| 摘要: |
| 针对飞机尾旋运动研究中的姿态测量问题，提出一种基于双目立体视差原理的测量方法。通过两部相机拍摄图像的视差，恢复模型表面特征空间三维信息，由表面特征计算模型运动姿态。设计了一组有特定形状和严格尺寸的人工特征，具有识别正确率高、定位精确等特点。提供人工特征的设计方法。最后，分别给出旋转天平实验和风洞实验的实测数据，实测结果表明该方法测量准确，鲁棒性好，在立式风洞飞机模型尾旋运动测量的应用中十分有效。 |

| Abstract: |
| To measure the aircraft model attitude in the spin time, a method based on stereo vision is presented. We get the attitudes from a set of man-made signs on the surface of the model. From a pair of figures of the signs, their disparities are computed out. The design of the signs and the computation of the attitudes are presented in this paper. The man-made signs have good identifiability and the anchor points are accurate. Finally, the data of experiments to determine the aircraft model attitude are provided. Through the experiments, it can be concluded that the process of the computing is satisfactory, achieving high robustness. The measurement shows that the method discussed is useful for the experiments in the vertical wind tunnel. |
