Abstract: A method is provided for controlling forks of a vehicle. The method may comprise: while the forks of the vehicle are moving vertically, acquiring a series of images of a scene of a physical environment in which a plurality of pallets are visible; identifying in each image, by a computer system, one or more scored candidate objects, each potentially corresponding to a respective one of the plurality of pallets; for each of the one or more scored candidate objects, tracking, by the computer system, a respective location in each of at least two images of the series; determining for each of the one or more scored candidate objects a respective, associated height in the physical environment; and stopping, by the computer system, the forks of the vehicle at a height in the physical environment based on the height of a specific one of the scored candidate objects.
