DefectFinder is computer vision solution for high accuracy web inspection and surface inspection for textiles, nonwoven, paper...
The system comes with base configuration with 1 camera and software for standard detection like blobs, foreign objects, discontinuities. Base configuration includes management of three digital I/O from field and one line encoder.
Thanks to automatic recognition of batch cutting and download in conjunction with line encoder management, detections report uses real production batch coordinates

Custom detection and management software
On Line DefectFinder
Off Line Defect Manager
DefectFinder comes with precise defect detection and classification for Hole, Blob, Wave, Occlusion, Inclusion, Turn, Burns with back light technique.
Density, texture and front light colour analysis is also available.
We are ready to develop (also on site) customised detections for maximum accuracy and specificity
Custom I/O management
Additional I/O board is available for integration and management of signals from field how many as you want.
For example you might use a defect marker, a bar code batch reader/writer and so on.
Field Of View (FOV) and Cam Height(H) are related to resolution and minimum detection size.
Select module parameters for your needs and remember that you can connect a series of modules and use the system as if it's just one.

some detections on nonwoven product
“...we have reduced customer complaints close to zero as soon as we have installed DefectFinder!
… now we have faster control over production issues, we can get at to root cause and we can save more product batches.
...we are thinking to instal DefectFinder on all of ours lines.”
