| # Automatic trading card sorter # Team Members: - Andrejun Agsalud (agsalud2) - David Medina (davidrm3) - Steve Guzman (steveg3) # Problem Trading cards have become a market which have sold collectibles for as high as thousands of dollars. Knowing this, it has become important to be able to differentiate and sort cards when trying to sell. The problem is that some people own thousands of cards. Going through each card individually to find what’s worth selling as a single and what can be sold in bulk would take a significant amount of time. # Solution We plan to automate the process of sorting trading cards using OpenCV to control a machine to sort cards into separate bins. The machine would take a single card out of the card holder and place it into a spot to be read by a camera and raspberry pi using OpenCV. Using info from the pi, the machine would place the correct bin to the correct place before dropping the card off. # Solution Components ## Mechanical module This system will encompass a physical card holder that will be emptied out by two wheeled motors that will grab one card and move it onto a conveyor belt. Once on this belt, powered by another set of motors, the camera will detect what color the card is and move the card to the appropriate grouping. This could be achieved through rotating banks that will organize the cards into different slots or a set of banks in sequence for them to drop into, another set of motors will be needed to move the card off the camera spot. To sense the distance the cards will be moving, we can use software to calculate the distance of each step of a stepper motor. ## Card Analysis This will consist of a raspberry hat that will allow for the use of a small esp32 camera that will be sending its picture to the raspberry pi for OpenCV analysis. The module itself will house the camera and the pi since both will need to be in communication with each other. From here, the module can then send the necessary signals to the mechanical module for reading of the next card. Raspberry Pi Pi-cam Other resistors/regulators for the motors # Criterion For Success To demonstrate the success of the project, a deck of pokemon cards should be able to be inserted and sorted by color in a reasonable manner. This should function without any of the cards being damaged and without jamming. If an error occurs, there should be a mechanism to stop the system for the user to see what has happened and reset. Correct calculations for stepper motors to move the card into camera and sorting bins 90% color rating accuracy for the camera. |
