There are reflection phenomena at the focal plane of the optical lenses used in the equipment, and they can return to the original path when they are irradiated by laser beams. The laser echo, that is, the "cat's eye effect" phenomenon of the optical lens.

In order to solve the problem that the function of the current photoelectric reconnaissance system is relatively single, it can only detect the target and cannot meet the needs of users in various aspects. This application provides a photoelectric reconnaissance system. Referring to FIG. 1 , it shows a schematic module diagram of an optoelectronic reconnaissance system provided by an embodiment of the present application, including an image processing and control module 1 , a ranging module 2 and a laser interference module 3 .

The image processing and control module 1 is used to identify the spot image, and judge whether the spot image is the spot image formed by the echo light signal reflected by the scout target; if so, send the first control signal to the ranging module 2; the ranging module 2, The communication is connected to the image processing and control module 1, and is used to receive the first control signal to start measuring the distance between the observation point and the reconnaissance target, and send the measured distance information to the image processing and control module 1; the image processing and The control module 1 is also used to receive distance information; based on the distance information, a second control signal is sent to the laser interference module 3; the laser interference module 3 is connected to the image processing and control module 1 for receiving the second control signal; based on The second control signal determines the interference distance of the interference laser, and launches the interference laser to the reconnaissance target.

In the above example, the electro-optical reconnaissance system uses the "cat's eye effect" of the scope to detect the sniper target. After the sniper rifle scope is irradiated by the detection laser emitted by the photoelectric reconnaissance system, the reticle of the scope reflects a strong echo light signal, and the echo intensity is 2-4 orders of magnitude higher than that of ordinary diffuse reflection echo. The image processing and control module 1 uses a spot recognition algorithm to perform feature recognition on the spot image, and judges whether the spot image is a spot image formed by the echo light signal reflected by the sniper rifle scope.

Among them, the "cat's eye" spot is displayed as a circular spot on the image, and the feature values of the spot image include the number of pixels occupied by the spot on the image, the brightness, the gradient of the spot, and the Gaussian coefficient.

When the image processing and control module 1 recognizes that the spot image is the spot image formed by the echo light signal reflected by the scope of the sniper target, it sends a control signal to the ranging module 2, so that the ranging module 2 starts to measure the observation point and the sniper. distance between targets.

When the image processing and control module 1 recognizes that the spot image is not the spot image formed by the echo light signal reflected by the scope of the sniper target, the image processing and control module 1 does not send a control signal to the ranging module 2 .

After receiving the control signal sent by the image processing and control module 1, the ranging module 2 starts to measure the distance between the observation point and the sniper target, and feeds back the distance information between the observation point and the sniper target to the image processing and control module. Module 1.

The diameter of the spot is determined by the size of the laser interference lens; when designing the laser interference lens, the size of the laser interference lens is determined according to the actual interference requirements. For example, the size of the laser interference lens is designed to be 50cm±5cm in diameter; the diameter of the spot formed by the interference laser is 50cm±5cm; the size of the laser interference lens is designed to be 60cm±5cm in diameter; The diameter of the spot is 60cm±5cm.

In a possible implementation, referring to Fig. 2, the photoelectric reconnaissance system also includes a display module 4; if the spot image is the spot image of the echo light signal reflected by the scouting target, the image processing and control module 1 is also used to display the spot image Send to the display module 4; the display module 4 is connected to the image processing and control module 1 through communication, and is used to receive the spot image, adjust the spot image to the center of the display interface, and display the spot image.

In the above-mentioned example, after the image processing and control module 1 recognizes that the spot image is the spot image formed by the echo light signal reflected by the scope mirror of the sniper target, the spot image is sent to the display module 4; Real-time display; and the display module 4 adjusts the spot image to the center of the cross-reticle of the display screen to help scouts aim at the sniper target.

In a possible implementation, referring to Fig. 2, the photoelectric reconnaissance system also includes a control button module 10; the control button module 10 is connected to the image processing and control module 1 through communication, and is used to receive the user's operation instruction and send the operation instruction Sent to the image processing and control module 1; the image processing and control module 1 is also used to receive the operation instruction sent by the control button module 10; based on the operation instruction, send the third control signal to the corresponding reconnaissance function module of the operation instruction, so that The reconnaissance function module completes the corresponding reconnaissance function; and sends the operation instruction to the display module 4, so that the display module 4 displays the operation instruction.

