A method, system, device, and medium for assessing the perceived consistency of tourist destinations based on social media images.

Abstract

This invention relates to a method, system, device, and medium for assessing the perceptual consistency of tourist destinations based on social media images. The method includes: extracting landscape spatial visual representation parameters from social media images; calculating a media perception score by combining a constructed image authenticity correction operator and a media perception evaluation index; acquiring the subject's physiological electrical signals and environmental disturbance parameters; performing environmental response decoupling and bias compensation on the physiological electrical signals using the environmental disturbance parameters; obtaining a site perception score by combining the physiological perception evaluation index; constructing a perceptual feature vector pair from the two scores; calculating the coupling deviation between the vector magnitude and spatial orientation as a perceptual consistency coefficient and determining the level; if the level is below a threshold, performing deviation tracing based on visual representation and environmental disturbance parameters, extracting spatial causes, and integrating and outputting the evaluation results. Therefore, this invention quantitatively assesses perceptual consistency and accurately traces spatial causes, providing reliable data support for tourism planning.
