三目视觉测量系统在风洞试验中的应用研究
Application Research of Trinocular Vision Measurement System in Wind Tunnel Test
摘要
Abstract
Aiming at the application feature of the stereovision measurement in wind tunnel test,a trinocular stereovision measurement system based on linear CCD is designed.The cylindrical lens system based on biotar lens is fixed on the focal plane of CCD,which is used to convert the point light to linear light,and to reduce the lens distortion simultaneously.Adjusted by three-DOF mechanism to CCD,measurement target can form image nearby the focal plane.The virtual calibration target,constructed with coordinate measuring machines,is used to compute the transformation parameter accurately.Example application results show that the system can track the trajectory of the three-degree-of-freedom virtual flight system,and measures the mechanical dump of free-oscillation system accurately.关键词
