The invention discloses a real-time
noise reduction enhancement method for an
ultraviolet Raman spectrum
system, and belongs to the field of spectrum detection and spectrum
processing technologies andsignal
processing. The method comprises: collecting
ultraviolet Raman signals in real time, counting the collected Raman
signal data, predicting the effective
peak value of the Raman signals, and theeffective
peak value comprising an effective valley and a top peak;
processing each frame of collected Raman spectrum; aiming at each frame of Raman spectrum, segmenting each frame of Raman spectruminto blocks through the obtained effective troughs, respectively judging the attributes of the segmented blocks, the attributes of the regions refering to the attributes of
noise regions or the attributes of effective Raman
signal regions, filtering the
noise regions, and then splicing the Raman
signal regions and the filtered noise regions; and then, splicing the processed N + 1 frames of spectrums along a time axis to form a 2D image, filtering the 2D image through an iterative bilateral filtering method, and superposing and normalizing the N + 1 spectrums along the time axis after filteringto obtain a Raman spectrum subjected to
noise reduction processing.
