一种基于光电经纬仪的数据预测跟踪技术

针对光电经纬仪上的跟踪器,提出了一种基于合成角数据的预测跟踪技术.利用目标的前几帧脱靶量和对应的经纬仪角度信息计算合成角,再以前几帧合成角数据为依据,利用线性动态模型推导出下一帧的合成角信息,计算出目标在图像中的位置,从而实现了对目标的预测跟踪.实验证明,该方法可以实现预测跟踪,减小处理区域,提高跟踪器的处理速度,有效地避免波门外虚假目标的干扰.

A Tracking Technique Based on Data Forecast of Photoelectric Theodolite

A forecast tracking technique based on complex angle about the tracker on the photoelectric theodolite is presented.In the course of tracking,the complex angle is computed based on the angle of theodolite and the offset of object.Then the next complex angle is forecasted according to the former complex angles and the linear dynamic model.Finally the object′s position is well and truly computed in the image.The result shows that,the method realizes the forecast tracking technique,minishes processing area,improves the processing speed of tracker,and effectively avoids the disturbance of the false object outside the region.
