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.
