How long does processing take?

Usually a few minutes; large captures take longer. You can close the page and find the model in your library later.

Yes, ideally under an overcast sky, which gives even light. Strong sun creates harsh shadows.

Why scanning instead of AI?

Scanning uses real photos from every side, so it keeps the true shape. AI guesses the back of the object from a single image.

3D scanning with a phone for students: a step-by-step guide

8 min read

Phone 3D scanning starts from many photos of the same object, taken from every side. 3D processing finds the common points and rebuilds the shape and texture. It is the most faithful way to bring a real object into 3D, and students can do it themselves.

What you need

A phone with a normal camera. No special sensors required.
An object that does not move, from mug size to chair size.
Room to walk around it, or a stool or turntable you can rotate.
Even lighting and 5–10 minutes.

Objects that scan well

Matte objects with texture and detail: wood, stone, clay, unglazed ceramics, plush toys, plants, fruit, cardboard models. Processing needs visible surface features to match photos to each other.

Poor results: glass and transparent objects, mirrors, polished metal, plain white or black surfaces without texture, and very thin parts such as wires.

Step by step

1Place the object on a table, away from the wall. A newspaper or a finely patterned cloth underneath helps orientation.
2Use ceiling light or a window. No flash and no harsh shadows.
3First round: at object height, walk slowly in a circle and take a photo every small step so neighbouring photos overlap a lot.
4Second round: raise the phone and look down at about 45°, another full circle.
5A few close-ups of details and the top.
6Check that the whole object is in every frame and photos are sharp. In total, 30–80 photos are usually enough.
7Send the capture to 3D processing and wait for the model.

Video instead of photos

You can film a 30–60 second clip walking slowly around the object. It is more convenient, but video frames are usually less sharp than photos; if the result is blurry, redo it with photos.

Common problems

The object moved (someone bumped the table): the model comes out doubled or broken.
Too few photos from one side: a hole appears exactly there.
Lighting changed between rounds: colours look patchy.
Busy background with people walking through: processing gets confused.

Scan objects, not classmates: faces and people are personal data. Ask a museum's permission before publishing models of its exhibits.
