CARS_API#

Changes:

  • Removed outdated classifiers and plans to reduce API memory consumption, which decreased RAM usage.

The following classifiers were removed:

  • vehicle_emergency_type и vehicle_emergency_type_v3
  • vehicle_color
  • grz_uk_asia_recognition_v1
  • emirate_recognition_v1
  • rus_plate_recognition_v2
  • eu_cis_recognition_v2

CARS_Stream#

Changes:

  • Added a check for false positive vehicle detections when a person was mistakenly recognized as a vehicle. If the IOU value between human and vehicle detection exceeds the threshold, no vehicle track is created.

Configuration parameters:

  • STREAM_FP_VEHICLE_TRACK_DETECTION — if set to 1, enabled the logic for discarding false positive vehicle detections; if 0, disabled the logic;
  • STREAM_FP_VEHICLE_TRACK_IOU — If the IOU value between the detected person bbox and the vehicle bbox exceeds this threshold, the vehicle detection is considered false;
  • STREAM_FP_VEHICLE_TRACK_HUMAN_IMG_SIZE — inference size for the human detector.

CARS_Installer#

Changes:

  • Reduced the size of CARS_Installer Docker images: decreased the total image size and sped up the download process.
  • Updated default license plate recognition thresholds in .env-vanilla. Updated aggregation calculation policies and other parameters to improve license plate recognition.

General changes#

  • Fixed bugs and added improvements to enhance system stability.
