Abstract
Description
Technical Field
[0001] This application relates to the field of reconnaissance technology, and more particularly to an optical-based reconnaissance system. Background Technology
[0002] Unmanned operations, search and strike capabilities, will become an important aspect of future warfare. Portable weapon stations, equipped with intelligent sights, can achieve rapid response within their field of vision and possess strong precision strike capabilities, making them a crucial component of future battlefield combat forces. Soldiers, acting as remote operators, are far from the front lines and confined to a limited field of vision. They cannot quickly, accurately, and efficiently acquire other threats over a wide area of the battlefield. Furthermore, the urban battlefield environment, with its obstructed views by buildings, presents significant challenges to target acquisition and locking by portable weapon stations. Even with high-performance ballistic computers or intelligent observation and aiming systems, they cannot fully adapt to the multi-dimensional, large-scale airspace combat scenarios. Simultaneously, enemy targets often utilize terrain or camouflage to launch surprise attacks, and current tactics lack effective countermeasures against such situations, posing a significant threat to our personnel. If rapid location and locking of enemy targets at greater distances and over larger areas can be achieved in high-intensity battlefield environments, it will greatly enhance our overall combat capabilities. In light of future warfare trends, the ability to help our soldiers and operators acquire enemy targets and their locations more quickly in complex battlefield environments under high-intensity combat conditions, thus enabling them to anticipate the enemy's moves in combat, is crucial for improving our combat personnel's precision strike capabilities and battlefield survivability. This technology has extremely wide applications and is in high demand. Summary of the Invention

Example
[0050] See Figure 4 As shown, this application embodiment provides an optical reconnaissance system, including: a housing, an optical detection component, and a driving mechanism. The optical detection component is disposed in the housing and includes multiple camera devices 2. Each camera device 2 is arranged sequentially at intervals along the circumference of the housing and is connected to the housing. Each camera device 2 includes a carrier 21 and a camera 22. The carrier 21 includes an upper side plate 211 and a lower side plate 212. The upper side plate 211 and the lower side plate 212 are movably connected and are both movably connected to the housing. A plurality of cameras 22 are respectively disposed on the upper side plate 211 and the lower side plate 212. The optical detection component is used to detect the optical position coordinates of a target object. The driving mechanism is disposed in the housing and is connected to the upper side plate 211 and lower side plate 212 of each of the camera devices 2 to drive the upper side plate 211 and lower side plate 212 to move relative to each other and adjust the total vertical field of view of the camera 22 on the upper side plate 211 and lower side plate 212.
[0051] In this embodiment, the angle between the upper side plate 211 and the lower side plate 212 can be adjusted via a driving mechanism, thereby adjusting the total vertical field of view of the camera 22 on the upper side plate 211 and the lower side plate 212 to meet different scenario requirements. When it is necessary to improve detection accuracy, the angle between the upper side plate 211 and the lower side plate 212 can be adjusted via the driving mechanism, for example, by reducing the total vertical field of view of the two, reducing the detection area, and improving detection accuracy. When it is necessary to detect a large area, the angle between the upper side plate 211 and the lower side plate 212 can be adjusted to increase the total vertical field of view of the two, increase the detection area, and reduce the positioning accuracy.
[0052] In some possible implementations, the housing includes a top plate 11 and a bottom plate 12, which are spaced apart. The upper side plate 211 is hinged to the top plate 11 at one end away from the lower side plate 212, and the lower side plate 212 is hinged to the bottom plate 12 at one end away from the upper side plate 211. A drive mechanism is connected to the top plate 11 and the bottom plate 12 to drive the top plate 11 and the bottom plate 12 to move closer to each other or further away from each other, so as to adjust the included angle between the upper side plate 211 and the lower side plate 212 of each camera device 2.
[0053] The angle between the upper side plate 211 and the lower side plate 212 can be precisely adjusted by controlling the distance between the top plate 11 and the bottom plate 12, that is, the total vertical field of view of the camera 22 on the upper side plate 211 and the lower side plate 212 can be adjusted.
