Dual-mode data capture system for collision detection and object dimensioning

Abstract:

A dual-mode data capture system includes a capture controller, a point cloud generator, a collision detector, a plurality of cameras viewing a capture volume, and a motion sensor to generate a detection signal when an object arrives at a capture position within the volume. The controller: activates a subset of cameras in a collision detection mode to capture sequences of images of the volume; responsive to receiving the detection signal, activates the cameras in a dimensioning mode to capture a synchronous set of images of the capture position. The collision detector: determines whether the sequences of images indicate a potential collision; and responsive to detection of a potential collision, generates a warning. The point cloud generator: receives the synchronous set of images and generates a point cloud representing the object based on the synchronous set of images, for use in determining dimensions of the object.
