Abstract
Described herein are a system and methods for generating 3D models using imaging data obtained from an array of camera devices. In embodiments, a stochastic shape distribution may be applied upon an object to be modeled in invisible ink. The system activates a first lighting mode which causes the stochastic shape distribution to be visible and captures a first set of images that depict the stochastic shape distribution on the object. The system then activates a second lighting mode that causes the stochastic shape distribution to be hidden and captures images of the object as it would normally appear (without the stochastic shape distribution). The images having the stochastic shape distribution may be used to determine alignment information for the images within the set of images. That alignment information may then be attributed to the second set of images and used to generate the 3D model.