[0054] In some possible implementations, the drive mechanism includes a drive rod 51. A threaded groove is provided on the top plate 11. The drive rod 51 rotatably passes through the bottom plate 12. The drive rod 51 has a threaded section that passes through the threaded groove and is threadedly connected to it. Rotation of the drive rod 51 drives the top plate 11 to move up and down, thereby adjusting the angle between the upper side plate 211 and the lower side plate 212 of each camera device 2. In this implementation, the up and down movement of the top plate 11 can be adjusted using the principle of the lead screw nut 1601. To precisely adjust the relative movement of the top plate 11 and the bottom plate 12, multiple guide cylinders can be vertically arranged on one of the top plate 11 and the bottom plate 12, and multiple guide shafts can be vertically arranged on the other. The guide shafts are inserted into the guide cylinders.
[0055] In some possible implementations, the bottom plate 12 is connected to a bottom shell 14 on the side facing away from the top plate 11, and a receiving cavity is formed between the bottom shell 14 and the bottom plate 12. The driving mechanism includes a driving assembly, which is at least partially disposed in the receiving cavity. The driving assembly is tractively connected to the driving rod 51 to drive the driving rod 51 to rotate forward / reverse.
[0056] Specifically, the drive assembly includes a first motor 52 and a gear train 53. The gear train 53 is disposed within the receiving cavity. The gears of the gear train 53 are arranged sequentially, and adjacent gears mesh with each other. One gear of the gear train 53 is connected to the drive rod 51, and the first motor 52 is connected to the gear at the other end of the gear train 53.
[0057] In some possible implementations, the optical-based reconnaissance system further includes an acoustic detection component 3 and a control component. The acoustic detection component 3 is disposed within the housing and is used to detect the acoustic position coordinates of the target. The control component is disposed within the housing and is electrically connected to both the optical detection component and the acoustic detection component 3, and is used to determine the final coordinates based on the optical and acoustic position coordinates.
[0058] Example 2
[0059] See Figures 1 to 9 As shown in the illustration, this application provides a more detailed description of an optical-based reconnaissance system, which includes: a housing, an optical detection component, an acoustic detection component 3, and a control component. The optical detection component is disposed within the housing and includes multiple camera devices 2 arranged sequentially along the circumference of the housing. The optical detection component is used to detect the optical position coordinates of a target. The acoustic detection component 3 is disposed within the housing and is used to detect the acoustic position coordinates of the target. The control component is disposed within the housing and is electrically connected to both the optical detection component and the acoustic detection component 3. The control component is used to determine the final coordinates of the target based on the optical and acoustic position coordinates.
[0060] In this embodiment, the reconnaissance system comprises multiple camera devices 2 and acoustic detection components 3 forming an acoustic-optical compound eye detection array. This array creates an effective field of view that radiates outward in a hemispherical shape, enabling the detection of targets across the entire range from the ground to the air. Furthermore, by combining multi-camera array image stitching technology with deep learning target detection, recognition, and localization technology, it can efficiently detect, identify, and locate typical target information in complex battlefield environments in real time. This allows for broader and longer-range acquisition of effective information in complex battlefield environments, as well as more accurate and faster detection, identification, and localization of typical targets. This includes efficient reconnaissance, identification, and localization of typical targets such as enemy aerial drones, snipers concealed on high ground and in building clusters, enemy ground defense targets, and camouflaged targets, providing information support for battlefield situational awareness and assessment.
[0061] To address the need for efficient and accurate identification of concealed, lurking, and camouflaged targets in intelligent battlefields, and building upon existing acoustic-optical composite detection capabilities, research is being conducted on the transformation and application of a large-area multi-target reconnaissance system based on acoustic-optical compound eyes. Key technologies to be overcome include lightweight design of the acoustic-optical reconnaissance payload structure, dynamic visual image stitching and autonomous target recognition, acquisition and processing of characteristic acoustic information from combat weapons, acoustic-optical information fusion, and adaptation of the acoustic-optical reconnaissance payload to unmanned combat platforms. This will solve the problems of difficulty in detecting and identifying concealed, lurking, and camouflaged targets during combat, and enhance our ability to accurately perceive and predict battlefield situations. The technology maturity level has reached 4.
