The Construction Documentation Challenge
Filming active construction sites presents unique aerial challenges that ground-based documentation simply cannot solve. You need comprehensive coverage of multi-story structures, real-time progress tracking, and footage that satisfies both project managers and marketing teams.
The Mini 5 Pro addresses these demands with a sensor suite specifically designed for cluttered environments. During a recent bridge construction project, the drone's omnidirectional sensors detected and navigated around a red-tailed hawk that swooped into frame—maintaining both the shot and the bird's safety without pilot intervention.
This guide breaks down exactly how to leverage every relevant feature for professional construction documentation.
Understanding Obstacle Avoidance in Complex Environments
How the Sensor Array Works
The Mini 5 Pro deploys eight vision sensors and two infrared sensors creating a protective bubble around the aircraft. This matters enormously when flying near:
- Partially completed steel frameworks
- Suspended scaffolding systems
- Tower cranes with moving loads
- Temporary fencing and safety barriers
- Dust clouds from active excavation
The system processes environmental data at 60fps, allowing split-second trajectory adjustments. Unlike earlier generations that simply stopped when detecting obstacles, the Mini 5 Pro calculates alternative flight paths in real-time.
Configuring Avoidance for Construction Sites
Default settings prioritize safety over shot completion. For professional construction work, adjust these parameters:
Obstacle Avoidance Behavior: Set to "Bypass" rather than "Brake" to maintain smooth footage while navigating around unexpected obstructions.
Minimum Distance Setting: Reduce to 0.5 meters for tight interior shots of unfinished structures. The standard 1.5-meter buffer wastes valuable proximity on controlled sites.
Downward Sensing Sensitivity: Increase by two levels when flying over uneven terrain with debris piles, excavated areas, or temporary material storage.
Pro Tip: Disable upward obstacle sensing when filming beneath crane arms or inside structures with overhead obstructions. The sensors can misinterpret stationary steel beams as collision threats, causing unnecessary flight interruptions.
Subject Tracking for Equipment and Personnel
ActiveTrack 6.0 Capabilities
Construction documentation often requires following specific subjects—excavators moving earth, concrete trucks approaching pour sites, or safety inspectors walking perimeters. ActiveTrack 6.0 handles these scenarios with predictive motion algorithms.
The system recognizes and tracks:
- Heavy machinery silhouettes
- High-visibility safety vests
- Vehicles entering and exiting sites
- Groups of workers moving together
Lock-on speed has improved to 0.3 seconds from subject selection, critical when capturing time-sensitive operations like crane lifts or concrete pours.
Tracking Configuration for Optimal Results
Set tracking mode based on your documentation needs:
Trace Mode: Drone follows behind the subject. Ideal for documenting equipment paths across sites.
Parallel Mode: Maintains lateral position. Perfect for capturing excavation progress along trenches or foundation lines.
Spotlight Mode: Drone position remains fixed while camera tracks subject. Use for overview shots showing worker movement patterns.
Expert Insight: When tracking personnel for safety documentation, enable "Group Recognition" in advanced settings. This prevents the system from losing lock when workers pass each other or temporarily cluster together.
QuickShots for Standardized Progress Documentation
Automating Consistent Footage
Project stakeholders expect comparable footage across weekly or monthly progress reports. QuickShots eliminates operator variation by executing identical flight patterns.
Dronie: Captures establishing shots showing site context. Program identical start and end points for each documentation session.
Circle: Orbits structures at consistent radius. Set 15-meter distance and 45-degree camera angle for multi-story buildings.
Helix: Combines orbit with altitude gain. Reveals vertical construction progress effectively.
Rocket: Straight vertical ascent. Documents floor-by-floor completion on high-rise projects.
Creating Custom QuickShot Sequences
The Mini 5 Pro allows waypoint-based custom patterns that replicate across sessions:
- Fly desired documentation path manually
- Save as waypoint mission
- Adjust speed and camera angles
- Execute identical mission weekly
This approach produces footage that overlays precisely in editing software, creating compelling before/after comparisons.
