Method and device for sensing vulnerable traffic participants based on cloud

The invention discloses a method and device for sensing vulnerable traffic participants based on a cloud, and relates to the technical field of intelligent network connection automobile safety, and the method comprises the steps: integrating an AI model of the vulnerable traffic participants in the cloud; uploading the basic safety message and the traffic participant message, and performing data extraction and fusion to obtain a first roadside safety message and a second roadside safety message; if no roadside unit exists, the roadside unit with high credibility in the roadside safety messages is sent to the intelligent network connection vehicle; the road side unit sends the road side safety message with high credibility to the road side unit, and the road side unit sends the road side safety message with high credibility to the intelligent network connection vehicle; and the intelligent network connection vehicle judges whether the risk of collision with the vulnerable traffic participant exists or not, and
