| 摘 要： | 提出了一种基于Hessian矩阵的亚像素精度结构光条纹中心提取算法．实践证明，该算法具有高精度、鲁棒性强等优点，其不足之处为运算量大、效率低．将原算法与阈值法结合，提出了算法的改进快速方法，很大程度上减小了算法的运算量，实现了结构光条纹中心线的实时提取．

| Abstract: | A method to detect the sub-pixel center of structured light stripe with Hessian matrix is proposed.Experiments show that the proposed method is characterized by high precision and robust.The disadvantages of this method are tremendous computation charge and limited real-time applicability.Combined the algorithm with the threshold method,a improved fast algorithm is presented.The improved algorithm drastically reduces the computation charge and implements high-accurate center extrication of structured light stripe with high speed.It advanced the structured light vision inspect to real-time applications. |
