What is GigE Vision?

These five different interface standards each have their own characteristics. Today, the focus is on introducing GigE Vision. It is created and promoted by the AIA (Automated Imaging Association). GigE Vision is a camera interface standard developed based on the Gigabit Ethernet communication protocol, suitable for industrial imaging applications, and capable of transmitting uncompressed video signals over a network.

GigE (Gigabit Ethernet) is characterized by high efficiency, high speed, and high performance. It is currently the fastest developing interface among industrial digital cameras and is also a universally applicable digital interface that can almost completely replace the camera interface of analog devices. It is now widely used in industries such as machine vision, education, government agencies, and industrial and mining enterprises.

Advantages of GigE Interface:

1. Good scalability, with the longest transmission data length that can be extended to 100m (without relay);
2. Fast transmission, with a bandwidth of 1Gbit, so a large amount of data can be transmitted in real-time;
3. Cost-effective, as it can use ordinary cables and standard connectors;
4. Easy to integrate, with low integration costs.

However, the GigE Vision interface also has some shortcomings. For example, the transmission of large amounts of image data can make the CPU overworked, which may lead to packet loss and latency.

Of course, for this issue, researchers have also found corresponding solutions. Here are two reference methods: The first is to use an image acquisition card with a built-in CPU (ARM) and FPGA, and transfer the image to the PC system in real-time through DMA (Direct Memory Access). This operation does not occupy the processor resources of the PC and ensures that there is no image or data loss during the image acquisition process.

The second is to choose jumbo frame settings, increase interrupt throttling rates, increase the value of receive descriptors, offload protocol operations, and image reassembly, etc. GigE industrial cameras can unify almost all industrial camera protocols in machine vision products, while also allowing other organizations to develop other compatible software and hardware based on it. Currently, many products can support the GigE Vision standard.
