s2, setting teaching, namely firstly, according to teaching contents related to teaching activities, inputting corresponding teaching contents into a data processing server for storage, simultaneously, carrying and positioning teaching aid models for teaching through a tray, embedding the tray and the teaching aid models carried by the tray into a display cavity for storage when the teaching aids do not participate in the teaching activities, then, selecting a corresponding number of the teaching aid models to participate in the teaching activities according to the number of students in teaching interaction, then, each control terminal in the teaching aid corresponds to one student, and the students adjust the working positions of all operation platforms according to learning needs, so that the setting of the teaching aid is completed;
s3, learning operation, wherein after the step S2 is completed, the student can obtain corresponding teaching and learning materials from the data processing server to learn by controlling the control terminal; the operating position of another party through drive guide rail adjustment locating plate, and the contained angle of the surveillance camera head group optical axis that the locating plate is connected and the tray axis and the light collection degree of teaching aid model on the tray, carry out video information collection and three-dimensional information scanning to the teaching aid model through the surveillance camera head, then say plane and the three-dimensional data book transmission of scan to data processing server, utilize the three-dimensional information show subsystem based on BIM and GIS in the data processing server to operate the operation to the data of gathering through controlling the terminal by the student, thereby realize the needs of three-dimensional modeling teaching operation.
10. The use method of the BIM/GIS fusion-based comprehensive teaching platform according to claim 1, characterized in that: in the S2 step, when carrying out information acquisition to the teaching aid model through the locating plate, the student acquires the data acquisition with the help of controlling terminal when gathering data, and the display of accessible top rear end face acquires data acquisition information in addition to the operating position of the control locating plate and the monitoring camera group that the locating plate is connected is controlled in the suggestion of display information and the operation is adjusted.
