Image Enhancement and Corrosion Detection for UAV Visual Inspection of Pressure Vessels

Detection of Cracks and Corrosion for Automated Vessels Visual Inspection

Despite the efforts on reducing maritime accidents, they still occur and, from time to time, have catastrophic consequences both in personal, environmental and financial terms. Structural failure is the major cause of ships wreckages and, as such, Vessel Classification Societies impose extensive inspection schemes for assessing the structural integrity of vessels. The external and internal part...

Image Fusion for Automated Visual Inspection

ion levels for image fusion The fusion of an image series can take place on different abstraction levels (Fig. 1): • Within a data-level fusion (pixel-level fusion), the combination takes place at the level of the image data, i.e. the gray or RGB values. The precondition of a data fusion is that the images have been recorded with homogeneous sensors.

GPS Jamming Detection in UAV Navigation Using Visual Odometry and HOD Trajectory Descriptor

Auto-navigating of unmanned aerial vehicles (UAV) in the outdoor environment is performed by using the Global positioning system (GPS) receiver. The power of the GPS signal on the earth surface is very low. This can affect the performance of GPS receivers in the environments contaminated with the other source of radio frequency interference (RFI). GPS jamming and spoofing are the most serious a...

Visual novelty detection for autonomous inspection robots

Mobile robot applications that involve automated exploration and inspection of environments are often dependant on novelty detection, the ability to differentiate between common and uncommon perceptions. Because novelty can be anything that deviates from the normal context, we argue that in order to implement a novelty filter it is necessary to exploit the robot’s sensory data from the ground u...
