Hello,
We are looking for a way of getting the timestamp from the sensor using the SIPL Framework.
The documentation states that there’s metadata containing the timestamp:
https://docs.nvidia.com/drive/drive-os-5.2.6.0L/drive-os/DRIVE_OS_Linux_SDK_NGC_Development_Guide/baggage/structnvsipl_1_1INvSIPLClient_1_1ImageMetaData.html#a906ce3200cec23bcb4c31ae70b499a3e
This has the following structure:
typedef struct DevBlkCDIFrameTimestamp {
/**
* Holds a flag which indicates if the frame timestamp from the sensor is valid. */
NvMediaBool frameTimestampValid;
/**
* Holds the sensor frame timestamp value. */
uint64_t frameTimestamp;
} DevBlkCDIFrameTimestamp;
But the frameTimestampValid is false for each frame.
Then there are other timestamps coming with the SIPL buffer, but my understanding is that those timestamps relate to the time when the image is retrieved by the VI, or the board capture subsystem. We need the time when the pixels were read at sensor level.
I want to know if:
- It’s possible to get a valid
frameTimestampfrom the structure above. - There’s another way of getting the sensor timestamp.
More information: I have tested this with the IMX390 module
