Vision Algorithms Catch Defects in Screen Displays

Software based on NASA vision research is used in making laptop, cellphone, and TV displays. NASA has sent more than a few robotic missions into space, but it never loses sight of its goal to enable human exploration of the cosmos. A core component of planning for future manned missions is the Human Systems Integration Division, headquartered at Ames Research Center, that focuses on advancing our understanding of how people process information and interact with mechanical and electronic systems.

Researcher Spotlight: Atom­Thick Material Offers 2D Imaging Possibilities

Rice University scientists have developed a two-­dimensional, atom­-thick, light-­sensitive material called CIS, a single­-layer matrix of copper, indium, and selenium atoms. Sidong Lei, a graduate student, also built a prototype — a three-­pixel charge­-coupled device (CCD) sensor — to prove the material’s ability to capture an image. The optoelectronic memory material may be the basis for future flat imaging devices and two­-dimensional electronics.

Synthetic Vision Systems Improve Pilots' Situational Awareness

Visual Flight Rules (VFR) define a minimum of clear weather conditions under which a pilot can operate an aircraft using visual cues, such as the horizon and buildings. Under VFR, a pilot is expected to “see and avoid” obstacles and aircraft, and essentially only needs to see out of the window.

Tiny Camera Lets NASA Inspection Tool “See”

micro ScoutCam‘ 1.2 micro camera Medigus, Ltd. Omer, Israel 011 972 8646 6880 www.medigus.com NASA has incorporated the micro ScoutCam 1.2 into its Visual Inspection Poseable Invertebrate Robot (VIPIR) tool. VIPIR is a robotic, maneuverable, borescope inspection tool being tested as part of the Robotic Refueling Mission, an experiment on the International Space Station that has been demonstrating tools, technologies, and techniques for on-orbit satellite servicing since 2011.

Head-Worn Display Concepts for Ground Operations for Commercial Aircraft

This display enables a higher level of safety during ground operations, including taxiway navigation and situational awareness. Langley Research Center, Hampton, Virginia The Integrated Intelligent Flight Deck (IIFD) project, part of NASA’s Aviation Safety Program (AvSP), comprises a multi-disciplinary research effort to develop flight deck technologies that mitigate operator-, automation-, and environment-induced hazards. Toward this objective, the IIFD project is developing crew/vehicle interface technologies that reduce the propensity for pilot error, minimize the risks associated with pilot error, and proactively overcome aircraft safety barriers that would otherwise constrain the next full realization of the Next Generation Air Transportation System (NextGen). Part of this research effort involves the use of synthetic and enhanced vision systems and advanced display media as enabling crew-vehicle interface technologies to meet these safety challenges.

Flight Imagery Recorder Locator (FIRLo) and High-Temperature Radome

This technology is applicable to the commercial airline industry for locating “black boxes.” NASA’s Jet Propulsion Laboratory, Pasadena, California LDSD (Low Density Supersonic Decelerator) is a Mars EDL (entry, descent, and landing) Technology Development Project that launches three test vehicles out of the Pacific Missile Range Facility in Kauai. On the test vehicle, most mission science data can be recorded safely on land; however, high-speed and high-resolution imagery cannot be telemetered due to bandwidth constraints. Therefore, all information had to be recorded solely onboard the test vehicle; this unit is called the flight imagery recorder (FIR). A typical commercial airliner “black box” is only capable of recording on the order of gigabytes of data, whereas this work required on the order of terabytes (a few orders of magnitude larger).

Thermal Imaging’s Pocket-Sized Potential

Let’s say you’re a prospective buyer touring an older home that you suspect has some weatherization issues. What if you could verify your hunch by literally seeing cold air seeping under doors or cooling walls where insulation is missing? And what if you could do this on the spot using a smartphone?
