摘要
摄像机标定技术对于精确的双目视觉定位起着关键的作用。了解摄像头标定的原理有助于采用合理方法减小标定结果误差。本文介绍的摄像机标定方法标定结果误差小。摄像机标定过程中用到三个坐标系,它们之间的转换关系是摄像机标定的基础。采用内外参数分离的标定方法,通过具体实验分步标定了摄像机的内参数和外参数,实验过程简单,标定精度较高。
Camera calibration technique plays a key role for precise binocular visual positioning.To understand the principle of camera calibration contributes to adopt the rational method to reduce calibration results error.This paper introduces a calibration method which result error is small.In the process of camera calibration we need three coordinate systems,and the conversion relations between them is the basis of camera calibration.The internal and external parameters of camera were demarcated by the separation of internal and external parameters calibration,through the specific step-by-step experiment.The experiment process is simple,and shows high accuracy in calibration.
