图像像素距离与空间距离变换公式的求解

Solution of Transform Formula between Image Pixel Distance and Space Distance

在图像处理中,最后求得的物体的边缘位置是它在图像中的像素位置,很多情况下需要求得图像中的两点在实际空间中的距离。文中推导了图像像素与实际空间距离的变换公式以及相关参数的求解公式。

In image processing, the final position of the edge of an object derived it in the image pixel location,in many cases need to obtain images of the two points in real space distance.This paper derived the image pixels and the actual spatial distance transform formula and camera images of some parameters of the solution.
