Aviation aircrafts and their spare parts often experience deformation due to the complex work conditions, measuring the deformation distribution and deformation process have scientific significance and application value. The measurement results provide reliable reference data for aviation equipments structure design, mechanical properties analysis and study on aerodynamics. The traditional measuring methods were reviewed, their advantages and shortages were analyzed. To realize fullfield deformation measurement on aviation equipment, the 3D optical measurement method videogrammetry was presented and discussed, key technology and future development trend were also predicted. 
