Consumer Electronics Inspection Put to the Test
Every year, smartphones, TVs, tablets, and computers get more capable in terms of screen resolution and processing power. This deluge pressures manufacturers to increase throughput. So they must reduce how long it takes on average to make one unit, an interval known as takt time.

Advancements in 3D Vision, Software Bolster Bin Picking
Numerous production processes are automated today that were inconceivable a few years ago. Of the many challenges to overcome, one of the primary ones is in vision-guided robotics, particularly in the area of bin picking, which involves the robotic selection and acquisition of objects at random from within a bin.

Advancements in Telecentric Technology
Generally, it is possible to distinguish between two main types of machine vision applications: inspection, which involves shape or color defect detection, presence/absence and position checking, and barcode reading; and gauging, which involves passing from traditional systems to noncontact optical measurement. It is in the latter that telecentric optics boast performance primacy when compared to standard entocentric, fixed focal length lenses.

Moth Flight Patterns Help Drones Navigate Complex Environments
Researchers from Boston University have captured data from moth flight patterns to improve drone navigation through complex environments. To understand how moths plan their route, the researchers, led by Ioannis Paschadilidis at BU and Thomas Daniel at the University of Washington, mounted eight hawk moths on metal rods connected to a torque meter. In front of each moth they projected a moving forest scene created from beams of light for the moths to navigate.

Using Microwave Metamaterials in Machine Learning Speeds Object Recognition

A new approach to object identification, developed by researchers at Duke University and the Institut de Physique de Nice (INPHYNI), enables joint learning of optimal measurement strategies and a matching processing algorithm, and uses inferred knowledge about task, scene, and measurement constraints to improve the accuracy of object recognition tasks while using a limited number of measurements.
