• Abstract: The Bureau d'Enqu{\^e}tes et d'Analyses pour la S{\'e}curit{\'e} de l'Aviation Civile (BEA) has to analyze accident videos from on-board or ground cameras involving all types of aircraft. Until now, this analysis has been manual and time-consuming. The aim of this study is to identify the applications of photogrammetry and to automate the extraction of 4D trajectories from these videos. Taking into account all potential flight configurations, photogrammetric algorithms are being developed on the basis of IGN's MicMac software and tested in the field. The results of these automated processes are intended to replace flight data from recorders such as FDRs or CVRs, which are sometimes missing. The information of interest to the BEA includes: three-dimensional position with the associated time component, the orientations of the aircraft's three axes (pitch, roll and yaw navigation angles) and average speeds (including rate of climb).

  We propose a 3D data augmentation approach termed Drive-3DAug, aiming at augmenting the driving scenes on camera in the 3D space. We first utilize Neural Radiance Field (NeRF) to reconstruct the 3D models of background and foreground objects. Then, augmented driving scenes can be obtained by placing the 3D objects with adapted location and orientation at the pre-defined valid region of backgrounds.

• Vehicle-Human Interactive Behaviors in Emergency: Data Extraction from Traffic Accident Videos [0.0]
  Currently, studying the vehicle-human interactive behavior in the emergency needs a large amount of datasets in the actual emergent situations that are almost unavailable. This paper provides a new yet convenient way to extract the interactive behavior data (i.e., the trajectories of vehicles and humans) from actual accident videos. The main challenge for data extraction from real-time accident video lies in the fact that the recording cameras are un-calibrated and the angles of surveillance are unknown.
