Traffic and Transportation (ITS)

Global shutter image sensors that support high-speed shutter and readout can be applied to identify license plates of vehicles traveling in high-traffic environments. Security camera image sensors are used as devices that can recognize license plates clearly, even in dark environments or environments with highly variable lighting conditions.

In observations conducted by fixed-point cameras to enforce traffic regulations, light can be reflected by vehicle windshields depending on the time period and angle, sometimes making it impossible to identify individuals in the vehicle. When installed appropriately, polarization image sensors make it possible to reduce or remove reflected light and detect the number of individuals in a vehicle.

Sony’s security camera image sensors, with their high performance in low-light environments and wide dynamic range, are applied in outdoor environments with strict illuminance conditions. They are used to grasp traffic volume, identify traffic congestion, detect traffic accidents or vehicles driving in the wrong direction, identify vehicle registrations, and various other applications.
