Abstract: A data capture system for object dimensioning includes: a motion sensor configured to generate a detection signal responsive to detecting an object at a capture position within a capture volume; a capture controller connected to the motion sensor and configured, responsive to receiving the detection signal, to generate and transmit a shutter command substantially simultaneously to each of a plurality of cameras that causes each camera to capture a respective image of a synchronous set of images of the capture volume; an image processing server connected to each of the plurality of cameras and configured to receive the synchronous set of images from the cameras, and to store the synchronous set of images in a common repository; the image processing server further configured to generate a point cloud representing the object based on the synchronous set of images, for use in determining dimensions of the object.
