Object Tracking ROI Control for High-Resolution Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution images require significant computational resources for processing, limiting the efficiency of object tracking systems.
Innovation Solution
An object tracking apparatus that processes only a partial region of the image and controls the imaging apparatus to ensure the object of interest remains within this region, reducing computational demands while maintaining trackability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed on the entire high-resolution image, then object detection accuracy is improved, but computational resource consumption increases
Solution Approach 1:
The patent divides the high-resolution image into multiple regions of interest (ROIs) based on preliminary analysis or metadata. Only these specific regions are processed in detail for object detection and tracking, while other regions are processed at lower resolution or skipped entirely. This segmentation approach maintains detection accuracy for target objects while significantly reducing the total computational load by processing only relevant portions of the image.
2Reliability
If the imaging range is adjusted to keep the object within the processed region, then tracking reliability is improved, but system complexity increases
Solution Approach 1:
The system continuously monitors the position of tracked objects within the processed region and provides feedback to the imaging apparatus control. When an object approaches the boundary of the processed region, the system adjusts the imaging range (through panning, tilting, or zooming) to keep the object within the region of interest. This closed-loop feedback mechanism ensures reliable tracking while managing system complexity through coordinated control between the image processor and imaging apparatus.

AI summary
An object tracking apparatus (10) includes a target determination information acquisition unit (110), an image processing unit (120), and a control unit (130). The target determination information acquisition unit (110) acquires target determination information determining an object to be tracked. The image processing unit (120) detects the object to be tracked and tracks the detected object by performing image processing on a to-be-processed region being a partial region of an image acquired from an imaging apparatus (20). The control unit (130) controls an imaging range of the imaging apparatus (20) in such a way that the object to be tracked is included in the to-be-processed region.
