Vision System

FH Series

AI-based automated visual inspection

AI captures defects with human-like sensitivity

Defect detection tasks that rely on human sensibility are a challenge to automate. Fortunately, powerful new AI technology can match the skills and capabilities of experienced inspectors.

FH Series Features 1

AI reproduces human expertise through learned criteria

AI Scratch Detect Filter *1

The AI Scratch Defect Filter learns by means of images in which human inspectors noticed defects. Whereas previous inspection methods found the unexpected size, shape or color of a particular defect to be a barrier to automation, AI successfully extracts abnormalities by judging their features without definition. The learned data facilitates defect detection on processed surfaces and other uneven backgrounds that previously posed an insurmountable challenge.

FH Series Features 3

*1. The FH-UMAI1 Scratch Detect AI Software Installer is required to use AI Scratch Detect Filter.

Automatic detection of various defects without definition and learning

Regardless of material type, color, or size, defects can be extracted reliably without previously required definition and adjustment.

FH Series Features 5

AI identifies good products as well as experienced inspectors

Sensory inspection requires a certain tolerance for variations that don't pass a certain threshold.
Determining what variations are acceptable is a key capability of expert inspectors and poses a challenge for automated inspection systems.

FH Series Features 6

AI reduces overdetection

AI Fine Matching

AI Fine Matching identifies a future that is not included in good products as a defect.
AI learns images of good products with variations, and generates an AI model.
Every time an inspection is carried out, AI reconstructs a model that is presumed to be a good product.
AI extracts a difference between the reconstructed good product image and a captured image to identify a defect, reducing overdetection.

FH Series Features 8

AI makes it easy to avoid overdetection [PATENT PENDING]*1

Three quick steps on the settings screen guide the user through the process of creating the good product model with the minimum number of images.

No special environment is required

With the FH Series, there's no need for high-end hardware or specialized engineers who can configure the system to suit your needs. Our general-purpose vision system makes it easier than ever to introduce AI into production sites.

Vision controller with AI functionality

Artificial intelligence has traditionally required a high-end environment, but our lightweight creative solution comes in the form of user-friendly processing items that have been integrated into our popular FH Series hardware.

*1. The FH-5550 Controller is compared with the FH-3050 Controller.

High-resolution cameras

We offer a range of cameras that can capture high-resolution images suitable for sensory inspection at high speeds.

FH Series Features 14

Ultra-high-speed sensing technology in a compact design

There was a trade-off between high-resolution image capture like the human eye and inspection processing speed. We use new CMOS image elements and dual transfer technology to capture high-resolution images while transferring images at high speeds. This facilitates applications that previously required multiple cameras or a mechanism to move a camera.

MDMC light with flexible lighting patterns

This light can be adjusted to defects by combining the illumination colors and angles like humans do.
Even if new objects or inspection items are added after installation, there is no need to add or change the light—just change the illumination pattern.
The illumination patterns can be registered as settings, facilitating duplicating production lines.

FH Series Features 24

Parallel processing for different inspections

Multi-Line Random-Trigger inspects at up to four different timings

A single controller can perform inspections at different points at different timings.
Controllers installed for each process can be integrated into one, reducing initial costs and saving space.

The FH Series can associate a unique ID with the inspection image and result, and then output them to the host device.
You can immediately find required inspection images and quickly identify causes of fails.

FH Series Features 43

High-speed image storage

The amount of inspection image data required for defect cause analysis can be so large that conventional controllers are unable to store it given their storage time and capacity constraints.
The high-speed, large-capacity controller has USB 3.0 ports and the improved algorithm to compress image data at high speeds, enabling all images to be stored to meet increasing needs in quality control.
