The computer simulated sampling points with different grid cell sizes were generated and then interpolated into 10000 points with inverse distance weighted. Finally, the original value was compared with the interpolated value for the same grid cell to find the sampling error, and optimal sampling points were determined according to the allowable sampling error.

利用计算机按照不同的网格单元尺寸(如3×3,5×5,7×7等)进行采样,之后利用采样值进行IDW插值处理,将数据点恢复到原始的10000个,并把插值结果与原始值进行比较即可得到采样误差。

Based on the strong relationship about frames near by, the Author brought forward an particle filter algorithm importing weighted sampling about pre-frame in object tracking. The algorithm resolves the trickiness in traditional SIR algorithm which depends on statcmodcl acutely by importing proposal distribution. The algorithm can track object which movement is irregular.
