Makerscanner
Flat color background. Camera is fixed distance from background. Makerscanner is taped down Makerscanner software - Latest as of 3/30/13
Tips
Pros
- Color point cloud in mesh
- Works well for small objects
- High resolution
Cons
- Can't scan all sides at once
- Needs stitching of multiple scans.
- Cleanup of scans needed before usable.
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
123Catch iOS App
Tried same scan with Photos and with app
Tips

- Even distribution of lighting
- Non moving object
- Non reflective object
- X after scan = broken

- Little to no success with Ipad. Iphone app worked well.
ReconstructMe
White background Kinect at 3-4 feet from surface.
Tips
Likes contrast and area to be well lit.
Pros
- Works well for large objects
- Produces PLY
- User can move slowly to make a complete 3D scan.
- Would support turn table.
Cons
- Limited free version. Inserts spheres into model. Can clean up with Meshlab.
