Description
Technical field
The invention belongs to Aeronautical Test Technology field, more particularly to the pneumatic rudder face calibration of a kind of aircraft based on machine vision
Device.
Background technology
The rating test of the pneumatic rudder face of aircraft is one of the element task of unmanned plane research and development.In the experiment of In-Flight Performance
It, need to be to rudder faces such as the aileron of aircraft, wing flap, rudder and elevators in order to provide reliable performance test data in research
Carry out angular shift calibration.
Tradition board a plane pneumatic rudder face calibration generally use two methods.The first is using the artificial of graduated scale measurement
Measurement method after manipulating control surface deflection, measures the air line distance of rudder face cusp and adjacent airfoils, the method is by measurer deformation and people
The influence of work error in reading, measurement accuracy is low, and cannot carry out real-time data acquisition.Second is that standard is installed on rudder face
The measurement method of sensor, the method are higher to sensor mounting location deviation and zero-bit adjustment deviation sensitivity, therefore, pass
Sensor installation accuracy requires high, adjustment process complexity, it is difficult to meet rudder face calibration, the adjustment requirement of high-effect high-quality.
