Aravis uses libusb to implement the USB3 Vision protocol.Significant application logic outside of this kernel module is needed to incorporate GenICam and be fully compatible with the USB3 Vision specification) Linux kernel driver (NOTE: Basic register access and image streaming only.A complete list of companies offering products complying with this standard is available here: Companies that license USB3 Vision.These can include lighting synchronization and separate motor controls for optical focusing elements. For many real devices, the vendors provide alternate methods such as I2C to access the full set of parameters that a specific device may support. This contrasts with Camera Serial Interface the Camera Command Set (CCS) is part of that standard for controlling camera parameters. This standard and GigE Vision are examples of wire protocols which pair with the GenICam standard. The GenICam standard is independent of the transfer protocol. The GenICam standard has a Standard Feature Naming Convention so that vendor agnostic software can be created. The camera specific registers can be queried via a XML schema file which is part of the GenICam standard. The later register types are diverse across cameras. ![]() Register Access includes mandatory USB3 vision registers as well as camera specific registers which may control parameters such as shutter speed or integration time, gamma correction, white balance, etc. As the standard is defined at a protocol layer, the software vendor providing the driver may be a different entity than the company designing the camera. The standard defines a specific USB Class ID (Class 0圎F, Subclass 0x05) for identifying the device. Additionally, it defines locking connectors that modify the standard USB connectors with additional screw-locks for industrial purposes. Some of the benefits of this standard include simple plug and play usability, power over the cable, and high bandwidth. The standard is built upon many of the same pieces as GigE Vision, being based on GenICam, but utilizes USB ports instead of Ethernet. The standard itself for reference or evaluation may be requested free of charge. As of late 2019, there are 42 companies that license this standard. The standard is hosted by the AIA and developing a product implementing this standard must pass compliance tests and be licensed. As of October 2019, version 1.1 is the latest version of the standard. It is recognized as one of the fastest growing machine vision camera standards. It describes a specification on top of the USB standard, with a particular focus on supporting high-performance cameras based on USB 3.0. USB3 Vision is an interface standard introduced in 2013 for industrial cameras.
