The invention belongs to the technical field of three-dimensional scanner assistance, and discloses an unmanned aerial vehicle carried aerial three-dimensional scanner which comprises an unmanned aerial vehicle and a three-dimensional scanner, a support is installed at the bottom of the unmanned aerial vehicle, a fixing block is fixedly installed on the inner side face of the support, and a flow dividing block is fixedly installed in the fixing block; an air inlet groove and an air outlet groove are sequentially formed in the front side and the rear side of the fixing block, and a first air channel and a second air channel are sequentially formed in the front side and the rear side of the interior of the fixing block. Airflow entering the inner cavity of the fixing block is divided into two parts, namely a1 and a2 through the flow dividing block, obviously, the path of a1 is longer than a2, so that the flow speed of a1 is larger than that of a2, the pressure intensity of the front face of the flow dividing block is smaller than that of the back face of the flow dividing block, the whole fixing block has forward pressure, and the pressure acts on the whole unmanned aerial vehicle and the whole three-dimensional scanner forwards; therefore, the resistance of the unmanned aerial vehicle during forward flight is effectively reduced, and the flight power consumption of the unmanned aerial vehicle is effectively reduced.
本发明属于三维扫描仪辅助技术领域,且公开了一种无人机搭载的空中三维扫描仪,包括无人机和三维扫描仪,所述无人机的底部安装有支架,所述支架的内侧面固定安装有固定块,所述固定块的内部固定安装有分流块,所述固定块的前后两侧依次开设有进风槽和出风槽,所述固定块内部的前后两侧依次开设有一号风道和二号风道。本发明通过设置有分流块将进入固定块内腔的气流一分为二:a1、a2,很明显a1的路径长于a2,因此a1的流速大于a2的流速,所以,分流块正面的压强小于背面的压强,使固定块整体具有向前的压力,此压力向前作用于无人机和三维扫描仪整体,从而有效降低了无人机在向前飞行时的阻力,有效降低了无人机的飞行电力消耗。
