The application discloses an image semantic segmentation model which is composed of a designed mixed attention focusing method, an attention rectification residual module (ARRM) and a mixed feature integration module (MFFM), is trained in a deep supervision mode as a whole, is reasonably provided with deformable convolution, is combined with a constructed multi-scale spatial attention module (MSP) and a double-pooling attention module (DPA) to be jointly optimized, and the problem of small target feature segmentation difficulty is solved. In order to reflect the excellent performance of the model on a downstream task, the training between different data sets is completed in a transfer learning mode, and the application range of the model is expanded. Finally, grouping convolution is added in the backbone network, the calculation cost is greatly reduced, and the problem of high training cost of the segmentation model is solved under the premise of guaranteeing the segmentation effect.

This invention provides a method, apparatus, and device for detecting the physicochemical parameters of oil, relating to the fields of spectral analysis and industrial equipment condition monitoring. The method includes: acquiring hyperspectral data of the oil to be tested; inputting the hyperspectral data into a pre-trained spectral decoupling network to output a base spectral component related to the oil brand, and a common component feature vector unrelated to the oil brand but related to the oil's health status; matching the common component feature vector with a pre-built general reference library to determine the physicochemical parameter values ​​of the oil to be tested. The method of this application achieves efficient and accurate detection of physicochemical parameters of oils from multiple brands, breaking the limitation of "one model per brand," effectively improving the accuracy of the detection results and the generalization ability across brands, significantly reducing the deployment and maintenance costs of the detection system, and significantly improving the practicality of multi-brand oil condition monitoring.

This invention relates to the field of machine vision and industrial defect detection, specifically a metal sign surface inspection system based on machine vision. It includes modules for image acquisition, feature analysis, strategy decision-making, dual detection, and result output. The system extracts surface image features to construct a visual feature space and calculates semantic drift entropy. Its core is to dynamically switch based on the comparison between the entropy value and a preset danger threshold: at low entropy values, a generative vision model is called to extract depth features; at high entropy values, a physical optical morphological filtering algorithm is called to extract basic morphological features. This invention breaks the limitations of a single detection architecture, utilizes adaptive scheduling to solve the problem of environmental light spot noise interference, and balances the ability to identify subtle surface defects under stable lighting with the robustness of structural detection under complex optical interference.
