To put it in a nutshell, the better the input, the better the results! If you have clear and stable footage where you are happy to tell a bus from a van, then you probably need not read any further and just upload your footage to DFS Light. Do you want to know a bit more? We have a few recommendations for you to enjoy the best possible results from your setup.
The DataFromSky Light engine can process data from any video input such as static/handheld consumer camera or footage from an existing CCTV infrastructure. 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 fps or more
min.traffic object size: 32px in one dimension
continuous video without cuts
no camera movement
We also recommend minimizing occlusions in the scene. It is useful for the input video to be as stable as possible. Try to avoid vibrations, re-composition, or generally any movement of the camera during the whole video acquisition. If not a permanent installation, we recommend using a tripod or magic arm to provide a solid support to your camera. It is much more convenient for you as well.
Example of the configuration best suitable for DFS LIGHT analysis :
elevation of the camera: 10m
resolution: > HD
optics FOV: 90°
the angle between the imaging axis and the ground plane: 45°
Different configurations are acceptable as long as the basic requirements are fulfilled. The most important parameter is the incidence angle: it should always be in the range of 30–60 °.
