Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] A method for mobile collection of traffic facilities, comprising the following steps:

[0033] (1) Collection preparation: Make a collection plan and collection route R, and prepare a collection vehicle.

[0034] collection car such as figure 1 As shown, the vehicle body 8 of the collection vehicle is provided with a collection controller 1, a switch 2, and an industrial-grade GPS locator 3, and a vehicle-mounted fixing frame 7 is fixed on the front side of the roof of the vehicle body 8, and three vehicle-mounted fixing frames are fixed on the vehicle-mounted fixing frame 7. The cameras are the first camera 4, the second camera 5, and the third camera 6, respectively. The first camera 4, the second camera 5, and the third camera 6 are respectively connected to the input end of the switch 2, the output end of the switch 2, and the GPS ...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of traffic information collection, in particular to a method for mobile collection of traffic facilities. Background technique [0002] Real-time and effective traffic facility data is a decisive factor for road operation managers to grasp the macro situation of the road, accurately grasp and form correct emergency decision-making. [0003] The traditional collection methods of transportation facilities are mainly manual collection and vehicle collection: the manual collection method is that the collection personnel go to the transportation facilities, and the combination of camera photography and manual input (paper report or handheld computer) is used to record, and the workload is large. It often relies on manual identification and query, which is prone to problems such as missed collection and repeated collection; vehicle collection is collected and delivered through on-board cameras, which is expensive,...
