affine coordinate transformation

基本解释

Affine transformation as a coordinate transformation method can satisfy real-time, high conversion efficiency requirements, but it is still not accurate perfectly.
白板模式能够满足基本的课堂需求，但是录制授课内容、完善教学工具等进一步的功能尚未实现。
So the affine transformation between the model affine coordinate frame and the image affine coordinate frame has two adjustable parameters which will be applied to affine matching.
由于原点坐标是不确定的，因此仿射坐标架也是可以活动的，由该仿射坐标架建立的仿射变换也带有两个可以在一定误差范围内变化的调整参数。
On the basis of a special micro-feed mechanism, which is driven by a simple cam, a new polar coordinate interpolation algorithm, which is based on affine transformation, is presented.
在由凸轮驱动机械式微进给机构的基础上，利用仿射变换构建了一种新型的极坐标插补算法，可实现任意非圆轴的加工成形。
