Criterion 1: Camera View

1. Distance from monitored objects

The footage can be taken from 50 to as high as 250 meters above the ground. This means that objects directly under the drone will be this far, however if the camera is not angled directly downwards, this distance can be much greater for objects further away. The general rule of thumb is - the harder the scene (smaller objects in the distance), the harder it is to gather accurate reliable data.

2. Camera tilt

Top-down view is best for higher altitude footage and highway/road traffic focus, whilst angled camera on low altitude flights will allow for better detection of smaller objects like pedestrians, bicycles and motorcycles.

Criterion 2: Video Quality and Light Conditions

1. Resolution

The input resolution should be UHD/4k (3840 × 2160/4096 × 3112) as this allows even the smaller objects to be recognized reliably from higher altitudes.

2. Scene lighting 

Poorly lit scenes, deep shadows or huge Illumination changes all make it way harder to detect objects consistently. Take a look at how "visible" a dark colored car becomes, once it enters a deep shadow.

Criterion 3: Video framerate (FPS) and shutter speed

Here, the same rules apply as described in our Standard processing guidelines.
