Target Polygon Vertex Tracking for Video Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing target tracking methods in video processing require significant calculations to track entire objects, leading to reduced real-time performance and accuracy.
Innovation Solution
The method involves acquiring a target video, performing polygon detection on the first image frame to obtain vertices of a target polygon, and then tracking these vertices in subsequent frames, allowing for efficient tracking by focusing on the vertices rather than the entire polygon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire target object is tracked in each frame of the video, then the tracking accuracy is maintained, but the calculation amount increases significantly, reducing real-time performance
Solution Approach 1:
The patent segments the target object tracking into vertex tracking. Instead of tracking the entire target object, the method identifies and tracks only the vertices of the target polygon in each frame. This segmentation reduces the number of tracked elements from the entire object to just its corner points, significantly decreasing computational load while preserving tracking accuracy through geometric reconstruction of the target shape from vertex positions.
2Reliability
If the entire target object is tracked in each frame of the video, then the completeness of tracking information is ensured, but the calculation complexity increases, reducing processing speed
Solution Approach 1:
The patent extracts only the essential features (vertices) from the complete target object for tracking purposes. By taking out just the corner points that define the target polygon's geometry and tracking these extracted features instead of the entire object, the method reduces calculation complexity while maintaining tracking reliability through the geometric properties of polygons.
