The invention discloses a mobile acquisition method of a transportation facility. An acquisition vehicle is provided with an acquisition controller and a GPS (Global Position System) position indicator, wherein the roof of the acquisition vehicle is fixed with a vehicle-mounted fixing frame on which a plurality of cameras are fixed, each camera and the GPS position indicator are electrically connected with the controller respectively, the acquisition vehicle travels according to an appointed road section, encountered traffic signs are collected, collection videos, collection time and GPS information and other traffic facility metadata are stored and identified, information acquisition and statistics of all traffic facilities of the road section R are completed and synchronized with data in the traffic sign database. The mobile acquisition method is characterized in that the traffic sign data in the traffic facility metadata is automatically extracted by a traffic sign detecting and indentifying technology, through a straight line detection and character recognition technology, the traffic sign attribution is automatically input and identified and an attribute information table is fabricated, and the error caused by manually marking is greatly avoided when the manpower demand is greatly reduced.
