Best Camera Angles and Setup for Vehicle Classification Studies
Vehicle classification studies are essential for traffic management, urban planning, and infrastructure development. However, the accuracy of data collected in these studies largely depends on the quality of video footage captured. And that starts with one crucial factor — the camera setup and angle. In this blog, we’ll explore the best practices for setting up cameras to ensure precise and reliable vehicle classification from video footage.
Why Camera Placement Matters
Incorrect camera placement can lead to vehicle occlusion, shadow distortion, poor visibility in low light, and difficulty in distinguishing vehicle classes. For instance, overlapping vehicles during peak traffic hours can result in misclassification, especially in mixed traffic conditions.
The right angle and height can dramatically improve the detection of vehicle size, shape, and type — leading to better classification whether you’re using manual observation or automated recognition software.
Ideal Camera Angles for Vehicle Classification
Overhead/Top-Down View
Best for: Intersections, roundabouts, and multi-lane roads.
Advantages: Reduces vehicle overlap and occlusion.
Tip: Position cameras on poles or overpasses at 5-8 meters height for a clear view.
Oblique/Diagonal View
Best for: Road segments, entrances/exits, or where overhead setup isn’t feasible.
Advantages: Offers perspective on length and width of vehicles.
Tip: Set at a 30-45° angle from the lane with sufficient elevation (3–5 meters).
Side Angle (Lateral)
Best for: Low-volume areas, vehicle length analysis.
Advantages: Helps in distinguishing between similar height vehicles like vans vs. trucks.
Tip: Avoid direct front/rear angles — they compress dimensions.
Technical Setup Tips for Better Results
Resolution: Use HD or Full HD cameras to capture vehicle details clearly.
Frame Rate: 25–30 fps is ideal for smooth tracking.
Lighting: Ensure proper lighting conditions or use IR-enabled cameras for night capture.
Avoid Glare & Shadows: Set the camera angle to minimize direct sunlight or headlight glare.
Stability and Weatherproofing
Long-duration studies require the cameras to remain stable. Use vibration-free mounts and weatherproof casings. Also, check camera orientation frequently during data collection, especially during windy or rainy conditions.
Examples of Ideal Setup Locations
Flyovers and pedestrian bridges (for top-down views).
Rooftops of nearby buildings.
Temporary poles installed on medians or road shoulders.
Conclusion
A poorly placed camera can derail an entire traffic study. Whether you’re collecting data for city planning or academic research, investing time in the correct camera setup pays off with cleaner, more reliable data.
