The configuration of the solution can be managed centrally in SWARM Control Center. Below, you can see how the Entry/Exit parking with license plate detection needs to be configured for optimal results.

In order to start your configuration, take care that you have configured your camera and data configuration.

How to place the configuration type?

To receive the best accuracy in counting including the classification, the CL should be placed approx. in the middle of the video frame so that vehicles from both directions are seen long enough for good detection and classification.

Consider that the IN/OUT direction of the counting line is important as it is relevant for the calculation of the utilization. (IN = Entry to parking, OUT = Exit of parking).

Visualize data

You can visualize data via Data Analytics in different widgets.

Scenario

In our Parking Scenario section, you can find more details about the possible Widgets to be created in the Parking Scenario Dashboards.

pageParking Scenario

Example

You are able to visualize the data for any Entry/Exit you have configured with the Counting Lines. So you are able to see the number of vehicles with their classes/subclasses that entered or left your parking spot, either aggregated over several Entry/Exits or separately per Entry/Exit. We deliver the following two standard widgets Current & Historic Parking Utilization out of the box when creating a Parking Scenario Dashboard

Retrieve your data

If you need your data for further local analysis, you have the option to export the data of any created widget as csv file for further processing in Excel.

If you would like to integrate the data in your IT environment, you can use the API. In Data Analytics, you will find a description of the Request to use for retrieving the data of each widget.
