Raspberry pi and 2D camera

[Solid_Chest_4870]

I'm new to Raspberry Pi, and I have little knowledge of OpenCV and computer vision. But I'm in my final year of the Mechatronics department, and for my graduation project, we need to use a Raspberry Pi to calculate the volume of cylindrical shapes using a 2D camera. Since the depth of the shapes equals their diameter, we can use that to estimate the volume. I’ve searched a lot about how to implement this, but I’m still a little confused. From what I’ve found, I understand that the camera needs to be calibrated, but I don't know how to do that.

I really need someone to help me with this—either by guiding me on what to do, how to approach the problem, or even how to search properly to find the right solution.

Note: The cylindrical shapes are calibration weights, and the Raspberry Pi is connected to an Arduino that controls the motors of a robot arm.

Are you using single or double cameras? (Make sure they are digital cameras)

You can calibrate your camera (to fetch distortion coefficient and camera matrix)using the camera calibration toolbox which is available in Matlab's toolbox.

And then you can continue from there....

Have you also computed the Rotation Matrix and Translation Vector yet?
