Study Notes
Camera Setup and Flight Preparation
- Use DJI Go 4 for orbit flying.
- Adjust camera settings:
- File format set to JPEG.
- White balance configured for sunny conditions.
- Photo style set to time shot with a 2-second interval.
- Ensure histogram and file index mode are set to continuous for effective data acquisition.
Flight Execution
- Tilt camera to a 45° angle using the blue circle indicator next to the shutter button; this is integral for capturing 3D data.
- Flying at a higher elevation (recommended at 150 ft) reduces data acquisition time.
- For orbital flying:
- First, move the roll stick to start the circular motion.
- Use the yaw stick in the opposite direction to maintain orbit.
- Initiate photo capture by pressing the shutter button.
Data Capture Strategy
- Aim for 20-30% of the building to appear in the frame for better context in images.
- Maintain battery voltage around 3.6 volts for optimal performance and landing safety.
- Take note of the phone's temperature; avoid overheating by keeping it in the shade.
Recap of Acquisition Process
- Camera setup included:
- Shutter priority set to 1/1000 sec.
- Photo mode set for capture every 2 seconds.
- After elevating to 150 ft, initiate the shutter to start capturing images.
- Perform one complete orbit around the building, capturing necessary data with specific overlaps (80% forward and 80% side).
Transition to Detailed Package
- For the detailed package, replace the battery and configure a double grid mission.
- The same elevation and overlap specifications apply to the detailed package.
- Reuse existing orbital data without the need for additional orbits.
- Set up mission parameters in the shade to conserve battery power prior to flight.
Camera Setup and Flight Preparation
- DJI Go 4 is utilized for executing orbit flying missions.
- Configure camera settings:
- File format is preset to JPEG for optimal image quality.
- White balance should be adjusted for sunny conditions to enhance color accuracy.
- Photo style is configured for time shots with a 2-second interval to capture sequential images.
- Ensure histogram and file index mode are on continuous to facilitate effective data collection.
Flight Execution
- Camera tilt should be set to a 45° angle, crucial for capturing comprehensive 3D data representations.
- Recommended flying altitude is 150 ft, which aids in reducing data acquisition time substantially.
- To initiate orbital flying:
- Roll stick movement commences circular motion around the target object.
- Use yaw stick in the opposite direction to maintain a balanced orbit.
- Capture photos by pressing the shutter button when ready.
Data Capture Strategy
- Ensure 20-30% of the building is featured in the frame for better contextual information in images.
- Maintain battery voltage around 3.6 volts to ensure optimal drone performance and safe landing.
- Monitor the phone’s temperature closely; avoid overheating by keeping it shaded during flight operations.
Recap of Acquisition Process
- Camera settings include:
- Shutter priority fixed at 1/1000 sec for crisp images.
- Photo mode is configured to take captures every 2 seconds.
- Upon reaching 150 ft altitude, initiate the shutter to begin the image capture.
- Complete one orbit around the building, ensuring 80% overlap in both forward and side directions for comprehensive data acquisition.
Transition to Detailed Package
- For detailed data packages, replace the drone's battery and set up a double grid mission.
- Maintain the same elevation (150 ft) and overlap requirements as with the initial data acquisition.
- Utilize existing orbital data without the necessity of additional orbiting.
- Set mission parameters in a shaded area to conserve battery life before commencing the flight.
