Proposal

Hi,
is there a way to record the stereo images, camera info and IMU data with ROS in a ROSBag file and use the SDK+ROSWrapper afterwards to calculate the depth images?

As background:
We like to use the camera for mapping purposes on our robot. So there is no need for a realtime calculation of the depth images and the system also has no CUDA gpu onboard.
There is also no CUDA computer nearby where we could stream the data onto.
We also like to void the svo files because there are multiple sensors and we like to record all of them synchronously in one file.

Thanks and best regards,
ctieben

Hi @ctieben
the ZED SDK accepts as input only data from live connected cameras, SVO files, and network streaming generated by other ZED SDK instances.
The ZED ROS Wrapper is based on the ZED SDK, so it accepts only the same input types and rosbag data cannot be used as input for our node.
