ON-BOARD THREE-AXIS VIDEO STABILIZATION SYSTEM USING DIRECT DRIVE TECHNOLOGY.

The evolution of technology in the field of unmanned aerial vehicles (UAVs) has led to the miniaturization of the equipment on board these aircraft. The most used equipment mounted on a UAV is still the video sensor, with the help of which the video image from the aerial vehicle can be processed for dedicated applications (facility inspection, surveying and mapping, operational oversight, traffic control, etc.). In this paper, we present the prototyping of a three-axis gimbal using the direct drive technology to replace the current two-axis gimbal payload equipping our Hirrus UAV. The results demonstrate notable improvements both mechanically, by excluding the gearing of the transmission belt (generating friction and elasticity in the system), and in terms of video resolution, maintaining quality especially at high zoom levels (over 5x).
