风洞试验中,模型姿态是实验数据修正的重要环节,测量的准确与否对实验结果有着重要影响。从风洞试验实际出发,提出一种基于双目立体视觉的风洞模型姿态测量技术,并介绍了该技术在风洞中的应用。试验表明文中使用的方法与美国兰利研究中心31-inch Mach 10风洞中使用的视觉姿态测量系统精度相当,具有广泛的使用前景。 In the wind tunnel test, the attitude of the model is an important part of the experimental data correction. The accuracy of the measurement has an important influence on the experimental results. Based on the wind tunnel experiment, this paper proposes a wind tunnel model attitude measurement technology based on binocular stereo vision, and introduces the application of the technology in wind tunnel. Experiments show that the method used in this paper is comparable to the visual attitude measurement system used in the 31-inch Mach 10 wind tunnel at Langley Research Center and has a wide range of applications.
