摘　　要：视差对于望远系统的观察与瞄准都有着重大的影响,传统检测方法依赖检测精度较低的人眼判读,且无法定量给出视差调校量。通过对经纬仪检测视差的光路原型进行改进,研制了一种新型的双光路望远系统视差检测技术,通过两条光路分别接收望远系统物镜两侧的出射光线,依托图像判读技术检测望远系统的角视差,最终经过公式推导得到望远系统的线视差。根据物理模型建立图像判读十字分划中心偏移量与视差值之间的数学关系,该系统能够实现多种通光口径的望远系统视差检测,具有高效率、高精度、自动化等优点,检测精度可达11.9″。Parallax has a significant impact on the observation and aiming of a telescopic system.The traditional parallax detection methods mainly rely on the subjective interpretation of human eyes and the detection accuracy is low,and the parallax adjustment quantity cannot be given quantitatively.Based on the prototype improvement of parallax detection by theodolite,a new parallax detection method for the telescopic system with two optical paths is designed.It receives the outgoing rays on both sides of the objective lens of the telescopic system through two optical paths respectively,detects the angular parallax of the telescopic system by relying on image interpretation technology,and obtains the line parallax of the telescopic system through formula.The mathematical relationship between the offset of cross division center and the parallax value of image interpretation is established according to the physical model.The system can realize the parallax detection of a wide range of optical calibers with high efficiency,high precision,automation and other advantages,and the detection accuracy is as high as 11.9″.
