路况前景图像系统(ROW

ROW Imaging is a system designed for collection of digital images from a vehicle. The images are taken at fixed distance or timed intervals, regardless of the speed of the recording vehicle. This way, the roadside inventory can be documented.

The system can be operated as a standalone system or integrated with other equipment as part of a TSD or 激光断面仪 vehicle or together with a 便携式激光断面仪.

公路路侧资产

Signs and other roadside inventory disappear or become damaged in many ways. Manual recordings on the road have a number of disadvantages. ROW Imaging provides permanent documentation in sufficient quality to prevent misidentification. By comparing the current images with images from the previous recording, side-by-side, differences are easy to spot..

除了朝向正前方的摄像机,还可安装额外的朝向后方的摄像机,拍摄反向车道的全部标识牌,从而不必在同一公路往返两次检测。

捕捉

检测车辆的某个车轮上安装一套里程计,通过控制电子电路以固定间隔激发摄像机进行拍摄。图像的拍摄间隔可由用户自定义,典型数值是5米或10米。这使得检测车辆能够跟随交通车流的行驶速度(每5米拍摄一个图像,车速可达135km/h。)路况前景图像系统ROW可自由选择配置摄像机使用,因此适用于很多具体应用场景。在典型配置下,每隔5米可输出分辨率为1920 x 1200像素,24字节颜色的图像。系统用时间和行驶距离标记拍摄的图像,可立即在笔记本计算机获得图像并压缩存储。格林伍德工程公司也能加装一个外部GPS接收器和天线,用户可以轻松地定位拍摄图像的位置。任何GPS接收器(输出为1PPS)都适用本系统。

Synchronised data

Post processing software synchronises each image with other measurements made in the same vehicle based on the high precision odometer tags. This could be information such as road profile and crack detection.

通过坐标,图像可以添加到任何GIS地理信息系统。

多个摄像机

ROW Imaging supports multiple cameras. The number, type and placement of cameras can be selected or changed after purchase.

全部摄像机用户都可自选。摄像机安装在可调的支架上,拍摄角度可调,并能灵活拍摄远处的小标识牌。 

摄像机能安装在检测车顶部独立的保护壳内,拍摄时更具灵活度;也可安装在车辆内部,能最大程度保护摄像机。
