The Application of Remote Sensing System for Micro UAV Based on CMOS Image Sensor
基于CMOS图像传感器的微型无人机遥感系统设计

A visible light remote sensing system based on CMOS image sensor for micro UAV was introduced.The remote sensing system substituted CMOS sensor for CCD.The drive timing module,data buffer and color interpolation module were realized on the hardware platform based FPGA.A C8051F MCU was the kernel controller of the system and the NAND FLASH memory was used as data storage.A RGB to PAL video signal encoder circuit was mentioned.The characteristic of the CMOS sensor was discussed.The color interpolation arithmetic used on PC was introduced.The weight of whole system was 20 g,and the power comsume was 2 W.And two remote sensing picture were presented which were obtained by this system from a micro UAV with 800 mm wingspan at 150 m altitude.
