【Abstract】 The eyeglasses frame trajectory is a three-dimensional curve, which contains plentiful information of the parameter of eyeglasses frame, and the way to deal with is very important in measure field of eyeglasses frame and affect the precision and veracity of the measurement. A method is present to pick up the parameter such as A, B, Circle, ED, EDA, LD, LDA and Curve, by trajectory curve data fitting, plane shift, circumvolvment and projection. A lot of experiments are shown that the proposed algorithm with high anti-jamming is beneficial to improve the stability and veracity, and has widly practicability to enhance the performance of production.更多还原