In the above example, the scouts can select the working mode of the photoelectric scouting system on the control buttons provided by the control button module 10. After the control button module 10 receives the mode selection information of the scouts, it sends the mode selection information to the image processing and control system. Module 1; image processing and control module 1 sends a control signal to the corresponding reconnaissance functional module according to the working mode of the photoelectric reconnaissance system, so that the corresponding functional module starts to work and completes the corresponding reconnaissance function. Among them, the reconnaissance function module includes a ranging module 2 , a laser interference module 3 , a laser emitting module 5 , an imaging receiving module 6 , an electronic compass 7 and a positioning module 8 .

In a possible implementation manner, referring to FIG. 2 , the photoelectric reconnaissance system further includes a laser emitting module 5 and an imaging receiving module 6 .

In the above example, the reconnaissance personnel select the automatic detection/interference mode on the control button of the photoelectric reconnaissance system; the photoelectric reconnaissance system responds to the mode selection request of the reconnaissance personnel, and turns on the laser emitting module 5; Scans with a detection laser beam to detect the presence of sniper targets in the target area. When there is a sniper target in the detection area, the scope of the sniper target reflects the detection laser beam to form an echo light signal. Among them, the wavelength of the detection laser beam is greater than 800 nanometers, which is invisible to the human eye, and has concealment during detection to ensure the safety of scouts.

The imaging receiving module 6 receives the echo light signal reflected by the scope of the sniper target, generates a spot image of the echo light signal, and sends the spot image of the echo light signal to the image processing and control module 1 . It should be noted that the spot image also includes an image of background light, and the spot recognition algorithm in the image processing and control module 1 only recognizes the spot image.

The imaging receiving module 6 adopts a low-illuminance imaging detector, so that the photoelectric reconnaissance system can detect the sniper target at night. The low-illuminance imaging detector can form a clear image in the daytime; it can still image at night when the illumination is 10 ^-3 Lux.

In a possible implementation manner, referring to FIG. 2 , the photoelectric reconnaissance system further includes an electronic compass 7 and a positioning module 8 .

It is used to detect the geographic location information of the observation point and send the geographic location information of the observation point to the image processing and control module 1; the image processing and control module 1 is also used to receive the azimuth angle information and the geographic location information of the observation point ; Based on the azimuth angle information, the geographic location information of the observation point and the distance information, determine the geographic location information of the reconnaissance target; send the geographic location information of the reconnaissance target to the display module 4; the display module 4 is also used to receive the image processing and control module 1 The geographic location information of the reconnaissance target is sent; based on the geographic location information of the reconnaissance target, the geographic location of the reconnaissance target is displayed.

In the above example, when the scouts turn on the photoelectric scouting system, the electronic compass 7 and the positioning module 8 start automatically; the electronic compass 7 feeds back the orientation information of the scouting area in real time to the image processing and control module 1 in real time; The control module 1 feeds back the geographic location information of the observation point in real time. Wherein, the positioning method adopted by the positioning module 8 may be Beidou positioning.

To the display module 4, the reconnaissance information of the photoelectric reconnaissance system is displayed in real time by the display module 4, so that the reconnaissance personnel can understand the current trends of themselves and the sniper target, and ensure the safety of the reconnaissance personnel.

In a possible implementation manner, referring to FIG. 2 , the photoelectric reconnaissance system further includes a power supply module 9 . The power supply module 9, as the power source of the photoelectric reconnaissance system, supplies power to the image processing and control module 1, the image processing and control module 1 is an imaging receiving module 6, a laser emitting module 5, a laser interference module 3, a distance measuring module 2, and an electronic compass 7 , the positioning module 8 and the display module 4 supply power.

In a possible implementation, the image processing and control module 1 is also used to obtain the visibility parameters and humidity parameters of the current environment; calculate the atmospheric transmittance of the current environment based on the visibility parameters; calculate the atmospheric transmittance of the current environment based on the humidity parameters beam energy transmittance; determine the laser power of the interfering laser based on the atmospheric transmittance and the beam energy transmittance; send the laser power of the interfering laser to the laser interference module 3 .

In the above example, the scout provides control keys to input the visibility parameters and humidity parameters of the current environment. The control button module 10 sends the parameters input by the scouts to the image processing and control module 1, and the image processing and control module 1 calculates the atmospheric transmittance and beam energy transmittance of the current environment.

The formula for calculating the atmospheric transmittance is:

T(R, λ)=exp(-σ _T R); σ _T ＝3.91/R _v (550/λ) ^q ;

Among them, R _v >50km, q=1.6; R _v ≈10km, q=1.3; R _v <6km, q=1.0; T is the atmospheric transmittance; R is the distance between the observation point and the interference target;

σ _T is the atmospheric extinction coefficient; R _v is the atmospheric visibility parameter; λ is the wavelength of the interfering laser.

