Embodiment
Below in conjunction with accompanying drawing and preferred embodiments the present invention is described in further detail:
Please refer to Fig. 1, PTZ video camera adjusting device of the present invention is used to adjust a PTZ video camera 10, as changes camera lens visual angle of said PTZ video camera 10 etc.The preferred embodiments of said PTZ video camera adjusting device comprises a PTZ video camera control system 20, a video camera 30 and a display 40.
Said video camera 30 is used to take user 50 eyes, and the image of the eyes that obtain is sent to PTZ video camera control system 20.The image of 20 couples of users' 50 of said PTZ video camera control system eyes is analyzed, with the judgement action of user 50 eyes at this moment, and the camera lens of the said PTZ video camera 10 of corresponding in view of the above control, like the rotation of lens of control PTZ video camera 10.The image that said PTZ video camera 10 obtains shooting is sent to said display 40 to show.Said PTZ video camera control system 20 is communicated by letter with said video camera 30 and PTZ video camera 10 through wired or wireless network.In this execution mode; Said PTZ video camera 10 is installed on the ceiling in a room 60; 40 of said video camera 30 and displays are positioned at a said room of distance office far away, the image that said user 50 is positioned at said office and watches said display 40 to show.The situation that user 50 like this gets final product in the remote monitoring room 60.
Please consult Fig. 2 in the lump, said PTZ video camera control system 20 is used to detect the action of said user's 50 eyes, and according to the camera lens of the said PTZ video camera of the corresponding control of action of said user's 50 eyes.First preferred embodiments of said PTZ video camera control system 20 comprises that a memory module 200, contrasts a module 210 and a control module 220.
See also Fig. 3, store in advance the image of each action of the said user's 50 who takes eyes in the said memory module 200, as said user's 50 eyes normally open, eyeball turns left, eyeball is turned right, move on the eyeball and eyeball moves down etc.
When said PTZ video camera control system 20 is worked; The image of the said user's 50 that said video camera 30 will be taken eyes sends said contrast module 210 to, and the image of storing in the image that the said video camera 30 of said contrast module 210 contrasts is taken and the said memory module 200 is with the action of the eyes of judging said user 50.During the image that turns left like the eyeball that photographs said user 50 when said video camera 30; The image that said user 50 eyeballs that said video camera 30 will be taken turn left sends said contrast module 210 to; All images compare one by one in image that said contrast module 210 is taken said video camera 30 and the said memory module 200; When the image that turns left when image that said video camera 30 is taken and eyeball in the said memory module 200 was consistent, said contrast module 210 judged that promptly the action of said user's 50 eyes is the eyeball left-hand rotation.
Said control module 220 is according to the rotation of lens of the said PTZ video camera 10 of the corresponding control of the action of said user's 50 eyes.Such as, when said contrast module 210 judges that the action of said user's 50 eyes is the eyeball left-hand rotation, the lens left rotation of the said PTZ video camera 10 of said control module 220 corresponding controls.
See also Fig. 4, second preferred embodiments of said PTZ video camera control system 20 comprises an eyeball detecting module 230 and said control module 220.
The image of the said user's 50 that said video camera 30 will be taken eyes sends said eyeball detecting module 230 to, and 230 of said eyeball detecting modules utilize the eyeball detection techniques such as seamed edge search analytic approach of convention to judge the action of said user's 50 eyes.Said seamed edge is searched analytic approach the image of the user's 50 that takes eyes is carried out horizontal gradient and vertical gradient analysis to produce corresponding histogram, utilizes the histogram analysis method to detect the position of said user's 50 eyeball again.
Said control module 220 is according to the rotation of lens of the said PTZ video camera 10 of the corresponding control of the action of said user's 50 eyes.Such as, when said eyeball detecting module 230 judges that the action of said user's 50 eyes is the eyeball left-hand rotation, the lens left rotation of the said PTZ video camera 10 of said control module 220 corresponding controls.
To combine specific embodiment that the course of work of PTZ video camera adjusting device of the present invention is described below.
See also Fig. 5 A, be depicted as the panoramic view in said room 60.Said PTZ video camera 10 is used for said room 60 is taken.
See also Fig. 5 B, when the action of said user's 50 eyes when normally opening, said video camera 30 is taken and is obtained like the image among Fig. 5 B 600.The action of eyes that this moment, 20 of said PTZ video camera control system were judged said users 50 is for normally opening, and the camera lens of controlling said PTZ video camera 10 60 takes over against the room, obtains like the image among Fig. 5 B 601.
See also Fig. 5 C, when the action of said user's 50 eyes is an eyeball when turning left, said video camera 30 is taken and is obtained like the image among Fig. 5 C 602.Said PTZ video camera control system 20 judges that the action of said user's 50 eyes is that eyeball turns left, and controls the lens left rotation of said PTZ video camera 10, obtains like the image among Fig. 5 C 603.
See also Fig. 5 D, when the action of said user's 50 eyes is an eyeball when turning right, said video camera 30 is taken and is obtained like the image among Fig. 5 D 604.Said PTZ video camera control system 20 judges that the action of said user's 50 eyes is that eyeball is turned right, and the camera lens of controlling said PTZ video camera 10 obtains like the image among Fig. 5 D 605 to right rotation.
See also Fig. 5 E, when the action of said user's 50 eyes is when moving on the eyeball, said video camera 30 is taken and is obtained like the image among Fig. 5 E 606.Said PTZ video camera control system 20 judges that the action of said users' 50 eyes is to move on the eyeball, and the camera lens of controlling said PTZ video camera 10 rotates up, and obtains like the image among Fig. 5 E 607.
