正投影图像作为模型与当前二维投影图像相结合求取一组系数，从而通过解线性方程求得目标上任一点在当前二维正投影中的位置，这种方法首次解决了三维目标跟踪中的平移、尺度和旋转不变性及大面积遮挡问题，实现了对目标的任意点（包括内部点）作为瞄准点的定点跟踪。

A target track method track method besed on linear combination of models has been pro-posed. In this method a 3-D target is represented by the linear combination of sequencial pro-jection images of the 3-D target and a group of coefficients is acquired, so the position of anypoint in the current pointed out by solving a group of linear equations. The problems ontracking any point as an aim point,non-variety in spacial transform and covering the targeton a larger area have first been solved.
