Embodiment 1

[0020] This embodiment provides a method for processing traffic sign information. The method includes the following steps: acquiring traffic sign information, the traffic sign information including the reference direction of the traffic sign; and processing according to the acquired traffic sign information.

[0021] Traffic signs mainly include prohibition signs, instruction signs, warning signs, auxiliary signs, etc. The traffic signs involved in the present invention are prohibition signs and indication signs. Figure 1-Figure 5 Several kinds of traffic signs are shown respectively, among which, figure 1 A traffic sign that prohibits left turns. figure 2 A traffic sign that prohibits going straight. image 3 A traffic sign with a speed limit of 40 km / h. Figure 4 A traffic sign for going straight. Figure 5 Traffic sign for going straight or turning right.

[0022] Such as Figure 6 In the intersection model diagram shown, if field collectors advance along road a in...

Embodiment 2

[0039] Such as Figure 8 As shown, this embodiment provides a traffic sign information processing device, which includes: an acquisition unit for acquiring traffic sign information, the traffic sign information including the reference direction of the traffic sign; a processing unit for Flag information is processed. The processing unit is specifically: a conversion unit, which determines the road to which the traffic sign belongs according to the reference direction of the traffic sign, converts the content of the passage relationship between the road included in the traffic sign into the passage relationship between the road to which the traffic sign belongs and the connected road, and converts the content contained in the traffic sign into The instruction information is converted into road instruction information. The processing unit further includes: a navigation unit, configured to perform navigation according to traffic sign information. For the working principle of ea...

Abstract

The embodiment of the invention provides a traffic sign information processing method and device capable of solving the problem that a traffic sign reference direction determined though a track is false because a GPS (Global Position System) has positioning errors in the prior art. The traffic sign information processing method comprises the following steps of: acquiring traffic sign information, wherein the traffic sign information includes the traffic sign reference direction; and processing according to the acquired traffic sign information. The traffic sign reference direction is acquired on the spot in stead of acquiring traffic sign roads and the traffic sign reference direction by analyzing track data and images and recording data by a surveyor, thus the embodiment of the invention avoids misjudgment and enhances the operation efficiency; and in addition, the embodiment of the invention does not need to record the moving track of GPS equipment when acquiring traffic signs during field operation, thereby saving the storage space.

Description

technical field [0001] The invention relates to an information processing technology, in particular to a traffic sign information processing method and device. Background technique [0002] In the road network data of the electronic map used for vehicle navigation, there is a certain traffic relationship between connected roads (such as prohibiting left turns, etc.), and this traffic relationship between roads must be considered when planning the path; In addition, the road also contains traffic warning information (such as road speed limit 40km, etc.) to instruct navigation users to follow traffic rules and drive correctly. The passage relationship between roads and traffic warning information usually come from the field collection personnel's on-the-spot collection and subsequent processing of traffic sign information. The complete traffic sign information includes: the geographical position of the traffic sign, the type of the traffic sign, the content of the traffic sig...
