Registered technology is the most critical technology in augment reality. Based on traditional linear model camera calibration method, a camera calibration algorithm is proposed based on identifying four feature points, and it is put into magic book augment reality systems,which can enhance the users＇ experience. The algorithm is simple,and able to adapt to a variety of occasions. All numerical solution process in the algorithm is linear so that the computation is easy and accurate. Calibration tasks can be done by identifying only four feature points, which reduces the image processing difficulty and extends the available range of the template. Experimental tests prove that the algorithm has very high value for the development of augment reality systems.
