The invention discloses a dual spectrum technology based leaf and stalk separating and
cutting quality detection device and detection method. The detection device comprises a spreading device (1), a paving
machine (2) arranged under the spreading device (1), an
X ray detector (3) arranged under the paving
machine (2), a visible
light detector (4) arranged under the outlet of the
X ray detector (3), a receiving device (6), a frame (5), and a control cabinet (7). The receiving device (6), the frame (5), and the control cabinet (7) are arranged under the outlet of the visible
light detector (4).By adopting a visible light and
X ray imaging technology and corresponding image
algorithm, the
tobacco leaf area, tobacco stalk area, and tobacco stalk length can be obtained; the leaves and stalks in a same image do not need to be separated, and the identification accuracy of
image detection is improved. The leaf structure and long stalk rate can be detected, the stalk containing rate of leavesand leaf containing rate of stalks can be detected, the stalk density and leaf density are not needed during the index calculation process, and the leaf
cutting quality indexes can be automatically calculated out.
