Interactive Terrain Map Real-Time Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video surveillance systems lack a quick and accurate real-time display of all moving objects on a terrain map, making it difficult for operators to monitor and respond to potentially dangerous situations effectively, especially in large areas with multiple cameras.
Innovation Solution
A system that links multiple video cameras to an interactive terrain map, using an object tracker to analyze video data and generate metadata, allowing for real-time display of moving objects in 2D or 3D, with features like adjustable camera angles, trajectory display, and alert rules for suspicious activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operators switch between different cameras to monitor moving objects, then they can see detailed views from each camera, but they cannot quickly grasp the overall situation and may miss details due to the time required to switch cameras
Solution Approach 1:
The patent merges multiple camera views onto a single terrain map display, combining the strengths of both individual camera monitoring and overall situation awareness. Moving objects detected by any camera are plotted on the terrain map with their current positions, allowing operators to see the complete picture across all monitored areas simultaneously without needing to switch between camera feeds.
Solution Approach 2:
The patent transitions from a two-dimensional camera view switching paradigm to a spatial dimension approach by projecting moving object positions onto a terrain map. This adds a geographical spatial dimension to the monitoring system, where objects are displayed according to their actual locations on the terrain rather than being confined to individual camera frames, enabling comprehensive oversight in a single view.
2Ease of manufacture
If the system displays only marks on the terrain map to indicate object locations, then the system is simple to implement, but it is difficult to recognize the full picture of what is happening
Solution Approach 1:
The patent applies local quality by enhancing specific elements on the terrain map with detailed visual information. Instead of uniform marks, the system displays actual video frames or images of moving objects at their detected locations on the terrain map. This allows operators to see both the geographical position (from the terrain map) and the detailed visual context (from the camera images) simultaneously, providing comprehensive situational understanding while maintaining the simplicity of the terrain map interface.
3Measurement precision
If the system uses complex algorithms to track objects across multiple cameras, then tracking accuracy improves, but the system becomes more complicated and harder to implement
Solution Approach 1:
The patent introduces the terrain map as an intermediary layer between multiple camera systems. Rather than implementing complex cross-camera object tracking algorithms, the system uses the terrain map as a common reference frame where objects detected by any camera are plotted based on their geographical positions. This intermediary approach simplifies the system architecture by avoiding the need for sophisticated inter-camera coordinate transformation and object identification algorithms, while still achieving accurate tracking through the spatial reference provided by the terrain map.
Data Source
AI summary
The invention refers to the area of data visualization on the terrain map, and more specifically to the analysis of video data received from cameras linked to an interactive terrain map for subsequent display in real time of all objects moving in the frame on the mentioned terrain map. A system for displaying the moving objects on the interactive terrain map comprising multiple video cameras, an object tracker, data processing and storage device that has a graphical user interface (GUI). GUI comprising a display unit, a unit for setting the interactive map, a unit for setting the video camera viewing angle. The data processing and storage device is configured to receive the video data from the video cameras, as well as metadata of all moving objects from the object tracker, analyze the received video data and object metadata, display the real image moving object in real time on an interactive map at location on the map where this object is currently moving. The image location on the map and the image of the moving object itself change in real time based on the video data and metadata of the moving object. The interactive map displays all moving objects that fall within the field of vision of any of the video cameras linked to the map, for which the user has preset the viewing angle.
