New Drones Ensure Ideal Photographic Lighting Positions

Researchers at MIT and Cornell University will provide photographers with squadrons of small, light-equipped autonomous robots that automatically assume the right positions for photographic lighting. With the new system, the photographer indicates the direction from which the rim light should come, and the miniature helicopter flies to that side of the subject. The photographer then specifies the width of the rim as a percentage of its initial value, repeating that process until the desired effect is achieved.In the researchers' experiments, the robot helicopter was equipped with a continuous-light source, a photographic flash, and a laser rangefinder.The researchers tested their prototype in a motion-capture studio, which uses a bank of high-speed cameras to measure the position of specially designed light-reflecting tags with millimeter accuracy; several such tags were affixed to the helicopter.SourceAlso: Learn about Small-Object Detection via Fast Discrete Curvelet Transform.

Scientists Demonstrate Data Teleportation for Secure Communications

Teleportation, a long-standing staple in the world of science fiction, has become a reality for scientists at the U.S. Army Research Laboratory in terms of battlefield data and image processing. Army Research Laboratory quantum information principal investigator Ronald Meyers and team member Keith Deacon recently demonstrated information teleportation using entangled photons.

Synthetic Aperture Sonar Can Help Navy Hunt Sea Mines

Since World War II, sea mines have damaged or sunk four times more U.S. Navy ships than all other means of attack combined, according to a Navy report on mine warfare. New sonar research being performed by the Georgia Tech Research Institute (GTRI) could improve the Navy’s ability to find sea mines deep under water.

Imaging Space System Architectures Using a Granular Medium as a Primary Concentrator

Higher-resolution optics provide improved hyperspectral imaging for ocean and land monitoring, as well as exoplanet detection. NASA’s Jet Propulsion Laboratory, Pasadena, California Typically, the cost of a space observatory is driven by the size and mass of the primary aperture. Generally, a monolithic aperture is much heavier and complex to fabricate (hence, more costly) than an aperture of the same size but composed of much smaller units. Formation flying technology, as applied to swarm systems in space, is an emerging discipline.

Blurring the Boundaries: IP and Machine Vision Cameras Converge

In modern production facilities, users are more frequently combining two different strands of camera technology. Classic machine vision cameras manage inspection tasks and yield management, while network cameras (also called IP cameras) handle process monitoring and bringing production to a standstill when necessary.

Defining the Smart Camera

Smart cameras have been used in industrial applications for roughly two and a half decades, but advances in processor technologies have made the devices much more accessible and popular within the past 7 years, especially in areas such as machine vision and surveillance. However, when the term smart camera is mentioned, a wide variety of ideas still come to mind among individuals because there is no widespread agreement upon the definition of what a smart camera technically is. It is generally agreed upon that the basics of a smart camera include not only the image sensor, but also some type of processing chip: a CPU, DSP, FPGA, or other type of processing device (see Figure 1).

Indoor/Outdoor Cameras Improve School District’s Security

Located in Texarkana, Texas, Liberty-Eylau Independent School District (LEISD) has been serving communities since 1886. Today, the district has more than 2,700 K-12 students across six schools, including a high school, a middle-intermediate school, an elementary school, a primary school, a pre-K center, and a School of Success.

Line-Scan Camera

The 3DPIXA 3D line scan color camera from Chromasens (Burlington, MA) employs factory-calibrated stereo engineering. To output both color images and 3D altitude data in real time, the Chromasens 3DPIXA simultaneously captures two images of the same object. Height and shape are calculated using special algorithms running on the GPU.

Frame Grabbers

The PIXCI® EB1mini frame grabber from EPIX (Buffalo Grove, IL) captures from any base Camera Link device. The frame grabber includes trigger input, strobe output, shutter control, bit-packing capability, 64 bit memory addressing, and video rate sequence capture. The XCAP-Lite imaging program, provided with the PIXCI® EB1mini, provides control of image capture, as well as all board functions, through the Capture & Adjust Dialog.

X-Ray CCD Cameras

Andor Technology (Belfast, UK) has announced the iKon-M SY and Newton SY series of CCD cameras. The ‘standalone’ detectors offer -100°C deep cooling, optimized for the soft X-ray region. The 200-micron-thick Beryllium window blocks unwanted lower energies and visible wavelengths, with minimal beam hardening. The detectors are integrated and supported in a range of third-party software using Andor’s SDK, including MAT-Lab, LABView, and EPICs.
