| 摘 要： | 微波天线的工作面的加工精度直接影响其工作性能,因此,对加工后的工作面进行高精度的面形测量是必要的.一种新的基于距离相对约束的视觉测量方法被用于微波天线面形的高精度测量,测量程序可分为两步:直接线性变换求初值和基于距离约束的最优化解算,解算过程中完成了透镜畸变的校正,其相对精度可达1/2,000,并用最小二乘法拟合了微波天线的面形.

| Abstract: | The performance of microwave antenna is susceptible to its machining accuracy. Therefore, it is necessary to precisely measure its profile. A new videogrammetric method for microwave antenna based on the distance constraint is presented. There are two steps in the measurement procedure: direct linear transformation and nonlinear optimization based on the distance constraint. The measurement error resulted from lens distortion can be corrected. The relative accuracy of 1 part in 2000 can be achieved during measurement. Finally, the profile of the microwave antenna is obtained using the least squares fitting method. |
