Blade running elevation measurement device and method based on binocular stereovision technology

Abstract

The invention aims to provide a blade running elevation measurement device and method based on binocular stereovision technology. The device comprises a light source, an inductance proximity switch, a helicopter blade mechanism, cameras, a guide rail and a graphic workstation, wherein the light source is arranged above the helicopter blade; the inductance proximity switch is mounted on the helicopter blade; left and right cameras are mounted on the guide rail, face the helicopter blade and are distributed at the two sides of the helicopter blade; and the two cameras are connected with the graphic workstation. The device is simple in structure, convenient to adjust, simple to mount and maintain and stable and reliable in working.

Description

technical field The present invention relates to an optical measuring device, and the present invention also relates to an optical measuring method, in particular to an optical measuring device and a measuring method for co-conic measurement. Background technique When the rotorcraft is flying, the blades will be slightly upturned to form an inverted cone. If the lift force is consistent, the blades will move on the same cone, which is usually called a common cone. If the lift force is inconsistent, the trajectories of the blades are not conical, and the heights of the blades are not equal. The co-conicity of the helicopter rotor is a main indicator of the rotor dynamic balance measurement. It is directly related to the safety of the helicopter and the quality of other important performances. It is an important inspection item in the production and maintenance of the helicopter. Since the measurement of co-conicity is often carried out under the dynamic condition of high-spe...

AI Technical Summary

Problems solved by technology

Since the measurement of co-conicity is often carried out under the dynamic condition of high-speed rotation of the blade, there have been problems in the past that are difficult to measure and poor in measurement accuracy.