Hyperlapse for Long-Duration Projects
Time-Compression Techniques
Construction projects span months or years. Hyperlapse condenses this timeline into digestible visual narratives.
Free Mode: Manual flight path during capture. Best for complex sites requiring obstacle navigation.
Circle Mode: Automated orbit hyperlapse. Position center point on primary structure.
Course Lock Mode: Maintains heading while allowing lateral movement. Useful for documenting linear projects like roads or pipelines.
Waypoint Mode: Pre-programmed path executed over extended periods. Most consistent results for professional documentation.
Technical Settings for Construction Hyperlapse
Optimize these parameters for site conditions:
- Interval: 2-second minimum for active sites with equipment movement
- Duration: Calculate based on desired output length (300 photos produces approximately 10 seconds at 30fps)
- Speed: Keep under 5 m/s to prevent motion blur between frames
- Altitude: Maintain minimum 30 meters to minimize foreground movement distraction
D-Log Color Profile for Professional Delivery
Why Flat Color Profiles Matter
Construction documentation serves multiple audiences—engineers need detail visibility, marketing teams want cinematic appeal. D-Log captures maximum sensor information for flexible post-production.
The profile preserves:
- Shadow detail in excavated areas
- Highlight information on reflective materials
- Color accuracy across mixed lighting conditions
- Dynamic range for high-contrast scenes
D-Log Workflow Integration
Shooting D-Log requires specific post-production handling:
LUT Application: Apply DJI's official D-Log to Rec.709 LUT as starting point. Adjust saturation and contrast for final delivery requirements.
Exposure Compensation: Overexpose by +0.7 stops when shooting D-Log. The flat profile benefits from additional highlight information.
White Balance: Set manually rather than auto. Construction sites mix daylight, artificial lighting, and reflective surfaces that confuse automatic systems.

Common Mistakes to Avoid
Flying in Sport Mode Near Structures: Sport mode disables obstacle avoidance. One moment of inattention near scaffolding ends expensive equipment.
Ignoring Magnetic Interference: Rebar, steel structures, and heavy equipment create compass errors. Calibrate before each flight session and monitor compass warnings constantly.
Underestimating Dust Impact: Fine particulate from excavation and concrete work infiltrates motor bearings and sensor lenses. Clean thoroughly after every site visit.
Neglecting Airspace Coordination: Active construction sites near airports require specific authorizations. The sub-249g weight exempts many requirements but not controlled airspace restrictions.
Shooting Only Wide Angles: Detail shots of connections, finishes, and problem areas provide more value than endless establishing shots. Vary focal lengths throughout documentation sessions.
Forgetting Battery Temperature: Construction sites lack climate control. Batteries below 15°C reduce capacity significantly. Keep spares warm in vehicle between flights.
Frequently Asked Questions
Can the Mini 5 Pro fly inside partially completed structures?
Yes, with precautions. Disable GPS positioning and switch to ATTI mode for indoor flights where satellite signals reflect unpredictably off steel structures. Reduce obstacle avoidance sensitivity to prevent false positives from nearby walls. Maintain visual line of sight and consider using a spotter for complex interior spaces.
How does wind affect construction site filming?
The Mini 5 Pro handles winds up to 10.7 m/s (approximately 24 mph). Construction sites often create localized wind acceleration around structures and equipment. Monitor real-time wind readings in the app and avoid flying on building corners where gusts amplify. Morning flights typically offer calmer conditions than afternoon sessions.
What permits do I need for construction site drone documentation?
The sub-249g weight eliminates registration requirements in most jurisdictions and exempts many operational restrictions. However, you still need site owner permission, coordination with any nearby airports, and compliance with local ordinances. Some municipalities require notification for commercial operations regardless of aircraft weight. Check specific requirements for your operating area.
