123D Catch is a new application and service from Autodesk that turns a series of photographs into a 3D model of an object or space.
The rig described here helps you structure the photos for best results. It lets you spin the camera around the object at a constant height and distance, while the object stays still. You can easily move the camera up and down to get top and bottom angles.
For this project, you will need:
3x 36" long 1" dia dowel
1x 12" long x 3/4" thick x 2" wide plank
1x 8" x 8" x 3/4" board
1x 6" x 6" x 3/4" board
38x #8 3/4" construction screws
4x #8 3/4" hex bolt
1x #8 1" hex bolt
5x #8 wing nuts (6x optional)
2x #8 lock washers (3x optional)
1x 1/4" x 3/4" thumbscrew
1x 1/4 washer
2x casters (the base should not exceed 2" in depth)
Step 1: Print the Plastic Parts
You will need a 3D printer, such as a Makerbot, or access to one via a 3D printing bureau such as Shapeways or Ponoko. You will need to print:
3x shaft collar
1x camera ring
1x camera platform
1x extension arm (optional)
Download the files and print them yourself, or send them to a service. They are also hosted on Thingiverse.
