New linear approach for camera calibration based on improved SUSAN detector
基于改进的SUSAN法的摄像机线性标定方法

A new linear approach with radial distortion model for camera calibration was designed and realized. Firstly, SUSAN comer detector was combined with edge detection and false comer removal to enhance its speed and accuracy. Secondly, the improved SUSAN detector was used to obtain the sub-pixel coordinates of the comers. Thirdly, a camera model with radial distortion was established to calculate the intrinsic and extrinsic parameters of the camera. The experimental results and error analysis demonstrate high accuracy and efficiency of this approach.
