123Catch Web App Photos
Scan of bottle on white background. Photos taken with Canon Rebel T2i. Used flash despite recommendations to get decent lighting.
Tips
- Use graph paper, or something textured as the base for the object that you are trying to capture
- We used a section of graph paper, and that helped capture objects w/the iPad significantly
- Try to make sure photos overlap.
- Don't use a flat background
- Try laying string around the object or hanging it!
- iPad app did not do very well with small objects (ie: Pliers), but did significantly better when:
- A textured background was added to the bottom of the scene
- Larger objects were used (8 to 12" high, ~6" wide / deep)
Pros
Can use any camera, no special app needed Using your own camera and the 123d Catcb web site and/or app gives you much more control. If the process doesn't work, you can try and stitch/correct/upload more images iPad App: gives you a nice simple interface to accomplish the whole process (take picture, upload, process, view if successful)
Cons
Website takes a while to process iPad App: does not give you any options to edit. iPad App: If it fails, you lose everything, including all the photos you took
