embodiment one
Fig. 1 shows the first realization flow of the website acquisition method that the embodiment of the present invention one provides, and for convenience of explanation, illustrate only part related to the present invention.
As shown in Figure 1, described website acquisition method comprises:
In step S101, automatically gather the video information of GPS (Global Position System) GNSS data and vehicle-mounted digital video recorder.
In the present embodiment, by supporting in the process that vehicle-mounted DVR (digital VTR) equipment of GNSS function travels at vehicle, the GPS (Global Position System) GNSS data current according to certain time interval collection vehicle and video information, and described GNSS data and video information are stored to the memory device of specifying.Preferably, described certain time interval can be the time interval of one second.Support in the process that vehicle-mounted DVR (digital VTR) equipment of GNSS function travels at vehicle, the GNSS data that collection vehicle per second is current and video information.Described GPS (Global Position System) GNSS includes but not limited to GPS navigation system, also comprises other global position systems.
In step s 102, analyze described GNSS data, obtain the GNSS positional information of website.
In the present embodiment, from memory device, derive the GNSS data collected, it is analyzed, obtain the GNSS positional information of website.Described website can be bus station, subway station etc., is preferably bus station.Preferably, the step that GNSS data is analyzed is comprised:
1. filter out from the GNSS data collected and meet pre-conditioned GNSS positional information.
2. filtered out GNSS positional information is divided in the upstream or downstream direction of vehicle operating according to deflection.
3. the GNSS positional information in pair upstream or downstream direction is analyzed, and obtains the GNSS positional information of all websites on this traffic direction.
Because bus is when pulling in parking, its travel speed is generally zero, and therefore, the speed that the described pre-conditioned GNSS of being preferably gathers is zero.
Subsequent embodiment will carry out detailed describing to step S102, does not repeat them here.
In step s 103, in conjunction with video information, the website GNSS positional information got is verified, obtain the website GNSS positional information corresponding with real site.
In the present embodiment, after getting the GNSS positional information of website, from memory device, transfer video information, according to described video information, the website GNSS positional information got is confirmed, and revise, to obtain the website GNSS positional information corresponding with real site.Due to bus run into red light, block up and dodge pedestrian time, vehicle can slow down, GNSS gather speed also may be zero.Therefore, need to confirm the website GNSS positional information got according to video information, judge that whether position corresponding to this website GNSS positional information be whether position corresponding to bus station and this website GNSS positional information be accurate.When the Bu Shi bus station, position that described website GNSS positional information is corresponding, delete this website GNSS positional information; When deviation appears in position corresponding to this website GNSS positional information and actual bus station, according to described deviation, website GNSS positional information is revised, thus obtain the website GNSS positional information corresponding with position, actual bus station.
In the present embodiment, the GNSS data in the vehicle-mounted digital video recorder collection vehicle operational process of GNSS and video information is supported by employing; Analyze described GNSS data, obtain the GNSS positional information of website; In conjunction with video information, the website GNSS positional information got is verified, obtain the website GNSS positional information corresponding with real site.Thus achieve the automatic collection of bus station positional information, improve the efficiency that bus station gathers, save human cost and time cost; Further, because this website automatic acquiring method does not need the cooperation of driver automatically to complete, the potential safety hazard that acquisition mode in the past exists can be eliminated, and the interim adjustment of bus station can be responded fast.
