Abstract

The invention discloses a monocular positioning method and system for forestry fire prevention. The method includes: obtaining the three-dimensional coordinates of monitoring equipment and terrain data of the monitoring area; The group optimization algorithm calculates the optimal segmentation threshold of the image, performs multi-threshold segmentation on the image through the optimal segmentation threshold, and extracts the problem area in the image; extracts the characteristic parameters of the problem area, performs flame identification, and judges whether a Fire: For the problematic area where the fire occurs, combine the three-dimensional coordinates of the monitoring equipment and the terrain data of the monitoring area to locate the fire source. The invention can accurately segment the problem area and its boundary, determine the alarm point, and solve the intersection point of the ray equation and the terrain equation by using the monocular positioning technology, thereby improving the accuracy of identification and the three-dimensional positioning accuracy of the actual fire source.

Description

technical field [0001] The invention relates to the technical field of monocular positioning, in particular to a forestry fire prevention monocular positioning method and system. Background technique [0002] With the continuous development of afforestation, the area of ​​forest land and the volume of forest trees are increasing year by year, and the work of forest fire prevention is the top priority. Forest fires have the characteristics of high accidental occurrence, strong fire danger, wide operation range, and difficult prevention and control. With the continuous progress of society and the continuous development of science and technology, the technological content of forest fire prevention is also continuously increasing. Forestry fire prevention based on image vision Detection and positioning technology provides convenience for forest fire prevention work. [0003] At present, binocular positioning is mostly used in various scenes through camera equipment positioning,...
