INTERACTIVE AND AUTOMATIC 3-D OBJECT SCANNING METHOD FOR THE PURPOSE OF DATABASE CREATION

摘要

Systems, methods, and devices are described for capturing compact representations of three-dimensional objects suitable for offline object detection, and storing the compact representations as object representation in a database. One embodiment may include capturing frames of a scene, identifying points of interest from different key frames of the scene, using the points of interest to create associated three-dimensional key points, and storing key points associated with the object as an object representation in an object detection database.

1. A method of capturing compact representations of three-dimensional objects suitable for object detection comprising:
capturing, using a camera module of a device, a plurality of images of a scene, wherein each of the plurality of images of the scene captures at least a portion of an object; identifying a first key frame from the plurality of images and a first position of the device associated with the first key frame; identifying a second key frame from the plurality of images and a second position of the device associated with the second key frame, and wherein the second position is different from the first position; identifying a first plurality of points of interest from the first key frame, wherein each of the first plurality of points of interest identify one or more features from the scene; identifying a second plurality of points of interest from the second key frame, wherein each of the second plurality of points of interest identify one or more of the features from the scene; matching a subset of the first plurality of points of interest and a subset of the second plurality of points of interest; identifying a plurality of key points associated with the object based at least in part on the matching of the subset of the first plurality of points of interest and the subset of the second plurality of points of interest; and storing at least a portion of the plurality of key points associated with the object as an object representation in an object detection database.
