Title:

DETECTION METHOD AND DEVICE, STORAGE MEDIUM, AND PROCESSOR

Document Type and Number:

WIPO Patent Application WO/2020/103402

Kind Code:

A1

Abstract:

A detection method and device, a storage medium, and a processor. The detection method comprises: using a sensor for emptily scanning to obtain a first output electric signal, and performing feedback correction on the first output electric signal to eliminate the noise to obtain first correction data; using the sensor for scanning a correction sample to obtain a second output electric signal, and performing feedback correction on the second output electric signal to eliminate the noise to obtain second correction data; calculating, according to the first correction data, the second correction data, and a predetermined electric signal value, to obtain third correction data; using the sensor for scanning an object to be detected to obtain a third output electric signal; and correcting, according to the first correction data and the third correction data, the third output electric signal. In each detection process, an electric signal obtained by scanning an object to be detected is corrected in real time so as to obtain the accurate detection result.
