I've been using Open3D for some of my 3D work and I love the software. But I am still fairly new to it. I don't know if this question is simple but I would appreciate any guide and help on implementing it. I am trying to generate a 3D BoundingBox in a PointCloud with respect to a 2D Segmentation mask of my original RGB image (PointCloud being created from an RGB-D image). For example, I have the following RGB-D image and a segmented object mask: These are the steps of what I'm thinking of doing: 1. Create an RGBDImage object with the create_from_color_and_depth function. 2. Create a PointCloud object with RGBDImage with the create_from_rgbd_image function. 3. Create a Vector3dVector object from the list of points with respect to the 2D object mask. --> This is mainly the part I don't know how to do. 4. Generate an AxisAlignedBoundingBox from the Vector3dVector object using the create_from_points function. 5. Visualize the BoundingBox and my PointCloud using the visualization.draw. Thes
