本发明涉及智能交通技术领域，特别涉及一种经济地理要素后处理分析与挖掘方法及系统。The invention relates to the field of intelligent transportation technology, and in particular, to a method and system for post-processing analysis and mining of economic and geographic elements.
使用量产车辆对区域地图进行众包式采集过程中会收集各类车载传感器数据，其中包含自车视觉与感知数据以及GPS定位数据；一般的，这些数据会用于辅助高精度地图更新、语义地图生成、车辆定位等技术方向，但从视觉传感器获取到的数据本身，能够进一步的进行图像处理、目标识别、语义分割等技术手段，实现对车辆行驶过程中有关经济地理要素信息的初步采集。In the process of crowdsourced collection of area maps using mass-produced vehicles, various types of on-board sensor data are collected, including self-vehicle vision and perception data and GPS positioning data; generally, these data are used to assist high-precision map updates, semantic Technical directions such as map generation and vehicle positioning, but the data itself obtained from the visual sensor can further carry out image processing, target recognition, semantic segmentation and other technical means to achieve the preliminary collection of economic and geographic factor information during vehicle driving.
例如，关于道路中交通流量的统计可以提供交通运输地理信息系统的基本信息，是否该地域为商用车或小型乘用车行驶密集区域；关于道路行人检测的结果能够反馈周边商业地理的区域组织，是否根据行人在不同时间段的出现密度判断该地域属于商业区、住宅区或是工业区；关于道路行驶过程中相机采集到的车辆图像完成型号、品牌的分类与识别，能够辅助区域经济地理完成某一区域的居民经济结构关系等。For example, statistics on the traffic flow on roads can provide basic information of a transportation geographic information system, whether the area is a dense area for commercial vehicles or small passenger vehicles; the results of pedestrian detection on roads can be fed back to the regional organizations of commercial geography Whether the area is classified as a commercial area, residential area or industrial area according to the presence density of pedestrians at different time periods; the classification and identification of the model and brand of the vehicle image collected by the camera during road driving can assist the regional economic geography completion The economic structure of the residents in a certain area.
若需要通过直接进行此类经济地理数据的调研，与高精度地图采集任务类似，需要耗费大量人力、物力，若能结合两种不同种类的生产任务但只通过同一次采集流程，通过众包采集方式存储的传感器数据理论上具备同时完成部分两种任务的能力，从而实现对于高精度地图生成过程与产物的进一步 衍生，最终可缩减部分经济地理数据的调研成本开销。If you need to conduct such surveys of economic geographic data directly, similar to the high-precision map collection task, it requires a lot of manpower and material resources.

图1是经济地理要素后处理分析与挖掘方法流程图；Figure 1 is a flowchart of post-processing analysis and mining methods of economic geography elements;
图2为道路与户外广告牌场景示意图。Figure 2 is a schematic diagram of the road and outdoor billboard scene.
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.
传统意义下，高精度地图采集车或地图众包车辆在执行采集作业时，传感器数据仅用于生成道路路面信息、高程指示牌信息等高精度地图所需元素，但实际上原始传感器数据中包含了诸如户外广告牌、高层建筑、立交桥、人行通道桥等点云或视觉传感器信息，这些信息一般来说并不会参与高精度地图的构建、生产与后期制作。但这一类高精度地图采集中未被后期利用到的原始数据中，会包含与户外广告牌选址、户外广告展板内容物以及动态广告单片最大时长等广告经济效益潜在决定因素的最优化参数。In the traditional sense, when high-precision map collection vehicles or map crowdsourcing vehicles perform collection operations, 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. However, 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.
在车辆在广告牌前通过时间内，选择的广告播放时间长度，根据不同时间车流量完成预测。During the time that the vehicle passes in front of the billboard, the length of time for the advertisement to be selected, and the prediction is completed according to the traffic volume at different times.
地图采集过程中环境感知数据信息内，存在部分未被完全使用到的高程 原始测量数据，例如户外广告牌、高层建筑外表面等空间点坐标与对应的图像数据、激光点云数据。与其间接存在部分相关性的传感器数据，如众包采集车辆的轮速信息、油门踏板与刹车踏板的开合度、当前视觉感知系统中得到的前方车辆(判断不同时间段内的车辆单位时间交通流量或通行密度)，可以量化分析、挖掘出以下几个不同侧重点的经济地理数据分析策略。During the map acquisition process, there are some raw elevation measurement data that are not fully used, such as outdoor point billboards, high-rise building exterior surface coordinates and corresponding image data, laser point cloud data. There are some indirect correlations with sensor data, such as crowd-sourced vehicle wheel speed information, the opening and closing of the accelerator pedal and the brake pedal, and the forward vehicle obtained in the current visual perception system (judging the vehicle unit time traffic flow in different time periods) Or traffic density), you can quantitatively analyze and dig out the following economic and geographic data analysis strategies with different focuses.
