STRATEGIES FOR TRIGGERING DEPTH SENSORS AND TRANSMITTING RGBD IMAGES IN A CLOUD-BASED OBJECT RECOGNITION SYSTEM

摘要

Systems, apparatus and methods for triggering a depth sensor and/or limiting bandwidth and/or maintaining privacy are presented. By limiting use of a depth sensor to times when an optical image alone is insufficient, mobile device power is saved. Furthermore, by reducing a size of an optical image to only the portion of the image needed to detect an object, bandwidth is saved and privacy is maintained by not communicating unneeded or undesired information.

主权项

1. A method in a mobile device for triggering a depth sensor, the method comprising:
capturing an image with an image sensing device; sending at least some of the image to a server to search for an object within the image; receiving an indication indicating the object was not found in the image with sufficient certainty; enabling the depth sensor and capturing depth information; converting the depth information into a depth map; and sending at least some of the depth map to the server.
