Abstract: Frames of sensor data may be obtained from many sensors arranged throughout a facility. These frames may be time synchronized to support further processing. For example, frames containing image data obtained at about the same time from many cameras within the facility may be used to create an aggregate or “stitched” view of the facility at that time. The synchronization may involve storing the frames from several sensors in buffers. A time window may be specified and used in conjunction with timestamps of the frames to select a set of sensor data from the buffers that are deemed to be synchronized data. The synchronized data may then be used for further processing.

Abstract: This disclosure describes techniques for synchronizing independent data streams. In some instances, a computing device couples to multiple independent sensors, such as cameras, and applies accurate timestamp information to the individual frames of sensor data from the independent sensors. After aligning these data streams by applying these accurate timestamps, the computing device may, in some instances, encode and transmit these timestamped data streams to one or more entities for further processing. In one example, a first camera (e.g., a depth camera configured to generate a depth map) may capture images of an environment, as may a second camera (e.g., an Red-Green-Blue (RGB) camera configured to generate color images). The resulting images may be temporally aligned with one another via the timestamping, and the resulting aligned images from both the depth sensor and the RGB camera may be used to create a three-dimensional (3D) model of the environment.
