Forest smoke-fire monitoring and recognizing method suitable for distributed type parallel processing

Abstract

The invention discloses a forest smoke-fire monitoring and recognizing method suitable for distributed type parallel processing. The method comprises the following steps of: uniformly segmenting an image of each frame in video stream into video blocks with the width being W and the height being H, carrying out distributed-calculation distribution and recovery on all video blocks, fully utilizing all computing resources, supporting and processing monitoring and recognition of the characteristics of smoke and fire of large-scale video stream. The forest smoke-fire monitoring and recognizing method disclosed by the invention has the advantages that the large-scale video stream can be conveniently concentrated, and by extraction and grouping of frames, the computing resources can be submittedto a distributed computing platform for unified management and parallel recognition algorithm processing, so that the recognizing and processing capabilities are enhanced; for the detailed recognition process, the extracted image frames are segmented, the characteristic threshold can be flexibly set, and the recognition sensitivity is controlled, so that the efficiency and the accuracy of forest smoke-fire monitoring and recognition are improved.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a forest fire monitoring and early warning method based on digital image processing and pyrotechnic recognition. Background technique [0002] At present, in forest fire monitoring and early warning, various technical means have been adopted all over the world. In recent years, the forestry departments at the city and county levels in our country have mainly adopted the real-time video monitoring method in key fire danger areas. [0003] The invention patent represented by application number 02135403.0 provides a real-time video-based forest fire prevention monitoring system integration solution. Based on this scheme, the centralized monitoring of real-time video of forest fire prevention in a certain area can be constructed, which is a kind of progress technically. Real-time video monitoring can play a very good role in preventing forest fire monitoring. However,...

Problems solved by technology

In the actual use of the system, the forest fire monitoring area in a certain administrative division is usually composed of multiple monitoring points distributed in various terrains, and the summary is sent back through the network level by level, especially to the provincial forestry authority In the future, the number of video channels that need to be processed at the same time may be as many as several hundred, so that the information processing centers of management departments at all levels need to process a huge amount of real-time video stream data at the same time, and the computing power of the running recognition algorithm is also raised. requirements