[0062] See some possible implementations. Figure 2 and Figure 3 As shown, the camera device 2 includes a carrier 21 and a camera 22 mounted on the carrier 21, the carrier 21 being connected to the housing. The fields of view of adjacent cameras 22 on each camera device 2 overlap. The horizontal field of view acquired by each camera device 2 is not less than 180°.
[0063] In this embodiment, 20 cameras and 6 acoustic sensors 31 are stitched and integrated to form a visual image detection array and an acoustic detection array. The reconnaissance system divides the 180° horizontal field of view into 5 detection areas. Each detection area can be configured with four cameras and one acoustic sensor 31. The field of view overlap angle of two adjacent cameras is ≥36°, which can locate targets within the field of view based on the principle of binocular vision.
[0064] The optical detection component is an optical compound eye used for visual information acquisition and transmission. It consists of a control component or other control system for visual image stitching, visual information processing, visible target recognition, and positioning, aiming to fully obtain and effectively process the image information of the target being measured. The visual image stitching mainly studies the stitching of images output from multiple camera devices 2 to form a wide-angle image with a 180° field of view. This allows for the display, recognition, and positioning of the target being measured within a single image, while also facilitating user observation.
[0065] The optical detection and control components primarily identify and classify the target based on the established dataset. The main research focuses on locating the target within the field of view using image information and based on the principle of binocular vision.
[0066] See some possible implementations. Figure 2 and Figure 3As shown, the carrier component 21 includes an upper side plate 211 and a lower side plate 212. The upper side plate 211 and the lower side plate 212 are connected and have an included angle. A camera 22 is provided on both the upper side plate 211 and the lower side plate 212. The shooting fields of view of the camera 22 on the upper side plate 211 and the camera 22 on the lower side plate 212 overlap. The total vertical field of view angle of the camera 22 on the upper side plate 211 and the camera 22 on the lower side plate 212 is 45° to 110°.
[0067] Optionally, the housing includes a top plate 11 and a bottom plate 12, which are spaced apart. Each of the camera devices 2 is disposed between the top plate 11 and the bottom plate 12. An upper side plate 211 is connected to the top plate 11, and a lower side plate 212 is connected to the bottom plate 12. A cavity is formed between the top plate 11, the bottom plate 12, and each of the camera devices 2. The control assembly is disposed within the cavity. A heat dissipation slit a is formed between the carrier components 21 of adjacent camera devices 2, communicating with the cavity, to facilitate heat dissipation of the internal structure.
[0068] See some possible implementations. Figure 3 As shown, the reconnaissance system housing includes a rear sealing plate 13. The top plate 11, bottom plate 12, and each of the camera devices 2 enclose a communication opening that connects to the cavity. The rear sealing plate 13 is connected to the top plate 11 and bottom plate 12 to close the communication opening. A ventilation opening (not shown) is provided on the rear sealing plate 13. Convection is formed between the multiple heat dissipation slits a and the ventilation openings, improving heat dissipation efficiency. The heat dissipation slits a are arranged sequentially at intervals along the circumference of the housing, which facilitates uniform heat dissipation inside the cavity.
[0069] See some possible implementations. Figure 8 As shown, the reconnaissance system includes multiple elastic elements 4, each of which is connected to two adjacent carrier elements 21 to cover the heat dissipation gap a between them. The elastic elements 4 prevent large-volume impurities from entering the cavity through the heat dissipation gap a, thus preventing the accumulation of a large amount of impurities inside the cavity.
[0070] See some possible implementations. Figure 2 and Figure 3 As shown, the acoustic detection component 3 includes multiple acoustic sensors 31, each of which is disposed on the top plate 11. In this embodiment, the acoustic sensors 31 constitute an acoustic detection array, which can be used to collect sounds from different spatial directions. After the acoustic sensors 31 are arranged according to specified requirements, the location of the sound source can be obtained by adding a corresponding algorithm (arrangement + algorithm).
