Anti-false-triggering method and devicefor motion detection,equipment and storage medium

Abstract

The invention discloses an anti-false-triggering method for motion detection. The method comprises the following steps: acquiring the PIR amplitude; judging whether there is at least one PIR amplitude greater than any amplitude in a preset first amplitude interval and at least one PIR amplitude less than any amplitude in a preset second amplitude interval in a preset time interval or not; if yes, triggering a motion detection system to perform motion detection on the moving object; and if not, not triggering the motion detection system to carry out motion detection. The embodiment of the invention further discloses a false triggering prevention device for motion detection, equipment and a storage medium, and the situation that in the prior art, false triggering occurs in a PIR motion detection system is effectively reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, equipment and storage medium for preventing false triggering of motion detection. Background technique [0002] The current PIR motion detection system is composed of a Fresnel lens and an infrared pyroelectric sensor. The Fresnel lens has two functions: one is to focus the infrared rays in the detection area on the detection surface of the sensor; The area is divided into several "bright areas" and "dark areas" (such as figure 1 shown); while the infrared pyroelectric sensor is composed of two pyroelectric electrodes connected in series, and the polarization directions of these two electrodes are just opposite, and the ambient background radiation has the same effect on the two pyroelectric electrodes, which leads to The discharge effects generated during the state cancel each other out, and the detector has no signal output. Once a person walks thr...

Problems solved by technology

Due to the large size of the human body and the regularity of the walking process, the whole walking process will continuously and alternately pass through the "bright area" and "dark area", and each time passing through these two areas will form a pair of positive and negative pulses, but In real life, there are children or some adults who are small in size, walk irregularly, or local strong light and air flow cause unstable heat flow, which makes the PIR motion detection system often trigger falsely.
