Hello,
I can use api “dwSensorCamera_getImageNvMedia” to get the dwImageNvMedia,then I can get the timestamp of camera.Do you know what’s the real meanings of timestamp in dwImageNvMedia. When is this time set,and is it set by Aurix or Tegra?

Thanks

Dear denglong,

Could you refer to below and Sensor Data Timestamping part in DriveWorks Development Guide.pdf for your topic? Thanks.

Sensor Data Timestamping
One of the critical aspects of data acquisition on systems with multiple sensors for real-time processing is to
obtain accurate timestamping of the data. DriveWorks relies on the system time source of Tegra, in particular,
the CLOCK_MONOTONIC time source.
