摘要

根据现阶段光电瞄具的靶场测试需求,针对目前传统视差检测方法存在的无定量、大误差、低效率等缺点,提出了一种基于类正弦测微法的视差检测方法,该方法可实现光电瞄具视差的快速定量测试。采取传统摆头法的快速观测原理,利用类正弦测微法实现定量数据获取,构建出一台具有类正弦微动细分机构的改进型视差检测装置。选取了三类典型的光电瞄具样品,针对4种视差测试方法进行详细的测试效果比对实验。结果表明,基于类正弦测微法的视差检测方法及装置不仅能够保证0.01′的测试精度,而且能够满足光电瞄具靶场测试中效率高、精度高的需求,测试效果优于其他传统视差检测方法。

Abstract

According to the requirement of target range test of photoelectric sights at present stage, aiming at the defects of non-quantitative, large error and low efficiency of traditional parallax detection methods, a parallax detection method based on sine-like micrometric method is proposed. Quick and quantitative test of photoelectric sight parallax can be realized by the proposed method. Taking the fast-observing principle of the traditional pendulum method, sine-like micrometric method is used to realize the quantitative data acquisition, and an improved parallax detecting device with sine-like micromotion subdivision mechanism is constructed. Three kinds of typical optoelectronic sights samples are selected, and the test effect comparison experiments of four kinds of parallax test methods are conducted in detail. The results show that the parallax detection method and device based on sine-like micrometric method can not only ensure the testing accuracy of 0.01′,but also meet the requirement of high efficiency and high precision in the target range test of photoelectric sights, and the test result is superior to other traditional parallax detection methods.
