The invention discloses a safety belt correct application intelligent video identification method. The safety belt correct application intelligent video identification method comprises collecting video images according to a front-end camera; uncompressing the collected video images and decomposing the video images into YUV (Luma and Chroma) pictures; converting the YUV pictures into RGB (Red Green Blue) pictures; decomposing the RGB pictures into pictures in frames and extracting a plurality of frames from the pictures at random for comparison and analysis; comparing the latter-frame picture with the former-frame picture and updating a background environment through auto tuning, disassociating a moving target object-particularly referring to people- from the back ground environment; performing gray level computation on upper body identification of a human body after the target object is targeted to accordingly determine whether a safety belt is correctly worn. The safety belt correct application intelligent video identification method can be used for conveniently and timely identifying whether a worker correctly wears a safety belt in electric power operation.
