Once the files are uploaded, you can press the button for Create Photo Scene. I prefer to wait for the upload part of the process, in case there are problems. You'll need to enter your email address, and a descriptive name for the scene. You'll be asked whether you want to wait, or be sent an email when the process is done.
(You can use the Ctrl-A shortcut to select all, or click the first file, and then Shift-click the last file to get them all). Navigate to the folder where you put your photos, and select them all.
You'll get a dialog prompting you to select image files. Open the 123D Catch application, and click the button for "Create a New Photo Scene". Now we'll submit the photos to the 123D Catch web service, to create a photo scene. When you're done taking pictures, save them all to a folder with a descriptive name. Since the distance to the object will be consistent, you might want to focus manually. If you're using the camera rig I referenced earlier, adjust the horizontal distance on the rig, and the camera zoom, so that the object fills the frame. There are extensive tutorials available here:
While it is not absolutely necessary to maintain the same distance from the object all the way around, it does help the algorithm if distances are consistentĬonsistent diffuse lighting all around the object works best.Īccurate focus is important - you will want to remove any out of focus shots The target object should take up most of the frame: either get close to the object or zoom in In effect, once the object is in place, you should move around it The object should not be moved at all during capture, and lighting should remain consistent. Notice how the bear is sitting on tiny circular stage. A good approch is to take 20 objects all the way around, and then move up (pointing the camera down at the object) and take another 20Ĭhoosing a smaller platform for the object helps capture more details from below. Photographs should capture all sides of the target object, both all the way around, and top and bottom. In this example, I've used my son's favorite teddy bear. The first step is to take a number of photographs (between 20 and 40) of your object, so that 123D Catch can assemble a 3D model.
