Extract type plates, identification plates or license plates

This OCR and AI tutrial will guide you to create an AI to extract type plates, identification plates or similar unstructured documents. If you are new to Konfuzio please watch the Quickstart Tutorial first.

Create a Project to OCR type plates, identification plates or license plates

Create Project to extract data

Create a Label to extract the chassis number

As an example we create the chassis number label and assign it to the Category “Type plate”. You could add as much different Labels as you want and need.

Test your AI to extract type plates

Upload new documents. You will now see suggestions. Revise those suggestions and add this document as testing Document.

Upload more type plates and add those documents as training documents

Iterate of the previous steps and add as many documents you need to reach your accuracy goal.

Optional: You can expand to extract other documents

You an even go beyond and find other documents that contain the ident number and extract those.

As you see the AI ad-hoc provides suggestions. However, you might want to separate those types of documents in different categories. This will help you to train one specialized AI for every type of document. This will ensure a high level of accuracy for type plates, identification plates and license plates.
