小型無人機是低成本的新型遙感平臺，要求裝載的遙感儀器體積小、重量輕、抗震性
好。PC/104+嵌入式計算機較好的滿足了此要求，并具備開發(fā)周期短的優(yōu)勢。研制成功無人機載小型多光譜成像儀(國內(nèi)首臺基于PC/104+嵌入式計算機的航空遙感儀器)和無人機載大 面陣CCD 相機系統(tǒng)。PC/104+嵌入式計算機在兩臺儀器中完成了曝光控制、圖像采集、傳輸、存儲、GPS 解碼計算、執(zhí)行遠程指令、狀態(tài)報告等功能。

Abstract: Small UAVs is an inexpensive new type of remote sensing platform. It requires remote sensing instruments to be compact, light, and shock resistant. The PC/104+ embedded computer satisfies the requirements, and has the advantage of short developing period. UAV-borne Compact Multi-spectral Imager (the first domestic PC/104+-based air-borne remote sensing instrument) and UAV-borne High-resolution CCD Camera System were developed. The PC/104+ embedded computers of two instruments performed varies functions, such as exposure controlling, image grabbing and storing, receiving and decoding of GPS data, executing of remote commands, status reporting, etc..
