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。
The measurement accuracy and imaging quality of photoelectric tracking system are affected by the dynamic resolution of the imaging system. The dynamic resolution of the imaging system is affected by the tracking accuracy of the photoelectric tracking system. Analysis and experiment show that the dynamic imaging resolution of electro-optical tracking and measuring system mainly depends on the static resolution and the tracking accuracy. The dynamic imaging resolution of photoelectric tracking and measuring system during operation is lower than the static imaging resolution of photoelectric tracking and measuring system. Compared with the integral time of the sensor, the influence models of the high frequency target and the low frequency target on the dynamic imaging resolution are different. Under the conditions of the sensor integration time, the motion state of the target and the requirement of the dynamic resolution, the static imaging resolution and control System optimization design.
