Feature-matching based overlay of 7 years of high-resolution imagery collected by the TEMPO ecological module (EMSO-Azores observatory)

the dataset contains raw screenshots retrieved from video sequences collected by the tempo ecological module from 2012 to 2019 at a frequency from infra-daily to 10 days (base of the eiffel tower hydrothermal edifice, lucky strike, mid-atlantic ridge, depth of 1695m). these screenshots were all transformed in a continuous spatio-temporal image reference system. this homography transformation was calculated by a combination of feature-matching algorithm and manual annotation of keypoints. all homography transformation matrices and images transformed are included.the dataset is accompanied with a read me to describe the structure of each data. please contact loïc van audennhaege for further information on the workflow.

该数据集囊括了2012年至2019年间，由Tempo生态模块采集的视频序列中提取的原始屏幕截图，其采集频率介于超日到10天不等（以埃菲尔铁塔水热建筑群、幸运打击点、中大西洋脊以及1695米水深为基础）。所有截图均经过连续时空图像参考系的转换。该同态变换通过特征匹配算法与关键点手动标注的结合进行计算。数据集包含了所有的同态变换矩阵以及转换后的图像。此外，数据集附有说明文件，详细描述了每个数据的结构。如需了解工作流程的更多信息，请联系Loïc Van Audennhaege。
