Could you build this?
Partial While querying the Lichess API for Stockfish analysis is simple, detecting 3D-angled chessboards, segmenting 64 squares, and classifying chess pieces under diverse real-world lighting and physical sets requires specialized computer vision models.
What it would actually take: The core pipeline requires a custom computer vision model trained to detect chessboard corners (homography/perspective transform) and an object detection or classification model (such as a fine-tuned YOLO or CNN) to classify each of the 64 squares across varied physical piece designs, materials, and angles. Once converted to a FEN string, the position is rendered in a native chess board component and sent to Lichess or an on-device Stockfish binary. Building the vision pipeline requires a curated dataset of annotated real-world chessboard photographs and ML engineering expertise.
