Predicting patterns in machine vision can be problematic in the most stable times.
FREMONT, CA: Predicting patterns in machine vision can be difficult in the most stable times, but proper planning has become more challenging than ever before after 2020, a year of widespread instability. Many perspectives illustrate the industry's changing nature to assist machine vision practitioners in preparing for 2021 and beyond, amid this uncertainty. The predicted growth in 3D inspection, SWIR cameras, CoaXPress 2.0, embedded vision, and vision-guided robots are notable findings.
Inspection in 3D
The adoption of 3D imaging is motivated by the growing demand for higher quality inspection in various industrial verticals. In food, automotive, pharmaceutical, and semiconductor applications, a 3D device's ability to observe, inspect, and analyze objects with field depth gains significant momentum. In 2021, developments in 3D imaging algorithms are expected to enhance precision and speed in reconstructing inspected objects, useful in applications such as bin picking of heterogeneous items in various orientations and stacks.
Shortwave infrared (SWIR) line scan cameras are not new, but recent sensor technology advancements have made them more practical in applications such as silicon inspection, laser beam profiling, hyperspectral imaging, detecting chemicals and plastics, and medical imaging. The SWIR range—wavelengths between 900 and 2500 nm—detects features not immediately apparent in visible light. It is particularly useful in food inspection involving the detection of moisture.
V2.0 of CoaXPress
The new version of CoaXPress, CXP v2.0, has doubled the previous generation cable bandwidth to 10 Gbps (CXP-10) and 12.5 Gbps (CXP-12) per connection and is expected to become the de facto standard for interfaces with high-speed machine vision. System integrators will embrace CoaXPress v2.0, especially CXP-12, for high-speed inspection of semiconductors, consumer electronics, automotive parts, and much more in the coming year and beyond. Since these industries have long depended on coaxial cables, CXP v2.0 is also rapidly adopted in aerospace and intelligent traffic monitoring.
The combination of a board-level camera and a processing board that functions as a miniaturized computer is an embedded vision system. This "all-in-one" approach is an increasing alternative to PC-based image processing solutions, especially in lean applications where small size, low power consumption, and low costs are significant.
Vision Guided Robots
VGRs, which can perform tasks similar to human workers, often handle an aging population and increasing labor costs efficiently. For multiple tasks such as appearance inspection, dimension inspection, and counting and picking and placing, considerable momentum is behind vision-guided robots.