第一是现有广告牌的经济效益分析：如图1、2所示，一种经济地理要素后处理分析与挖掘方法，其包括如下步骤：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:
S1、利用环境感知传感器采集当前行驶道路上对于任一地点路侧广告牌的可观测区间的判断，其中包括不影响驾驶员驾驶安全的可观测最近点p
1，以及广告牌内容可见的可观测最远点p
2；
S1. Use an environment-aware sensor to collect the judgment of the observable interval of the roadside billboard on any road on the current driving road, including the observable closest point p 1 that does not affect the driving safety of the driver, and the observable visible billboard content Furthest point p 2 ;
利用采集车自带的环境感知传感器(如相机)可以近似完成当前行驶道路上对于某处路侧广告牌的可观测区间的判断，其中p
1处为不影响驾驶员驾驶安全的可观测最近点，p
2处为广告牌内容可见的可观测最远点。一般的，可观测最近点与可观测最远点的判断依赖于人的主观判断，但实际上通过相机的有限视场角的边际，与最小可分辨的广告牌成像像素尺寸大小，可以量化此处可观测最近点、可观测最远点的技术指标。
Using the environment-aware sensor (such as a camera) that comes with the acquisition vehicle can approximately complete the judgment of the observable interval of a roadside billboard on the current road, where 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. In general, 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.
S2、根据p
1、p
2之间的间距dist，以及车载传感器测量得到的车速信息，获得不同采集时间段内的车辆通过时间，车辆通过时间为该道路路侧广告牌的可观测时长t
obv的估计。户外广告牌应该做到在不影响驾驶安全的前提下，使沿途道路行驶的车辆驾驶员、车内乘员能够更多的注意到广告展板的内容，其直接关联于在道路上的车辆动态行驶过程中可直接观察到此展板的时间长度。
S2. According to the distance dist between p 1 and p 2 and the vehicle speed information measured by the on-board sensor, 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.
在本发明所述的经济地理要素后处理分析与挖掘方法中，In the post-processing analysis and mining method of economic geographic elements according to the present invention,
对于众包采集而言，通过基本假设“特定众包车辆周边实时车流交通密度在不同时间段内基本稳定”，所述步骤S2包括：将道路划分为不同的车道；通过车辆通过时间为该道路路侧广告牌的可观测时长t
obv的估计，获得当前道 路各个车道上的所有行驶车辆，从而获得此道路分段设立的广告牌的总体可观测时长∑t
obv。
For crowdsourcing, based on the basic assumption "the real-time traffic density around a specific crowdsourced vehicle is basically stable in different time periods", 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 Σt obv of the billboard established on this road segment.
第二是在当前区域道路行驶途中潜在可布设户外广告的候选位置：在本发明所述的经济地理要素后处理分析与挖掘方法中，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,
确定当前行驶道路临近区域内安全驾乘的可视区域，通过道路分段寻找潜在的候选高程空间；Determine the visible area for safe driving in the vicinity of the current road, and search for potential candidate elevation spaces by road segmentation;
所述候选高程空间包括“可用于设置广告的最优区域”与“其他次优区域”、“较差广告效果区域”。需要通过总体可观测时长的排序来确定其中最优区域。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.
“候选高程空间”表现的是未经过任何筛选的所有可选区域，还需要结合不同道路分段来确定不同候选高程空间的观测时长，以此评估潜在的候选位置列表。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.
针对不同道路分段获得不同道路分段对应的∑t
obv；按照总体可观测时长排序来确认潜在的、可布设户外广告的候选位置列表。
Obtain Σt obv corresponding to different road segments for different road segments; sort according to the overall observable duration to confirm a list of potential candidate locations for outdoor advertising.
在本发明所述的经济地理要素后处理分析与挖掘方法中，In the post-processing analysis and mining method of economic geographic elements according to the present invention,
通过分析人类视觉关注度、视觉传感器历史数据中挖掘图像显著性要素从潜在的、可布设户外广告的候选位置列表获得最佳户外广告区域。By analyzing the human visual attention and historical sensor data, 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.
