How to record the video for DFS Light
Give it 5 minutes and read carefully how to set up the parameters on your camera and record the video properly. The better the input = the better the results!
The DataFromSky Light can process data from any video input such as static/handheld consumer camera video recording or video capture from an existing video infrastructure (i.e. surveillance cameras). For the best traffic analysis results we recommend the following input video parameters:
- resolution: 1280×720 or more
- bitrate: 5 Mb/s or more
- framerate: 25 or more
- min. traffic object size: 32px in one dimension
- continuous video without cuts
- no camera movement
We also recommend minimizing occlusions in the view on the scene in order to maximize the traffic analysis accuracy. For the post process traffic analysis in the DataFromSky Viewer Light software, 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 a misleading gate counting since the video is not georegistered.
Example of the configuration best suitable for DFS LIGHT analysis :
- the height of the camera: 10m
- resolution: HD
- optics FOV: 90°
- the angle of view the camera has with the ground: 45°
There can be different configuration, the parameters affect each other, except for the last one — it should always be in the range of 30–60 °!
