When designing an embedded vision system, choosing the right interface is a moment of truth. The interface plays a crucial role in determining its success because it is responsible for transmitting images from the camera to the processing system. Simply put, it is the physical connection layer that connects a camera to the processing platform for image processing. Two defining characteristics include proper throughput and suitable distance. The interface also influences the platform selection process since each one has its own interfacing limitations. In this blog, we hope to equip you to better understand how to choose the right interface for your embedded vision application.

The above-mentioned interfaces enable machine vision cameras to connect with host systems by using widely available USB and Ethernet standards. Choosing the right interface doesn’t just depend on the camera, but also target applications and computing platforms. When choosing the right interface for an embedded vision system, you should consider key factors such as bandwidth, cable length, cost, ease of implementation and use, power, and the physical connection required. At the end of the day, it is about choosing the best-fit solution that helps maximize your application’s ROI.

MIPI CSI-2 is one of the most common embedded vision interfaces. Even though it was developed for mobile devices, its 300 MB/s bandwidth makes it ideal for high-performance embedded vision systems. The maximum length of the MIPI CSI-2 cable is under 30cm, which solves application design challenges that involve a higher difference in distance between camera and processing systems. MIPI CSI-2 has four image data lanes that are each capable of 1.5 Gb/s. MIPI CSI-2 is faster than USB 3.0. It’s an efficient and reliable protocol that can handle video from 1080p to 8K and beyond. MIPI CSI-2 also uses fewer resources from the CPU because of multi-core processors. But in some cases, if a driver for the camera is not available, extra development costs can be incurred.

GMSL is a multigigabit, point-to-point connection that predominantly targets the automotive space. A GMSL interface can carry high-speed video, bidirectional control data, and power over a single coaxial cable. The GMSL cameras can be placed 15 meters away from the host processor through coaxial cable and still support less latency and a high frame rate. GMSL supports multithreading and aggregate protocols like Ethernet and DisplayPort over a single link.

Molecules each have their own unique motions and vibrations. The spectrum resulting from these motions are like fingerprints or barcodes, which we can utilize for identification. In the Grant group we use Raman Spectroscopy to identify small/low concentration molecules within a greater heterogenous mixture, such as cell cultures or tissue. Our goal is to make Raman Spectroscopy more easily accessible within a clinical environment for use in cancer diagnosis.

Embedded vision systems have brought to life new applications with never-before-seen capabilities. From life sciences and manufacturing and sports broadcasting, they form the backbone of critical functions across many industries – delivering innovation to meet evolving market expectations. The two basic criteria to assess the effectiveness of an embedded vision system are:

The Machine vision camera with a 20-megapixel Sony IMX183 sensor is ideal for Machine Vision applications, high resolution, and fast-rolling shutter.

The USB 3.0 interface has a much higher bandwidth than the USB 2.0 interface, up to 360 MB/s. For embedded vision systems, USB 3.0 can be easily integrated with the USB3 Vision Standard. The plug-and-play functionality of USB 3.0 drastically reduces development costs. It also enables embedded vision devices to swap out with ease – making it easy to replace a damaged camera. The USB has large connectors and fairly rigid cabling that may not be ideal for some compact embedded vision components. Most USB embedded vision cameras leverage the USB 3.1 Gen 1 interface to provide up to 5Gibt/s of image data bandwidth between the camera and the host system. USB 3.1 Gen 1 can simplify system design by supplying up to 4.5 W of power to an embedded vision camera.

The Ethernet interface, which is now mostly implemented as Gigabit-Ethernet (GigE), offers the broadest flexibility in terms of bandwidth, cable length, and multi-camera functionality. This interface can transfer data rates up to 120 mb/s with a maximum cable length of up to 100m and can be integrated into all image processing applications. GigE provides up to 1Gbit/s of image data bandwidth and is available with robust shielding.
