@tbolten Hi, thanks for your questions. The following are the responses.
1) Generation of the EventAccumulatedPic
The raw data obtained using getEventDataVector
does not remove the Fixed Pattern Noise(FPN).
However, in the data directly obtained from interface getEventPicMat
, this noise has been removed already.
2) Comparison with the threshold
The threshold does not indicate the gray value, and there is a complex correspondence between them (hardware related). You can not compare the gray value difference with the threshold to determine whether the pixel should be triggered.
In a certain time interval, a pixel may be triggered multiple times, and it has a corresponding brightness/gray value at each triggering time. In EventDataVector
, it contains all the triggered gray values during this time interval. However, in EventAccumulatedPic
, only the latest triggered gray value at each pixel location is retained. So your comparison method for these two data type is incorrect.
Thanks again. Please feel free to contact us if you have any further questions.
