The application provides a detection method, a detection device, a storage medium, and a processor. The detection method comprises the steps of: performing idle scanning by using a sensor to obtain afirst output electrical signal, and performing feedback correction on the first output electrical signal to eliminate noise to obtain first corrected data; scanning a corrected proof by using the sensor to obtain a second output electrical signal, and performing feedback correction on the second output electrical signal to eliminate noise to obtain second corrected data; performing calculating according to the first corrected data, the second corrected data, and the predetermined value of the electrical signal to obtain third corrected data; scanning a tested object by using the sensor to obtain a third output electrical signal; and correcting the third output electrical signal according to the first corrected data and the third corrected data. According to the detection method, the electrical signals obtained by scanning the object to be tested are corrected in real time during each detection process, thereby obtaining an accurate detection result.
Description
technical field [0001] The present application relates to the detection field, in particular, to a detection method, a detection device, a storage medium and a processor. Background technique [0002] Making specific magnetic information or thickness information on banknotes, bills, securities and other media has become an important means of modern anti-counterfeiting. The demand for sensors is increasing, and the requirements for scanning quality are getting higher and higher, but The sensor will be affected by various external environments such as temperature, humidity, and hysteresis during work. Without effective compensation and elimination, the scanned image will appear saturated with stripes and other phenomena, which will deteriorate the quality of the scanned image and affect the recognition and authentication. Pseudo has a big impact. [0003] Most of the existing sensor correction methods are power-on correction, or manual correction according to needs, so that t...
