Image Picker¶
This device has two input channels (inputImage and inputTrainid).
inputImageexpects an image stream (e.g. from a camera);inputTrainIdis used to get the timestamps. Its data content is ignored, as only timestamp is relevant.
Images whose trainId equals inputTrainId + trainIdOffset are forwarded
to an output channel, while others are discarded.
