Abstract: The present invention discloses a novel color based optical grading system with multi-reflectance and multi-angle views for grading objects of different external characteristics, and a novel color based optical grading method for grading objects based on different external characteristics. The system comprises of: multiple advanced optics units and at least one master controller. Each optics unit comprises of multiple programmable cameras, multiple spectral light sources, multiple adjustable mirrors/prisms, a mirror/prism adjustment assembly to ensure the enhanced surface analysis of the objects; at least one backlighting domes to provide uniform backlight for capturing objects in multi-reflection and multi-angle views and at least one image processing unit for processing images of each objects.

Abstract: The present invention discloses a multi-channeled grading machine with trajectory tracking sensor network for grading objects into multiple grades in a single pass based on external characteristics viz. size, shape, color, texture, surface properties or any other possible external characteristics by continuously tracking the trajectory of objects. The grading machine comprises of hopper; at least one feeding unit; multiple optics units multiple conduits; multiple sensor networks in multiple conduits; at least one master controller; at least one ejector unit comprising of arrays of single-angled or multiple angle ejectors in each conduit; multiple vacuum creators placed respectively opposite to each ejector; multiple collecting chutes; and multiple collecting locations. The grading machine is extremely simple, accurate, and automated, power-efficient and cost-effective.
