Abstract: The outbreak of COVID-19 epidemic situation in 2020 puts forward higher requirements for contactless distribution. Based on the characteristics of small and agile of the UAV, this paper designs a type of delivery UAV can be applied in residential areas. The system extends around TM4C124GH6PM and its extension, carries the laser radar, TOFSense laser ranging sensor, airborne computer raspberry pie, OPENMV and other modules, and uses PID adjustment and image processing algorithm, analyzes the attitude and location information of UAV, automatically recognizes the material sample characteristics. It realizes automatic delivery function, reduces the risk of epidemic situation spread, and it has strong versatility and broad prospects for development.
Keywords: delivery UAV; OpenMV; image recognition

2020年新冠疫情爆发,社区居民的物资配送问题面临巨大挑战。居民下楼自取或相关工作人员上门配送等传统配送方式,均会增加交叉感染的风险,且将使社区工作人员的工作量剧增,降低配送效率,造成人员不足等问题。送货无人机可以解决这一问题,首先,相较于智能小车,无人机在“二维”基础上提升到“三维”,可以直接将物资送至窗户外,使居民足不出户就可以取到物资,真正实现了“无接触配送”,降低传染风险。而且无人机可以提升工作效率,减少了一些重复且机械性的工作,如工作人员上下楼,降低劳动成本。除此以外,当不同种类的物资需配送到不同指定居民时,可以在送货无人机上搭载视觉模块,识别物资的特征信息,如二维码、颜色和形状,从而实现精准自动配送,减少了因人工疏忽而造成的重复劳动,进一步提高工作效率。……
