All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in FIGS. 1 and 2, an embodiment of the present invention provides a target tracking anti-snoop system, which comprises: the system comprises an automatic tracking module 10, a ranging module 20, a laser generating module 30 and a main control module 40.

The camera unit 11 is further connected to the angle adjusting unit 12 in a transmission manner, and the angle adjusting unit 12 can drive the camera unit 11 to scan within a range of 360 degrees in space to find and track a corresponding target. The main control module 40 controls the camera unit 11 to scan the monitored area through the angle adjustment unit 12.
As shown in fig. 3, the angle adjusting unit 12 specifically includes: an azimuth rotation positioning mechanism 121 and a pitch rotation positioning mechanism 122.
The camera unit 11 is in transmission connection with the pitch rotation positioning mechanism 122, and is driven by the pitch rotation positioning mechanism 122 to perform pivotal swing in a vertical plane. The azimuth rotation positioning mechanism 121 is connected to the bottom of the pitch rotation positioning mechanism 122 in a transmission manner, and the entire camera unit 11 and the pitch rotation positioning mechanism 122 are driven by the azimuth rotation positioning mechanism 121 to pivot in the horizontal plane. Thus, the camera unit 11 can scan a space over 360 ° by driving the azimuth rotary positioning mechanism 121 and the elevation rotary positioning mechanism 122.
In order to achieve precise control of the camera unit 11, the azimuth rotation positioning mechanism 121 and the pitch rotation positioning mechanism 122 each employ a servo motor. The camera unit 11 is driven by two groups of servo motors, and performs pivoting swing within an angle range of 0-360 degrees on a vertical surface and performs pivoting swing within an angle range of 0-360 degrees on a horizontal surface under the measurement of a corresponding precise angle grating ruler.
At this time, the camera unit 11 is connected to an output terminal of one side of the pitch rotation servo motor, and accordingly, the grating reader 1221 and the circular grating 1222 are disposed at the other side of the pitch rotation servo motor. The camera unit 11 and the pitch rotation servo motor are connected to an output terminal of one side of the azimuth rotation servo motor, and accordingly, the grating read head 1211 and the circular grating 1212 are disposed on the other side of the azimuth rotation servo motor.
The precise angle grating ruler can measure the rotation angle of the servo motor, the measurement resolution can reach 0.1mrad, and the measurement precision can reach 0.025 mrad. Therefore, the precise angular displacement signal obtained by the precise angular grating ruler can control the rotation displacement of the servo motor, and the precise direction positioning is realized.
The main control module 40 sends a command signal to the ranging module 20 after the camera unit 11 finds a target. This master control module 40 can be the host computer, and this host computer has communication interface, and communication interface includes but not limited to following each item: RS485 interface, RS232 interface, CAN bus interface.
In order to realize the identification of the target image by the main control module 40, the main control module 40 controls the camera unit 11 to monitor the target by the following method:
because the target has the motion offset (x, y), the main control module 40 can identify the offset (a, b) of the target image in the image collected by the camera unit 11, and obtain the change value of the corresponding pixel point coordinate according to the actual offset (a, b) of the target image in the view field of the camera unit 11, so as to calculate the azimuth and the pitch rotation offset of the target, and the main control module 40 controls the camera unit 11 to track according to the azimuth and the pitch rotation offset of the target.
In addition, the target tracking and peeping system also comprises an alarm module; the main control unit controls the alarm module to alarm after the camera unit 11 finds the target.

Accordingly, the alarm module may be a speaker, an indicator light, or a communication module integrated in the main control module 40.
The distance measurement module 20 is configured to calculate a distance between the target and the target tracking and peeking system, and further set a corresponding focal length according to the distance, configure parameters of the interfering laser, and the like.
Specifically, the ranging module 20 includes: a laser ranging unit 21 and a processor 22. The processor 22 starts the laser ranging unit 21 to perform ranging according to the instruction signal, and feeds back the measured distance information to the main control module 40.

The laser ranging unit 21 includes: ranging light source 211, light source sampling mechanism 212, focusing mechanism 213, and detector 214.

Accordingly, a ranging laser emitter, an infrared laser emitter, or a green light emitter is integrated in the ranging light source 211. As shown in fig. 4, the three light beams pass through the multi-light-in-one optical path mechanism 215 and then are incident on the target. Thus, the multi-light-in-one optical path mechanism 215 focuses light beams with different wavelengths simultaneously, and the included angle between the light beams of different optical paths can be small, so that the focused light paths can be better directed to the same target.
Further, the optical path mechanism 215 includes a laser bias 2151 and a narrowband filter 2152, which are sequentially disposed. The bandwidth of the narrow-band filter 2152 is 1064 +/-1 nm, the cut-off area is larger than or equal to 6D, the wavelength is 532nm, and the laser reflectivity is larger than or equal to 99.5%.
After the ranging light emitted by the ranging light source 211 passes through the target, the ranging light is captured by the focusing mechanism 213 and the light source sampling mechanism 212 in sequence and then is sent to the detector 214, and the detector 214 can calculate the target distance according to the transmission time and the light speed of the light signal and feed back the distance information to the main control module 40.
Wherein, the range finding principle of detector 214 adopts pulsed laser range finding principle, promptly: first, a laser beam or a series of short pulse laser beams is emitted to the target, the laser beam reflected by the target is received by the photoelectric element, and the time from the emission to the reception of the laser beam is measured by the timer, thereby calculating the distance from the laser ranging unit 21 to the target.
The laser generation module 30 is configured to emit directional emission laser under the control of the main control module 40, so as to achieve interference, glare, blindness, and the like on a target, and further perform a peep protection on a monitored area.
Specifically, the laser generation module 30 includes: a laser 31 and a laser emission light path 32. The main control module 40 controls the laser 31 to emit laser light toward the target through the laser emission optical path 32 according to the distance information.
The laser 31 may be a medium power laser 31. The laser emission optical path 32 includes: a laser autofocus adjusting mirror 321, and a one-dimensional autofocus moving unit 322. At this time, the main control module 40 sets the focal length of the laser autofocus adjusting mirror 321 according to the distance information, and controls the moving distance of the one-dimensional autofocus moving unit 322, and the laser emitted by the laser 31 passes through the laser autofocus adjusting mirror 321 and then strikes on the target, thereby achieving interference, glare, blindness, and the like on the target.
In one embodiment, the one-dimensional auto-focus moving unit 322 may employ a stepping motor or a servo motor. At this time, the laser autofocus adjustment mirror 321 may be mounted on a lead screw driven by a stepping motor or a servo motor, and the position of the combined lens is rotationally moved by the motor, thereby focusing or defocusing the light.
In addition, the laser generating module 30 can also emit corresponding interference laser according to different target types. At this time, the main control module 40 further identifies the type of the target (animal, unmanned moving target (unmanned aerial vehicle, reconnaissance robot), and controls the laser 31 to emit laser toward the target according to the set light energy and light spot size according to the matching relationship between the type of the target and the light energy and light spot, so as to achieve a corresponding peeping-proof effect.
In one embodiment, the light source sampling mechanism 212 may employ a filter that reflects laser light to filter out background stray light; the focusing mechanism 213 may employ a combination of receive light focusing mirrors or a combination of lenses.
