共有四个坐标系,一个运动坐标系即PhysicCoordinate,打印坐标系PrintCoordinate 图像坐标系ImageCoordinage CCD坐标系CCDCenterCoordinate,现在的需求是如何实现这几个坐标系互相转换。如何用面向对象的方式去实现这几个坐标系互相转换。用继承或者泛型或者接口的方式,或者更好的方式实现。
PhysicalCoordinate.ToImageCoordinate()//运动坐标系中的点转换为图像坐标系中的点

PhysicalCoordinate.ToPrintCoordinate()//运动坐标系中的点转换为打印坐标系中的点

ImageCoordinate.ToPrintCoordinate()//图像坐标系中的点转换为打印坐标系中的点

转换的关系式:ToImageCoordinate.X=PhysicalCoordinate.X*K+B; 其中K,B为double类型的变量。对应结构体中的TransCoordinate.XGain_Image(增益值),TransCoordinate.XOffset_Image(零点值)
