Description :
This dataset contains sequences of pedestrian navigation in an urban environment carried out in the city of Dijon, France, in a variety of representative environments.
Synchronised colour and depth images, as well as GPS and inertial positioning data, are recorded. The colour images are annotated to reference and locate elements of significance to pedestrians (cars, pavements, signs, etc.).
This dataset was produced as part of a project to develop a mobility assistance system for the visually impaired using sound substitution. For each sequence, a sound file corresponding to a substitution method is proposed.

computer science, artificial intelligence (engineering science), computer science, software engineering (engineering science), engineering, industrial (engineering science)

General metadata

Data acquisition date : from 28 Mar 2023 ongoing
Data acquisition methods :
  • Observational data :
    To record this data, a person equipped with a recording system travelled around the city of Dijon. The system consisted of an Intel Realsense D435 RGB-D camera (rvb-d), an Adafruit BNO055 Inertial Measurement Unit (IMU-100Hz) sensor and a GPS antenna (10Hz). Each sensor had a dedicated thread operating independently of the others to ensure synchronisation between the rate of data acquisition and the recording process.
    A synthetic sequence modelling the Place Darcy in Dijon (produced from a LIDAR scan) was added to enrich the dataset.
    The image-sound conversion generates spatialised sounds whose frequency depends on elevation (from 250 Hz to 1492 Hz), which is convolved with the HRTFs in the CIPIC database to obtain a stereophonic sound spatialised in azimuth and elevation.
