The invention relates to an urban parking global credible sensing method based on crowdsourcing data. The method comprises the following steps: S1, constructing a parking space detection model based on deep learning; s2, defining four influence factors, combining the four influence factors with a simulation scene, and researching and analyzing the correlation between the influence rule of different influence factor combinations on the parking space detection model and the perception success rate; s3, evaluating the four defined influence factors, establishing a parking space state perception failure probability prediction model under the interference of different external factors, and predicting the reliability of the identification of the parking space detection model; and S4, establishing a multi-vehicle sensing simulation scene, analyzing an influence rule of a motorcade scale on the parking space detection model, constructing a data freshness model, defining a credible fusion method of crowdsourcing data, and completing credible sensing of the urban roadside parking space state. Compared with the prior art, the method has the advantages that the credible sensing accuracy of the roadside parking space state is improved, the credibility is improved, and the real-time performance is high.
