Abstract
Images of a fixture such as a shelf holding items may be acquired by cameras and processed to count the quantity of items at the fixture. A top of an item is determined in the image. Given information about the items designated for stowage at the fixture and the location of the top, a three-dimensional (3D) bounding box indicative of a volume is determined relative to the fixture. Bounding boxes which extend outside the boundaries of the fixture are disregarded. Remaining bounding boxes may then be analyzed to determine a measured height of the item(s) in a stack. The measured height may be divided by a per-item height to determine a quantity of items in the stack. The quantities in multiple stacks may be summed to determine a quantity at the fixture.
