An Improved Camera Calibration Method Using the Fiducial Marker System

摘要：

Above all, we pointed out that the basis of the calibration algorithm based on the grid points is the matrix, which indicates the mapping relationship between the target surface and the image surface. But to our disappointment, it is the correspondence problem of the calibration points that exists in the current way to calculate it. Therefore, the fiducial marker system is used for reference here, which includes the definition of selection criteria of fiducial markers, analysis of their recognition rate from the environment, and the wrong recognition rate from each other. Next, a improved method is brought up including the extraction of the calibration points, the calculation of their image coordinates, and a group of related formulas. In the end, we consider our algorithm is very proper for indoor environments which can be controlled easily, and proved it with great efficiency and liability by the experiments as well.
