A fork-lift truck includes a load carrier, a first optical detector, an optical analyzing unit, and a second optical detector. The analyzing unit receives and analyses information from the second optical detector, wherein the first and second optical detector are movable together with the load carrier, and the first optical detector is positioned in relation to the load carrier, such that a first field of view includes at least a part of the load carrier and an extension of the load carrier. The second optical detector is positioned, such that a second field of view includes a predetermined volume above the load carrier The position and orientation of the second detector is calibrated in relation to a predetermined position on the fork-lift truck, in case one or more objects are positioned in the predetermined volume, at least one three-dimensional relative position can be determined.
