双目立体视觉的摄像机标定方法研究的中期报告摘要：双目立体视觉是一种基于图像的三维重建方法，通常需要对双目摄像机进行标定，以获取摄像机内参和外参参数。本研究在已有双目摄像机标定方法的基础上，着重探讨了解决标定过程中出现的多个棋盘格标定板不能同时被摄像机捕获的问题，并提出了一种新的标定方案。根据该方案，我们通过将多个标定板分为两组，每组相邻的标定板互相平移一定距离，从而实现了两组标定板的同步捕获。同时，为了简化标定过程，我们还在标定板上加入了二维码，用于自动识别并记录标定板的位置、姿态和序号。实验结果表明，该方案可以有效解决多个标定板不能同时被摄像机捕获的问题，且标定结果的准确性也得到了验证。关键词：双目立体视觉；摄像机标定；棋盘格标定板；二维码识别Abstract:Stereovisionisamethodofthree-dimensionalreconstructionbasedonimages,whichusuallyrequiresthecalibrationofbinocularcamerastoobtaintheintrinsicandextrinsicparametersofthecameras.Basedontheexistingbinocularcameracalibrationmethods,thisstudyfocusesonsolvingtheproblemthatmultiplechessboardcalibrationboardscannotbecapturedbythecameraatthesametime,andproposesanewcalibrationscheme.Accordingtothisscheme,wedividedmultiplecalibrationboardsintotwogroups,andeachadjacentcalibrationboardinthegroupwastranslatedacertaindistancetoachievethesynchronouscaptureofthetwogroupsofcalibrationboards.Atthesametime,inordertosimplifythecalibrationprocess,wealsoaddedQRcodestothecalibrationboardstoautomaticallyidentifyandrecordtheposition,attitude,andserialnumberofthecalibrationboards.Experimentalresultsshowthatthisschemecaneffectivelysolvetheproblemthatmultiplecalibrationboardscannotbecapturedbythecameraatthesametime,andtheaccuracyofthecalibrationresultshasalsobeenverified.Keywords:stereovision;cameracalibration;chessboardcalibrationboard;QRcoderecognition.
