3-D camera systems to be installed at all MPD stations

The Metropolitan Police Department (MPD) plans to install 3-D camera systems at all of its stations from the coming fiscal year for taking 3-D images of arrested suspects.

    The system is expected to provide a better means of identifying suspects on security footage than can be done currently. According to the MPD, it will be the first time for police authorities anywhere in the country to install the systems at all stations under their jurisdiction. Such cameras are already installed at some prefectural police headquarters around Japan.

    The systems measure about 100 centimeters wide by 50 centimeters deep by 130 centimeters tall. A suspect sits in a chair and is photographed from the front and sides. The curves of their face are read by the system and saved as a 3-D representation of their face.

    Currently, four types of photographs of arrested suspects are taken, including from the front, diagonally, and a view of the whole body. However, there have been many cases where comparisons between these photos and security footage have been difficult. The 3-D images taken with the new system can be adjusted to the same angle and size as in security footage, and is said to allow highly accurate identification.
