The development of machine vision interfaces highlights new technologies, such as PCIe and Thunderbolt, that improve performance and integration across various applications. Additionally, the upcoming GigE Vision 3.0 standard aims to enhance CPU utilization through the use of RDMA technology.
Many of today’s industrial software applications are designed to run natively on the Windows platform. Accessing and controlling external hardware devices with a Windows application is usually achieved by using a driver provided by the hardware supplier and activating hardware functions using an SDK.
Demand for accurate parts delivered on tight schedules is increasing. To keep pace, technology is continually advancing, enabling manufacturers to do more in the same amount of time.
Choosing the right interface for your machine vision application is a key decision in your camera selection process. The following sections provide an overview of the different types of cables and connectors available for machine vision applications along with associated pros and cons.
Understandably, designers of high-throughput, multi-camera machine vision systems have grown dissatisfied with those aging standards and have found a new champion, CoaXPress (CXP), a high-speed, point-to-point, serial communications interface that runs data over off-the-shelf 75Ω coaxial cables.
Smart cameras and vision sensors have been key tools for monitoring and controlling the manufacture and movement of products in industrial environments for many years.
Since its early days, machine vision has been primarily used to check the liquid level in a bottle, or verify if a packaging label is applied correctly.
