Set-up Intersection Insights

How to succeed in getting the information for crossings or roundabouts as well as vehicle movements from Origin (Entry) to Destination (Exit).

You want to know the flow of your intersections, SWARM Perception platform is providing the solution to get the number of vehicles starting in an origin zone and ending up in a destination zone per vehicle type (Classes).

What data can be generated?

For this use case, SWARM software is providing you with any data needed for Origin Destination Zones - The number of vehicles from one zone to another including classification according to BAST/TLS standards can be covered.

What needs to be considered for a successful analysis?

Find detailed information about camera requirements/settings as well as camera positioning in the table below.

Recommended

Pixels per Meter (PPM)

Pixels Per Meter is a measurement used to define the amount of potential image detail that a camera offers at a given distance.

> 30 PPM for object classes car, truck

> 60 PPM for object classes person, bicycle, motorbike

Using the camera parameters defined below ensures to achieve the minimum required PPM value)

Tip: Use the Axis lens calculator or generic lens calculator.

Camera video resolution

1280×720 pixel

Camera video protocol/codec

RTSP/H264

Camera Focal Length

2.8mm-12mm

Camera mounting - distance to object center

Object classes car, truck

5-30 meters (2,8mm focal length)

35-100 meters (12mm focal length)

Object classes person, bicycle, scooter

3-12 meters (2,8mm focal length)

25-50 meters (12mm focal length)

Camera mounting height

Up to 10 meters

Note: Higher mounting is preferred to minimize occlusions from larger objects like trucks

Camera mounting - vertical angle to the object

<50°

Note: setting the correct distance to vehicle and camera mounting height should result in the correct vertical angle to the vehicle

0° - 360°
