In this paper, an external parameter calibration method for multiple cameras with non-
overlapping fields of view (FOVs) using a laser rangefinder (LRF) is presented. The …

Subsidence and geometry deformation monitoring are essential for safe transportation on a
high-speed railway. Terrestrial laser scanning (TLS) is able to collect dense three …

磨损后的钢轨轨头轮廓极不规整, 传统钢轨磨耗计算方法无法准确表征磨损后的钢轨轮廓全貌.
最新轨道检测车采用激光摄像技术, 实现了钢轨轮廓连续在线检测. 本文提出在现有的轨道检测 …

When a train is running on uneven or curved rails, it generates violent vibrations on the rails.
As a result, the light plane of the single-line structured light vision sensor is not vertical …

A patrol type of surveillance has been performed everywhere from police city patrol to
railway inspection. Different from static cameras or sensors distributed in a space, such …

With the rapid development of high-speed railway, the safety of railway becomes extremely
important. Video is a direct and effective manner for monitoring railway environment, but it is …

Structured-light three-dimensional (3D) vision measurement is currently one of the most
common approaches to obtain 3D surface data. However, the existing structured-light …

In this paper, we present a method of detecting the rail track bends and flaws. Different from
the traditional machine-vision based methods which analyze the images of the rail surface …

Os gestores de infraestruturas dispõem de um número crescente de informação em bases
de dados resultantes dos processos de inspeção automatizados. Estas constituem uma …
