Custom Model Training
Bespoke computer vision and OCR model training engineered specifically for non-standard architectural drawings, blueprints, and CAD renders.
Key Extraction Targets
The Problem
Pre-trained models struggle with domain-specific blueprint graphics.
Models trained on COCO or generic web imagery fail when trying to detect CAD line work, architectural hatch patterns, and complex drawing callouts.
System Workflow
How the AI System Works
Data Curation & Synthetic Augmentation
Annotate floor plan features and generate synthetic variations (rotations, scales, noise) to expand training dataset size.
Hyperparameter Tuning & Training
Train state-of-the-art vision architectures (YOLOv8/v10, RT-DETR) with custom anchor boxes tuned to CAD geometries.
Benchmark Evaluation & Quantization
Benchmark against test sets (mAP50-95, IoU, Precision/Recall) and quantize for fast CPU/GPU inference.
