研究了无控制点数据、仅利用无人机系统记录的辅助数据进行无人机图像快速拼接和校正的方法。提出了无人机图像分块后快速自动拼接和基于辅助数据伪中心点的无人机图像校正两种算法。应用SIFT算法进行无人机图像拼接时，精度很高，但效率很低。图像分块后基于SIFT算法大大提高了拼接效率。结果表明，采用辅助数据伪中心点时，矫正精度非常高，且无视觉错位。
The methods of unmanned aerial vehicles images splicing rapidly and rectifying without control points data, only using auxiliary data recorded by unmanned aerial vehicle (UAV) system, were researched. Two algorithms were proposed, including UAV images auto- splicing rapidly after image blocking and UAV images rectifying based on pseudo center points of auxiliary data. When SIFT algorithm for UAV images splicing is applied, the accuracy is very high, but the efficiency is very low. The splicing efficiency is improved greatly based on SIFT algorithm after image blocking. The results show that rectifying accuracy is very high and has no visual dislocation when pseudo center points of auxiliary data is applied.
