hi,

I am using isaac ros vslam on jetson and with zed2i camera. however I get this warning:

[visual_slam_node]: Delta between current and previous frame [100.511000 ms] is above threshold [100.000000 ms]

what are the reasons for this message and how is it possible to avoid it?

Hi @javadb1024

The issue may be related to your hardware not providing enough time to the Isaac ROS vslam node, which triggers this warning.

Please check that the camera satisfies the requirements Isaac ROS Visual SLAM — isaac_ros_docs documentation

Also, check if your hardware has enough power, GPU, and GPU memory to run the ZED SDK and Isaac ROS vSLAM.

Best,
Raffaello
