The measuring principle of IRMA Matrix is based on a matrix of 500 pixels (sensor array) with which the sensor gauges the distance to the object and detects it three-dimensionally. This is made possible by the so-called time-of-flight (TOF) technique. This technique uses the phase difference between the transmitted and the decoded signals from the sensor; so the distance to the object is calculated from the run-time of the signal. In this way the presence and movement of persons within the visual field can be determined with very high accuracy.
The high stop accuracy of IRMA Matrix meets strictest standards for automatic passenger counting. This allows new applications in public transport, e. g. real-time capture of passenger load.
The installation costs are minimised thanks to the high integration of the sensor: IRMA Matrix is characterised by its direct connection to Ethernet or CAN with no further system component. In addition, you need only one IRMA Matrix sensor per standard door.
