路況前景圖像系統(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 鐳射斷面儀 vehicle or together with a 可攜式鐳射斷面儀.

公路路側資產

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..

除了朝向正前方的攝像機,還可安裝額外的朝向後方的攝像機,拍攝反向車道的全部標識牌,從而不必在同一公路往返兩次檢測。

捕捉

檢測車輛的某個車輪上安裝一套里程計,通過控制電子電路以固定間隔激發攝像機進行拍攝。圖像的拍攝間隔可由用戶自定義,典型數值是5米或10米。這使得檢測車輛能夠跟隨交通車流的行駛速度(每5米拍攝一個圖像,車速可達135km/h。)路況前景圖像系統ROW可自由選擇配置攝像機使用,因此適用於很多具體應用場景。在典型配置下,每隔5米可輸出解析度為1920 x 1200像素,24位元組顏色的圖像。系統用時間和行駛距離標記拍攝的圖像,可立即在筆記本電腦獲得圖像並壓縮存儲。格林伍德工程公司也能加裝一個外部GPS接收器和天線,用戶可以輕鬆地定位拍攝圖像的位置。任何GPS接收器(輸出為1PPS)都適用本系統。

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.

通過座標,圖像可以添加到任何GIS地理資訊系統。

多個攝像機

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

全部攝像機用戶都可自選。攝像機安裝在可調的支架上,拍攝角度可調,並能靈活拍攝遠處的小標識牌。 

攝像機能安裝在檢測車頂部獨立的保護殼內,拍攝時更具靈活度;也可安裝在車輛內部,能最大程度保護攝像機。