The relationship between humidity and beam energy transmittance f(x)=μ x;

Among them, μ is the humidity coefficient, and x is the air humidity.

Among them, the energy transmittance and humidity are fitted through MATLAB to obtain the humidity coefficient μ.

Under the premise of considering the visibility and humidity of the current environment, the laser power of the interfering laser = laser power density * spot area / atmospheric transmittance / beam energy transmittance.

The power density of the interfering laser ρ=(P×T×f(x))/S;

Among them, P is the power of the interfering laser; S is the area of the spot formed by the interfering laser.

The area of the spot formed by the interfering laser is constant. In the case of the same interfering distance, if the beam energy transmittance is low, the power density of the interfering laser will decrease; in order to ensure the interference effect of the equipment, that is, the power density of the interfering laser remains unchanged. It is necessary to increase the emission power of the laser.

After the image processing and control module 1 calculates the laser power of the interference laser, it sends the value of the laser power to the laser interference module 3, and the laser interference module 3 emits an interference laser beam of corresponding power.

A photoelectric reconnaissance instrument, including one or more photoelectric reconnaissance systems in the above-mentioned embodiments.

The implementation principle of the photoelectric reconnaissance instrument is: scouts turn on the photoelectric reconnaissance instrument, input the current environmental visibility parameters and humidity parameters on the control buttons of the photoelectric reconnaissance instrument, and turn on the automatic detection/interference mode; in response to the reconnaissance personnel turning on the automatic detection/interference mode operation; the detection laser of the photoelectric reconnaissance instrument is turned on, and the scanning laser is emitted to the target area to detect the target area; the spot image formed by the echo light signal reflected in the target area is acquired and identified, and it is judged whether the spot in the spot image is "Cat's eye" light spot; when the light spot in the light spot image is a "cat's eye" light spot, display the image of the "cat's eye" light spot on the display interface, and adjust the light spot image to the center of the cross on the display interface to aim at the target area. Sniper target; at the same time, measure the distance between the observation point and the sniper target, and the ranging module 2, electronic compass 7 and Beidou positioning module run simultaneously to determine the geographic location information of the sniper target; laser interference module 3 according to the observation The distance information between the point and the sniper target is used to determine the interference distance of the interference laser; combined with the visibility parameters and humidity parameters of the current environment, the power of the interference laser is determined; the interference laser beam is launched to the sniper target to suppress, blind and dazzle Sniper target.

The current sniper detection system includes passive detection system and active detection system; passive detection system such as acoustic detection system and infrared detection system; active detection system such as laser detection system.

The acoustic detection system determines the position of the sniper target by receiving and measuring the muzzle shock wave of the sniper rifle and the shock wave generated by the flight of the projectile; , suddenly expands and mixes with the atmosphere, forming a muzzle shock wave (explosion sound) that propagates outward at the speed of sound; while a high-speed flying warhead will rub against in the air to produce eddy currents, shock waves and flight noise. The infrared detection system determines the location of the sniper target by detecting the muzzle flash and the infrared signal of the flying projectile; the infrared detector can detect the flash of the bullet ejected from the chamber; because the temperature of the flying projectile is higher than that of the surrounding air, the infrared detector can detect According to the infrared characteristics of the projectile, through the flight trajectory of the projectile, the position of the sniper target can be traced back. Both the acoustic detection system and the infrared detection system detect the sniper target after the sniper target has fired. The sniper target may have changed the combat position, and the time lag makes it difficult to deal with it in advance.

The laser detection system uses the "cat's eye" effect to actively irradiate the laser beam in the invisible light band to generate a strong reflected echo light signal on the reticle of the sniper target sight, thereby detecting the sniper target. However, when this system finds a sniper target, it cannot immediately dispose of the sniper. It needs to report the position of the sniper target to the scouts before disposing of it, which greatly delays the disposal time and increases the risk of combat.

The photoelectric reconnaissance instrument provided by this application immediately emits an interference laser to deal with the sniper target after finding the sniper target, so that the sniper target does not have time to respond, and ensures that the sniper target does not change position when the sniper target is interfered; Combining the distance measuring module 2, the electronic compass 7 and the Beidou positioning module, the geographic location of the sniper target is determined, and the location reconnaissance of the sniper target is more accurate.

The photoelectric reconnaissance instrument provides a variety of external interfaces, and establishes connections with various military equipment through the external interface, and cooperates with various military equipment. For example, photoelectric reconnaissance instruments can be installed on equipment such as reconnaissance vehicles or reconnaissance ships to help reconnaissance personnel discover and monitor the movement of targets.
