Traffic Panoramic Video System Solution
Video Stitching + 3D Real-Scene Fusion · Cross-Camera Continuous Target Tracking
Designed for intersections, road segments, and traffic hubs. The system stitches multiple surveillance feeds into a continuous panoramic video and overlays real video textures on 3D intersection models for three-dimensional traffic situational awareness. Vehicles, pedestrians, and other targets maintain trajectory continuity when switching between cameras, thoroughly solving cross-camera tracking disconnection.

Industry Pain Points
01
Fragmented Views
Intersection and road segment monitoring is scattered across multiple windows, making it impossible for operators to grasp the overall traffic situation of continuous road sections in a single view.
02
Difficult Cross-Camera Tracking
When vehicles and pedestrians switch between different cameras, target trajectories break, preventing continuous tracking of the same target across multiple feeds.
03
Lack of Spatial Awareness
Flat video cannot reflect the three-dimensional structure of intersections, lane hierarchies, or spatial relationships; incident positioning relies on manual experience.
04
Delayed Incident Response
Anomalies such as congestion, wrong-way driving, and accidents require manual screen-by-screen inspection, resulting in long detection and response times with complex response chains.
Solution Overview
Video Stitching + 3D Fusion
Video stitching + 3D fusion, building three-dimensional traffic panoramas
The solution builds traffic panoramic video capabilities in two steps: First, stitch multiple intersection cameras into a continuous panoramic video, eliminating fragmented views. Second, overlay the stitched video texture on 3D intersection models, creating an interactive real-scene 3D traffic environment. After both steps, cross-camera target tracking operates in continuous 3D space, and vehicle trajectories no longer break at camera boundaries.

Multi-Camera Real-Time Stitching
Stitch multiple intersection and road segment cameras into a continuous panoramic video, eliminating fragmented views for a single-screen grasp of overall traffic conditions.
✓
3D Real-Scene Fusion
Overlay intersection 3D models on the stitched video, mapping real video textures into 3D space for three-dimensional traffic situational awareness.
✓
Cross-Camera Continuous Tracking
Maintain trajectory continuity when targets switch between cameras, enabling continuous tracking of vehicles and pedestrians across the panoramic view without disconnection.
✓
AR Event Annotation
Overlay lane, intersection, event alert, and target trajectory tags on the panoramic or 3D view, making anomaly locations immediately apparent.
Technical Path
Two-step technical approach to upgrade from multi-channel independent monitoring to a 3D real-scene panoramic video system.

Fusion Result: 3D Real-Scene Traffic Panorama
Real video textures mapped onto 3D models, cross-camera target tracking continuously presented in three-dimensional space
Cross-Camera Continuous Tracking
Cross-Camera Continuous Tracking
Targets cross cameras, trajectories stay connected
In traditional multi-camera monitoring, when a vehicle moves from one camera's field of view to another, the target ID is lost and the trajectory breaks, requiring operators to manually re-locate the same vehicle across multiple windows. In the 3D real-scene fusion panorama, all camera views are unified into the same 3D spatial coordinate system, making target positions spatially continuous. Even across multiple camera boundaries, the system maintains target ID and trajectory continuity.
Vehicle Cross-Intersection Tracking
A vehicle enters from one side of the intersection, crosses through, and exits from the other side — the full trajectory is continuously displayed in the 3D scene without disconnection due to camera switching.
Pedestrian Cross-Zone Tracking
When pedestrians move between intersections, sidewalks, and green belts, the system continuously maintains target tracking, supporting trajectory review and behavior analysis.
Multi-Target Simultaneous Tracking
When multiple vehicles travel through an intersection simultaneously, the system assigns each target a unique ID and tracks them all concurrently in the panoramic 3D scene without interference.
Technical Architecture
01
Video Capture & Stitching
Integrate multiple rifle, dome, or panoramic cameras at intersections and road segments, completing calibration, distortion correction, and real-time stitching output.
02
3D Scene Modeling
Create 3D models of intersections and road segments, building detailed 3D scenes including lanes, road surfaces, buildings, and facilities.
03
Video & 3D Fusion
Map the stitched panoramic video textures onto 3D models in real time, forming an interactive real-scene 3D traffic environment.
04
Cross-Camera Tracking & Applications
Achieve continuous cross-camera target tracking within the fused scene, outputting trajectories, alerts, event playback, and situational displays.
Core Features
Function 01
Cross-Camera Continuous Tracking
When vehicles, pedestrians, and other targets switch between multiple cameras, the system maintains continuous target IDs and trajectories without breaking at camera boundaries. In panoramic or 3D views, a single vehicle traveling from one end of a road segment to the other always maintains a complete trajectory.
Function 02
Panoramic Main View
Multiple intersection and road segment cameras stitched into one continuous panoramic video, allowing operators to grasp overall traffic flow, congestion distribution, and anomaly locations without switching windows.
Function 03
3D Real-Scene Traffic Situational Display
Real video textures overlaid on 3D intersection models create a 3D traffic scene. Lane occupancy, queue lengths, and incident positions are intuitively presented in 3D space with multi-angle viewing support.
Function 04
Event Alerts & Playback
Anomalies such as congestion, wrong-way driving, illegal parking, and accidents are highlighted on panoramic or 3D views. Supports panoramic historical review by time, location, and event type to reconstruct incident processes.