[0071] This application also provides a method for controlling a reconnaissance system, including:
[0072] The control component controls the optical detection component and the acoustic detection component 3 to start working respectively. The optical detection component detects the optical position coordinates of the target object, and the acoustic detection component 3 detects the acoustic position coordinates of the target object. It should be noted that the optical position coordinates are the coordinates of the target object detected by the optical detection component, and the acoustic position coordinates are the coordinates of the target object detected by the acoustic detection component 3.
[0073] The control components determine the calculation coefficients for the optical and acoustic position coordinates, respectively.
[0074] The control component determines the final coordinates of the target object based on the optical position coordinates, acoustic position coordinates, and the calculated coefficients of the optical and acoustic position coordinates.
[0075] For example, by multiplying the optical position coordinates by the corresponding coefficient, multiplying the acoustic position coordinates by the corresponding coefficient, and then fusing the two multiplied coordinates, the final coordinates of the target object can be obtained.
[0076] Specifically, the final X-axis coordinates of the target object can be obtained by multiplying the X-axis coordinate of the optical position by the corresponding coefficient and then adding the X-axis coordinate of the acoustic position by the corresponding coefficient. The final Y-axis and Z-axis coordinates of the target object can be obtained in the same way.
[0077] In some possible implementations, the control component receives control commands to determine the calculation coefficients for the optical and acoustic position coordinates. For example, the operator can manually set the coefficients based on weather conditions. When the weather is clear and visibility is high, the calculation coefficient for the optical position coordinates can be increased, and the calculation coefficient for the acoustic position coordinates can be decreased. When visibility is low (such as at night, in foggy weather, etc.), the calculation coefficient for the optical position coordinates can be decreased, and the calculation coefficient for the acoustic position coordinates can be increased. When the optical detection component does not detect the target, the calculation coefficient for the optical position coordinates can be set to zero.
[0078] The control components can also determine the calculation coefficients for optical and acoustic position coordinates based on the clarity of the detected target. For example, the reconnaissance system can detect the clarity of the captured target and set the calculation coefficients for the optical position coordinates accordingly. When visibility is low (such as at night, in foggy weather, etc.), the clarity of the captured target is low, and the calculation coefficients for the optical position coordinates can be adaptively reduced while the calculation coefficients for the acoustic position coordinates are increased. When the optical detection component does not detect the target, the calculation coefficients for the optical position coordinates can be set to 0, and the target's position is mainly determined by the acoustic detection component 3. In this case, the sum of the calculation coefficients for the optical and acoustic position coordinates is 1.
[0079] The working mode of the reconnaissance system e in this application is mainly for two types of situations. First, the optical detection component can quickly detect the target within a 180° field of view in front. In this case, the optical detection component is mainly used for detection. Second, it is for targets that are concealed (behind the inner wall of a building), dimly lit (at night or in environments with poor lighting), obscured (behind fortifications and bunkers), and camouflaged (camouflaged equipment). These types of targets are not easily detected by light, but can be detected and located by the acoustic signals generated during the firing of their weapons. In this case, the acoustic detection component 3 is mainly used for detection and location.
[0080] Example 3
[0081] See Figures 4 to 7 As shown in the illustration, this application embodiment further describes the detection system e in detail, which includes: a housing, an optical detection component, an acoustic detection component 3, and a driving mechanism. The optical detection component is disposed in the housing and includes multiple camera devices 2 arranged sequentially along the circumference of the housing. Each camera device 2 includes an upper side plate 211 and a lower side plate 212, which are movably connected. Both the upper and lower side plates 211 and 212 are movably connected to the housing. A plurality of cameras 22 are respectively disposed on the upper and lower side plates 211 and 212. The optical detection component is used to detect the optical position coordinates of a target object. The acoustic detection component 3 is disposed in the housing and includes multiple acoustic sensors 31. The acoustic detection component 3 is used to detect the acoustic position coordinates of a target object. A drive mechanism is disposed in the housing. The drive mechanism is in transmission cooperation with each of the optical detection components and the acoustic detection components 3 to drive and adjust the relative movement of the upper side plate 211 and the lower side plate 212, adjust the total vertical field of view angle of the camera 22 on the upper side plate 211 and the lower side plate 212, drive each acoustic sensor 31 of the acoustic detection components 3 to move, and adjust the position of each acoustic sensor 31.
