The invention discloses a method for identifying honeycomb edges from honeycomb core surface measurement data. The method comprises the following steps: performing two-dimensional coordinate transformation on collected honeycomb core surface three-dimensional data, identifying corner points in a two-dimensional plane projection image of a honeycomb core through a corner point detection algorithm,wherein the corner points comprise a human-shaped vertex, a Y-shaped vertex, a pseudo vertex and unrecognized missing corner points; based on the proposed corner type judgment algorithm, sequentiallyidentifying two endpoints of the honeycomb edge, determining one endpoint during adjacent edge identification, and determining the other endpoint through local analysis of the identification vertex; and effectively eliminating pseudo vertexes in the implementation process of the honeycomb edge, supplementing missing vertexes, and achieving stable and high-precision honeycomb edge recognition. According to the method, the data processing problem of honeycomb core measurement is effectively solved, and the method is flexible, high in precision and good in robustness, and the measurement requirement of the honeycomb core surface after actual machining can be met.
