- the present invention proposes a method and system for post-processing analysis and mining of economic geographic elements.
- a post-processing analysis and mining method for economic geography elements including the following steps:
- the vehicle passing time in different collection time periods is obtained, and the vehicle passing time is the observable duration of the roadside billboard on the road t obv Estimate.
- the step S2 includes: dividing the road into different lanes; and obtaining all road vehicles on each lane of the current road through the estimation of the vehicle passing time as the observable duration t obv of the roadside billboard of the road, thereby obtaining the road score.
- the total observable duration of the billboard established by the segment ⁇ t obv .
- the salient elements of the image are mined to obtain the best outdoor advertising area from the list of potential candidate locations for outdoor advertising.
- the types of print advertisements and video advertisements are determined.
- the overall maximum duration of the video advertisement is set to obv / 2. In order to ensure that when the vehicle passes, the occupants of the vehicle can completely watch at least one video advertisement.
- the invention also provides a post-processing analysis and mining system for economic geography elements, which includes the following units:
- a data acquisition unit which is used to collect the judgment of the observable section of the roadside billboard at any point on the current driving road by the environment sensing sensor, including the observable closest point p 1 that does not affect the driving safety of the driver, and the content of the billboard The most visible observable point p 2 ;
- a duration estimation unit is configured to obtain vehicle transit times in different collection periods based on the distance dist between p 1 and p 2 and vehicle speed information measured by an on-board sensor, and the vehicle transit times are available for the roadside billboard on the road. Estimate of observation duration tobv .
- the duration estimation unit includes: dividing a road into different lanes; obtaining an observable duration t obv of a billboard on the road side of the road through the passing time of the vehicle to obtain all the vehicles on each lane of the current road, thereby obtaining the road
- the total observable duration of the billboard established in sections is ⁇ t obv .
- the salient elements of the image are mined to obtain the best outdoor advertising area from the list of potential candidate locations for outdoor advertising;
- the overall maximum duration of the video advertisement is set to obv / 2.
- Implementing the method and system for post-processing analysis and mining of economic and geographic elements has the following beneficial effects compared with the prior art: it can effectively use unused sensor raw data in the process of map production and mine its derived information, The process does not affect the traditional map production and production process, and overall enhances the added economic value of the collection business. Compared with the traditional economic geography survey form, it can reduce the time cost, labor and material costs of collecting the original survey data; use crowdsourcing to complete In this task, the data information finally obtained can be verified and iteratively updated again through various types of information collected by the sensor, without the need for large-scale secondary visits to ensure the timeliness of the economic and geographic information collected.
- Figure 1 is a flowchart of post-processing analysis and mining methods of economic geography elements
- Figure 2 is a schematic diagram of the road and outdoor billboard scene.
- the sensor data is only used to generate road and road information, elevation sign information and other high-resolution map required elements, but in fact the original sensor data contains Point cloud or visual sensor information such as outdoor billboards, high-rise buildings, overpasses, pedestrian bridges, etc., generally do not participate in the construction, production and post-production of high-precision maps.
- the raw data that is not used later in this type of high-precision map collection will include optimization of potential determinants of advertising economic benefits such as the location of outdoor billboards, the contents of outdoor advertising panels, and the maximum length of dynamic advertising singles parameter.
- the length of time for the advertisement to be selected, and the prediction is completed according to the traffic volume at different times.
- the first is the analysis of the economic benefits of the existing billboards: as shown in Figures 1 and 2, a post-processing analysis and mining method of economic geographic elements, which includes the following steps:
- the environment-aware sensor such as a camera
- P 1 is the closest observable point that does not affect the driving safety of the driver
- P 2 is the farthest observable point where the billboard content is visible.
- the judgment of the observable closest point and the observable farthest point depends on the subjective judgment of the person, but in fact, the margin of the camera's limited field of view and the smallest resolvable billboard imaging pixel size can be used to quantify this.
- Technical indicators that can observe the nearest point and the farthest point.
- the vehicle passing time in different acquisition time periods is obtained, and the vehicle passing time is the observable duration of the roadside billboard on the road t obv Estimate.
- Outdoor billboards should be implemented so that the driver and occupant of the vehicle traveling along the road can pay more attention to the contents of the advertising display board without affecting the driving safety, which is directly related to the dynamic driving process of vehicles on the road You can directly observe the length of time of this exhibition board.
- the step S2 includes: dividing the road into different lanes; passing the vehicle through time to the road
- the observable duration t obv of the roadside billboard is estimated to obtain all the vehicles in each lane of the current road, so as to obtain the overall observable duration ⁇ t obv of the billboard established on this road segment.
- the second is a candidate location where outdoor advertisements can potentially be placed during the driving of the current regional road: in the method of post-processing analysis and mining of economic and geographic elements according to the present invention
- the candidate elevation space includes "the optimal area for setting advertisements”, “other sub-optimal areas”, and “poor advertising performance areas”.
- the order of the total observable duration needs to be used to determine the optimal region.
- the "candidate elevation space” represents all optional regions that have not undergone any screening. It is also necessary to combine different road segments to determine the observation duration of different candidate elevation spaces in order to evaluate the list of potential candidate locations.
- the salient elements of the image are mined to obtain the best outdoor advertising area from the list of potential candidate locations for outdoor advertising.
- the outdoor advertising area can obtain higher visual attention, saliency, and continuous attention time, which is a technical index to quantify the best subjective perception of humans.
- the types of print advertisements and video advertisements are determined.
- the third is to determine whether the type of advertisement used by the advertising board is flat or dynamic, and the optimal playing time of dynamic advertisements: In the method of post-processing analysis and mining of economic and geographic elements described in the present invention,
- the overall maximum duration of the video advertisement is set to obv / 2.
- statistical analysis can be performed based on the historical advertising data of advertising providers in order to confirm that it does not affect the upper threshold of road traffic safety, that is, the longest observation time.
- the advertisement duration should have an upper bound tobv and a lower bound tobv / 2, that is, the length of time during which a person in the vehicle can observe the complete dynamic video advertisement. Under the guidance of this length of time, it is possible to more reasonably arrange the form of advertising in different time periods in exchange for the greatest economic benefits.
- the invention also provides a post-processing analysis and mining system for economic geography elements, which includes the following units:
- a data acquisition unit which is used to collect the judgment of the observable section of the roadside billboard at any point on the current driving road by the environment sensing sensor, including the observable closest point p 1 that does not affect the driving safety of the driver, and the content of the billboard The most visible observable point p 2 ;
- a duration estimation unit is configured to obtain vehicle transit times in different collection periods based on the distance dist between p 1 and p 2 and vehicle speed information measured by an on-board sensor, and the vehicle transit times are available for the roadside billboard on the road. Estimate of observation duration tobv .
- the duration estimation unit includes: dividing a road into different lanes; obtaining an observable duration t obv of a billboard on the road side of the road through the passing time of the vehicle to obtain all the vehicles on each lane of the current road, thereby obtaining the road
- the total observable duration of the billboard established in sections is ⁇ t obv .
- the salient elements of the image are mined to obtain the best outdoor advertising area from the list of potential candidate locations for outdoor advertising;
- the overall maximum duration of the video advertisement is set to obv / 2.
