DEPTH-BASED ANALYSIS OF PHYSICAL WORKSPACES

摘要

Systems and methods are provided for dynamically performing depth-based analysis of a physical workspace. The system includes a depth camera to generate three dimensional (3D) images, and a controller. The controller is able to acquire a stream of 3D images, calculate distances between the depth camera and objects represented by 3D pixels within the 3D images, identify an increase in distance between the objects and the depth camera, detect a pause, and define a reference surface during the pause. The controller is also able to identify a change in distance between the objects and the depth camera after defining the reference surface, to identify a segment of the current 3D image close to the depth camera, and to determine a gesture location within the current 3D image based on the identified segment. A data set corresponding to the gesture location then adjusts an output of a display.

1. A system comprising:
a depth camera operable to generate three dimensional (3D) images of a physical workspace; and a controller operable to acquire a stream of 3D images from the camera, to calculate distances between the depth camera and objects within the physical workspace that are represented by 3D pixels within the 3D images of the stream, to identify an increase in distance between the objects and the depth camera over time based on the 3D pixels, to detect a pause following the increase in distance, and to define a reference surface corresponding to a 3D image of the physical workspace during the pause, wherein the controller is further operable to identify a change in distance between the objects and the depth camera for a current 3D image acquired after defining the reference surface, to identify a segment of the current 3D image that is closer to the depth camera than the reference surface, and to determine a gesture location within the current 3D image based on the identified segment, wherein the controller is further operable to identify a data set corresponding to the gesture location, and adjust an output of a display based on information in the data set.
