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).

Measuring Motion with Imaging Software

High-speed photography is as much of an engineering tool as an oscilloscope, spectrum analyzer, or logic analyzer. The photographic technique enables us to visualize and analyze motion, especially motion that is too fast for the human eye or conventional cameras to perceive.

3D Visualization Technologies: Seeing a World of Opportunity

Industries as diverse as architecture, engineering, construction, advertising, and medical have all incorporated an array of 3D visualization technologies into their design, development, and production processes. A rapidly expanding library of 3D modeling tools, 3D content, and 3D printing materials have made design more cost-effective and expedited the product-to-market process. But how exactly do 3D visualization technologies work? Taking a closer look at the science behind the innovation reveals a striking convergence in which state-of-the-art research processes meet a growing understanding of visual communication.

Precision Electronics and Laser Optics Expand Thermal Applications

Thermal imagers allow a user to see an object’s heat signature, and heat provides an entirely different set of performance data than the visible spectrum available to the naked eye. A fully radiometric camera will calculate a temperature value for every pixel seen on screen. The technician uses the thermal colors on screen to look for differences in temperature, between previous states or like components, without actually coming into direct contact with the device under test.

CAMERA TRENDS 2013: A Simpler Machine Vision

Today’s cameras are cheaper, smaller, and more capable than ever before. Without breaking the budget, a company manager who needs products inspected can buy a camera, quickly code in commands to recognize an object, bracket the device above a production line, and begin capturing images.

Flexible’ Machine Vision: Sensors, Lenses, and Software

Machine vision has become indispensable in today’s highly automated manufacturing environments, which rely on accurate in spec tion to ensure high product quality and high process efficiency. Applications for the technology span industry, and include everything from validation of printed barcodes and text on consumer product labeling, to assembly verification of printed circuit boards, to dimensional measurement of automotive parts. The demand for vision inspection only continues to grow with increasing throughput requirements and stringent quality standards that necessitate full inspection and render manual product inspection unfeasible.

Pixel-Scale Coated Sensors Bring Multispectral Imaging to New Users

The pixel-scale patterning of optical filters directly onto sensors has the potential to drastically simplify and scale down the cost of real-time multispectral imaging. Without moving parts, a more robust and compact system can be deployed into harsher environments than have been previously accessible for multispectral imagers.

Building an Immersive Training Platform for Infantry Soldiers

Developing an effective immersive training tool requires a fine balance of technology capabilities with human factors. Achieving a training goal to build squad leadership skills, squad-level communication, and mission rehearsal for an entire squadron brings together several components, including advanced body sensors that must translate physical movements, avatar actions, and high-resolution headmounted displays (HMDs) to immerse the user in the virtual world.
