摘要

离焦造成的成像模糊, 严重影响光测设备的跟踪性能与精度。根据光测设备传感器多、跟踪精度高等特点, 提出了在单台设备上基于双目视差测距的实时调焦方案。建立了不同焦距双目视差测距模型并进行了误差分析, 介绍了光学系统调焦原理, 结合光测设备的具体参数, 进行了测距调焦数值仿真。结果表明, 像素尺寸越小, 基线、焦距的乘积越大的传感器, 其测距误差越小。以中波红外对目标进行中心跟踪, 以电视脱靶方式进行测距调焦, 能够很好地满足设备的实时调焦需求。仿真结果表明, 双目视差测距实时调焦在单台光测设备上的应用是可行的。

Abstract

The imaging blurring caused by defocus seriously affects the tracking performance and accuracy of optical measurement equipment. According to the characteristics of multi-sensor and high tracking accuracy of optical measuring equipment, a real-time focusing scheme based on binocular parallax ranging on a single device was proposed. In this paper, the binocular parallax ranging models with different focal length were established and the error analysis was carried out. The focusing principles of optical system were introduced.The numerical simulation of auto-focus method based on ranging was carried out in combination with specific parameters of the optical measuring equipment. The results show that smaller pixel size and larger product of baseline and focal length result in smaller ranging error. Making target tracking centrally with the middle infrared sensor and ranging with TV off-target can satisfy the real-time focusing requirement of the equipment.
