光电跟踪测量系统的动态成像分辨率分析及优化设计

摘要

Measurement precision and imaging quality of photoelectric measurement system were affected by kinematic image resolution of photoelectric measurement system.Kinematic resolution of imaging system of photoelectric measurement system is often limited in performance by photoelectric measurement system tracking precision.Analysis and experiment prove that working photoelectric measurement system has lower image resolution than static photoelectric measurement system.Objects with high movement frequency and low movement frequency opposed to exposures have different effect model on kinematic resolution of photoelectric measurement system.Static resolution and control system needs optimal design for some kinematic resolution.%光电跟踪测量系统的测量精度与成像质量受成像系统动态分辨率的影响.成像系统动态分辨率受光电跟踪测量系统跟踪精度的影响.分析与试验表明,光电跟踪测量系统的动态成像分辨率主要取决于静态分辨率和跟踪精度；工作过程中的光电跟踪测量系统的动态成像分辨率比光电跟踪测量系统的静态成像分辨率低；与传感器的积分时间相比,高频目标与低频目标对动态成像分辨率的影响模型不同；在传感器积分时间、目标的运动状态及对动态分辨率要求确定的条件下,可对静态成像分辨与控制系统进行优化设计.
