Embodiment 1
[0028] An embodiment of the present invention provides a smoke detection method. figure 1 is a schematic flow chart of the smoke detection method of the embodiment of the present invention, such as figure 1 As shown, the smoke detection method includes:
[0029] Step 101, performing feature extraction on multiple frames of the image to be detected, and obtaining one or more candidate regions for detecting moving objects in the image to be detected;
[0030] Step 102, analyzing the area change, motion direction and shape change of the candidate region in the plurality of frames;
[0031] Step 103, judging whether there is smoke in the candidate area according to the analysis result.
[0032] In this embodiment, by extracting the slow moving object in the video, the trajectory of the moving object can be tracked through the candidate area, and the information such as the area change, moving direction and shape change of the candidate area where the moving object is located can...
Embodiment 2
[0088] An embodiment of the present invention provides a smoke detection device, which corresponds to the smoke detection method in Embodiment 1, and the same content will not be repeated here.
[0089] Figure 4 It is a schematic diagram of the composition of the smoke detection device of the embodiment of the present invention, such as Figure 4 As shown, the smoke detection device 400 includes: an acquisition unit 401, an analysis unit 402 and a judgment unit 403;
[0090] Among them, the acquisition unit 401 performs feature extraction on multiple frames of the image to be detected, and obtains one or more candidate regions for detecting moving objects in the image to be detected; the analysis unit 402 analyzes the candidate regions in the plurality of frames area change, motion direction and shape change; the judging unit 403 judges whether there is smoke in the candidate region according to the analysis result.

Embodiment 3
[0099] An embodiment of the present invention provides an electronic device, which includes the smoke detection device 400 described in Embodiment 2.
[0100] Figure 7 It is a schematic diagram of the structure of the electronic device of the embodiment of the present invention. like Figure 7 As shown, the electronic device 700 may include: a central processing unit (CPU) 100 and a memory 110 ; the memory 110 is coupled to the central processing unit 100 . Among them, the memory 110 can store various data; in addition, it also stores information processing programs, and executes the programs under the control of the central processing unit 100 .
[0101] In one embodiment, the functions of the smoke detection device 400 can be integrated into the central processing unit 100 . Wherein, the central processing unit 100 may be configured to implement the smoke detection method as described in Embodiment 1.
[0102] In another embodiment, the smoke detection device 400 can be...
