摘要
随着测量仪器智能化、自动化要求的日益提高,视觉检测系统自动标定、甚至自标定成为一种必然趋势。以往的视觉标定技术或者需要外部实体高精度靶标介入,或者采用多图像标定(依靠多图像和相机姿态的关联),需要人手工介入,过程繁琐,效率低,精度有限。本文提出了一种可用于三维视觉测量系统的自标定解决方法,在检测系统中内置一个高精度标准件,通过引入一条光路来进行标定,使标定可以做到实时、自动、快速,克服了以往标定方法的弊端。经过理论分析和多项实验,效果良好。
With the fast development of the intelligence and automation in the measurement system, the auto self calibration become a trend. Former calibration method applied either an outer high precise target or used more than one picture so they need manual help and is low efficient and precise. In this essay, we bring a self calibration method for the 3D vision measurement system. We built in a high precise target and another optical path. As a result, we can calibrate the system real-time and automatically. The result is well under theoretically analysis and experiments.
