uint64_t k4a_image_get_timestamp_usec ( k4a_image_t  image_handle )

related

Get the image timestamp in microseconds.

Parameters

image_handle

Handle of the image for which the get operation is performed on.

Remarks

Returns the timestamp of the image. Timestamps are recorded by the device and represent the mid-point of exposure. They may be used for relative comparison, but their absolute value has no defined meaning.

Returns

If the image_handle is invalid or if no timestamp was set for the image, this function will return 0. It is also possible for 0 to be a valid timestamp originating from the beginning of a recording or the start of streaming.
