Machine vision systems are incredibly complex. In even the simplest system, hardware and software work together to produce results. Although there are many vital components, one stands out: The lens.
Embedded machine vision technology can be produced at much lower costs and with far less power consumption than traditional devices. Ultimately, that means the current PC-based vision paradigm used in many sectors may give way to a more versatile, multifaceted approach.
Over the last two decades, industrial automation has undergone remarkable expansion. Barriers to entry are falling as enterprises large and small leverage the power of emerging technologies. Robots bring the promise of automation for more challenging, complex tasks. To achieve it, they rely on one thing more than any other: Machine vision.
Even with the most powerful technology, machine vision systems won’t work without the right lighting. A system’s lighting needs are highly variable, depending on the specific application and the operating environment. Engineers must be knowledgeable and flexible enough to optimize lighting based on the desired outcome and their knowledge of optics.
Not long ago, LED lights were a relative unknown in consumer circles. They were used only for very specific industrial and commercial purposes. However, LEDs have seen a great resurgence – powered, at first, by an embrace of their efficiency and low-heat performance. Now, they appear in cutting-edge machine vision systems with increasing regularity.
As science has advanced, it has called upon increasingly subtle tools for augmenting human vision. These days, machine vision systems can work together with more traditional tools to deepen the data that can be collected.
