Abstract
The utility model discloses an automatic tracking device based on passive type infrared induction. The automatic tracking device comprises a camera, a left side infrared sensor, a right side infrared sensor, a comparison driving device and a servo motor, wherein the left side infrared sensor and the right side infrared sensor which are used for sensing human body infrared source intensity are arranged on the left side and the right side of the camera; the comparison driving device receives signals transmitted by the left side infrared sensor and the right side infrared sensor and compares the signals so as to judge that the infrared source deviates leftwards or rightwards; corresponding driving current is generated and transmitted to the servo motor; and the comparison driving device receives the driving current and drives the camera to rotate. The automatic tracking device of the utility model determines the direction of a target by utilizing directivity and sensing range which a passive type infrared sensor has (namely, the sensing sensitivity of infrared sensor is different in all directions), automatically judges that the infrared source deviates leftwards or rightwards, and automatically tracks the target.
Description
Technical field
The utility model belongs to the application of electronic technology field, specifically a kind of autotracker based on passive infrared induction that can make the security protection camera from the motion tracking human motion.
Background technology
In order to ensure safety, the security protection camera has obtained using widely, and is maintaining public order and important function has been brought into play in aspect such as social stability.Common camera can only monitor there is not automatic following function towards a fixing orientation, and people can avoid the monitoring range of camera wittingly.
Summary of the invention
In order to overcome the problem that existing camera exists, the purpose of this utility model provides a kind of autotracker based on passive infrared induction, the direction that this device utilizes directivity that passive infrared transducer has and induction range (induction sensitivity that is infrared ray sensor is different on all directions) to determine target, automatically judge that infrared source takes back or take over, realize to target from motion tracking.
The purpose of this utility model is achieved through the following technical solutions:
A kind of autotracker based on passive infrared induction, it is characterized in that: this device comprises camera, left side infrared ray sensor, right side infrared ray sensor, comparison drive unit and servomotor, is used for experiencing the left side infrared ray sensor of human body infrared source strength and the left and right sides that the right side infrared ray sensor is separately positioned on camera; Infrared ray sensor and right side infrared ray sensor were sent here on the left of relatively drive unit received signal and comparison signal size are judged the infrared source orientation, produce the corresponding driving electric current and send servomotor to; Servomotor receives drive current and drives camera and rotates.
In the utility model, relatively drive unit receives signal and the comparison signal size that left side infrared ray sensor and right side infrared ray sensor are sent here, judges that the infrared source orientation is to take back or take over, and drive camera left or right rotate.
The utility model is two installations that transducer is suitable, i.e. appropriate location and cooperate suitable baffle plate can be easy to judge automatically that infrared source takes back or take over.The utlity model has following advantage:
(1) replace manual operation to follow the tracks of from motion tracking, realize to target from motion tracking.
(2), improved the ratio of useful picture greatly compared with the camera of fixed-direction.
(3) good economic worth and application prospect are arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of autotracker based on passive infrared induction described in the utility model, see Fig. 1, this device comprises camera 2, left side infrared ray sensor 3, right side infrared ray sensor 4, compares drive unit 5 and servomotor 6, is used for experiencing the left side infrared ray sensor 3 of human body infrared source 1 intensity and the left and right sides that right side infrared ray sensor 4 is separately positioned on camera 2; Infrared ray sensor 3 and right side infrared ray sensor 4 were sent here on the left of relatively drive unit 5 received signal and comparison signal size are judged 1 orientation 4, human body infrared source, are to take back or take over, and produce the corresponding driving electric current and send servomotor 6 to; Servomotor 6 receives drive current and drives camera 2 and rotates to the direction of taking back or take over.
When infrared ray source (human body) not on the video camera center line time, as when taking back, then the infra-red intensity experienced of left side infrared ray sensor will be greater than the right, the comparison drive circuit will produce the corresponding driving electric current turns left servomotor drive camera, till the infra-red intensity that the transducer of the right and left is experienced equates, in like manner as infrared source (human body) when taking over, camera is then turned right, thereby makes camera reach purpose from the motion tracking human motion.
