Electromagnetic shielding type intelligent mower boundary inside and outside identification method based on DTW algorithm

The invention discloses an electromagnetic shielding type intelligent mower boundary inside and outside identification method based on a DTW algorithm. According to the method, normal and effective signal library members are determined under the condition that no background noise is recorded, internal and external classification and marking are carried out, and an intelligent mower inductance probe periodically collects induction current signals and carries out time domain feature value extraction on the induction current signals; secondly, background noise suppression is carried out on the induction current signals, approximate effective signal waveform fragments are intercepted, and sorting and merging are carried out; and finally, based on a DTW algorithm, realizing matching value calculation of the approximate effective signal waveform segments and a normal effective signal library, and searching an optimal reference signal by combining the time domain characteristic values of the segments and the matchin
