Deep Learning-Based Industrial Image Analysis
January 1, 2020
"VisionPro ViDi from Cognex is the first deep learning-based image analysis software designed specifically for factory automation," said a company spokesperson. "It is a field-tested, optimized and reliable software solution based on a state-of-the-art set of algorithms in Machine Learning. Combining artificial intelligence (AI) with VisionPro and Cognex Designer software, VisionPro ViDi is designed to solve complex applications that are too difficult to program and maintain using traditional machine vision systems."
ViDi deep learning technology consists of four different tools:
- Feature localization and identification-ViDi Blue-Locate finds complex features and objects by learning from annotated images. Self-learning algorithms locate parts, count translucent glass medical vials on a tray and perform assembly verification checks on kits and packages. To train the Blue-Locate tool, all the user needs to provide are images where the targeted features are marked.
- Segmentation and defect detection-ViDi Red-Analyze is used to detect anomalies and aesthetic defects. Be it scratches on a decorated surface, or incomplete or improper assemblies, the red tool can identify all of these and many more problems simply by learning the normal appearance of an object, including its significant but tolerable variations. The red tool is also used to segment specific regions such as defects or other areas of interest, and can identify all of these regions of interest simply by learning the varying appearance of the targeted zone.
- Object and scene classification-ViDi Green-Classify is used to classify an object or a complete scene. Be it the identification of products based on their packaging, the classification of welding seams or the separation of acceptable or inacceptable defects, the green tool learns to separate different classes based on a collection of labelled images. To train the Green-Classify tool, all the user needs to provide are images assigned to and labelled in accordance with the different classes.
- Reads text and characters-ViDi Blue-Read deciphers badly deformed, skewed and poorly etched codes using optical character recognition (OCR). The pre-trained font library reads most text out of the box and minimizes training steps for fast, easy implementation. This robust tool can be retrained to adjust to specific OCR application requirements-no vision expertise required.
