首先在分度头上标定加速度计，得到其零点和灵敏度，然后分别在离心机和转台上进行转速实验。

First we calibrate the accelerometers on dividing head to get the offset and sensitivity, then do the rotation experiments on centrifugal machine and rotating floor.

基于差分图像确定投影原点的点弧线投影极值新算法，可快速获取仪表指针和分度线参数，且能区分分度线长短。

The image subtracting method and the point to arc projection extremum algorithm can derive the pointer and scale marks quickly, and separate the long and short graduation line.
