1. A terminal for measuring at least one dimension of an object, comprising: a pixel array; a range camera that projects a visible laser pattern of an outlined shape onto the object, the outlined shape corresponding to the range camera's field of view; a visible camera that produces a visible captured image of an area in which the object is located such that the outlined shape is within the visible camera's field of view; a processor, calculating from the visible image projected onto the pixel array, at least one divergence angle of the laser pattern, a number of pixels in the pixel array corresponding to the laser pattern, and at least one dimension of the object, wherein the divergence angle of the laser pattern is visible on the object and on the pixel array; and a display connected to said processor, wherein the display presents information associated with an optimal orientation of the range camera and visible camera with respect to the object, and wherein: the range camera's field of view is narrower than the visible camera's field of view; and the display presents (i) the visible image produced by the visible camera and (ii) an outlined shape on the displayed visible image corresponding to the range camera's field of view.
