How to calibrate a 3D camera?

Hey I’m using a 3D camera (ToF camera). On the internet I didn’t find a clear way to calibrate this camera.

I receive a luminance image and a depth image (radius distance). This is what I have in mind for calibration method.

Put a checkerboard pattern on a table. Now use this pattern to determine the intrinsic and extrinsic parameters: extrinsic: so I can use this pattern to create a new base where the checkerboard is the new (x,y)-plane (z=0). intrinsic: the x, y, (z?) values of the squares should be correct now.

Which functions do I need to use to achieve this? Or what is the conventional way to calibrate a ToF-camera?

Thank you.

Hi,

There are functions and applications available with Computer Vision System Toolbox that might help you with your query. The following documentation links might help you get started with calibration:

• What is Camera Calibration?
• Estimate geometric parameters of a single camera
• Single Camera Calibrator App

If you do not have access to the following links, then I would recommend you to contact MathWorks Technical Support in the corresponding region to get to know the steps further. Use this link to contact MathWorks Technical Support:
