WebCalibrate a camera using aruco markers. Parameters This function calibrates a camera using an Aruco Board. The function receives a list of detected markers from several views of the Board. The process is similar to the chessboard calibration in calibrateCamera (). The function returns the final re-projection error. calibrateCameraAruco () [2/2] WebYes, you need to choose a physical unit and then use it consistently, for describing your camera calibration object (chessboard) and your aruco marker coordinates, and then you will get answers back in the same coordinate system. The physical unit can be whatever you like, but metres are my favourite as well. :) – Chungzuwalla Aug 23, 2024 at 2:32