[0082] In this embodiment, the angle between the upper side plate 211 and the lower side plate 212 can be adjusted via a driving mechanism, thereby adjusting the total vertical field of view of the camera 22 on the upper side plate 211 and the lower side plate 212 to meet different scenario requirements. When it is necessary to improve detection accuracy, the angle between the upper side plate 211 and the lower side plate 212 can be adjusted via the driving mechanism, for example, by reducing the total vertical field of view of the two, reducing the detection area, and improving detection accuracy. When it is necessary to detect a large area, the angle between the upper side plate 211 and the lower side plate 212 can be adjusted to increase the total vertical field of view of the two, increase the detection area, and reduce the positioning accuracy.
[0083] In this embodiment, the driving mechanism adjusts the position of each acoustic sensor 31 while simultaneously adjusting the total vertical field of view of the cameras 22 on the upper side plate 211 and lower side plate 212, thus adjusting the detection and positioning accuracy of the acoustic detection component 3. Preferably, the driving mechanism adjusts the optical detection component and the acoustic detection component 3 so that their detection accuracy changes synchronously. That is, adjusting the detection area of the optical detection component to be smaller improves its detection accuracy, while the driving mechanism drives each acoustic sensor 31 to increase the distance between them, thus improving the detection and positioning accuracy of each acoustic detection component 3. The driving mechanism enables the positioning accuracy of the optical detection component and the acoustic detection component 3 to change synchronously, improving positioning reliability.
[0084] In some possible implementations, the housing has a top plate 11 with multiple sliding guides 111 on it. At least some of the acoustic sensors 31 are slidably connected to the corresponding sliding guides 111. The drive mechanism has multiple movable push rods 54, each connected to a corresponding acoustic sensor 31. The drive mechanism adjusts the tilt angle of each movable push rod 54 to drive each acoustic sensor 31 to slide along the corresponding sliding guide 111, thereby adjusting the position of the corresponding acoustic sensor 31. The greater the spacing between the acoustic sensors 31, the higher the detection and positioning accuracy.
[0085] The driving mechanism includes a fixed base 55 disposed within the cavity of the housing. The fixed base 55 is in a constant position and is fixed relative to the base plate 12. Movable push rods 54 are sequentially spaced along the circumference of the fixed base 55. One end of each movable push rod 54 is hinged to the fixed base 55, and the other end is movably connected to a corresponding acoustic sensor 31. The driving mechanism is connected to the top plate 11 to drive the top plate 11 closer to or further away from the fixed base 55, thereby adjusting the tilt angle of the movable push rod 54 and causing it to push against and slide the acoustic sensor 31.
[0086] Each of the sliding guide parts 111 extends radially outwards from the position where the fixed seat 55 is projected onto the top plate 11 as the center. When each acoustic sensor 31 moves away from the center, the spacing between each acoustic sensor 31 increases, and the positioning accuracy of the acoustic detection component 3 (which can be a microphone array) is improved.
[0087] The sliding guide 111 may include a slit groove disposed on the top plate 11, and the acoustic sensor 31 is disposed through the slit groove. A hinge seat is disposed on one side of the acoustic sensor 31 inside the housing. The movable push rod 54 is hinged to the hinge seat. It should be noted that each acoustic sensor 31 can slide along the slit groove, but will not disengage from the slit groove.
