Parameters
  • data: Moves data to internal buffer
function
std::chrono::time_point< std::chrono::steady_clock, std::chrono::steady_clock::duration > getTimestamp()
Retrieves timestamp related to dai::Clock::now()
function
std::chrono::time_point< std::chrono::steady_clock, std::chrono::steady_clock::duration > getTimestampDevice()
Retrieves timestamp directly captured from device's monotonic clock, not synchronized to host time. Used mostly for debugging

Sets image timestamp related to dai::Clock::now()
function
void setTimestampDevice(std::chrono::time_point< std::chrono::steady_clock, std::chrono::steady_clock::duration > timestamp)
Sets image timestamp related to dai::Clock::now()
function
int64_t getSequenceNum()
Retrieves image sequence number
function
void setSequenceNum(int64_t sequenceNum)
Sets image sequence number
function
span< const uint8_t > getRecordData()
function
dai::VisualizeType getVisualizationMessage()
Get visualizable message
Returns
Visualizable message, either ImgFrame, ImgAnnotations or std::monostate (None)
function
DEPTHAI_SERIALIZE(Buffer, sequenceNum, ts, tsDevice)
