一种环状编码标记点偏转变形的自矫正方法

A self correcting method for revolved deformation of annular encoding markers

文章提出了在摄影测量或者计算机视觉中用到的环状编码标记点的一种矫正方法。编码标记点广泛应用于摄影测量或机器视觉,可以快速简单地实现目标检测和目标匹配。在对环状编码标记点进行检测时,标记点图案因拍摄角度而发生偏转变形,对解码的准确性会产生很大影响,所以文章提出了一种基于仿射变换的无需干预自动矫正方法,从而提高解码的准确率。

In this paper,a correction method of annular coded markers used in photogrammetry or computer vision is proposed.Coded markers are widely used in photogrammetry or machine vision,which can quickly and easily achieve target detection and target matching.In the detection of annular coded markers,the revolved deformation of the marker pattern due to the camera angle will have a great impact on the accuracy of decoding.Therefore,this paper proposes an automatic correction method based on affine transformation without intervention to increase the accuracy of decoding.