[0088] In some possible implementations, the driving mechanism includes a driving rod 51. A threaded groove is provided on the top plate 11. The driving rod 51 is rotatably connected to the housing (e.g., connected to the bottom plate 12), and the driving rod 51 has a threaded section that passes through the threaded groove and is threadedly connected to it. Rotation of the driving rod 51 drives the top plate 11 to move up and down, adjusting the top plate 11 closer to or further from the fixed seat 55. In this implementation, the principle of a lead screw and nut is used to drive the up and down movement of the top plate 11. The housing may also include a bottom plate 12, which is fixed in position. The up and down movement of the top plate 11 relative to the bottom plate 12 can be adjusted using the principle of a lead screw and nut. To precisely adjust the relative movement of the top plate 11 and the bottom plate 12, multiple guide cylinders can be vertically arranged on one of the top plate 11 and the bottom plate 12, and multiple guide shafts can be vertically arranged on the other, with the guide shafts inserted into the guide cylinders.
[0089] See some possible implementations. Figure 5 As shown, the fixed seat 55 is annular and rotatably fitted onto the drive rod 51. Limiting portions (not shown) are provided at both ends of the drive rod 51 near the fixed seat 55 to restrict the fixed seat 55 from sliding along the drive rod 51. Under the limiting action of the two limiting portions, the height of the fixed seat 55 remains unchanged. An annular groove can be provided on the fixed rod, and the fixed seat 55 can be connected to the annular groove; the sidewalls on both sides of the annular groove serve as the limiting portions. The fixed seat 55 can be constructed from two detachably connected semi-annular bodies for easy connection to the drive rod 51. Under the limiting action of each movable push rod 54, the fixed seat 55 will not rotate around the drive rod 51. A bearing can be provided between the fixed seat 55 and the drive rod 51.
[0090] In some possible implementations, the housing has a base plate 12, the upper side plate 211 is hinged to the top plate 11 at one end away from the lower side plate 212, the lower side plate 212 is hinged to the base plate 12 at one end away from the upper side plate 211, and the drive rod 51 drives the top plate 11 and the base plate 12 to move closer to each other or further away from each other to adjust the included angle between the upper side plate 211 and the lower side plate 212 of each camera device 2.
[0091] The bottom plate 12 is connected to a bottom shell 14 on the side opposite to the top plate 11, and a receiving cavity is formed between the bottom shell 14 and the bottom plate 12.

[0093] Example 4
[0094] See Figure 1 , Figure 2 and Figure 9 As shown, this application provides a further detailed description of the reconnaissance system. The weapon system includes: a carrier device 6, a reconnaissance system, a portable weapon tactical device 7, and an integrated control terminal 8. The reconnaissance system e includes a housing, an optical detection component, an acoustic detection component 3, and a control component. The housing is disposed on the carrier device 6. The optical detection component is disposed on the housing and includes multiple camera devices 2 arranged sequentially along the circumference of the housing. The optical detection component is used to detect the optical position coordinates of a target. The acoustic detection component 3 is disposed on the housing and is used to detect the acoustic position coordinates of the target. The control component is disposed on the housing and is electrically connected to both the optical detection component and the acoustic detection component 3, used to determine the final coordinates of the target based on the optical and acoustic position coordinates. The portable weapon tactical device 7 is communicatively connected to the reconnaissance system e. The integrated control terminal 8 is communicatively connected to both the reconnaissance system e and the portable weapon tactical device 7.
[0095] When the portable weapon system 7 is remotely controlled, an intelligent integrated control terminal 8 can be selected. During information transmission, the portable weapon system 7 uses a network radio to send relevant information to the integrated control terminal 8 in real time. Based on this, the information transmission between the reconnaissance system e and the portable weapon system 7 can adopt a network cable transmission mode. An external router can be added to connect the reconnaissance system e, the portable weapon system 7, and the data transmission radio. The reconnaissance system e sends information to the portable weapon system 7, which is then identified by the processing system and sent to the integrated control terminal 8 in real time, informing the operator of the battlefield situation.
[0096] After the portable weapon system 7 is deployed, the reconnaissance system e is deployed nearby and adjusted for operation before commencing work. The reconnaissance system e of this application operates primarily in two modes: first, when the optical detection component can quickly detect targets within a 180° frontal field of view, detection is mainly performed using the optical detection component; second, when targeting concealed (behind building walls), dimly lit (at night or in environments with poor lighting), obscured (behind fortifications), or camouflaged (camouflaged equipment) targets, which are optically difficult to detect but can be detected and located using the acoustic signals generated during weapon firing, detection and location are primarily performed using the acoustic detection component 3.
