Web9 de mai. de 2024 · I'm using OpenCV to detect calibration targets (specifically asymmetric circles, but the question applies to symmetric circles too). When the number of pixels in a particular circle is small (diameter less than about 30-40 pixels, from experience), findCirclesGrid works fine, but if the diameter is too large None is returned. Web8 de jan. de 2013 · Currently OpenCV supports three types of objects for calibration: Classical black-white chessboard Symmetrical circle pattern Asymmetrical circle pattern Basically, you need to take snapshots of these patterns with your camera and let OpenCV find them. Each found pattern results in a new equation.
