Camera calibration is the process of determining the parameters of a camera.The classification of camera calibration was listed in this paper.Some mathematical model of calibration was given too.A new method was presented to make control points.Traditional camera calibration needs a model with many control points.These points should be evenly distributed in space

it is difficult to make the model and high cost.In this paper

a calibration board was made and moves the board parallel in its normal direction

the moving board is a three dimension model

moreover

it could increase control points significant

the board is much easier to make than three dimension model

it makes the process easier and reduces cost of the calibration.The calibration parameters of camera were calculated by different control points group;get the mean value of these parameters.The method presented in this paper has been tested with real data.Experimental results show that the method is practical

accurate and robustness.
