研究目的
To review recent developments in UAV-borne hyperspectral remote sensing, including platforms, sensors, system integration, data observation, and preprocessing, and to discuss applications and future trends.
研究成果
UAV-borne HRS systems offer an economical, safe, flexible, and high-spatial-resolution observation solution, making them suitable for various applications in agriculture, forestry, geology, and environmental monitoring. Future trends include multisensor integrated systems, new hyperspectral sensors, hybrid UAV platforms, and multiscale analysis.
研究不足
The main limitations include the limited endurance and swath width of UAVs, making them unsuitable for very-large-scale aerial surveying. Additionally, the accuracy of geometric correction depends on the precision of the GNSS/IMU module.
