1. A terminal for measuring at least one dimension of an object, the terminal comprising: at least one imaging subsystem comprising an imaging optics assembly operable to focus an image onto an image sensor array, said imaging optics assembly having an optical axis; an actuator operable connected to said at least one imaging subsystem for moving the angle of said optical axis relative to said terminal; wherein said terminal is adapted to obtain a first image of at least a portion of the object; wherein said terminal is operable to determine at least one of a height, a width, and a depth dimension of the object based on effecting said actuator to change the angle of said optical axis relative to said terminal and to obtain a second image of said portion of the object by aligning the second image of said portion of the object with the first image of the portion of the object such that first image data and second image data are obtained along differently orientated optical axes with the images being aligned; and wherein, said terminal calculates the at least one of a height, a width, and a depth dimension of the object with trigonometric relations based on the change of the angle of said optical axis relative to said terminal without moving the terminal.
