Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0023] It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.

[0024] In the existing technical solutions, the signals of each detection coil set in the object detection equipment are independently processed, and the correlation between the signals of each detection coil is ignored, thereby losing part of the information, resulting in a low signal-to-noise ratio In some cases, the signal cannot be processed effectively. In the embodiment of the present invention, a new detection signal processing method is propos...

Abstract

The invention provides an article detection method and device, a storage medium and an electronic device. The method comprises that induction signals of at least two adjacent detection coils arrangedin the article detection device are obtained; the correlation degree between the induction signals is obtained; and if the correlation degree is beyond the present threshold range or lower than a preset threshold, it is determined that there is a target article in the detection range of the article detection device. The problems that a preset type of article cannot be detected and the detection efficiency is low in the related art can be solved, it is ensured that the preset type of article can be detected, and the detection efficiency is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to an object detection method, device, storage medium and electronic device. Background technique [0002] The working principle of conventional item detection equipment (for example, electromagnetic induction security gate) is: the detection equipment is mainly composed of a transmitting coil, multiple detection coils, signal acquisition equipment and other equipment; the role of the transmitting coil in the high-frequency alternating current Next, an alternating magnetic field is generated in the space within the range of the door frame; the alternating magnetic field in the space excites the detection coil to generate an alternating current, and the electrical signal on the detection coil is collected by the signal acquisition device; when no metal objects pass through the security gate, The alternating magnetic field in the space is stable, and the signal of the detection coil ...
