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.
