摘　　要：从视觉技术角度出发,根据透视变换原理,提出了一种圆环转换为矩形的改进方法,提高了转换速度,并通过实验,经纠正畸变、图像分割、圆形识别、图像展开、插值及边缘检测等步骤,对展开结果进行了验证。This paper gives out how to measure the small objects on the inside wall of a cylinder precisely on the stand of technology of machine vision,especially the way of transferring the ring to rectangle rapidly. To make it out, it needs to use the technology of machine vision, include some steps such as image aberration, image segmentation, the identification of roundness, transfer ring to rectangle, interpolation, edge detection and so on.
