| 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。

| Abstract: | 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... |
