Fire safety alarm system for high-rise buildings based on machine vision

Due to safety hazards, many residential buildings have restricted the entry of electric bicycles and chargers into the building. However, the phenomenon of electric bicycles entering the elevator in violation of regulations often occurs. This article develops a machine vision based electric bicycle detection and recognition algorithm, which uses the original image of the electric bicycle as input to the neural network and designs a feature extraction algorithm. This algorithm utilizes the external morphological features of electric bicycles to filter out interference and intelligently analyze and accurately distinguish interfering objects. And combined with pressure sensing technology to determine the precise position of electric bicycles in elevators, complete automatic detection and recognition. Embed the algorithm into the internal camera of the elevator, intelligently monitor the electric bicycles inside the elevator, and achieve detection, analysis, and recognition of the electric bicycles. As long as the camera inside the elevator detects that an electric bicycle has entered the elevator, it will immediately issue a warning of "electric bicycles no enter", and the elevator door will remain opening. Only by pushing the electric bicycle out of the elevator door can it operate normally. This function solves the problem of electric bicycles going upstairs in high-rise buildings from the source, greatly reducing safety hazards.
