In a Nutshell

Turn videos into data.

OTVision, is a collection of algorithms to generate trajectories of road users in traffic videos. Most of the algorithms have been developed in previous open source projects. We modify and link them to a working pipeline.

Key features:

• Automated video analysis
• Detection using neural networks
• Can be used without programming knowledge
• Result: Trajectories in image and world coordinates
• Necessary: Windows computer with powerful graphics card (approx. 2.500 €)

Pipeline of algorithms:

• Conversion of h264 video files to other formats (ffmpeg)
• Detection (joint localization and classification) of road users in single frames (YOLOv5 by Jocher/Ultralytics)
• Tracking of detected road users between single frames (IOU-Tracker by Bochinski et al.)
• Correction of trajectories for lens distortion (OpenCV-Library)
• Transformation of trajectories to world coordinates (OpenCV-Library)
