摘要
涉及的摄远测量系统,是结合卡塞格林系统设计,给光学系统引入像差,产生畸变,光学畸变直接影响到测量精度,因此,首先应对系统光学畸变校正。研究基于卡塞格林系统设计的不同光谱范围,不共光轴及不同分辨率的摄远光学系统的畸变校正。现有光学畸变校正仅适用于近距离光学系统校正。考虑本光学系统特点,提出一种适用于本光学系统的畸变校正方法。通过搭建等效测量系统,应用畸变校正方法校正系统光学畸变,并验证畸变校正方法的正确性。实验表明:该方法重投影误差小于0.4像素,研究的校正方法提高了异光谱卡氏非共轴摄远光学系统的测量精度。
The telephoto measurement system of this paper is combined with the design of Cassegrain system,aberrations are introduced to the optical system and distortion is generated. The measurement accuracy is directly affected by the optical distortion. Therefore, the system optical distortion correction must be performed firstly. In this paper, the distortion correction of telephoto optics is studied based on different wavelength ranges designed by Cassegrain system, Non-coaxial and different resolution. The existing optical distortion correction is only applicable to close-range optical system correction. Considering the characteristics of this optical system,a distortion correction method suitable for this optical system is proposed. By constructing an equivalent measurement system,the distortion correction method is applied to correct the optical distortion of the system;and the correctness of the distortion correction model is verified. Experiments show that the reprojection error of this method is less than 0.4 pixels. The measurement accuracy of Different Spectra Cassegrain Non-coaxial Telephoto Optical System is improved by this correction method.
