For some special blade section, an accurate partitioning algorithm for feature point cloud is presented to avoid the drawbacks of traditional convex hull algorithm. On this basis, the method based on graph transformation is used to extract the chord length. The experimental results show that these two algorithms have strong generality, high accuracy and efficiency, can meet the testing requirements of blades.
