A novel no touch measuring method for traditional products was put forward and a precise model of Direct Linear Transform was presented for the aberration in the images occurred at every turn. Rectangle mark tag and location parameter are no longer needed in this algorithms. A method of tolerance reckon by curve equation was also provided. In order to raise the operation speed Hough circle detection method was improved. In the meantime circle detection method to images with more than one circle was applied, so that the concentricity calculation is possible.

论文的创新点是，提出了传统机械产品的非接触式测量方法，特别针对图像采集环节最容易出现的畸变现象，提出了一种严密的直接线性变换模型，该算法既不需要在影像上有框标，也不需要有摄影机内外方位参数的起始近似值，具有显著优点；提出了利用曲线的方程来确定公差的方法，对传统的Hough圆检测方法进行了改进，提高了检测速度，同时将圆检测用于存在多圆的图像，使多圆的同心度检测成为可能。
