Method for constructing panoramic three-dimensional map for driving test based on GNSS differential positioning

The invention belongs to the technical field of panoramic three-dimensional map construction, provides a method for constructing a panoramic three-dimensional map for a driving test based on GNSS differential positioning, and aims to achieve the technical purpose that improvement of the method for constructing the panoramic three-dimensional map for the driving test based on GNSS differential positioning is provided. To achieve the technical purpose, the method adopts the following technical scheme: a plurality of GNSS differential positioning base stations are erected and fixed within the range of a driving school site, the base stations actively send differential correction signals to a mobile station through radio or a wireless network, and the mobile station receives the differential signals in a real-time and dynamic manner as a car-mounted GNSS mobile receiver, carries out analysis processing on the received signals, and calculates coordinate values of points to be detected; modeling is carried out on a
