Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image acquisition devices have limited monitoring ranges, making it difficult for users to determine hot data in a global region effectively and intuitively due to overlapping monitoring regions with different hot data from adjacent devices.
Innovation Solution
Deploy multiple image acquisition devices for all-round monitoring, determine their overlapping monitoring regions, and use a computer device to process and combine hot data from these devices to create a unified heat map, ensuring accurate and intuitive identification of hot regions.

1Area of stationary object
If multiple image acquisition devices are deployed to monitor a global region, then the monitoring coverage is improved, but the overlapping monitoring regions cause conflicts in hot data from adjacent devices
Solution Approach 1:
The global region is segmented into multiple monitoring sub-regions, each assigned to a specific image acquisition device. Overlapping regions are further segmented and assigned to only one device based on proximity rules, eliminating data conflicts while maintaining comprehensive coverage.
Solution Approach 2:
Different regions are assigned different quality attributes based on their characteristics. Non-overlapping regions use normal hot data generation, while overlapping regions use proximity-based assignment rules to determine which device's hot data takes precedence, ensuring local data quality is optimized for each region type.
2Loss of information
If hot data from multiple adjacent image acquisition devices is directly superimposed for display, then the global region hot data is obtained, but overlapping color blocks appear in overlapping monitoring regions
Solution Approach 1:
The overlapping monitoring regions are extracted and identified separately from non-overlapping regions. By taking out the overlapping regions and applying specific assignment rules to them, the patent eliminates the overlapping color block problem while maintaining complete global hot data representation.
3Device complexity
If one single image acquisition device is used, then the device complexity is reduced, but the monitoring range is limited and global hot data cannot be determined
Solution Approach 1:
Multiple image acquisition devices are merged into a coordinated monitoring system with a central processing unit. The devices work together as a unified system, combining their individual monitoring ranges to achieve global region coverage while maintaining manageable complexity through standardized data processing protocols.

AI summary
Embodiments of the present application disclose a method, an apparatus and a storage medium for determining hot data in a global region, which belongs to the field of image processing. In the embodiment of the present application, the global region can be monitored by a plurality of image acquisition devices, and according to the hot data in the monitoring sub-region of each image acquisition device, the hot data in the global region can be determined. This solves the problem that the hot data in the global region cannot be obtained due to the limited monitoring range of one single image acquisition device. In addition, based on the monitoring sub-region of each image acquisition device, an overlapping monitoring region of the monitoring sub-regions of the image acquisition devices which are adjacent is determined. And then the hot data in the overlapping monitoring region is determined according to the hot data of the adjacent image acquisition devices. On this basis, the accuracy is high when determining hot data in a global region according to the hot data in the overlapping coverage region, which is conducive to the user's intuitive identification of hot regions based on the hot data in the global region.
