Abstract

Systems and techniques for real-time 3D reconstruction with a depth camera are described herein. Depth measurements received from a depth camera of target may be stored in a depth-measurement data structure. A three-dimensional representation of the target may be stored in a model. A current depth image received from the depth camera may be registered to the model. The depth-measurement data structure may be modified with the current depth image based on the registration. The model may be deformed based on space carving and the modified depth measurement data structure.

Background

3D modeling (e.g., reconstruction) of a target (e.g., object of interest) from image data is a popular computer vision topic. In creating a 3D model of the target from image data, a popular usage (user experience) is to hold the camera in hand and move the camera around the target while displaying to the user a 3D model of the object in real-time and the current camera pose relative to the object. Alternatively, the camera may be held stationary and a turntable may be used to rotate the object. In either scenario, different facets of the target are exposed to the camera in order to gather information to create the 3D model.
