How to photograph rebar for counting

  1. 1

    Photograph the cut ends

    Aim straight at the bundle, not along the ribbed sides. Each visible circular end should belong to one bar.

  2. 2

    Keep the whole bundle sharp

    Step back enough to fit all the bars, then focus on the end face. Avoid camera shake and deep shadows between bars.

  3. 3

    Review dense clusters

    Zoom into tightly packed sections and the outer edge. Touching ends, rusty surfaces and uneven bar lengths can make individual bars harder to separate.

Clear, visible cut ends make missed or extra markers easy to spot.

When to count rebar from a photo

Site engineers and material clerks count rebar when a delivery arrives, checking the number of bars in each bundle against the delivery note before signing for it. Stockyards and fabrication shops count again before a load leaves. Photograph the cut ends of each bundle, check the markers and keep the saved image, which shows the total and the date, with the paperwork.

Questions about counting rebar

Will the ribs along a bar be counted?

Use an end-on photo so the model sees cut faces rather than ribs. If the image mostly shows the sides, retake it before counting.

How do I keep a record of the checked quantity?

Review and correct the markers, then download the marked image.
