Backlit symbol inspection requires photometric capabilities to measure brightness, and color and computer vision capabilities to evaluate shape.MATT SCHOLZ AND ANNE CORNING, RADIANT VISION SYSTEMSIn the automotive industry, safety is a paramount consideration when designing and manufacturing vehicles. Even as technology, consumer expectations, and market forces have evolved over the decades, safety is still at the forefront. Critical to the safety of any vehicle are its lighted components. Illuminated gauges, buttons, and icons communicate vital information to the driver and facilitate safe vehicle operation — in any ambient light or environmental condition (Figure 1). These indicators must be clear, legible, and instantly recognizable whether the vehicle is bathed in bright...Read full articleRelated content from Photonics MediaARTICLESNavigating the Options for 3D ImagingWhile 3D imaging in machine vision has been applied in key use cases for many years, use of the technology has recently grown and expanded, making it increasingly common in a wider range of...Vision Spectra Summer 2022 IssueEmbedded Vision Is Set for Application on a Massive ScaleCompact, efficient, and highly application specific, embedded vision technology increasingly offers performance and price points that would have been impossible to achieve only a few years ago.
