- W2354412996 abstract "Camera distortion is one of the important factors which affect accuracy of geometric measurement and three-dimensional reconstruction based on image.The images of straight spatial lines become curves in perspective projection because of distortion,and we can calculate the radial distortion parameters through the invariability of collinearity of the points on the line.In view of the gradient characteristics of camera distortion,this paper presents a method of camera radial distortion parameters calculation based on numerical digit.First,express first-order radial distortion in scientific notation as X×10-m,then calculate its index m and mantissa X successively,until it meets the accuracy set before.Finally,simulation experiments and real experiments are presented and they confirmed the correctness and efficient of the method." @default.
