A Camera Calibration Method using Quadratic Curve Fitting

摘要：

　　The camera calibration is an essential part in the machine vision,the camera calibration is to establish the relationship between the camera image pixellocation and scene position,the approach is based on the camera model,solving the model parameters of the camera image coordinates and world coordinates from the known feature points.Using the camera calibration method based on quadratic curve,this article selects a template consists of two concentric circles and two concentric ovals.We shot 4 images in different directions,and use different combinations of three of the four images to calibrate camera.Thus we can calculatethe various parameters of the camera.
