Wind Turbine Blade SfM Image Capturing Setups

The dataset contains 18 image datasets of a wind turbine blade section in an outdoor environment that are used for SfM reconstruction. The images are separated depending on the image capturing setup. The different setups are as follows: - Distance from camera to blade - 2m, 4m, 6m - Horizontal image overlap - number of images taken in a semi-circle around the wind turbine blade in vertical direction - 9, 17, 33 images - Vertical image angle change - number of bands of images, where the height is changed - each band contains an additional semi-circle of horizontal images - 1 or 2 vertical bands Images are taken with a Canon 6D DSLR camera and each image contains EXIF data about the camera settings used to capture it. From the 18 image datasets, 15 were reconstructed correctly using Agisoft Metashape and the resultant 3D meshes are added in .obj format. In addition, a horizontal 2D slice is taken from each 3D reconstruction for testing the captured blade's overall shape.本数据集包含18组适用于运动恢复结构（SfM, Structure from Motion）重建的户外场景风力涡轮机叶片截面图像数据集。所有图像按照拍摄配置进行分组，不同拍摄配置参数如下： 1. 相机与叶片的拍摄距离：2米、4米、6米 2. 垂直环绕半圆的图像数量：在垂直方向上环绕风力涡轮机叶片拍摄的半圆图像数量，取值为9、17、33张 3. 垂直波段数量：即拍摄高度发生变化的图像波段数，每个波段包含一组额外的水平半圆拍摄图像，波段数可选1或2 所有图像均采用佳能6D（Canon 6D）数码单反相机拍摄，每张图像均附带记录拍摄所用相机参数的EXIF元数据。在上述18组图像数据集中，有15组可通过Agisoft Metashape软件完成精准重建，生成的三维网格模型以.obj格式存储。此外，还从每一组三维重建结果中提取了水平二维切片，用于对所拍摄叶片的整体外形进行测试验证。
