Abstract
The application belongs to the technical field of precision measurement and intelligent manufacturing, and discloses an aero gear tooth surface appearance parameter set optimization system and method based on a multi-photometric algorithm, which comprises the following steps: a multi-photometric stereo algorithm is used to light the damaged surface of an aero gear tooth from multiple angles, and pictures of the damaged surface under different illumination directions are taken; based on the taken pictures of the damaged surface under different illumination directions, the surface normal is calculated, and the construction of the local damage profile of the surface is completed; the corresponding appearance parameters and geometric parameters of the constructed local damage profile are calculated; after the parameter calculation is completed, the parameter importance and the damage contribution calculation are completed through the constructed appearance parameter optimization model, and the appearance parameters are screened and optimized.
