## Description

MultiCam - Multi-Camera Control System<br><br>An mobile application for multiple camera control and precise object distance measurement and 3D position calculation using synchronized dual-camera triangulation.<br><br>Key Features:<br><br>Multi-Camera Control<br>- Master-slave camera synchronization for coordinated measurements<br>- Real-time camera parameter streaming between devices<br>- Support for both GPS-based and baseline-distance triangulation modes<br>- Automatic fallback when GPS accuracy is insufficient<br><br>Object Triangulation<br>- Calculate accurate object positions using geometric triangulation<br>- Measure horizontal distance, straight-line distance, and altitude<br>- Real-time triangulation with confidence scoring<br>- Supports distances from 10 meters to 10 kilometers<br>- Handles various camera geometries with automatic validation<br>- Rejects poor geometry configurations (parallel rays, behind camera)<br><br>Camera Management<br>- Live camera preview with orientation and sensor data overlay<br>- Real-time bearing, tilt, horizontal and vertical angle measurements<br>- Save and load camera parameters for repeated measurements<br>- View detailed camera metadata including GPS coordinates and timestamps<br>- Export captured photos with embedded EXIF metadata<br>- Screen wake lock to prevent interruptions during measurements<br><br>Technical Capabilities:<br>- Dual triangulation methods: GPS ray intersection and Law of Sines<br>- 3D position calculation with altitude estimation<br>- Support for elevation angles and vertical measurements<br>- Automatic geometry validation and error reporting<br>- Confidence-based result quality assessment<br><br>Use Cases:<br>- Surveying and distance measurement<br>- Object positioning and mapping<br>- Field research and data collection<br>- Educational demonstrations of triangulation principles<br>- Outdoor measurement applications where GPS may be unreliable<br><br>Perfect for professionals, researchers, and enthusiasts who need accurate distance measurements and spatial positioning using mobile devices.
