MV3DT projects detections from multiple calibrated cameras into a shared 3D coordinate system, assigning globally consistent object IDs using MQTT-based tracklet sharing. AMC automates camera calibration by analyzing tracked object trajectories, eliminating the need for manual checkerboard patterns, and optionally uses the VGGT model for higher accuracy. DeepStream 9.1 also introduces 13 modular agentic skills compatible with coding agents like Claude Code and Codex, enabling natural-language-driven pipeline setup and deployment. The release supports NVIDIA JetPack 7.2 for Jetson edge platforms and is fully open-sourced on GitHub. ## Full article daily.dev links to this article rather than hosting it.
