How to Get Started with TinCam: Setup & Best PracticesTinCam is a compact, efficient camera solution widely used for aerial mapping, inspection, and research projects. This guide walks you through everything you need to get TinCam up and running — from unboxing and hardware setup to calibration, software integration, and practical best practices for reliable data collection.
What is TinCam and who should use it
TinCam is a lightweight, high-resolution imaging module designed for integration with drones, tripods, or stationary mounts. It’s aimed at surveyors, drone pilots, researchers, and hobbyists who need accurate, repeatable imagery for photogrammetry, inspection, or monitoring tasks. TinCam typically provides features such as interchangeable lenses, GPS/IMU integration, and flexible exposure controls.
Unboxing and initial inspection
- Inspect the package for physical damage.
- Confirm contents: camera body, lens(es), mounting hardware, USB/data cable, quick-start guide, and any included SD card.
- Check serial number and firmware version (often printed on the box or camera body) and note them for support.
Hardware setup
- Mounting
- Attach TinCam to your drone gimbal or chosen mount using the supplied screws or a compatible adapter. Ensure the camera is secure and vibration-damped if possible.
- Power
- Connect to the recommended power source. Many setups use the drone’s power bus; others rely on an internal battery. Verify voltage/current specifications in the manual.
- Storage
- Insert a high-speed SD card (UHS-I or better recommended). Format the card in-camera before first use to avoid file system issues.
- Lens and focus
- Install the appropriate lens for your use case (wide-angle for broader coverage; narrower lenses for detail). Manually focus or use the camera’s autofocus if available; for mapping, lock focus to avoid shifts between images.
- GPS/IMU and external sensors
- If using an external GPS/IMU, connect and verify communications. Proper time-sync between camera and IMU/GPS improves geotagging accuracy.
Firmware and software installation
- Check for the latest firmware on the manufacturer’s site and apply updates following provided instructions. Firmware updates often fix bugs and add features.
- Install the desktop or mobile app that accompanies TinCam for configuration and image transfer.
- If you use photogrammetry software (Pix4D, Agisoft Metashape, OpenDroneMap), ensure TinCam’s image format and metadata are supported.
Camera configuration for mapping
- Image format
- Use RAW (if available) for maximum post-processing flexibility; otherwise use high-quality JPEG.
- Resolution and compression
- Set the highest practical resolution. Avoid heavy compression for mapping tasks.
- Shutter speed and aperture
- Aim for a shutter speed that prevents motion blur (rule of thumb: shutter speed >= 1 / (ground speed * focal length factor)). Use aperture to balance sharpness and exposure.
- White balance
- Set a fixed white balance (e.g., daylight) rather than auto, to keep colors consistent across images.
- Intervalometer / trigger settings
- Configure interval or trigger settings to achieve 60–80% forward overlap and 30–60% side overlap, depending on terrain complexity and altitude.
Pre-flight checklist (for drone users)
- Batteries charged for drone and camera.
- SD card formatted and has sufficient space.
- GPS lock and IMU calibration complete.
- Camera securely mounted and lens clean.
- Exposure settings configured; test shots taken.
- No-fly zones and local regulations checked.
Best practices for data capture
- Overlap and sidelap: For photogrammetry, more overlap improves reconstruction — typical targets: 70% forward overlap, 60% side overlap for detailed maps.
- Flight altitude: Choose altitude to meet desired ground sample distance (GSD). Use the formula GSD = (sensor_pixel_size × flight_height) / focal_length to estimate.
- Consistent exposure: Use manual settings when possible to avoid exposure shifts between frames.
- Sun angle and shadows: Fly when sun is high to minimize long shadows; avoid mid-afternoon when thermal turbulence may affect stability.
- Ground Control Points (GCPs): Use precisely surveyed GCPs to improve absolute geolocation accuracy, especially for surveying-grade outputs.
- Redundancy: Capture extra passes or overlapping images as a hedge against data loss from motion blur or dropped frames.
Data transfer and backup
- Transfer images to a laptop or external drive immediately after the flight.
- Keep at least two copies (original SD card + primary backup) before processing.
- Use checksums (e.g., md5) for large datasets to verify integrity after transfer.
Post-processing workflow
- Organize images into folders labeled by date/site.
- Convert RAW to 16-bit TIFF if needed for photogrammetry.
- Import to your photogrammetry software:
- Check image alignment and camera model settings.
- Add GCPs and set coordinate system if available.
- Run dense cloud generation, mesh, and ortho/map export steps.
- Validate outputs against GCPs or known measurements.
Troubleshooting common problems
- Blurry images: Increase shutter speed, check gimbal stabilization, ensure lens focus is locked.
- Poor geotagging: Verify GPS timestamps and camera-IMU sync; consider using external logger or post-process kinematic (PPK) correction.
- Inconsistent exposures: Disable auto-exposure and use fixed settings.
- Missing frames: Check SD card health; use high-quality cards and format in-camera.
Maintenance and care
- Keep lenses clean with lens cloth and blower; avoid touching the glass.
- Store camera and batteries at recommended temperatures.
- Periodically check and update firmware.
- Inspect mounts and screws for wear before each mission.
Example mission plan (survey field 200 × 200 m)
- Desired GSD: 2.5 cm/px → choose flight altitude accordingly using sensor/focal parameters.
- Frontlap: 75%; sidelap: 65%.
- Flight speed: set to maintain required shutter speed (no motion blur).
- Number of flight lines: calculate from swath width at chosen altitude; plan 4–6 lines for full coverage.
- Include 5–7 well-distributed GCPs for georeferencing.
Advanced tips
- Use RAW+JPEG to speed previewing while retaining RAW for processing.
- For high-accuracy surveys, use PPK/RTK workflows with precise base station data.
- Time-of-day planning: golden hours produce pleasing photos but may create long shadows — choose based on priorities (visuals vs. even illumination).
- Automate repetitive processing with scripts or batch workflows in your photogrammetry software.
Final notes
Getting high-quality results with TinCam combines correct hardware setup, disciplined pre-flight checks, consistent camera settings, and a careful post-processing workflow. Start with a small test area to validate settings before scaling to larger projects.
