findChessboardCorners fails with 24x23 chessboard pattern

asked 2017-07-18 02:32:10 -0500

I use openCV functions in LabView (make dll) to do camera calibration. Function findChessboardCorners works good with 22x21 chessboard pattern and less (14x13, 8x7, ...), but 24x23 and greater causes a crash of LabView. Can someone help?

opencv comes with some premadecalibration apps.

please use those, NOT the outdated and no more maintained c-api code, labview is using (we cannot help you with that)
