Data files for implementing Space-Time Image Velocimetry (STIV) at the Shimada and Jinshin Bridges

The dataset consists of original files for Space-Time Image Velocimetry (STIV) as described in the corresponding paper. The data is compiled as a zip archive file. You will find two folders, “Shimada Br” and “Jinshin Br”, at the root folder of the zip file. The folders contain datasets for the Shimada Bridge and the Jinsjin Bridge, respectively. Each data file name begins with the bridge name. Descriptions of data files are as follows: 

1) camera parameters.xml: Indicates camera parameters for performing geo rectification.

The first line describes the title of the data
The second line is the focal length.
Lines 3 to 5 are camera position coordinates in meters.
Lines 6 to 8 show the camera angle in order of roll, pitch, and yaw. Unit: radian.
The 9th and 10th lines are the lens principal point positions. Unit: pixel．
The 11th line and below are output data from the calculation software and are not particularly necessary for calculation.

2) cross sectional data.csv: Cross sectional coordinate data.

The first column name shows the transect coordinate and the second column shows the elevation coordinate. Unit: (m). 

3) GRP.csv: Coordinates of Ground Control Points .

The first line shows the label for each column.
1st column: The name of the control point.
2nd to 4th column: the actual coordinates of the control point. Unit: (m).
5th to 6th columns: the screen coordinates of the control point. Unit: (pixel).
Columns 7 to 14: Calculation results of errors in geometric correction. Unit: (m).

4) searching line coordinates.csv: Coordinate data of search line.

1st column: Search line number.
2nd to 3rd columns: Coordinates of the start point of the search line. Unit: (m).
4th to 5th columns: Coordinates of the end point of the search line. Unit: (m).

5) 20xxxxxxxxx water level.csv: Water level of the flood. Unit: (m).

6) 20xxxxxxxxx.avi: Video file used for analysis.

本数据集汇集了空间-时间图像速度测量（Space-Time Image Velocimetry，简称STIV）的原始文件，具体描述如相关论文所述。数据集以ZIP归档文件形式整理。在ZIP文件的根目录下，您将发现“Shimada Br”和“Jinshin Br”两个文件夹，分别包含Shimada桥和Jinsjin桥的数据集。每个数据文件的名称均以桥梁名称开头。以下为数据文件的具体描述：

1) camera parameters.xml：指示进行地理校正的相机参数。

- 第一行描述数据标题。
- 第二行记录焦距。
- 第三至五行提供相机位置坐标，单位为米。
- 第六至八行展示相机角度，依次为翻滚、俯仰和偏航，单位为弧度。
- 第九和第十行提供镜头主点位置，单位为像素。
- 第十一行以下为计算软件的输出数据，对于计算并非必需。

2) cross sectional data.csv：横截面坐标数据。

- 第一列显示横截面坐标，第二列显示高程坐标，单位均为米。

3) GRP.csv：地面控制点坐标。

- 第一行显示每列的标签。
- 第一列：控制点名称。
- 第二至四列：控制点的实际坐标，单位为米。
- 第五至六列：控制点的屏幕坐标，单位为像素。
- 第七至第十四列：几何校正误差的计算结果，单位为米。

4) searching line coordinates.csv：搜索线坐标数据。

- 第一列：搜索线编号。
- 第二至三列：搜索线起点的坐标，单位为米。
- 第四至五列：搜索线终点的坐标，单位为米。

5) 20xxxxxxxxx water level.csv：洪水水位，单位为米。

6) 20xxxxxxxxx.avi：用于分析的视频文件。
