Placing canvas, size/calibration/scaling

jordy_keller — Tue, 02 Jul 2024 19:19:17 GMT

Hi,

I would like to develop a workflow for importing canvasses of a known size.

I tested importing jpg's of sizes 500x500, 1000x1000, 4056x3040 and 3040x4056.

When I import these jpg's as canvas and leave scale at 1, they all come into fusion with a width of 17.5 mm.

I would like to know if this is a given/constant that I can work with.

My question is, will any image used as a canvas come in at a width of 17.5 mm regardless of the resolution?

Is there any setting or other factor that determines how canvasses are sized when placing?

I would like a consistent workflow of placing a canvas and scaling it to actual size, maybe even by scripting.

But how consistent and reliable is the scaling (to 17.5) when placing a canvas?

Thanks!

EDIT: My goal:

I want to have a static (Pi HQ, 4056x3040px) camera pointed at a static surface to place objects on.

I want to skip the calibration step, i want to enter a constant value for scaling when placing the canvas.

If I know the actual width of the image area I can calculate a constant scaling factor when placing the canvas.

But where does this 17.5mm come from? Is this a setting/constant that I can rely on?

EDIT: Adding image to illustrate.

Hi,

Canvases are calibrated according to the real dimensions (right-click > Calibrate)

Thanks Gunther, I know about calibration but I want to skip this step.

I edited my post to clarify.
