摘要
为提高无人机的定位精度、缩减影像数据后处理时间,提出基于GPS/IMU紧耦合定位技术。应用POS辅助光束法平差技术和CUDA技术实现影像快速拼接。实验证明该方案能够大幅提高无人机巡查效率,在辅助城市巡查管理中取得了显著成效。
In order to improve the positioning precision of unmanned aerial vehicle and reduce the post processing time of image data,the high precision positioning of UAV based on GPS/IMU tight coupling positioning technology is proposed.POS assisted beam adjustment and CUDA technology are used to achieve rapid image mosaic. Experiments show that the scheme can greatly improve the efficiency of UAV patrol,and has achieved remarkable results in the auxiliary city patrol management.
