Tokyo will be using 3D cameras to take 3D mugshots. via geek wire
Japan’s largest and capital city Tokyo is the first to roll out the 3D cameras, with all 102 police stations located there getting a 3D camera installed in April. When a mugshot is taken, the person’s face is lit with striped lighting and the camera captures data from three different directions.
The captured data is much more useful when trying to identify an individual in future. Criminal activity is often caught on camera and the police use CCTV footage to try and figure out who is committing a crime. But there’s no guarantee the criminal will look in the direction of the available cameras. However, with 3D data on file, it will be much easier to identify individuals given only partial facial shots.
