Abstract: In some implementations, a robotic device may receive, from a first light detection and ranging (LIDAR) sensor and a second LIDAR sensor, calibration data associated with a physical environment of a robotic arm of the robotic device. The robotic device may determine, based on the calibration data, a configuration of a boundary for the robotic arm. The robotic device may position, relative to the robotic arm, the first LIDAR sensor at a first position and the second LIDAR sensor at a second position to sense an activity within the boundary. The robotic device may monitor the boundary based on first sensor data from the first LIDAR sensor and second sensor data from the second LIDAR sensor. The robotic device may disable, based on the first sensor data or the second sensor data indicating the activity associated with the boundary, the robotic arm from moving within the boundary.

Abstract: A plurality of three-dimensional (3D) cameras is deployed about a zone through which freight is conveyed to a shipping container. The 3D cameras have sensors with fields of view over which a plurality of point clouds of voxels are captured from the freight. A server combines the point clouds to obtain a composite point cloud of the freight, encloses the composite point cloud with a bounding box having dimensions, and dimensions the freight from the dimensions of the bounding box. An optional scale weighs the freight while it is being dimensioned and moved through the zone.

Abstract: A method and apparatus for synchronizing image frame capture timing for a plurality of fixed-frame rate image sensors having the same frame rate is disclosed. An example includes a processing system connected to image sensors in a venue for capturing image frames and determining a capture offset for each image sensor, against a common, independent time base. The processing system determines when the capture offset of any of the image sensors is above a threshold offset value and, in response, a restart signal is sent to the image sensor to restart the image sensor for capturing images within the venue at another capture offset. The process will continue for that image sensor until the image sensor has a capture offset within below an acceptable threshold value.
