Axis supports new developments in state-of-the-art image processing technology at University of Tokyo Graduate School

Basic research is being performed on technology that features Open Angle ViewImage shown as a real-time image using a Multiple Camera System

"Because 64 camera images will be processed as a real-time image, the system’s loading equipment needs to accommodate more than one function. The network camera balances this need satisfactorily at a reasonable cost."Associate Professor Takeshi Naemura, Specialist in Electronic Information and Communication, University of Tokyo Graduate School.

Mission

Since 1998, the Naemura Laboratory at the Research Department in the Department of Information & Communication Engineering at the University of Tokyo Graduate School, has been developing a Multiple Camera System in which multiple cameras are lined up in an “alleyway” style. The first system developed was comprised of 16 surveillance cameras (4 cameras vertically x 4 cameras horizontally) that gathered analog video signals into one workstation. The video transmission zone of this system was limited and would not permit any further increase in the number of cameras used. Thus the important issue was faced of how to more efficiently build the part of the system that inputs data to the calculator unit in order to build a Multiple Camera System consisting of additional cameras.

Solution

The demand for a high-quality product in performing the research found an answer in Axis network cameras, which perform Simultaneous Motion Imaging shown as a real-time image.

The network camera connects to the IP network, and is able to directly compress and process the visual data of an image. Consequently, even in the case where the zone transmission is limited, it is possible to compress and efficiently transmit massive amounts of data. Furthermore, by sending a simple command from the calculator unit, in turn made possible by the HTTP server function, the positioning of the camera and the capture of an image are facilitated. The major reason for adopting Axis network cameras was because of their excellent features, as well as their cost-effectiveness.

Result

In adopting the Axis network cameras, the lab has been able to design the equipment body unit into a more compact form, thereby making the system mobile. As a result, the laboratory research team feels that the performance of the research has progressed rapidly.
