摘要
设计并实现了一种摄像机内外参数的自动标定方法:提出了一种无伪的标定模板图像角点的自动提取,以及与对应物理空间坐标的匹配算法;进而,以此结果作为标定基础数据,采用Tsai[TsaiRY.Aversatilecameracalibrationtechniqueforhigh-accuracy3Dmachinevisionmetrologyusingoffthe-shelfTVcamerasandlenses[J].IEEEJournalofRoboticsandAutomationRA,1987,3(4):323-344.]的两级标定法,获取摄像机的内外参数;以LabVIEW为平台,开发了一个摄像机自动标定系统,并进行了实验验证.
On the basis of Tsai'scalibration technique for high-accuracy 3D machine vision metrology using offthe-shelf TV cameras and lenses. IEEE Journal of Robotics and Automation RA, camera calibration model, the base data are required as the input to the calibration arithmetic. This paper put forwards a method of automatic camera calibration, including no false corner detection in calibration board image, homologous corner mapping in 2D and 3D space, and the fulfillment of the whole calibration process. The accomplishment of the method is based on LabVIEW.
