Tokyo's Metropolitan Police Department has said it will start taking 3-D mugshots of all suspects in custody for a database, to improve its facial matching capabilities.The MPD will place a 3-D camera in all of its 102 police stations from April, with its identification section to manage all the 3-D mugshots taken with those cameras, reports the Asahi Shimbun.”We can identify the suspects more quickly and accurately, our arrest rate is expected to become greater,” said a high-ranking investigation officer of the MPD.The police officials stressed that a 3-D image can be match much easier with CCTV footage because the 3D images can be adjusted to match the angle of security camera footage, which is often shot from above, rather than at face height. The MPD introduced the 3-D camera only for its research institute on scientific investigation in 2001.
