Title:
METHOD AND APPARATUS FOR DETECTING DAMAGE IN PLANT PRODUCTS
Document Type and Number:
WIPO Patent Application WO2005060429
Kind Code:
A3
Abstract:
A method and apparatus of sorting plant products based on damage to the plant products is disclosed. A beam emitter (102A, 102B) emits an illumination light toward the outer surface of a plant product. A beam detector (104A, 104B) detects substantially a single wavelength of a reflected light produced by the plant product responsive to the illumination light. A control unit (106) determines at least one of a presence, an amount, and a severity of damage responsive to the reflected light. The control unit (106) assigns a damage category to the plant product responsive to the determination of damage.
