Abstract

Abstract: A new method for corner extraction of camera calibration is presented.This approach does not require user manually select interesting point.To achieve this objective，a new calibration pattern is proposed that cans automatically selecting points.This method is easy implement，fast and high accuracy.

Key words: camera calibration, corner extraction, threshold

摘要： 描述了一种复杂背景下的快速角点识别算法。以往的方法在复杂背景下会产生大量的误差，为了实现复杂背景中的全自动定标设计了全新的标定图案，通过对拍摄图案的二值、边缘提取、查找连通性等操作实现对特征矩形的识别，从而确定棋盘格角点，完成自动标定。通过实验，该方法在复杂背景下仍能取得亚像素级别的角点定位。
