保存深度和图像数据#
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 blaze camera is pointing down).
Because of this difference in the orientation of the y axis, those tools show point clouds produced by the blaze 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:
- 在文件菜单中,单击保存深度和图像数据。
- In the Save Data dialog, select the image components that you want to save.
- (可选)选中反转 z 轴复选框。
- (Optional) Select the Radial Distances check box if you want create range maps instead of depth maps.
- (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。
- 为图像的文件名指定一个命名基准。
- 指定要保存图像的文件夹。
- (可选)如果要对图像连续编号,请选中附加序列号。
- Click Save to save one image or click Save Sequence to save a sequence of images.
