Three-dimensional visual risk early warning method based on shield real-time monitoring system

The invention discloses a three-dimensional visual risk early warning method based on a shield real-time monitoring system. The method comprises the following steps of S1, building a three-dimensional visual scene; S2, inputting risk source information; S3, inputting and managing monitoring points and monitoring data; and S4, performing risk early warning and information display. According to the method, shield tunneling machine tunneling data of the shield real-time monitoring system is integrated, and the three-dimensional visual scene along a tunnel is established; when a shield tunneling machine tunnels to a risk source influence range, the shield real-time monitoring system automatically performs early warning on a corresponding area and displays the early warning in the three-dimensional visual scene; a manager is assisted to master the spatial position relation between the shield tunneling machine and a risk source; and meanwhile, construction alarm information of the shield monitoring system and contr
