Data comparison collision method and device

The invention discloses a data comparison collision method and device. The method comprises the steps of obtaining a specified space-time range; performing data processing on the trajectory data in the space-time range, wherein the data processing comprises the steps of standardizing the track data into spatio-temporal data and performing spatio-temporal index processing on the spatio-temporal data to obtain spatio-temporal feature index data; performing spatio-temporal feature denoising processing on the spatio-temporal feature index data to obtain denoised spatio-temporal feature index data,wherein the spatio-temporal feature denoising processing comprises the steps of marking whether corresponding data in one or more spatio-temporal parameter items exists or not from spatio-temporal feature index data; extracting collision data to be compared from a preset spatial-temporal feature library according to spatial-temporal index dimensions in the denoised spatial-temporal feature indexdata; and performing traje
