Abstract:

The 3D Body Processing Industry Connections (3DBP IC) Working Group, an adjunct group of IEEE P3141, Standard for 3D Body Processing (3DBP) is a group that brings together diverse entities devoted to making recommendations for 3D body processing interoperability. In the past three years, 3D has continued making inroads in product development, but the Covid-19 pandemic has accelerated the utilization of on-line retail, increased the number of phone apps for scanning, and increased usage of 3D Apparel CAD software. 5G technology and improved camera optics have also become pervasive, enabling faster file transfers and better image quality. Individual body model storage has grown as the volume of scans has greatly increased. Privacy laws and regulations to protect personal identifiable information are becoming of greater importance.

The next question becomes "what makes sense for Retail?" Retail Use Case ranges from Ready to Wear (RTW) to Body Shape Categories (body shapes) to fully Bespoke Apparel, Footwear and Eyewear. These conditions may require different types of body scans. Body avatars may vary from complete body scan avatars to population data avatars, or modifiable body-shape models.

Interoperability of data is still an issue for 3D environments not only for the 3D body scans but for the "near body environment" as well as materials and wearables. Body scans may include a soft tissue layer to better model the interaction between garments and the digital or virtual body. Interest in 3D to solve the fit and size problems, as well as reduce returns, in retail has grown.

To understand what is next for Retail, the goal of common taxonomies for 3D environments becomes particularly important. How are the terms around 3D, Digital, Virtual, Fit, Twins, avatars defined for the Retail industry when the applications can range from AR to bespoke garments? Terms need to mean the same for consumers and the retailers so that points of view of consumers and retailers are in alignment.

New areas of the 3D Body Processing Environment are the definitions of the Digital (Virtual) Twin or Digital (Virtual) Clone and how these pertain to Retail in relation to the Internet of Things (IoT). In Retail, the Digital Twin real time data can include the addition of consumer purchases to the consumer's body avatar for better understanding of fit preferences.

An example of Interoperability research was the EU project "BodyPass", with the aim to introduce an API-ecosystem for cross-sectorial exchange of 3D personal data, useful in order to analyze and extract shape information from large samples of 3D data, while giving special attention to personal data privacy protection. Thus, highlighting that the direction of processing and exchange of 3D data must protect personal data, and on other side protect the derived data which could have commercial value such as associated clothes models, custom annotations, measurement models.

The remaining outstanding issues include alignment and interoperability of file formats and quality levels of scans required and a common taxonomy for the Retail environment. The start of art should assist with the outstanding issues.
