Abstract: A data capture system includes: a first capture node including: a first set of image sensors, and a first computing device connected with the first set of image sensors and configured to: control the first set of image sensors to capture respective images of an object within a capture volume; generate a first point cloud based on the images; and transmit the first point cloud to a data capture server for dimensioning of the object; and a second capture node including: a second set of image sensors, and a second computing device connected with the second set of image sensors and configured to: control the second set of image sensors to capture respective images of the object; generate a second point cloud based on the images; and transmit the second point cloud to the data capture server.

Abstract: A server includes a communications interface; and a processor connected with the communications interface, the processor configured to: receive, from each of a plurality of capture nodes: (i) an initial point cloud depicting a portion of a capture volume, and (ii) boundary values corresponding to the initial point cloud; generate a bounding box from the boundary values received from the capture nodes; select respective portions of each initial point cloud based on the bounding box; and combine the selected portions to generate a combined point cloud.
