文档目的
本文档旨在，指导相关人员，在项目测试前，或项目开局前，对现场进行工程勘察，为后续实际应用效果
作保障。前者需选取合适的点位进行测试，保证达到较好的测试效果；后者针对需要安装的点位进行工勘，
制定合适的工程方案，保证满足客户要求。

电警介绍
2.1
电警摄像单元功能
(1) 能够捕获经过路口某一方向的所有车辆，前端电子警察不仅行使卡口功能，对过往车辆进行
抓拍，对车牌、车型、车身颜色进行识别。同时行使违章检测功能，对违章车辆进行抓拍，
并保存和上传违章记录；
(2) 能够检测或识别出当前红绿灯状态；
(3) 电警支持的违章检测类型包括：闯红灯、逆行、压单/双黄线、压线、压停止线、越线（违章
变道）、未按车道行驶、违章左转、违章右转、违章直行、专用车道（公交车道和非机动车
道）、违章停车、倒车、违章掉头等。
2.2
电警安装位置要素
(1)
(2)
(3)
(4)
不论哪款摄像单元，最合适的安装位置都是位于监控场景中间的正上方；
2MP和3MP相机推荐监控两个车道，5MP、6MP和7MP推荐监控三个车道。
电警摄像单元一般安装在交通路口，抓拍车辆尾部，采用F杆或者龙门架；
电警安装方案中仅有LED频闪灯，不需要安装爆闪灯，推荐方案是每个车道配备一个LED灯，
要求每个LED灯安装位置距离摄像单元1.6米，分别在摄像单元左右两边进行排列。
(5) 具体安装方法详见《ITS V500R001 电子警察工程安装指导书V1.8》。

工程勘察
3.1
现场勘察关注点
现场工程勘察前首先要了解工程概况，包括：项目背景、规模、质量目标、项目开竣工时间；认真研究招
投标文件、工程合同、设计方案和图纸等资料。到达现场后可根据以上工程建设信息进行勘察，了解现场
的实际情况，再结合客户的实际布点需求，确定建设的具体位置。
工勘关注点如下：
(1) 不规则路口：电警摄像单元安装的理想环境是正交十字和T字路口，尽量避免环形路口、Y型
路口等不规则路口。不规则路口可能会导致车道弯曲（影响违章判定），停车线倾斜（影响
违章判定和抓拍位置），车辆（尾部车牌）倾斜（影响车牌识别），无法看清对面红绿灯等
情况；
(2) 道路方向：东西向道路在一天中受阳光照射角度不同，容易出现强逆光、强顺光现象，导致
车牌识别率降低和整体画面效果变差；售前测试中选择点位时需要特别注意该项，在条件允
许下尽量选择南北向安装电警摄像单元；
(3) 硬件环境：选供电、光纤、施工等方便的路口；
(4) 遮挡：路面平整，视野开阔，保证摄像单元、补光灯等设备不被道路指示牌和导向牌、树木
等遮挡；
(5) 停止线距离不一致：尽量避开，不同车道停止线位置不一致的路口，此类路口无法很好兼顾
各车道停止线与下边缘距离和红绿灯；
(6) 绿化带不能立杆：在工堪时，需要确定可立杆范围，这点很重要，会影响方案确定；
