【摘要】 薄膜充气可展开天线的性能受其面形加工的几何精度影响很大,由于天线本身材质的特点,在其面形测量的方法中,非接触式的视觉测量技术具有很大的优势。在对大尺寸薄膜充气可展开天线的面形进行视觉测量过程中,综合考虑几何约束、极线约束、站位约束、距离约束等多种约束条件,可以使系统匹配自动化的准确率提高到100%,测量相对精度达到5×10-4以上,满足天线测量要求,并且对于测量过程中的网络规划、提高解析计算可靠性等方面起到了关键作用。更多还原

【Abstract】 The performance of gossamer inflatable antenna relies on the geometric accuracy of the profile.Because of its flexible material,the traditional measurement technique can hardly meet the requirements.Therefore,the non-contact videogrammetry technique is appreciated.Considering various constraints, which play key roles in the videogrammetry for the profile of gossamer inflatable antenna,the correct rate of image matching reaches up to 100% and relative precision is higher than 5×10-4,which can meet the requirement of antenna measurement.Moreover,these constraints make great contributions to the network planning and system reliability.更多还原
