Real-time image stabilization and mosaicking by using ground station CPU in UAV surveillance

A Novel Mosaic Quality Measurement Method for UAV Surveillance and Remote Sensing

“…On the other hand size and weight constraints of mini UAVs create several distortion effects such as severe vibrations and sudden movements. Several authors investigated image mosaics in order to address these issues and provide a natural way of real-time mapping (Morse et al 2008, Kumar et al 2001, Buyukyazi et al 2013. Specialized hardware can provide real-time processing speeds but it may not be suitable for installation in small size mini UAVs (Kumar et al 2001).…”

“…Constraining the camera orientation and UAV movements can restrict the flexibility required for better examination of the objects of interests (Morse et al 2008). Brief description of a novel hardware independent, real-time mosaicing and image stabilization system can be found at (Buyukyazi et al 2013) where real-time processing speeds were achieved by using Ground Control Station CPU and optimized algorithms adjusted for surveillance conditions.…”

“…In this paper a novel mosaic quality measurement approach developed for performance tests of the system described in (Buyukyazi et al 2013), by calculating amount of total drift resulting from following predetermined paths is presented. Instead of using artificially created images from a base image, method utilizes a set up consists of a 5 axis CNC for path following of the camera, printed hardcopy of high resolution aerial images for providing aerial scenery and ground truth information and camera used in mini UAVs for simulating operation of the actual system.…”

“…Main contribution of this paper is the novel Mosaic Quality Measurement method using 3D positioning and printed images. On the other hand, this method is developed as a part of larger project, and uses components of system described in (Buyukyazi et al 2013). System described in (Buyukyazi et al 2013) was tested by utilizing several state of art image registration methods.…”

System described in (Buyukyazi et al 2013) was tested by utilizing several state of art image registration methods. Also a brief overview of novel aerial mosaicing and image stabilization system, achieving real-time processing speeds by optimized algorithms, working on standard ground station without requiring any additional hardware in mini UAVs is provided.…”
