DETECTION AND TRACKING OF ITEM FEATURES

摘要

Technologies are generally described for detection and tracking of item features. In some examples, features of an object may be initially found through detection of one or more edges and one or more corners of the object from a first perspective. In addition, determination may be made whether the detected edges and corners of the object are also detectable from one or more other perspectives. In response to an affirmative determination the detected edges and of the object may be marked as features to be tracked, for example, in subsequent frames of a camera feed. The perspectives may correspond to distributed locations in a substantially umbrella-shaped formation centered over the object. In other examples, lighting conditions of an environment where the object is being tracked may be programmatically controlled.

主权项

1. A method to implement detection and tracking of item features, the method comprising:
detecting one or more edges and one or more corners of an item from a first perspective; determining whether the one or more edges and the one or more corners of the item are detectable from at least a second perspective; in response to a determination that the one or more edges and the one or more corners of the item are also detectable from at least the second perspective, marking the one or more edges and the one or more corners of the item as features to be tracked; and tracking the item through at least two captured image frames based on a correlation of the one or more edges and the one or more corners.
