Privacy-preserving area monitoring with 3D cameras

GNS Engineering Team 1 min read

Cameras in public spaces raise legitimate privacy concerns. GNS Technology developed a 3D camera monitoring solution that solves this problem by design: it captures depth maps using reflected light instead of recording optical images.

The technology

Using reflected light, the camera extracts a depth map of objects for analysis. Because no optical image is captured or recorded — only the depth map — the solution is privacy-clean while still enabling powerful analytics.

Key advantages

  • Designed for outdoor environments
  • No optical image captured or recorded; only depth maps, giving privacy-clean solutions
  • Lower cost than radar-based solutions
  • Distinguishes object types: vehicles, people counting, types of obstruction
  • Covers over 60 × 60 square metres with less than 10% dimension error
  • Measures the speed and size of small packages and moving objects such as vehicles and trolleys
  • In measurement mode, accurately measures package dimensions from 10 cm to 900 cm and extracts a 3D model within one second

Applications

  • City management
  • Housing and population monitoring
  • Transport and road traffic status monitoring
  • Passenger counting in local facilities
