For important camera calibration in the field of computer vision, a new target form, namely, a
grid spherical target (GST) that is different from the spherical target, is proposed. The GST …

A high-accuracy calibration technique using a white paper and a front coating plane mirror is
proposed in this paper for line-structured light vision sensors. This method shows …

Since the GPS is unavailable in underground environment, it is extremely challenging to
measure the speed and location of a metro train. This paper proposes a novel data-fusion …

A novel calibration method for the line-structured light vision sensor that only requires the
image of the light stripe on the target using a movable parallel cylinder target is proposed in …

This paper presents a new, to the best of our knowledge, calibration method for line-
structured light vision sensors. The laser stripe intersecting the cylindrical target and the line …

An extrinsic parameters calibration method of multi-cameras with non-overlapping fields of
view (FOV) using laser scanning is presented. Firstly, two lasers are mounted on a multi …

Small-scale experimental tests were carried out by a bi-disc machine to reproduce the
phenomena occurring in shoe-braked railway wheels. Wheel specimens of three different …

摘要针对线结构光条纹中心提取的效率和精度影响测量结果的问题, 提出一种主成分分析与灰度
重心相结合的方法. 首先对图像进行高斯卷积并采用阈值分割法初步提取图像中有效的光条纹 …

Rolling contact wear/fatigue tests on wheel/rail specimens are important to produce wheels
and rails of new materials for improved lifetime and performance, which are able to operate …

To accurately predict the train operation state through the test results of the scaled vehicle-
track test platform, based on the similarity theory and vehicle-track coupling dynamics …
