Symmetry Dimensions Inc., a software developer (registered in Delaware, US; hereinafter referred to as ‘SYMMETRY’; Shogo Numakura, CEO), engaged in the research and development of digital twins, has begun development on a demonstration for the optimization of building design work using AI and VR, and automation of infrastructure inspection by crack detection, prediction and visualization of concrete at at the Smart Innovation Lab provided by NIPPON TELEGRAPH AND TELEPHONE EAST CORPORATION (NTT East).

AI and VR make building design software easy for anyone to use

Unlike conventional 2D image recognition using deep learning, we've developed a process for 3D object recognition. By applying this to VR, the AI will be able to identify 3D objects and manipulate them within VR. Furthermore, by combining it with natural language processing*, we will work on the practical application of systems given inputs such as "Change the color of the chair to red" or "Make the front light brighter." which will allow anyone to easily confirm, correct, and propose 3D models and architectural designs viewed in VR by voice command.

Automated infrastructure inspection with AI and VR

High-resolution 2D images and 3D models are generated from images captured by drones. By applying deep learning to the scan data, we can automatically detect and predict cracks in concrete. Mapping photos and damage situations that were previously recorded separately for each damaged part to VR makes it possible to clearly see the damage. By doing so, we aim to realize automatic inspection of infrastructure and a drastic reduction in the number of work hours.

In the future, DVERSE will use deep learning to recognize and store 3D models, point cloud data, PoS data, and customer behavior data on servers in NTT East's telecommunications buildings and data centers.

*Using a computer to process the language that humans use on a daily basis. Examples include voice recognition with smart speakers.
