Our Sensory Products


The 3D PassCount is an innovative embedded sensory solution with the operating principle based on Time of Flight (ToF) technique by using 19200 pixels (e.g 160x120 pixel resolution). The 90 degree field of view and up to 40 FPS perfectly matches demand of on-board vehicle deployment. The sensor has two InfraRed LEDs and the modulated IR waves are directed to the target objects need to be detected and the sensor detects the reflected IR component. By measuring the phase difference between the radiated and reflected IR waves the distance to the object can be calculated.

Thus the 3D PassCount sensor transforms the ToF positional data into a rich 3D image in real-time, including a grey-scale map, which is easily accessible for software analysis. The algorithm using full human body depth image to analyze passing through peoples height, head, shape and directions of motions.

Depth sensing is based upon standardized CMOS technology. The soul of whole sensor system is a dual core embedded Digital Signal Processor (DSP), where Core A handles depth image, and Core B host whole image processing application. Thanks to this as image processing is done already in the sensor.


High Counting Accuracy

Thanks to high resolution,
high FOV and sufficient FPS of 3D PassCount
sensors and well tested and proven image
processing technology subject to any lighting
and environmental conditions and regardless
of door height and width and passenger crowds,
independent of direction of motion of passengers.
It works in total darkness and sunshine.

Easy Installation and Compact Design

The footprint of sensor is only 104 x 63 x 45 mm (L x W x H)
and with pre-installable brackets installation time is shortened.
Not to speak about the fact that in case of WiFi solution no
cabling is needed, only plug into 24 DC power supply of sensors.
Flush mount version of enclosure is also available upon request.
Easy installation is also enhanced by user-friendly software
where parametrization could be even done through cloud as
all devices are accessible remotely.

Robustness and Reliable Design

3D printed enclosures or aluminium
alloys with IP65 environmental protection class,
with extended temperature - 40 to + 85°C range of
operation of all hardware components and with low power
consumption makes the 3D PassCount sensor ideal
for any types of transport or commercial applications.

High Reliability

Low Life Cycle Costs are ensured by using Unix/Linux
operating software and on-board diagnostic system
in place, where error messages and warnings are
stored in remote data base system in the cloud or
dedicated server of PTOs, operators. MTBF of sensors
is over 70.000,- hours!

On-Board Units (OBU) are developed as spin off product of complex passenger counting systems, where OBU-s are handling wireless data communication, door handling and GPS/Glonass based navigation. We have complex ARM based OBUs and also cheap MCU based solutions based on Microchip. Our OBUs are scalable, from simple data collection function up to GNSS OBU with 3G, but GPRS/EDGE GSM communication is also supported. Moreover our OBUs are also WiFi and/or Bluetooth 4.0 enabled depending on applications and user needs.

Typical application areas

Primarily used in public transportation as part of PassCount system, but can be deployed in any automotive areas, where industrial grade (-40 C .. 85 C) conditions are needed to be meet. Our solutions are customizable.

Roadmap of product development
