card-detector

Simple system for real-time playing card detection, written in Python

Usage

python3 CardDetector.py

Used modules

• OpenCV
• NumPy
• PiCamera - (basicaly works with any other module but some reimplementations in Camera.py are needed)

Tested on:

• Raspberry Pi 3B+ with PiCamera
• Raspbian

Simplified working algorithm

for frame in stram:
    cards = detect_all_cards_present()
    for card in cards:
        rank_part, suite_part = zoom_card(card)
        rank_diff, rank = match_rank(rank_part)
        suite_diff, suite = match_suite(suite_part)
        if rank_diff < RANK_THRESH and suite_diff < SUITE_THRESH:
            make_an_overlay_on_card(card=card, rank=rank, suite=suite)
