The moment-preserving thresholding method is used to pick-up targets, the masscentroid tracking algorithm and linear-fitting predicting approach are used to tracking targets.
采用矩持阈值分割方法提取目标，采用质心跟踪算法及基于线性微分拟合的记忆外推跟踪技术跟踪目标。

Aim: To measure mass, centroid and centroidal deviation of projectile body.
目的：对弹体的质量、质心及质偏进行测量。
