无人机低空遥感系统传感器选型研究

Research on Sensor Selection for UAV Low-Altitude Remote Sensing System

针对无人机低空遥感系统所搭载的传感器选型问题提出了相机重量、传感器尺寸、视场角、有效像素等参考因素;同时,通过无人机航摄项目模拟对索尼A900、佳能5D-Ⅱ、佳能5D-Ⅲ及尼康D800四款备选传感器的航空摄影测量效率进行评估;推荐首选尼康D800作为搭建无人机低空遥感系统的传感器。

To solve the sensor selection for UAV low-ahitude remote sensing system, proposed the reference factors such as camera weight, sensor size, field angle and effective pixels. In the meantime, the UAV aerial photography project simulation was used to evaluate the efficiency of aerial photogrammetry for the four alternative sensors ： Sony A900, Canon 5D- II,Canon 5D-III and Nikon D800. Nikon D800 was recommended as preferred sensor while build UAV low-alti- tude remote sensing system.
