Saving Depth and Image Data (Stereo ace)#

图像的所有组件都可以各种格式保存为单独的文件。

This may be useful if you want to view the data in a different tool, i.e., point cloud data in a point cloud processing tool, or if you want to share an image with others, i.e., the depth map as a .png file. You can save individual images or a sequence of images.

深度图（颜色和灰度值版本）和强度图像可以保存为 .png 和 .tiff 文件。点云（颜色和强度版本）可以作为 .pcd 和 .ply 文件保存。

An additional benefit of the Save Depth and Image Data command is that it can automatically rotate a point cloud along the x axis by 180° when saving it. This is necessary because many common point cloud processing tools, e.g., MeshLab and CloudCompare, use right-handed coordinate systems, but with the y axis pointing up (the y axis of the Stereo ace camera is pointing down).

Because of this difference in the orientation of the y axis, those tools show point clouds produced by the Stereo ace camera backwards and upside down. To make the point clouds compatible with those tools, they need to be rotated along the x axis by 180°. You can achieve this by selecting the Invert z-axis check box (enabled by default) in the Save Data dialog. The rotation is then done automatically when saving a point cloud to file.

要以不同的格式保存图像数据：

1. 在文件菜单中，单击保存深度和图像数据。
2. In the Save Data dialog, select the image components that you want to save.
3. （可选）选中反转 z 轴复选框。
4. (Optional) Select the Radial Distances check box if you want create range maps instead of depth maps.
5. （可选）如果要将当前相机设置保存在 .pfs 文件中，请选中当前设备设置复选框。
6. 为图像的文件名指定一个命名基准。
7. 指定要保存图像的文件夹。
8. （可选）如果要对图像连续编号，请选中附加序列号。
9. Click Save to save one image or click Save Sequence to save a sequence of images.
