Abstract
Footprint data of an item that is representative of a boundary of the item and where that boundary is located is obtained using occlusion of a projected line. Line projectors are arranged at opposite sides of a conveyor belt and at an angle that is acute with respect to a plane of the conveyor belt and produce lines on the conveyor belt within a measurement area. As an item moves past the measurement area, the sides of the item occlude a portion of the projected lines. Cameras acquire a series of images as the object moves with respect to the measurement area. The images are processed to determine where the projected lines were occluded. An edge point is then determined representative of that location. One or more lines may be fitted to a plurality of edge points to determine the boundary of the item.
