Iam trying to do multi camera calibration with two ensenso C57 camera . for now i have saved camera file for testing . Is it possible to do multi camera calibration in Nxlib in saved camera file . Also workspace calibration in Nxlib sdk . After the calibration how do i get merged depth or colordepointcloud as pcd format . Can i able to capture
the same NxLib commands used to calibrate real cameras can be used on file cameras as well. Please check out our guides on camera calibration and workspace calibration for details and code examples.
Should you have any further questions, please do not hesitate to ask.
I did the multi camera setup and its linked to one camera to another . how do i capture merged pcd and save it as one single pcd . From Nxlib Its difficult to see the merged data and save it . How can I do that ?
Could you please clarify exactly what you want? Here are two possible interpretations I can offer an answer to:
An unstructured point cloud containing the matched 3D points from multiple cameras
This is currently not possible. You can use SaveImage and save one PCD for each camera’s point map and merge them afterwards. Or you can use SaveModel with the PointCloud parameter, but that currently only works for PLY files, although we are in the process of extending it to PCD (issue #6285).
A structured point map containing the matched 3D points from multiple cameras
This can be achieved by saving the result of the RenderPointMap command.
I have two c57 camera here . these two calibrated by link calibration stereo of one camera is linked to another . in SDk i could see the mesh . i would like same mesh in merged format as pcd ?
This is not possible with the current release, but I have send you a download link for a preview which implements PCD output for the SaveModel command, which I expect to give you what you are looking for.
If the preview does not solve your issue or if you have any further questions, please let me know.
