Visualize flow lines in a wide area and in real time using laser sensors

The flow-based object tracking solution is a solution to measure and visualize the flow lines of people and objects in real time by laser sensor system.
By linking the trajectory data with the center facility, it can display the trajectory data in real time even from a remote place and create a report.

  • Visualize the flow of people and objects
  • Flexibility in measuring area
  • Advantages by laser sensor

Overview of System

  • Detect and visualize people / objects with high precision and real time with laser sensors.
  • Always tracking allows you to grasp the position, movement (direction / speed) and trajectory in the area.
  • The measurement result is accumulated in the control PC as coordinate data, and data can be analyzed and reported.

Measurement

Realize stable and accurate flow line measurement by laser radar system

Adopt the laser radar system realized by the distance measuring technology using class 1 laser and the sensing technology cultivated over many years in-house. Flow line measurement with high precision and consideration of privacy is possible.

Principle of measurement

Principle of measurement

The laser sensor itself emits infrared light and receives the reflected light returned from the object to detect and measure the distance to the object, the traveling direction, the moving speed, etc.

Measurement technology for a wide area

Measurement technology for a wide area

Wide range measurement is possible by joining multiple sensors overlapping and straddling by prediction technology.

People / objects recognition algorithm

People / objects recognition algorithm

Since information on the reflected light from the sensor is recognized as a person or object by its own algorithm, the measurement target does not have to hold any device.

Analyze / report accumulated data

In addition to measuring and displaying the movement of people and objects, it is also possible to analyze the trajectory data and provide it in a report format.
