Surfers Paradise (Video Obs) - Shoreline Observation

Surfers Paradise - Queensland

Data Attributes

5 - 10min video clip
16 - 25 frames per sec
Video format: WMV/H264 codec
640 x 480 pixels or greater

Site Description

Video footage captured by either vertical or horizontal cameras mounted at strategic beachside locations, the Shoreline Detection program processes the frames of the video file to produce timex images, which are then used for the calculation of the shoreline position over time. Once the shoreline has been found on the image, the program uses a set of surveyed points to map image co-ordinates to real world Northing / Easting values.

场地描述

该数据集的视频素材由安装在关键海滨点位的垂直或水平摄影机位拍摄获取。海岸线检测（Shoreline Detection）程序将对视频文件的帧进行处理，生成时序图像（timex images），并利用这些图像计算随时间变化的海岸线位置。在图像中完成海岸线识别后，该程序会通过一组实测控制点，将图像坐标映射至真实世界的北距（Northing）与东距（Easting）坐标系中。
