Problems solved by technology

Among them, based on the band-pass or low-pass filtering method, the components of these frequency bands in the digital signal itself will also be filtered out, which will cause a large loss in the digital signal and affect the accuracy of later analysis; the morphological filtering method is very Depending on the selection of the length of its structural elements, the versatility is not strong

Abstract

The invention provides a method and device for generating a baseline drift curve, belonging to the field of data signal processing. The method includes: step 1, sampling the signal to obtain a digital signal curve to be processed, the digital signal curve includes a periodic target waveform, and the target waveform includes a waveform of a characteristic signal or a waveform of a plurality of characteristic signals Step 2, calculating the energy center of gravity of each target waveform; Step 3, constructing a sequence of energy center of gravity points according to the energy center of gravity of each target waveform; Step 4, generating a baseline drift curve based on the sequence of energy center of gravity points. By adopting the present invention, the correction of baseline drift can be completed quickly, and it is suitable for application environments with relatively strict requirements on computing speed and power consumption, and can quickly complete accurate and reliable signal correction.

Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to a method and device for generating a baseline drift curve. Background technique [0002] Digital signals with periodic typical wave groups are often used in various analysis, but in the process of signal measurement, the signal baseline drifts due to the interference of the measurement object, environment and instruments, which affects the accuracy of the analysis results, so it is necessary to eliminate the signal Baseline drift. Human pulse wave and ECG signal are common human physiological signals used for human health monitoring or disease diagnosis and treatment. They are also signals with periodic typical wave groups. There will also be a problem of signal baseline drift, which needs to be eliminated. [0003] For example, the electrocardiographic signal is applied to the diagnosis of heart disease after being detected and recorded by the instrument, which records ...
