The invention discloses a cup-rim height measuring device and method. The height measuring precision for the rim of a cup to be measured is improved on the premise that the circuit complexity of a measurement array is not increased. The measuring device comprises a base, an emission plate, a slot laser linear array, a photoresistance sensor array and a reception plate; the emission plate and the reception plate, opposite to the emission plate, are fixedly connected onto the base, and a contact line between the reception plate and the base is parallel with the emission plate; the emission plateis vertical to the base; the slot laser linear array is fixedly connected with the emission plate, and the photoresistance sensor array is fixedly connected with the reception plate; an angle theta is formed between straight lines where different rows of the photoresistance sensor array are positioned and a straight line parallel with both the emission plate and the base; and an angle theta is formed between an intersect
