Embodiment Construction

[0071] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0072] The biggest problem with using ordinary cameras to identify fires is that it is easy to identify some red or yellow lights as fires, causing false alarms. In order to solve this problem, the embodiment of the present invention mainly grasps two characteristics of fire: (1) fire is usually accompanied by smoke, and (2) the combustion of fire is a dynamic process. In...

Abstract

The invention discloses a fire identification method and device and relates to the technical field of computers. A specific embodiment of the method comprises the following steps of acquiring continuous frames of images from a video; the trained neural network being adopted to calculate the state probability of each frame of image so that an initial state sequence is obtained; calculating a transition state sequence with the maximum joint probability according to a probability transition matrix and the initial state sequence; wherein each element in the probability transition matrix represents the probability of state transition from a previous frame of image to a next frame of image, and the transition state sequence represents the state probability of each frame of image after state transition; and judging whether a fire risk exists or not according to the transition state sequence with the maximum joint probability. According to the method a technical problem that a common camera is low in fire recognition accuracy can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a fire identification method and device. Background technique [0002] At present, the identification of fire mainly relies on smoke detection equipment, or the use of cameras with infrared devices to judge whether there is a fire by fusing temperature and images. However, the disadvantage of smoke detection equipment is that the fire can only be detected after the fire has reached a certain level; the disadvantage of cameras with infrared devices is that the equipment needs to be customized, and it is strongly bound to the software algorithm, which has poor versatility and needs to be rearranged Only customized cameras can use this technology, and existing ordinary cameras cannot be reused, resulting in high modification costs. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [000...
