Abstract

The invention discloses a forest rocket detecting and identifying method and apparatus based on the video image intelligent analysis. the method includes: setting the mask parameter in advance for thefixed interference region in the video monitor scene in order to eliminate the interference of the fixed interference region for the rocket identification; collecting the video image about the videomonitoring scene; judging the video monitoring scene is in the daytime or the night according to the luminance value of the video image; if the video monitoring scene is in the daytime, conducting thedaytime rocket detecting and identifying process for the video image of the mask by utilizing the mask parameter to obtain the smoke and fire region related identification; if the video monitoring scene is in the night, conducting the at-night open flame detecting and identifying process for the video image of the mask by utilizing the mask parameter to obtain open flame region related identification. the forest rocket detecting and identifying method and apparatus provided by the invention can improve the forest rocket detecting and identifying sensitivity and accuracy.

Description

technical field [0001] The invention relates to multiple practical and innovative technologies such as image processing, image analysis, video pyrotechnic recognition process and processing means in forest pyrotechnic detection and recognition, and in particular to forest pyrotechnic detection and recognition technology based on video image intelligent analysis. Background technique [0002] Video smoke detection and recognition is the inevitable development trend of automation and intelligence of forest fire monitoring and alarm system. The existing various forest fire monitoring systems generally have problems such as high false alarm rate and false alarm rate, poor environmental adaptability, etc., and have not really solved the core problem of forest pyrotechnic intelligent identification technically and engineeringly. Therefore, how to use advanced image processing and analysis technology, starting from various problems encountered in the practice of forest fire prevent...
