The invention provides a lighting scene generation method based on acousto-optic interaction and an intelligent control system for realizing acousto-optic interaction. The lighting scene generation method based on acousto-optic interaction comprises the following steps: acquiring audio track information of target music; processing the audio track information to obtain audio data; identifying the audio data to determine features of the target music; and controlling the lamp to generate an illumination scene matched with the target music according to the characteristics. Compared with the prior art, perfect fusion of music and light can be realized, and the immersion of audiences is enhanced.

The application discloses a cognitive disorder screening method and device based on an XR eye tracker and near-infrared brain imaging, and the device comprises an extended reality scene generation module, an eye tracker data acquisition module, a near-infrared brain imaging module, a data analysis processing module and a cognitive disorder screening module. The extended reality scene generation module is used for generating and displaying a virtual reality scene and an augmented reality scene containing a cognitive task. The eye tracker data acquisition module is used for collecting eye movement data information sets of a user in real time when the user completes the cognitive task in the virtual reality scene and the augmented reality scene. The near-infrared brain imaging module is used for collecting blood oxygen information sets of the cerebral cortex of the user in real time when the user completes the cognitive task in the virtual reality scene and the augmented reality scene. The cognitive disorder screening module is used for performing cognitive disorder screening processing on evaluation process information, the eye movement data information sets and the blood oxygen information sets of the cerebral cortex, and obtaining cognitive disorder information of the user.

This invention relates to the field of population spatiotemporal distribution modeling technology, and proposes a population model generation method based on crowdsourced data, comprising the following steps: Step 1, collecting socioeconomic and natural environment data to obtain standardized multi-source raster data; Step 2, based on the standardized data, constructing a daytime population weight layer by training a heterogeneous basic regression model with five-fold cross-validation and building an adaptive spatial weighted support vector regression meta-learner; Step 3, extracting building volume and nighttime light intensity raster layers from the standardized data to construct a nighttime population weight layer; Step 4, constructing a non-working day population weight layer by weighted fusion based on the day and night weight layers; Step 5, constructing basic spatial mapping units to complete high-scale downscaling reconstruction of population space, obtaining initial high-resolution population distribution results; Step 6, introducing a time smoothing model to correct the temporal inconsistency problem of the initial results, generating the final population distribution model. This invention effectively solves the problems of insufficient spatiotemporal resolution, poor time-segment adaptability, and unreasonable assignment of missing data areas in traditional population distribution models, providing accurate, comprehensive, and highly usable population distribution data support for scenarios such as urban planning, resource allocation, and emergency management.
