DIMENSION DETECTION DEVICE AND DIMENSION DETECTION METHOD

A dimension detection device includes: a frame, a detection area being disposed on the frame; two first dimension detection apparatuses disposed on the frame, the two first dimension detection apparatuses being positioned on two opposite sides of the detection area; and two second dimension detection apparatuses disposed on the frame, the two second dimension detection apparatuses being positioned on other two opposite sides of the detection area. The first dimension detection apparatus includes a first motion apparatus and a first image acquisition assembly, and the first motion apparatus is capable of driving the first image acquisition assembly to move. The second dimension detection apparatus includes a second motion apparatus and a second image acquisition assembly, and the second motion apparatus is capable of driving the second image acquisition assembly to move.
