MultiCam

MultiCam - Multi-Camera Control System

An mobile application for multiple camera control and precise object distance measurement and 3D position calculation using synchronized dual-camera triangulation.

Key Features:

Multi-Camera Control
- Master-slave camera synchronization for coordinated measurements
- Real-time camera parameter streaming between devices
- Support for both GPS-based and baseline-distance triangulation modes
- Automatic fallback when GPS accuracy is insufficient

Object Triangulation
- Calculate accurate object positions using geometric triangulation
- Measure horizontal distance, straight-line distance, and altitude
- Real-time triangulation with confidence scoring
- Supports distances from 10 meters to 10 kilometers
- Handles various camera geometries with automatic validation
- Rejects poor geometry configurations (parallel rays, behind camera)

Camera Management
- Live camera preview with orientation and sensor data overlay
- Real-time bearing, tilt, horizontal and vertical angle measurements
- Save and load camera parameters for repeated measurements
- View detailed camera metadata including GPS coordinates and timestamps
- Export captured photos with embedded EXIF metadata
- Screen wake lock to prevent interruptions during measurements

Technical Capabilities:
- Dual triangulation methods: GPS ray intersection and Law of Sines
- 3D position calculation with altitude estimation
- Support for elevation angles and vertical measurements
- Automatic geometry validation and error reporting
- Confidence-based result quality assessment

Use Cases:
- Surveying and distance measurement
- Object positioning and mapping
- Field research and data collection
- Educational demonstrations of triangulation principles
- Outdoor measurement applications where GPS may be unreliable

Perfect for professionals, researchers, and enthusiasts who need accurate distance measurements and spatial positioning using mobile devices.
