Crowd Annotation Services for Public Safety, Density Mapping, and Behavioral Analytics

Crowd Annotation Services
Understanding crowd behavior is essential for public safety, event management, transportation planning, and smart city operations. AI models trained on annotated crowd data can estimate density, identify movement patterns, detect congestion, and support early warning systems during high traffic events.DataVLab provides crowd annotation services for smart city platforms, public safety agencies, stadium and event operators, transportation hubs, retail analytics companies, and AI startups. We annotate CCTV feeds, drone footage, overhead views, entrances, platforms, and large gatherings.We support person detection, head counting, density estimation, region based counting, flow direction annotation, trajectory labeling, and crowd event tagging. Depending on the dataset, we annotate bounding boxes, keypoints, head points, segmentation masks, or region level density maps.Quality control includes multi step review, occlusion handling validation, consistency checks across scenes, and accuracy scoring on high density footage.
Accurate crowd labeling for density estimation, people counting, and movement analysis.
Support for overhead views, CCTV, drone footage, and high density scenes.
Consistent workflows adapted to occlusions, perspective variation, and large gatherings.
How DataVLab Supports Crowd Analytics and Public Safety AI
We annotate crowded environments using structured guidelines designed for safety monitoring and density modeling.

People and Head Detection
Bounding boxes, head points, or segmentation masks
We label individuals or head points in high density environments.

Crowd Density Mapping
Region level density annotations for analytics
We annotate density zones and crowd concentration levels.

Flow Direction and Trajectory Annotation
Movement understanding for public safety and facility planning
We track pedestrian direction, movement paths, and flow transitions.

Event and Incident Tagging
Labels for unusual or safety relevant behaviors
We annotate buildup, irregular flow, sudden stops, and pushing movements.

Drone Based Crowd Annotation
Top down large area labeling
We label crowd spread and density zones from aerial footage.

Entrance and Queue Monitoring
Annotation for bottleneck and capacity management
We annotate queue length, occupancy, and waiting line behavior.
