Real-Time Fabric Measurement Tool

I’m building an in-house setup that measures fabric length, width and overall size straight from a live camera feed. I already have the camera hardware in place; what I’m missing is a reliable Python solution—preferably based on OpenCV or a similarly robust library—that can:

• Detect the edges of the fabric in each frame,
• Convert pixel counts to real-world units using a reference marker, and
• Return clear text output with the exact dimensions for every sample we capture.

Accuracy is critical; the readings need to stay consistent even if lighting shifts slightly or the cloth pattern varies. A short calibration routine at start-up is fine as long as it’s quick and repeatable.

Deliverables
1. Well-commented Python code (stand-alone or Jupyter notebook) that connects to the camera, performs real-time processing, and prints the length and width.
2. A brief README explaining camera settings, calibration steps, and any third-party modules used.
3. Sample test run or short video/GIF that proves consistent dimension reporting.

I’m happy to test early builds on my machine, so incremental commits are welcome.
