Zhangli Lan, Xiaofan Yang · Jisuanji gongcheng · 2008
This paper analyzes algorithms of gravity model, Hough transform, circle fitting, and spatial moment operators. An improved algorithm of laser spot center location is given after theoretical analysis and experiment, which can improve the location precision and anti-interference performance efficiently, and is suitable for real-time measurement. The algorithm is used in a laser deflection measurement system installed on Taipingzhang bridge and Anwen bridge of Yuqian expressway.
