In recent years, the rapid development of light remote sensing platforms and remote sensing load has brought unprecedented opportunities for remote sensing of Unmanned Aerial Vehicle (UAV). In order to meet the high requirements of remote sensing applications such as precision agriculture, forestry monitoring and environmental protection etc., we designed and integrated a UAV-based hyperspectral imaging system. This paper briefly introduced the composition of the system, and discussed the geometric processing of hyperspectral data. A Spline function mosaic method based on Sparse Bundle Adjustment (SSBA) is proposed for rapid flight strip images stitching. Hyperspectral data is collected by the UAV imaging system, and the stitching results indicate that our method can obtain better results than SURF.
