Low altitude videos - the angle of incidence up to 45 degrees
For fixed camera records - no camera movement during the recording
Resolution: 1280×720 or more
Bitrate: 5 Mb/s or more
Framerate: 25 or more
Min. traffic object size: 32pixels in one dimension
Continuous video without cuts
We also recommend minimizing occlusions in the view on the scene in order to maximize the traffic analysis accuracy. It is useful for the input video to be as stable as possible with the area of the interest kept in the view throughout the whole video capture process to prevent misleading gate counting - since the video is not georegistered.

Drone videos - angle of incidence from 0 to 45 degrees
For oblique angles with distances shorter than 120 meters, FULL HD (1920x1200) resolution will be sufficient, but it's better to use a higher resolution (2k/4k)
For oblique angles with distances of 120 to 300 meters, use 4K video resolution
Record your video with 25 FPS and with standard bitrate (approx. 20 Mbit/s)
The system is robust against short occlusions
The recommended size of objects in the image is between 32x32 pixels to 150x150 pixels in the whole monitored area within the intersection
By following these rules you will get suitable videos for automatic processing to extract super-accurate data for your traffic study. Before the final recording, we recommend to carry out a test flight or make a few sample recordings in order to get acquainted with the basic principles. If you have any questions, do not hesitate to contact us.
