Reclassification

The AITracker system provides full results of the movement and classification of objects in the image. These results are stored in the format (.pickle) of the appropriate directory for the given configuration ConfigurationX, where X = 0, 1, 2, .... Thanks to this solution, the client can further work with the results by changing configurations and reclassifying all objects (trackers).

Offline processing - no additional fees

Reclassification is performed entirely offline on the user's computer. This process does not require an internet connection and does not incur any additional charges. All computations are done locally using the already collected tracking data.

When is reclassification needed?

You need to reclassify the measurement results when you modify:

• Cross-sections configuration - adding, removing, or repositioning measurement cross-sections

• Relations configuration - changing traffic relations between cross-sections (e.g., turns, through movements)

• Lane assignments - modifying lane definitions or lane-to-cross-section mappings

• Velocity thresholds - adjusting speed calculation parameters

After making any of these configuration changes, the existing tracker data must be recalculated to reflect the new settings.

What is recalculated?

During reclassification, the following classifiers are applied to each tracker:

Classifier	Description
CargoOcclusion	Detects cargo occlusion situations in vehicle tracking
CrossSectionPerspectivePolation	Calculates cross-section crossings with perspective correction
LanesFrechet	Assigns trackers to lanes using Fréchet distance algorithm
VelocityCrossings	Computes velocity based on cross-section crossings

Processing time

The reclassification process itself is time-consuming and may take several minutes (especially for measurements of several dozen objects). One by one, each result .pickle file will be loaded into memory and counted with the current configuration.

After reclassification

Once the reclassification process is complete, you can:

• Generate new reports - create updated traffic reports reflecting the new configuration

• Export data - export the recalculated results to various formats (CSV, Excel, etc.)

• Analyze statistics - view updated statistics and traffic flow data

Attention! Running the reclassification process automatically saves the entire configuration.
