I am currently viewing live data using the viz command in the Ouster SDK. I am aware that it is possible to select an area in the 2D image view (using the right mouse button) and then inspect values such as range.
However, I would like to know if there is also a way to select a region directly within the point cloud view and check the corresponding range (or similar) values. When selecting a region in the 2D view, the result often appears distorted when observed in the point cloud, which makes it difficult to examine specific areas accurately.
If there is an available feature or a recommended workflow for selecting a region in the point cloud view and retrieving measurement values, I would greatly appreciate it if you could share the method.
You can download the latest Ouster Studio v2.3.3. It includes a new feature called Hover Mode (see attached picture), which allows you to view point cloud data simply by hovering your mouse over the points.
I am aware of the Hover mode in Ouster Studio 2.3.3. However, as far as I understand, Hover mode only allows checking point values when the frame is paused, not while the data is streaming. What I am trying to achieve is to monitor the changes of point values in real time, so Hover mode does not fully meet my requirement.
Since the SDK Viz window allows real-time point inspection in 2D, I wanted to ask whether there is a similar capability in the 3D point cloud view as well. It seemed unusual that the feature appears to be available in 2D but not in 3D.
@victo We are working to add this as feature in the OusterCLI/viz but meanwhile you can utilize the ReverseXYZLut described in the post: Projecting a 3d point back into a 2d range image for an Ouster Sensor which allows you to pin point specific points in the 3d and get their (u,v) indices in the range image.
