Introduction to 3D Capture
In order to understand 3D capture, we need to familiarise ourselves with the concept of stereoscopic vision. When looking at an object, each of our eyes perceive it in a different way. Our brain analyses the vision it receives from both eyes and interprets it as depth. Similarly, capturing 3D information requires two cameras to perceive depth. The Microsoft Xbox Kinect uses this (in addition to an infrared sensor).
In order to see 3D images, special viewing glasses can filter out superimposed images or videos so each eye receives its correct perspective.
In this module we use a Structure Sensor to capture objects (or people) and then explore more 3D modelling techniques.
Many apps including 123D Catch uses the phone's camera to capture 3D objects. However this stitches together multiple photos (like a panorama) to recover the original object. It is good at capturing colour, but not depth; therefore its use is preferred for simple objects and shapes.
