Smart network interface cards deliver efficient high-bandwidth GigE vision acquisition – Metrology and Quality News

Matrox Imaging has launched Matrox GevIQ, the industry’s first intelligent network interface card (NIC) offering generic GigE Vision acquisition offload at speeds of up to 25 Gigabit/s per port, with zero packet loss. With GigE Vision packet processing performed directly on board, Matrox GevIQ cards enable capture from one or more cameras without any loss of image data.

Machine vision applications requiring cameras with a 10+ GigE Vision interface can be challenging; they benefit from a high data transmission rate but suffer from increased demands on the host system, resulting in corrupted or lost image frames and increased processing latency. Matrox GevIQ offers a more versatile and broadly compatible alternative to proprietary 10+ GigE acquisition solutions. These cards pair easily with currently available GigE Vision cameras, delivering transmission rates up to dual 25 GbE with very little host CPU usage.

GigE Vision is a camera interface standard that provides fast image transfer over distances of up to 100m using standard copper and up to 5000m using standard fiber optic Ethernet cabling. The standard supports physical links from 1 to 25 Gigabit Ethernet (GbE). The use of 10 and 25 GbE by cameras is gaining popularity in the industry as they are ideal for vision applications requiring maximum imaging speed and resolution.

Matrox GevIQ cards partner with Matrox Imaging Library (MIL) X software and include both Matrox Gecho, a logging utility that logs events generated by the Matrox GevIQ device driver and saves them to a JSON or CSV file for view them in Google Perfetto, and Matrox Capture Works, a utility that allows users to quickly assess the performance and functionality of virtually any GigE Vision-enabled camera or 3D sensor.
