# Rust Auto Score Engine

A high-performance dart scoring system architected in Rust, utilizing the Burn Deep Learning framework. This engine is the high-concurrency Rust port of the original Python-based [Dart-Vision](https://github.com/iambhabha/Dart-Vision) project.

## Live Demo (No Server Required)

The entire neural engine can run directly in your browser using **WebAssembly (WASM)**. No installation or heavy server is required.

**Try it here (WASM):** [https://iambhabha.github.io/RustAutoScoreEngine/](https://iambhabha.github.io/RustAutoScoreEngine/)
**Try it here (Hugging Face Space):** [https://huggingface.co/spaces/bhabha-kapil/RustAutoScoreEngine](https://huggingface.co/spaces/bhabha-kapil/RustAutoScoreEngine)

## Technical Overview

The engine implements a multi-stage neural pipeline designed for millisecond-latency inference and robust coordinate recovery.

### Neural Pipeline Workflow
- **Input:** 800x800 RGB Image Frame.
- **Mapping:** YOLOv4-tiny backbone extracts point-of-interest features.
- **Verification:** Keypoint confidence filtering and objectness thresholds.
- **Symmetry Recovery:** Mathematical reconstruction of obscured calibration points.
- **Scoring:** BDO standard coordinate mapping for final point calculation.

## Installation and Setup

### Prerequisites
- **Rust Toolchain:** Stable channel (Latest).
- **GPU Driver:** Support for Vulkan, Metal, or DirectX 12 (via WGPU).
- **Hard Drive Space:** Minimum 1GB (excluding dataset).

### Initial Setup
1. Clone the repository.
2. Ensure `model_weights.bin` is present in the root directory.
3. For local dashboard, run the `gui` command.
4. For custom training, place images in `dataset/800/` and configuration in `dataset/labels.json`.

## Advanced Architecture and Optimization

### 1. Distance-IOU (DIOU) Loss Implementation
Utilizing DIOU Loss ensures stable training and faster convergence for small objects like dart tips by calculating intersection over union alongside center distance.

### 2. Deep-Dart Symmetry Engine
If a calibration corner is obscured, the system invokes a symmetry-based recovery algorithm to reconstruct the board area without recalibration.

### 3. Memory & VRAM Optimization
Optimized to handle 800x800 resolution training on consumer GPUs by efficiently detaching the Autodiff computation graph during logging cycles (Usage: ~3.3GB VRAM).
