iRVision Part Z Height & Offset Frame

In this session, we will go over two critical concepts in FANUC iRVision: Offset Frames and Part Z Height. These features play a key role in ensuring accurate part location and positioning in 2D vision processes. Whether you are working with R-30iB, R-30iB Plus, or R-50 controllers, understanding how these fields interact will help you optimize your vision applications.

We will start by explaining what an offset frame is and why it matters. The offset frame defines the plane in which the part moves, and it becomes essential when working with multiple planes or varying part positions. You’ll learn how this differs from the application frame and why, in most cases, leaving the application frame at zero is the best practice.
 

Next, we will cover Part Z Height—a parameter that ensures accurate XY measurements by accounting for the distance between the camera and the part. This is especially important when using perspective calibration, which allows the system to calculate precise measurements even when parts are at different distances from the camera.
 

Throughout the video, we will explore practical examples, including:

• Fixed frame setups where the camera is mounted above a surface.
• Tool frame configurations for applications involving robot-mounted cameras.
• Scenarios where the camera is angled relative to the part and how calibration compensates for distortion.

Requirements for accurate vision setup:

• Proper calibration using perspective projection.
• Defining offset frames correctly for your application.
• Setting accurate Part Z Height values.

What you will learn:

• How offset frames improve flexibility in vision processes.
• Why Part Z Height is critical for precision.
• Best practices for camera positioning and calibration.

If you want to improve your iRVision accuracy and reduce errors in part location, this video will give you the foundation you need.
