Embodiment
Below in conjunction with accompanying drawing and better embodiment, the present invention is described in further detail:
Please refer to Fig. 1 and Fig. 2, the better embodiment of fan 1 of the present invention comprises flabellum 10, shell 12,1 first actuator 15,1 second actuator 18 and a control system 19, wherein this flabellum 10, shell 12, first actuator 15 and the second actuator 18 are consistent with existing fan, this first actuator 15 is provided for flabellum 10 and rotates, this second actuator 18, for adjusting the wind direction of fan 1, namely makes fan " yaw ".
This control system 19 comprises an imaging means 190, humanoid memory module 191, humanoid detecting module 192 and a position puocessing module 195.This imaging means 190 is installed on shell 12, and swings together along with fan, for take always fan wind to the image of scene in dead ahead.This humanoid memory module 191, humanoid detecting module 192 and position puocessing module 195 can for the software modules performed by processor, wherein store some different manikins in this humanoid memory module 191, this some manikin can carry out shooting by imaging means 190 couples of crowds in advance and to go forward side by side row relax and obtaining.
This humanoid detecting module 192 for receiving the image from obtaining captured by imaging means 190, and is detected to judge whether have human body to occur in this image to it.In present embodiment, the image obtained can compare from the some different humanoid model be stored in humanoid memory module 191 by this humanoid detecting module 192, to judge whether there is human body in this image, if at least there is the part identical from some different humanoid models in this image, then think to there is human body in this image; If do not exist in this image and any one the identical part in some different humanoid models, then think to there is not human body in this image.Certainly, in other mode of execution, this humanoid detecting module 192 also can adopt other known algorithm to judge whether there is human body in image.
Judge human body now position when this position puocessing module 195 is for having human body in the picture, and send corresponding position signal according to the position information obtained.This second actuator 18 is connected with control system 19, for receiving the position signal from control system 19, and controls the second actuator 18 with the position of the wind direction to personnel place that adjust fan according to this position signal.
Working principle between second actuator 18 and control system 19 will be described with an example below:
This sentences fan suspension is example on the ceiling, and when opening fan, namely this control system 19 starts working, and this imaging means 190 starts the image before obtaining imaging means 190.As shown in Figure 3, this humanoid detecting module 192 pairs of images carry out detecting and judge now have human body to exist in this image, and are identified by humanoid region square frame.
This position puocessing module 195 pairs of images carry out computing to learn the center position of this human body, i.e. the center position of this square frame, and the central point of this square frame is designated first nodal point A.This position puocessing module 195 also carries out computing to the image of the scene obtained by imaging means 190, to obtain the center position of this image, and the center position of this image is designated the second central point B.
This position puocessing module 195 compares the position relationship between first nodal point A and the second central point B, and exports corresponding position signal, to control the second actuator 18, thus makes fan change its wind direction.Such as, as shown in Figure 3, this first nodal point A is positioned at the lower right of the second central point B, and the position signal that so this position puocessing module 195 output is corresponding moves toward lower right to make the second actuator 18.
Obviously, when fan changes its wind direction, this imaging means 190 is also along with its shooting direction of change.So at the second actuator 18 toward in the process of lower right movement, in this image captured by imaging means 190, the position of first nodal point A and the second central point B will be more and more close.
As shown in Figure 4, when first nodal point A in the image captured by imaging means 190 overlaps with the second central point B, this second actuator 18 stop motion, now, the wind direction of this fan is just to user.Afterwards, if when user moves in room, this control system 19 will repeat said process.
In addition, if there is some human bodies in the image captured by imaging means 190, this position puocessing module 195 can using the central point of some human bodies as first nodal point, and so after the second actuator 18 moves, the wind direction of this fan will towards the center of some people.
Please refer to Fig. 5, the better embodiment of control method for fan of the present invention comprises the following steps:
Step S1: the scene of this imaging means 190 to its front is taken, to obtain the image of scene.
Step S2: this humanoid detecting module 192 pairs of images are detected, to judge whether have human body to exist in image.If occur without human body in image, be then back to step S1.If there is human body to exist in image, then perform step S3.
Step S3: this position puocessing module 195 pairs of images carry out computing, to learn the position now residing for human body, and sends corresponding position signal.In present embodiment, this position puocessing module 195 judges that the position relationship between the central point of human body in image and the central point of image confirms the position now residing for human body.
Step S4: the position signal motion that this second actuator 18 sends according to position puocessing module 195, to change the wind direction of fan to the position residing for human body.
Said fans obtains the position information of user by its control system 19, and controls the motion of the second actuator 18 according to position information correspondence, thus the wind direction of fan can be made to continue towards user.
