Developers can choose between global shutter and rolling shutter read-outs depending on their application needs. ![]() This new industry standard achieves higher speeds and better image quality than its CCD counterparts due to its architecture, while also being significantly smaller in size. The most suitable image sensor for drones and embedded vision systems is a CMOS sensor. ![]() UAVs Place High Demands on Embedded Vision and Image Sensors The combination of the criteria, that being the size, weight, efficiency, image quality and processing to name a few, is a great challenge, even for embedded vision applications, and thus requires a careful selection and combination of the individual components. In both cases, the image quality must allow for an exact analysis and, for functional tasks, these images must be processed on-board, in real time. With the use of vision technology, functional drones are more intelligent and mostly autonomous. Functional applications, on the other hand, use these images from the vision system to navigate for collision avoidance or to initiate tracking-based follow-up actions. For pure image and video streams, where the drone does not derive any further actions based on the scene, are called non-functional applications. In addition, high power efficiency and low heat generation are important as there is usually only a limited power supply on board and any draw on this power supply affects the distances the drones can fly. It must have little impact on the flight performance. For drones, the vision system must be particularly small and lightweight. Frederik Schönebeck of FRAMOS spoke at the VDI conference on “Civil Drones in Industrial Use” and described the criteria for applications in mapping, object recognition and navigation as well as the relevance of artificial intelligence for drones.Ī vision system is a vision system and, in most cases, consists of an image sensor, a processor module, a lens mount and a lens. Each application has different requirements for the vision system and is dependent on the available space within the drone and the required image quality. From small sensor modules to artificial intelligence – there are different technologies and image processing algorithms to allows drones to see. ![]()
