TWO-STAGE INTELLIGENT FAULT DIAGNOSIS OF MOTORS BASED ON VISUAL IMAGE FEATURES
Published 2024-01-01“…Aiming at the new challenges in efficiency and reliability in the field of fault diagnosis in recent years,a coarsefine fault diagnosis method for induction motors based on the symmetrized dot pattern(SDP)was proposed.In this method,firstly,the vibration signals of each faulty motor were converted into snowflake images by SDP method,and then a two-stage fault diagnosis framework of coarse-fine classification was designed for image feature extraction and classification.In the coarse classification stage,the color histogram features and the support vector machine(SVM)were used to diagnose the samples,and a threshold was selected to determine the samples for the coarse classification.In the fine classification stage,Gist features that can extract image details and SVM were used to diagnose the remaining samples.Experimental results show that the proposed method combines the advantages of color histogram features and Gist features,can achieve the most reliable diagnosis with relatively high efficiency,and has certain anti-noise ability.…”

Research on voxel-based land complex modelling and adaptive resolution expression methodology
Published 2025-08-01“…In order to improve the efficient use of land complex resources, explore the application of voxel model in land complex change monitoring, and propose a voxel-based land complex modelling and adaptive resolution expression method for the problem of large data redundancy and poor expression effect in the dynamic expression of land complex voxel model.Firstly, voxel classification and stratification are carried out through element characteristics to determine the elements suitable for voxel modelling; then, based on the analysis of terrain factors, the adaptive resolution expression method is constructed by optimizing the node evaluation criterion through the comprehensive consideration of sight distance and comprehensive terrain complexity.The results show that the method in this paper can achieve efficient expression and smooth scheduling of land complex voxel models at different resolutions, thus significantly reducing the computational complexity while maintaining the expression accuracy of important features.…”
