Purdue professor develops 3D image transmission technology


A Purdue University professor has developed a technology for transporting 3D data through phones, the Indianapolis Business Journal reports. The system, dubbed Holostream by inventor Song Zhang, drastically reduces the size of 3D video without major quality degradation to enable transmission within current bandwidth limitations.

Zhang told the Journal that facial recognition is among the many possible applications for the technology, along with expanding the capabilities of 3D printer manufacturing, and medical uses. It can also improve the quality of teleconferencing and telepresence applications already leveraging real-time 3D data delivery.

“To our knowledge, this system is the first of its kind that can deliver dense and accurate 3D video content in real time across standard wireless networks to remote mobile devices such as smartphones and tablets,” said Zhang, an associate professor in Purdue University’s School of Mechanical Engineering.

Zhang’s research has been assisted by Purdue students and funded by the National Science Foundation, and a patent application filed through the Purdue Research Foundation’s Office of Technology Commercialization is pending.