[0097] The portable weapon system 7 can include a 5.8mm caliber machine gun. During use, the portable weapon system 7 is first deployed and fixed at a location on the battlefield for situational observation. The operator observes from the rear via an integrated control terminal 8 display device. Once a target is detected, the operator can confirm the target information on the integrated control terminal 8. After confirmation, a remote firing command is sent to complete the firing operation.
[0098] The support device 6 can be a tripod or a trolley for easy movement. For example, the support device 6 has a walking mechanism. The reconnaissance system is detachably connected to the vehicle body.
[0099] See Figure 6 and Figure 7 As shown, the reconnaissance system e may include a mounting plate 15, the housing is connected to the mounting plate 15, a locking mechanism is provided on the mounting plate 15, and a locking engagement part 61 is provided on the supporting device 6. When the reconnaissance system and the supporting device 6 are connected, the mounting plate 15 is fitted against the supporting device 6, and the locking mechanism and the locking engagement part 61 are locked together.
[0100] The locking engagement part 61 has multiple locking engagement sleeves, each of which is disposed on the supporting device 6. The locking mechanism includes a first gear 161, a second gear 162, a first directional rack 163, and a second directional rack 164. Both the first and second directional racks are slidably connected to the mounting plate 15, and are perpendicular to each other. Both the first gear 161 and the second gear 162 are rotatably disposed on the mounting plate 15. The first gear 161 meshes with the first directional rack, and the second gear 162 meshes with the second directional rack. Rotation of the first gear 161 causes the first directional rack 163 to engage with the corresponding locking engagement sleeve. Rotation of the second gear 162 causes the second directional rack 164 to engage with the corresponding locking engagement sleeve.
[0101] Optionally, the mounting plate 15 has a first protrusion and a second protrusion. A first connecting seat is provided at the end of the first protrusion, and a second connecting seat is provided at the end of the second protrusion. The first and second connecting seats are at different distances from the mounting plate 15. The first directional rack 163 is slidably connected to the first connecting seat, and the second directional rack 164 is slidably connected to the second connecting seat. The first and second directional racks are vertically offset and do not interfere with each other.
[0102] The first gear 161 and the second gear 162 are arranged sequentially along the thickness direction of the mounting plate 15, and the rotation axes of the first gear 161 and the second gear 162 are collinear and perpendicular to the mounting plate 15.
[0103] The reconnaissance system e includes two first-direction racks 163 and two second-direction racks 164. The two first-direction racks 163 are parallel and spaced apart. The two second-direction racks 164 are parallel and spaced apart. A first gear 161 is located between the two first-direction racks 163 and meshes with each of the two first-direction racks 163. A second gear 162 is located between the two second-direction racks 164 and meshes with each of the two second-direction racks 164.
[0104] Optionally, see Figure 4 , Figure 6 and Figure 7 As shown, the housing is provided with a guide sleeve b and a lead screw nut 1610. A guide post c is provided on the mounting plate 15, and a lead screw 167 is rotatably mounted on the mounting plate 15. The guide sleeve b is fitted onto the guide post c, and the lead screw 167 is threadedly connected to the lead screw nut 1610. Rotation of the lead screw 167 drives the housing to move up and down.
[0105] See Figure 6 and Figure 7 As shown, the reconnaissance system e includes a second motor 165, which is mounted on the mounting plate 15. The output shaft of the second motor 165 is connected to a third gear 166. A fourth gear 168 is mounted on the lead screw 167, and the rotation axes of the third gear 166 and the fourth gear 168 are perpendicular to each other. A drive rack 169 is slidably connected to the mounting plate 15. The drive rack 169 meshes with both the third gear 166 and the fourth gear 168.
