Frame grabbers are an important part of many high-end machine vision systems. They are essential in capturing high-resolution, high-quality photographs in a range of conditions.
If you’re searching for an industrial machine vision system, you’ll almost certainly require a frame grabber. But just what is a frame grabber? And what do frame grabbers do?
What exactly is a Frame Grabber?
A frame grabber is a machine vision component that collects individual still frames from a video stream, either analog or digital. Still frames are often taken digitally and displayed or transferred for analysis.
Frame grabbers are frequently connected to PC systems directly through conventional interfaces such as USB or Ethernet. Newer frame grabbers, among other things, can collect numerous inputs at once, manipulate pictures, and conduct real-time compression.
What Purpose Do Frame Grabbers Serve?
Frame grabbers are used for a number of applications, but one of the most common is to capture high-resolution photos that would otherwise be impossible to capture without a frame grabber.
Without the need of a frame grabber, smart cameras can collect digital still photos. When smart cameras were accessible, many people assumed that the frame grabber was doomed. However, smart cameras can only successfully collect still pictures for low-end applications.
Frame grabbers remain the preferred method for obtaining high-resolution digital still photographs. This is becoming increasingly true as camera megapixel resolution improves and the need for high-quality picture capturing grows.
Frame grabbers, in essence, capture still pictures where smart cameras cannot. They are employed in high-resolution, high-end applications to capture high-quality images.
Frame grabbers are critical components of machine vision systems used across the industrial sector. Many applications would be impossible to implement without the usage of frame grabbers.
