Multi-source information integrated underground water supply network mixed reality inspection method

The invention discloses a multi-source information integrated underground water supply network mixed reality inspection method, which specifically comprises the following five steps of: analyzing and classifying underground water supply network inspection object elements, and determining an information integration type; constructing an inspection information bearing base as a basis of multi-source information integration; routing inspection element multi-source information integration based on Unity and Visual Studio is carried out on the routing inspection information bearing base; based on Unity and Visual Studio, function development of the mixed reality inspection system of the water supply network is carried out; and the mixed reality system issues and polls the underground water supply pipe network by wearing the Hololens2 on the polling site. By combining multiple technologies such as MR, BIM, IoT and numerical simulation, multi-source heterogeneous information of the underground water supply pipe netw
