Progress photo analyzer

Field Progress Photo Analyzer

Business Case

Site photos document progress but are often poorly organized. This skill provides systematic photo cataloging and analysis.

Technical Implementation

Quick Start

analyzer = ProgressPhotoAnalyzer("Office Tower")

photo = analyzer.catalog_photo(
    filename="IMG_001.jpg",
    captured_date=datetime.now(),
    category=PhotoCategory.PROGRESS,
    location="Column Grid B-3",
    level="Level 5",
    captured_by="Site Super",
    tags=["concrete", "forming"]
)
