Development of double median filter for optical navigation problems

Processing of the images received from moving objects which including unmanned aerial vehicles (UAVs) was considered. To increase the speed and ensuring high-quality filtering without additional distortions while processing the double median filter was designed. Interaction between VHDL design environment and FPGA tools during double median filter development was shown. Models of ensuring quality of definition of geometrical features after a filtration during recognition of routes on the image at optical navigation are presented.
