Computer vision systems get help from board-level systems

摘要

PCI Express (PCIe) has multiple gigabits/second of bandwidth and deterministic behavior, well suited for use with a computer vision system frame-grabber; it can capture high-resolution and high-frame-rate image streams.Traditional computer vision systems consist of a desktop PC with a plug-in PCI Express (PCIe)-based frame grabber card. The frame grabber captures images from attached camera streams and forwards them on the PCIe bus to the PC for image processing. Frame grabbers can be found in a variety of flavors for interfacing to analog and digital cameras, with popular digital camera types, such as CameraLink, IEEE 1394; and GigE Vision.
