O que é CVAT?
CVAT is a complete data labeling suite for teams building real-world AI. It turns raw images, videos, and 3D data into model-ready datasets through AI-assisted labeling, quality control, team collaboration, progress monitoring, and flexible deployment via cloud, self-hosted, or managed services.
Recursos principais
Data import from local and cloud storage
Upload local datasets and existing annotations; connect Amazon S3, Azure Blob Storage, Google Cloud Storage, S3-compatible buckets, or self-hosted storage.
Project, task, job, and team management
Organize annotation work into projects, tasks, and jobs; assign annotators, reviewers, and contributors; manage roles, permissions, stages, statuses, and ownership.
Manual and AI-assisted labeling tools
Create boxes, polygons, masks, skeletons, tags, and tracks; accelerate with SAM 2, SAM 3, Ultralytics, Hugging Face models, or custom models for detection, segmentation, tracking, and pose estimation.
Annotation validation and quality control
Review jobs via validation and acceptance stages; measure quality with ground truth, honeypots, and consensus workflows; resolve issues with traceable quality decisions.
Progress and workload monitoring
Track progress across projects, tasks, and jobs; monitor team workload and completion status; identify bottlenecks and measure annotation and validation throughput.
Dataset export and workflow integration
Export in 20+ formats including COCO, YOLO, KITTI, Cityscapes, and Pascal VOC; automate via API, SDK, and CLI; build custom integrations for ML workflows.
Multi-modality support
Annotate images (bounding boxes, masks, polygons, keypoints), videos (object and skeleton tracking), and 3D point clouds (detection, classification, sequence tracking); audio coming soon.
Managed annotation services
Outsource labeling to 300+ dedicated annotators across 12 time zones with real-time dashboards, multi-stage QA, rework guarantees, and scale from 1,000 to 100M+ labels.
Enterprise security and compliance
GDPR, CCPA, and EU AI Act compliant; encryption in transit and at rest; RBAC and SSO; access logging and audit trails; on-premises and air-gapped deployment options.
