| 摘 要： | 微小型的低成本无人机具有起降场地限制小、运输方便、及成本相对低廉的特点,在小范围及分散的区域摄影测量工作中得到广泛应用,但低成本无人机在定位精度、续航航程、成像载荷选择等诸多方面需要进行取舍与妥协。因此需要提升低成本无人机的拍摄作业效率,构建一种低成本固定翼无人机,利用北斗／GPS组合定位增加高仰角卫星数,减少姿态角变化导致的定位精度下降;采用两个运动摄像头同步拍摄作为成像载荷;整套系统成本控制在一万以内。根据试验航程时间及试验后电池剩余电量的估算,机体作业飞行时间约1小时30 min,作业航程约70 km.

| Abstract: | Micro low-cost unmanned aerial vehicle (UAV) has the advantages of less restrictions for landing and takeoff, convenient transportation and relatively low cost. It is widely used in small scale and decentralized regional photogrammetry, but the design of low cost UAV have to trade offs and compromise between positioning accuracy, voyage, payload and many other aspects. Therefore, it is necessary to improve the efficiency of the low cost UAV photography, build a low cost fixed wing unmanned aerial vehicle, using Beidou／GPS combination positioning to increase the number of high elevation satellites to avoid the reduce of the positioning accuracy caused by the attitude changes; Two synchronized sport camera as the photography payload; the entire system cost control in less than ten thousand. According to the test flight time and the remaining power of the battery, this UAV have an operating time of about 1 hour and 30 minutes, and operating range about 70 km. |
