1Measurement precision

If the input resolution is expanded to improve detection accuracy, then the detection precision is improved, but the model training speed decreases and power consumption increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidmodel training speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The high-resolution remote sensing image is divided into multiple sub-images, which are then processed in parallel by multiple detection models. This segmentation approach maintains high detection accuracy while reducing the computational burden on each individual model, thereby improving overall processing speed and reducing power consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple detection models with different input resolution requirements are deployed to handle different sub-images. Some models process full-resolution sub-images for high-precision detection, while others process down-sampled sub-images for faster processing. This multi-functional approach allows the system to achieve both high detection accuracy and efficient processing speed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If the input resolution is expanded to improve detection accuracy, then the detection precision is improved, but the power consumption increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidpower consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The image is segmented into multiple sub-images that are processed in parallel. This distribution of computational workload across multiple smaller tasks reduces the peak power consumption compared to processing one large high-resolution image at a time, while maintaining overall detection accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sub-images are processed with different model resolutions based on their specific characteristics. Sub-images containing important targets are processed with higher resolution models, while other areas use lower resolution models. This localized quality adjustment optimizes power consumption by applying high computational resources only where necessary.

Inventive Principle:
Principle #3Local quality

If image segmentation is used to process high-resolution images, then the processing efficiency is improved, but the detection accuracy is affected

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The image is divided into overlapping sub-images with appropriate overlap regions. This segmentation enables parallel processing efficiency while the overlap ensures that targets spanning multiple sub-images are not missed, thereby maintaining detection accuracy despite the division of the image.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detection results from multiple sub-images are merged and integrated to form the final detection result. This merging process combines the advantages of parallel processing efficiency with comprehensive target detection, ensuring that no targets are lost during the segmentation process.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present application discloses a target detection method and device for a high-resolution remote sensing image, which comprises: acquiring an original high-resolution remote sensing image from a sensor; acquiring target information of an area and an expanded area of the area expanding around by a predetermined distance; adaptively partitioning the original high-resolution remote sensing image to obtain different cluster areas to be detected, and obtaining an area required to be detected and an area not required to be detected; selecting a model of the area required to be detected and generating a target detection scheme; executing the target detection scheme to obtain a detection result; determining whether a computing platform has extra computing resources to detect the area not required to be detected, if so, performing dynamic partition detection for the area to obtain a detection result, and merging the detection results into a target detection result.
