«Incidents» Section#
The section is used to display all incidents from incoming video stream images. Receiving and displaying incidents is performed with minimal delays in a mode close to real time.
The general view of the «Incidents» section (Figure 24).
By default, the last 10 incidents are displayed on the page. To view previous incidents, navigate to other pages. Page navigation is done using the pagination buttons at the bottom of the page (Figure 25).
The number of incidents per page can be changed using the dropdown list next to the pagination buttons.
When navigating between incidents pages, new incidents will not be displayed in the table. This is to prevent the rows from «moving» during incidents table viewing. Once the user returns to the first page, all new incidents are automatically loaded.
The description of the incidents table content is provided in Table 7.

A vehicle can have multiple LP crops. If a new result is «similar» to an already found number (character match above the threshold), it replaces the existing one as a more accurate result. If «not similar» (different character sequence/match below the heuristic threshold), the system considers it a different number, records it as a separate line, and shows it as a separate crop. Therefore, a vehicle may have multiple LP entries/crops.
The numbers next to each attribute represent the recognition quality of that attribute. The rating is determined within the range from 0 to 1; the closer the value is to 1, the more accurate the recognition result is.
Clicking on any frame opens extended frame information. For Track Frames, a pop-up window appears (Figure 30), containing:
- Frame ID – frame identifier
- Time – incident detection date and time
- Type – frame type
- Recognition Zones – checkboxes allow showing the recognition zones on the frame
- Frame with the object - the detected object is highlighted with a BBox
Incidents Filter#
CARS_Analytics UI allows users to filter incidents to limit the display of the incident list on the screen.
The filters are located on the right side of the page and are open by default. You can hide the filters by clicking on 
.
With the filters, the user can quickly find an incident. By default, filters are off, and all new incidents are automatically loaded into the table.
Incidents filtering can be done by one or more parameters (Figure 31).
All filters except for Date, Incident ID, Number of Axles, LP Symbols, Image Search, and Auto-fill filters support multiple selections. To cancel the filter selection, click on 
or the «Reset» button.
The filters for Scenario, Incident Type, Cameras, Lists, Emergency Services, Special Transport, Public Transport, Brands, Models, Vehicle Types, Colors, and Vehicle Registration Country are presented as dropdown lists. These filters support keyboard input for searching list items. The number of items in the list will change dynamically as characters are entered.
For all filters except Date, Scenario, Incident Type, Camera, IncidentID, and Lists, precision settings are available. To adjust this value, click on the «Score Threshold» 
button to the right of the filter field.
When clicking on «Score Threshold»
0.000to1.000. If values below 0 or above 1 are entered, an error will appear. Also, if more than three decimal places are entered, a warning will appear showing the two closest acceptable values.
By default, all filters, except Date, Number of Axles, and LP Symbols, have an icon 
next to the field, which means the filter will be applied to the selected value. When clicked, the icon will change to 
, and the filter will be applied excluding the selected value (i.e., for all values except the one specified in the field).
The description of each filter is provided in Table 9.

The user needs to set one filter or a combination of filters and click the «Apply» button for the settings to be applied.
The list of supported vehicle brands and models depends on the selected version of the classifier for recognition (for more information, see «LUNA CARS_API. Administration manual»). When selecting the latest version of the classifier, over 160 models and 1700 brands are supported in the system.
Vehicle brand and model recognition in the system is done by the vehicle body appearance.
Vehicles of different brands and models, but with similar body appearances, are categorized under the most common brand and model in the region. For example, ZAZ Sens, ZAZ Lanos, ZAZ Chance, Daewoo Sens, Daewoo Lanos, Chevrolet Lanos, ZAZ Lanos Furgon have similar body appearances, and LUNA CARS identifies these models as Chevrolet Lanos. When the filters are set to «Daewoo» and «Sens», the filtering results will include any vehicle from the above-mentioned brands and models, but «Chevrolet» and «Lanos» will be displayed in the «Brand» and «Model» fields.
A complete list of related makes and models is provided in the «LUNA CARS_API. Administration Manual».
Clicking the icon 
to the left of the «Filters» heading opens the report generation settings window. The report will include all events matching the applied filters with the settings taken into account. Report creation happens as part of a background task. Working with tasks and applying export settings is described in section Tasks.
To reset the entered values, click the «Reset» button or 
next to the filters icon to the right of the «Filters» header.