由于人眼结构导致人在观察动态目标时，只有被关注目标附近的小范围区域能够被赋予清晰的分辨率，其他部分则不能被有效的赋予视觉注意力、以低精度呈现。对人类视觉系统进行分析、统计关注区域分布的过程即为显著性检测。Due to the structure of the human eye, when viewing a dynamic target, only a small area near the target of interest can be given a clear resolution, and other parts cannot be effectively given visual attention and presented with low accuracy. The process of analyzing the human visual system and statistically distributing the areas of interest is the significance detection.
因此，在满足车辆驾驶安全的条件下，让户外广告区域能够得到较高视觉关注度、显著性与持续可关注时长，即是量化人类主观感知最佳广告区域的技术指标。Therefore, in order to meet the conditions of vehicle driving safety, 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.
又由于在不同时段对应了不同交通流量，而不同交通流量对应了车辆行驶的自车车速。与自车车速直接关联的是在特定车道能够有效观察特定区域 的最大时长。因此，需要大量收集视觉传感器历史数据进行分析和挖掘。Because different traffic flows correspond to different time periods, different traffic flows correspond to the speed of the vehicle. Directly related to the vehicle speed is the maximum length of time that can be effectively observed in a specific lane in a specific lane. Therefore, a large amount of historical data of vision sensors needs to be collected for analysis and mining.
在本发明所述的经济地理要素后处理分析与挖掘方法中，In the post-processing analysis and mining method of economic geographic elements according to the present invention,
通过分析车内乘员可查看到的广告画面时长，确定平面广告、视频广告的种类。By analyzing the length of the advertisement screen that can be viewed by the occupants in the car, the types of print advertisements and video advertisements are determined.
第三是确定广告展板使用的广告类型是平面或动态，动态广告的最佳播放时长：在本发明所述的经济地理要素后处理分析与挖掘方法中，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,
在为视频广告时，将视频广告的整体最大时长设置为t
obv/2。
When it is a video advertisement, the overall maximum duration of the video advertisement is set to obv / 2.
分析车内乘员可查看到的广告画面时长，确定平面广告、视频广告的种类，在分析策略中可根据t
obv进行确认，若在某一时间段内交通流量过于密集，例如早晚出行高峰时段，或这一路段行驶的车辆以大型商用车为主，那么此处或此时间段适宜平面广告为主的投放策略，原因是车辆驾驶员若过于关注户外广告展板，则可能会产生影响道路交通安全的行为，此时户外广告应当更适宜展现单独的静态平面广告；同样的，t
obv反映了在经过此处道路的车辆平均可查看广告展板的具体时间长度，若能够让车辆驾驶员或车内乘员看到完整的一次动态视频广告，则该广告的整体最大时长应该在“t
obv/2”，才能保证该视频广告被通过该道路的车辆内乘员完整观看。
Analyze the length of the advertising screens that can be viewed by the occupants in the car, determine the types of print ads and video ads, and confirm in the analysis strategy based on tobv . If the traffic flow is too dense in a certain period of time, such as morning and evening peak hours, Or the vehicles driving on this section are mainly large commercial vehicles, then the print strategy based on print ads is suitable here or during this period, because if the driver of the vehicle pays too much attention to outdoor advertising boards, it may affect road traffic safety. At this time, outdoor advertising should be more suitable for displaying a separate static print advertisement; similarly, tobv reflects the specific length of time that vehicles passing through the road on this road can view the advertising display board on average. When the occupant sees a complete dynamic video advertisement, the overall maximum duration of the advertisement should be "t obv / 2" to ensure that the video advertisement is completely viewed by the occupants of the vehicle passing the road.
对于t
obv，可根据历史上广告供应商的投放数据进行统计分析，以便确认其不影响道路交通安全的阈值上限，即最长观测时长。
For tobv , 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.
对于不同采集时间段，一般的会存在不同的道路交通流量或车流密度，进而导致不同的车速信息估计，综合考虑而言，可以估计出每天不同时刻的t
obv，若想完整的使行驶车辆观测到整个动态广告，则广告时长应当存在上界t
obv以及下界t
obv/2，也就是正好在行驶过程中，车辆中人员可以观测完整的动态视频广告的时间长度。在这一时长范围的指导建议下，可以更为合理的安排不同时间段内的广告播放形式，以换取最大的经济效益。
For different collection time periods, there will generally be different road traffic flow or traffic density, which will lead to different vehicle speed information estimation. In overall consideration, you can estimate the tobv at different times of each day. If you want to fully observe the driving vehicle To the entire dynamic advertisement, 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.
