Abstract

The invention discloses an image recognition technology-based forest fire automatic monitoring and recognition system and method, and belongs to the field of image processing. Based on the characteristics of wide application range and high economy of video monitoring image processing and mode recognition technologies, the image recognition technology-based forest fire automatic monitoring and recognition system and method are applied to the field of forest fire monitoring and early warning. The image recognition technology-based forest fire automatic monitoring and recognition method comprisesthe following steps: performing preprocessing of image noise reduction and data compression by using median filtering and gray processing methods; detecting a moving target in the monitoring image byusing a Gaussian mixture background model and a differential detection technology; extracting multi-dimensional features such as color moment, energy, entropy, inverse difference moment and circularity from the detected target image, and fusing the multi-dimensional features into a normalized feature vector; and finally, using a binary classifier of a support vector machine for identification andjudgment. According to the image recognition technology-based forest fire automatic monitoring and recognition system and method, a moving target appearing in a complex background can be well detected, and characteristic parameters are extracted for identification, and automatic fire identification is further realized, and the image recognition technology-based forest fire automatic monitoring and recognition system and method have the advantage of high monitoring accuracy.

Description

technical field [0001] The invention relates to a forest fire automatic monitoring and recognition system and method based on image recognition technology. Background technique [0002] In order to reduce the loss of forest fires, the monitoring and early warning technology of forest fires has become a research topic that countries all over the world pay close attention to. The traditional fire monitoring methods are smoke, temperature, photodetectors and infrared radiation detection, as well as satellite monitoring which is more popular now. For large space fire monitoring such as forest, this paper proposes a fire monitoring method based on image visual features. [0003] With the rapid development of science and technology, various emerging technical means, such as satellite remote sensing, smart sensors, unmanned aerial vehicles, infrared detection and other technologies are gradually being applied to the field of forest fire monitoring and early warning. Traditional ma...
