Multifaceted Policy Evaluation and Design Support in 3D Space

This technology allows for the real-time reproduction of people and objects in a three-dimensional digital space, enabling the evaluation of policies from various perspectives. This allows for multifaceted analysis of factors such as congestion and safety, making effective policy evaluation and design possible.

Challenges

  • To address social issues, it is necessary to evaluate the effectiveness of measures in advance and ensure their safety and efficiency.
  • With traditional technology, there are many technical constraints on reproducing the movements of people and vehicles in three-dimensional space in real-time, making it difficult to easily assess from individual perspectives.

Solutions

  • We have developed technology that allows real-time reproduction of moving objects, such as cars and people, in a three-dimensional digital space from a single conventional monocular camera.
  • It estimates the position and three-dimensional shape of objects from two-dimensional video, and maps them accurately onto a three-dimensional spatial model that replicates stationary objects.
  • This enables the evaluation of measures considering individual perspectives, achieving a more realistic digital twin.

Advantages

  • By using data from already installed surveillance cameras, it is possible to generate highly accurate 3D digital twins at a low implementation cost.
  • Different perspectives, such as those of pedestrians, drivers, and security guards, can be used to review the environment, allowing for a multi-faceted evaluation of specific measures.
  • In addition to macro indicators such as CO2 emissions, considering micro indicators like safety from an individual's perspective enables a more comprehensive policy design.

Demonstration

  • You can watch a demonstration of how to build a 3D digital twin and its various applications.

Provision Plan

  • Fujitsu aim to commercialize this technology by verifying its usefulness not only in transportation but also in smart cities and traffic safety, with the aim of expanding its scope of application.
