Timestamps of ZED2i images using ZED2 ROS wrapper

Hello,

I am using ZED 2i with Jetson orin nano devkit running ros2 humble and ubuntu 22.04. I collected static images with VGA resolution at 15 Hz.

I noticed that there is a constant frame drop that happens around ~46 to 50 s. Instead of 67 ms as interval for consecutive images, I see 133 ms. Is this an expected behavior? Is there a way to remove this frame drops or latency?
I attached the following plot. Thanks.

I synchronized the system time of Jetson Orin nano with 1 PPS using chrony.

Hi @ellarizza
Please provide more information regarding your setup.

How are you measuring the framerate?
Are you using the Jetson in MAXN power mode with jetson_clocks running?
Have you applied the recommended system settings?
