Salvo Measure

Photo

Include something of known size in frame — a tape measure, A4 sheet, or coin — for accurate measurements. Without one, you'll still get a category ID, but area/volume/mass won't be available.

Set scale reference

I already know the item's dimensions

Enter the measured footprint directly — this skips tracing the outline on the photo.

Length (mm)

Width (mm)

Area is calculated as length × width (a rectangle). For irregular shapes this will overstate area slightly — trace the outline instead for a closer figure.

Pick a reference object, then tap its two end points on the photo.

Reference object

Length (mm)

Skip this step if you don't have a reference object — you'll still get a category ID, without measurements.

Trace footprint

Tap points around the item's outline (the face visible in the photo). At least 3 points. Tap "Finish outline" when done.

Depth / thickness

The camera only sees one face. Enter the item's depth (front-to-back thickness) to convert area into volume. For flat stock (flooring, slate, brick) a category default is suggested after classification — for irregular 3D items, measure and enter it yourself.
