System and Method for Generating Fused Infrared (IR) and Visible Light Images of Landfill-Mined-Residues (LMR) Coarse Fractions
Abstract

In this invention, a system and method for generating fused infrared (IR) and visible light images of landfill-mined-residues (LMR) coarse fractions using greenhouse conditions are disclosed. The system comprises an acrylic box with a metallic sheet at its base for placing samples of LMR. An IR camera mounted on a slider sheet within an acquisition module captures IR images at a first height, while a visible light capturing device captures images at a second height. Exposed to direct sunlight, the system generates a greenhouse effect to heat the samples. A computing device then receives the IR and visible light images, automatically generating fused images. These images enhance the material classification process, aiding in efficient waste segregation and resource recovery.

Societal Impact

This technology can significantly improve landfill mining efficiency, reducing landfill waste and its associated environmental hazards. By enhancing waste segregation, it can facilitate better recycling and reuse of materials, contributing to sustainable development and reducing the environmental footprint of landfills.