[0106] The first gear 161, the second gear 162, and the fourth gear 168 are connected and rotate synchronously. It should be noted that when the reconnaissance system needs to be quickly assembled onto the carrier device 6, the second motor 165 can be controlled to rotate, driving the first gear 161, the second gear 162, and the fourth gear 168 to rotate, adjusting the retraction of the first directional rack 163 and the second directional rack 164. Then, the second motor 165 can be controlled to rotate in the opposite direction, causing the first directional rack 163 and the second directional rack 164 to extend and insert into their respective locking sleeves. Afterward, the second motor 165 can be controlled to rotate in either the forward or reverse direction. Provided that the first directional rack 163 and the second directional rack 164 do not disengage from the locking sleeves, the fourth gear 168 can be driven to rotate the lead screw 167, thereby fine-tuning the height of the housing. Operators can make adaptive adjustments according to actual needs.
[0107] In this embodiment, the reconnaissance system comprises multiple camera devices 2 and acoustic detection components 3 forming an acoustic-optical compound eye detection array. This array creates an effective field of view that radiates outward in a hemispherical shape, enabling the detection of targets across the entire range from the ground to the air. Furthermore, by combining multi-camera array image stitching technology with deep learning target detection, recognition, and localization technology, it can efficiently detect, identify, and locate typical target information in complex battlefield environments in real time. This allows for broader and longer-range acquisition of effective information in complex battlefield environments, as well as more accurate and faster detection, identification, and localization of typical targets. This includes efficient reconnaissance, identification, and localization of typical targets such as enemy aerial drones, snipers concealed on high ground and in building clusters, enemy ground defense targets, and camouflaged targets, providing information support for battlefield situational awareness and assessment.
[0108] To address the need for efficient and accurate identification of concealed, lurking, and camouflaged targets in intelligent battlefields, and building upon existing acoustic-optical composite detection capabilities, research is being conducted on the transformation and application of a large-area multi-target reconnaissance system based on acoustic-optical compound eyes. Key technologies to be overcome include lightweight design of the acoustic-optical reconnaissance payload structure, dynamic visual image stitching and autonomous target recognition, acquisition and processing of characteristic acoustic information from combat weapons, acoustic-optical information fusion, and adaptation of the acoustic-optical reconnaissance payload to unmanned combat platforms. This will solve the problems of difficulty in detecting and identifying concealed, lurking, and camouflaged targets during combat, and enhance our ability to accurately perceive and predict battlefield situations. The technology maturity level has reached 4.
[0109] Optionally, a cavity is formed between the top plate 11, the bottom plate 12, and each of the camera devices 2, and the control component is disposed within the cavity. A gap is formed between the carrier components 21 of adjacent camera devices 2, connecting the cavity. The gap facilitates heat dissipation of the internal structure.
[0110] In some possible implementations, the optical-based reconnaissance system includes an elastic element that connects two adjacent carrier elements 21 respectively, the elastic element covers the gap, or the elastic element divides the gap to form multiple holes.
[0111] The elastic element prevents large impurities from entering the cavity through the heat dissipation seam a, thus preventing the accumulation of a large amount of impurities inside the cavity. During the relative movement of the upper and lower plates, the shape of the heat dissipation seam a changes, and the elastic element can adapt to the deformation, thus maintaining coverage of the heat dissipation seam a.
[0112] In some possible implementations, the reconnaissance system may include a pressure strip detachably connected to the carrier member 21. The elastic member 4 includes multiple elastic strips arranged sequentially along the gap. One end of each elastic strip presses against a carrier member 21 and a corresponding pressure strip, while the other end presses against an adjacent carrier member 21 and a corresponding pressure strip. The pressure strip arrangement allows for the simultaneous pressing and fixing of multiple elastic strips, facilitating the connection and fixation of each elastic strip.
[0113] In some possible implementations, the gap formed between two adjacent carrier members 21 gradually decreases in width from the center towards the top plate 11 and the bottom plate 12, respectively, and the gap is approximately prismatic in shape. The natural length of each elastic strip also gradually decreases from the center of the gap towards the top plate 11 and the bottom plate 12, respectively. As the gap gradually changes, the elastic strips adapt accordingly, preventing uneven tension among them.
