摘要
研究了舰载光电跟踪设备的稳定跟踪技术,提出了一种基于机动平台预测跟踪方案.利用坐标转换将前几帧合成角数据转换到大地坐标系,并利用合成角轨迹预测当前帧合成角数据,然后将预测结果转换到甲板坐标系,实现了机动平台的稳定跟踪;给出了该预测结果与在甲板坐标系直接预测结果的比对,证明该预测技术更为精确,有利于实现机动平台的稳定跟踪.
Aim at the tracker on the photoelectric transit, which is placed on the ship. A forecast tracking technique based on mobile flat is presented. The former complex angle is transform from board coordinate to earth coordinate. The next complex angle is forecasted in earth coordinate; final, the forecast result is transform to the board coordinate. The stable tracking technique based on mobile flat is realized. This forecast result is compared with direct forecast in board coordinate, which fully prove that this forecast technique is more accurate and propitious to realize stable tracking on mobile flat.
