摘要： Method and system for passively detecting wires from a mobile transport system is provided. The method includes, pre-processing a digital image taken from a digital camera of the transport system, wherein the pre-processing is performed by a pre-processing module to reduce non-wire like clutter from the digital image; identifying pixels that can be classified as wire like by using a segment finder module on the digital image that has been pre-processed by the pre-processing module; and linking the identified pixels to determine if a wire like structure is present, wherein a linker module links the pixels that can be classified as wire like, to generate a wire overlay.

摘要： Apparatus and methods for target detection in hyperspectral images are disclosed. In one embodiment, a method of detecting a target in a hyperspectral image includes spectrally unmixing the hyperspectral image into segments, each segment having at least one of similar spectral composition, similar textural composition, and similar variation, and spectrally unmixing at least one of the segments. The method further includes creating a clutter rejection filter for at least one segment, filtering at least one segment, and calculating target abundances in at least one segment. In alternate embodiments, channel reduction can be performed on the hyperspectral image and also on at least one segment. In further embodiments, data associated with the location of possible targets in the segments may be compiled. In yet another embodiment, this data may be compressed by cross referencing data from all segments and eliminating redundancies.

摘要： A hardware system for passively detecting wires from a mobile transportation system is provided. The hardware system includes a main processor in the hardware system that uses plural commands to manage a preprocessor module and a linker module, wherein the pre-processing module pre-processes a digital image taken from a digital camera of the transport system and reduces non-wire like clutter from the digital image and identifies pixels that can be classified as wire like; and the linker module links the identified pixels to determine if a wire like structure is present and a binary output from the linker module is sent to an output select module that allows a user to select a video output.

摘要： A collision sense and avoidance system and method and an aircraft, such as an Unmanned Air Vehicle (UAV) and/or Remotely Piloted Vehicle (RPV), including the collision sense and avoidance system. The collision sense and avoidance system includes an image interrogator identifies potential collision threats to the aircraft and provides maneuvers to avoid any identified threat. Motion sensors (e.g., imaging and/or infrared sensors) provide image frames of the surroundings to a clutter suppression and target detection unit that detects local targets moving in the frames. A Line Of Sight (LOS), multi-target tracking unit, tracks detected local targets and maintains a track history in LOS coordinates for each detected local target. A threat assessment unit determines whether any tracked local target poses a collision threat. An avoidance maneuver unit provides flight control and guidance with a maneuver to avoid any identified said collision threat.
