Embodiment Construction
[0040] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0041] The technology of the invention is based on the characteristics of the growth and change of the forest fire smoke, and detects the smoke rising from the forest fire point, so that the fire can be automatically found through the monitoring video at the early stage of the fire. The flow chart of fire smoke detection is as follows: figure 1 As shown in , assuming that smoke detection starts from the i-th frame of the video, the specific processing steps are:
[0042] Step 1: Start smoke detection from the i-th frame of the set frame number of the video, and the i-th frame video image I i Perform color-grayscale conversion to obtain grayscale image E i , and calculate the i-th frame video image I by frame-by-frame iteration method i background image for The specific iteration formula is:
[0043]
[0044] in, The i-1th frame video image I i-...
