Embodiment
Below technical scheme of the present invention is described in further detail:
The invention discloses a kind of bridge tunnel 3D modeling data analytical approach, comprise following steps:
Step 1), arranging on tunnel bridge gathers fulcrum to gather the structured data at its place place;
Step 2), gather the data that each gathers fulcrum collection, after being packed, be sent to detection Forewarning Terminal;
Step 3), filters the data received and resolves computing;
Step 4), sets up with monitored bridge tunnel 3D model in proportion;
