Abstract
A method and apparatus for a chip tracking system. A chip tray is positioned above a light-diffusion box. The chip tray has a transparent portion for a column of the chip tray One or more image sensors are positioned with a viewing perspective of chips through a transparent portion of an underside of the chip tray A tracking controller is configured to illuminate the light-diffusion box with diffused light that shines through the transparent portion of the chip tray and illuminates the edge of one or more chips in a chip stack visible via the transparent portion. The one or more image sensors capture an image of one or more chips in the column in response to illumination of the light-diffusion box. The tracking controller analyzes, via a neural network model, a color pattern on the edge of the one or more chips. The tracking controller associates the color pattern on the edge of the one or more chips with a denomination value for the chip stack. The tracking controller determines, using a range imaging device, a height of the chip stack. Further, the tracking controller computes a monetary value of the chip stack based on the denomination value, the height of the chip stack, and a …
