Compact Vision System
A New Concept in Image Processing That Considers
It’s time to move beyond simply increasing the speed of image processing and start seriously shortening Machine cycle time. This is the concept
that gave birth to OMRON’s FH-series Vision System and its best-in-the-industry speed.
Manufacturing Machines are operated through the interaction of sensors, PLCs, servomotors, and other devices. Vision Systems measure positions
and perform inspections, and the results are used to control the operation of Machines. The demand for faster, more precise Vision System opera-
tion is the primary requirement. The FH-series Vision System provides higher speed and precision for Machine cycle time and is loaded with all of
the performance required to move Machines quickly and at high precision into a compact Controller for embedding into Machine. And even though
the Camera/communications interfaces, image processing algorithms, and other features of this complete image processing system are built into
one housing, the flexibility of a PC-based image processing system is also provided to help increase efficiency in the frequent reuse of Machine
designs and in design changes.

Realtime Image Transfer
High-resolution Cameras capture large amounts of data, which can make a
bottleneck out of the transfer speed time in addition to the image input time
bottleneck. An FH-series Controller provides a faster, multi-line image bus to
enable realtime transfer of large amounts of image data for high-resolution
Cameras or multiple Cameras. If high-precision measurements were sacrificed
due to speed, the FH Series returns your precision without increasing cycle time.
Camera resolution, driven by higher expectations for quality, continues to
increase. OMRON has greatly reduced the input time and image transfer
time to provide high-speed processing to match the speed of Machine
applications for high-resolution images. Even with more Cameras and
higher resolution, high-speed image input will contribute to increasing
throughput.

Perform Calculations for Multiple Cameras without Delay
Even when the measurement results of sequential operations are dependent on the speed of the independent action, parallel processing allows high
speed performance without any dwell time. The measurement results from four cores can be easily calculated on one Controller to achieve continuous
interaction without any special programming.

Frequently Waiting for Processing with a
Standard Vision Sensor
The lack of the ability for standard Vision Sensors to handle parallel
processing creates waiting time everywhere. If the Machine cycle
time cannot be increased, a Controller must be added for each
process to perform parallel processing, increasing costs.
