Raw data is commonly presented in graphical form in published literature. Often authors may be in need to source data from such publications. The raw research data is normally not available to fellow researchers due to non availability of data itself or lack of interest of the author to share the data. Presently many software tools are available for extracting the data from the graphs. But the user...
A collision avoidance system is an automobile safety system designed to reduce the severity of an accident. It uses a combination of radar, laser and camera to detect the obstacles and avoid an imminent crash. Being relatively cheap, and capable of giving depth information stereo camera pair alone can be used for obstacle detection. Prime step in obstacle detection by stereo camera system is the generation...
Generally, an aircraft contains three rotational motions: pitch, yaw and roll. The roll motion is controlled by ailerons on either side of the aircraft is considered as the plant. In this work a fuzzy-PID controller has been designed and implemented in ASIC in order to control roll motion. First step is to identify a suitable controller which is followed by modeling of the controller and lastly by...
Over the past few years Micro Air Vehicle has gained prominence due to its widespread applications in the field of military and civilian applications. Images captured by onboard cameras on a MAV need to be processed in real time and for this purpose segmentation algorithm is used. On board processing of images is a major challenging task as it involves deciphering images and performing the required...
Vision-based autonomous following of geographical tracks such as rivers and pipelines is a potential solution in applications denied by GPS. Vision-based track-following algorithms require two parameters to determine the aircraft heading namely, orientation of the track and the displacement of the track from an appropriate reference. Track visibility is a prime factor for effective mission. Despite...
