Title:
COMPOSITION ANALYSIS METHOD FOR ELECTRONIC/ELECTRICAL EQUIPMENT COMPONENT WASTE, PROCESSING METHOD FOR ELECTRONIC/ELECTRICAL EQUIPMENT COMPONENT WASTE, COMPOSITION ANALYZER FOR ELECTRONIC/ELECTRICAL EQUIPMENT COMPONENT WASTE, AND PROCESSING DEVICE FOR ELECTRONIC/ELECTRICAL EQUIPMENT COMPONENT WASTE
Document Type and Number:
WIPO Patent Application WO/2021/201250
Kind Code:
A1
Abstract:
Provided are a composition analysis method for electronic/electrical equipment component waste, a processing method for electronic/electrical equipment component waste, a composition analyzer for electronic/electrical equipment component waste, and a processing device for electronic/electrical equipment component waste which can efficiently analyze the composition of component waste in the electronic/electrical equipment component waste in a short time regardless of the experience and skill of each individual. The composition analysis method for electronic/electrical equipment component waste is characterized by comprising: extracting electronic/electrical equipment component waste from a captured image obtained by capturing a plurality of electronic/electrical equipment component wastes including a plurality of types of components; assigning, to the extracted electronic/electrical equipment component waste, a recognition frame including an image encompassing the electronic/electrical equipment component waste and a background surrounding the electronic/electrical equipment component waste; estimating for the respective component types, on the basis of component type area ratio data containing information on the area ratio of the electronic/electrical equipment component waste to the recognition frame, the total area of the electronic/electrical equipment component waste with the assigned recognition frame; multiplying the total area estimation result by assumed weight per unit area for the respective component types; and analyzing the weight ratio of the electronic/electrical equipment component waste for the respective component types to thereby analyze the composition of the electronic/electrical equipment component wastes in the captured image.
