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.

Camera Link Selector

The CLM-602 Camera Link Multiplexer from Vivid Engineering (Shrewsbury, MA) interfaces two Camera Link cameras of any configuration (base, medium, full, 80-bit) to one frame grabber. The CLM-602 incorporates high-speed (85 MHz) interfaces. Multiple camera selection methods are provided, including rear-panel switch settings, Camera Link interface signals (serial or camera control), and an external RS-232 port. The selector is housed in a sturdy, compact aluminum enclosure.

Creating Better Thermal-Imaging Lens From Waste Sulfur

Sulfur left over from refining fossil fuels can be transformed into cheap, lightweight plastic lenses for infrared devices, including night-vision goggles, a University of Arizona-led international team has found. The team successfully took thermal images of a person through a piece of the new plastic. By contrast, taking a picture taken through the plastic often used for ordinary lenses does not show a person’s body heat.

Pedestrian Detection System Captures Body Heat

Researchers at Universidad Carlos III de Madrid (UC3M) have designed a new pedestrian detection system for cars that works in low-visibility conditions using infrared cameras to capture body heat. The new driving-aid system uses images captured by far infrared with two thermal cameras to identify the presence of individuals in their field of vision. The objective is to alert the driver to the presence of pedestrians in the path of the vehicle, and in the case of cars with automated systems, actually stop the vehicle.

3D-Printing Aerial Robot Mimics Tiny Bird

Scientists from Imperial College London have developed a 3D-printing Micro Aerial Vehicle (MAV) that mimics the way that swiftlets build their nests.The MAV is a quad-copter, with four blades that enable it to fly and hover. The vehicle, made from off-the-shelf components, carries in its underbelly two chemicals that create polyurethane foam when mixed, and a printing module to deliver the foam. The foam can then be used to build simple structures or repair components.The texture of the polymer exuded from the 3D printer can also be used to create ’grippers,‘ which stick onto and transport objects to different locations. The MAV could therefore pick up and remove bombs, or dispose of hazardous materials without exposing humans to danger. The next step for the team is to enable the vehicle to fly autonomously in any environment. The scientists plan to incorporate high-speed cameras and sensors on board the MAV, which will act like a satellite navigation system for tracking and controlling of the flight trajectory.SourceAlso: Learn more about NASA's Robonaut 2.
