2results about How to "Increase data dimension" patented technology

This invention discloses an environmental health analysis method and system based on egg-laying hen farming, relating to the field of livestock environmental monitoring technology, including methods based on NH3 concentration and VOCs. S Concentration and NO X Two-dimensional empirical wavelet transform is performed on the concentration to calculate texture intensity, gradient direction, and local entropy. Spatial texture features are obtained by horizontal stacking based on NH3 concentration, HRV standard deviation, and VOC. S Concentration and NO X Concentration is calculated, time-domain features are calculated, and frequency-domain features are calculated based on heart rate and HRV standard deviation. Weighted summation yields the SPS joint features. This invention improves data dimensionality and monitoring comprehensiveness by collecting multimodal data and calculating spatial texture features, thereby enhancing the accuracy of environmental dynamic analysis. Through SPCA dimensionality reduction and weighted risk scoring models, it provides accurate quantitative evidence for the environmental health status of laying hens, improving the health management level and production efficiency of laying hen farming.
