Ocr Extraction

OCR Extraction (Google Vision / Document AI)

The robomotion googlevision and robomotion googledocumentai CLIs extract text from images and scanned documents using Google Cloud Vision OCR and Document AI. They support image text detection, document parsing, and structured content extraction.

When to use

• Extract text from images using Google Vision OCR
• Parse scanned documents with Google Document AI
• Process invoices, receipts, and forms for structured data

Prerequisites

• robomotion CLI installed
• Package installed: robomotion install googlevision
• Google Cloud Vision / Document AI credentials configured via Robomotion vault

IMPORTANT: Session Mode Required for Multi-Step Operations

Each CLI command runs as a separate process — connection IDs from connect do NOT persist across calls. You MUST use --session on connect and pass --session-id to all subsequent commands.

Workflow

1. Install (once): robomotion install googlevision
2. Connect with session:

   robomotion googlevision connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   

3. Use the returned client-id and session-id in all subsequent commands:

   robomotion googlevision detect_text --client-id "<client-id>" --image-path <file> --session-id "<session-id>" --output json
   

4. Disconnect when done:

   robomotion googlevision disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   

Always append --output json to get structured JSON results.
