Bullet counting method and device, terminal and storage medium

Abstract

The invention discloses a bullet counting method and device, a terminal and a storage medium. The method comprises the following steps: acquiring a to-be-processed sound signal based on a preset sampling frequency, determining a plurality of gunshot signals and a plurality of channel signals respectively corresponding to the plurality of gunshot signals, processing the plurality of channel signalscorresponding to the plurality of gunshot signals into a plurality of digital signals, and performing translation and superposition processing on the plurality of digital signals corresponding to theplurality of gunshot signals for a predetermined number of times to obtain a predetermined number of superposed signals corresponding to the plurality of gunshot signals, determining target positionscorresponding to the plurality of gunshot signals according to the preset threshold value, and performing bullet counting processing. According to the invention, through translation superposition processing, multiple channel signals corresponding to multiple gunshot signals are kept consistent in a time domain, the effect of enhancing signal strength is achieved through superposition processing,jitter caused by noise is counteracted, and the difficulty of determining the target position and the accuracy of bullet counting are also reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a bullet counting method, device, terminal and storage medium. Background technique [0002] At present, in the process of live ammunition shooting in the shooting range, the management of the number of bullets is very important. If there is a discrepancy between the number received and the actual number of shots or the behavior of personnel hiding, it will cause huge security risks. Therefore, it is necessary to count range bullets. [0003] In related technologies, the counting of bullets is often carried out through one-on-one supervision by a special person, manual counting or post-event counting of bullet casings. This counting method has the possibility of misjudgment when multiple people are shooting at the same time or the shooting environment is relatively harsh, and the cost of counting bullets is high due to the reliance on manual labor.
