Abstract
Description
Technical Field
[0001] This utility model relates to the field of tracking and control technology, specifically to a flight target assisted acquisition and tracking device. Background Technology
[0002] Traditional optical measurement equipment, such as precision measuring instruments, is mainly used for optical imaging detection of space targets such as UAVs, weather balloons, and geostationary satellites, while also being capable of tracking and measuring high-speed moving low-altitude targets.
[0003] However, optical measurement equipment has a long observation distance and often a small imaging field of view, making the initial target acquisition and tracking phase quite difficult. Therefore, the initial acquisition and tracking of low-altitude, visually visible targets often requires personnel at the front end to assist in alignment according to the actual situation. After the target is searched and brought into the optical lens's field of view, the operator then completes the target tracking and measurement through servo control. In other words, when tracking a close-range, high-speed moving target, auxiliary personnel are needed to assist in the operation to complete the tracking and alignment. Utility Model Content

[0036] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0040] Traditional optical measurement equipment, such as precision measuring instruments, is mainly used for optical imaging detection of space targets such as UAVs, weather balloons, and geostationary satellites, while also being capable of tracking and measuring high-speed moving low-altitude targets.
[0041] However, optical measurement equipment has a long observation distance and often a small imaging field of view, making the initial target acquisition and tracking phase quite difficult. Therefore, the initial acquisition and tracking of low-altitude, visually visible targets often requires personnel at the front end to assist in alignment according to the actual situation. After the target is searched and brought into the field of view of the optical lens, the operator completes the target tracking and measurement through servo control. That is, when tracking a close-range, high-speed moving target, auxiliary personnel are required to assist in the tracking and alignment. When auxiliary personnel assist in the operation, there are several drawbacks: First, it requires high skill in aiming. Since optical measurement equipment is no longer equipped with the old-fashioned aiming crosshairs, different personnel will have different aiming positions, and the auxiliary personnel cannot observe whether their aiming position is correctly imaged on the measurement lens image plane; second, low-altitude targets fly at high speeds, and once the aiming process exceeds the range of visual visibility, target acquisition and tracking cannot be completed; third, due to the excessive rotation speed of the equipment, when a target appears in the field of view of the optical measurement equipment, the operator can easily cause injury to the auxiliary personnel when controlling the rotation of the optical equipment through the servo system.
[0042] In response, this embodiment provides a flight target assisted acquisition and tracking device, such as... Figure 1 As shown, the flight target assisted acquisition and tracking device includes:
[0043] An auxiliary lens 10 is fixedly connected to the main lens. The auxiliary lens 10 is used to acquire auxiliary video signals from the acquisition position of the main lens, wherein the field of view of the auxiliary lens is larger than that of the main lens.
[0044] Specifically, the main lens is the imaging lens of an optical measuring device, which can be a precision measuring instrument. The main lens needs to rotate 360° to capture the measurement target. The acquisition orientation of the main lens is determined by its rotational spatial position; that is, the auxiliary lens 10 moves with the main lens. The field of view of the auxiliary lens 10 is larger than that of the main lens, meaning the field of view acquired by the main lens is included within the auxiliary lens 10. Optionally, the auxiliary lens 10 can be a wide-field-of-view lens.
[0045] Transmission module 20, which is connected to the auxiliary lens 10, is used to receive the auxiliary video signal and convert the auxiliary video signal into an auxiliary light signal before outputting it;
[0046] Specifically, the transmission module 20 first converts the auxiliary video signal into an optical signal, and then transmits the optical signal to the display module 30. Of course, the transmission module 20 can also receive control signals and transmit them to the auxiliary lens. The transmission module 20 includes at least a light emitting device and a light receiving device. Optionally, the transmission module 20 can be a conversion device between video signals and optical signals, and an optical transmission device.
[0047] The display module 30 is connected to the transmission module 20 and is used to receive the auxiliary light signal, restore the auxiliary light signal to a video signal, and output it for display, so as to enable target tracking based on the displayed video signal.
[0048] Specifically, after receiving the optical signal, the display module 30 first restores the optical signal to an auxiliary video signal, and then outputs the restored auxiliary video signal for display. Optionally, the display module 30 can be a conversion device between optical signals and video signals and a display device.
[0049] The flight target acquisition and tracking device provided by this utility model fixes an auxiliary lens to the main lens and moves synchronously with the main lens of the optical measurement equipment. It collects auxiliary video signals with a wider field of view than the main lens and transmits them to the display module for display. Thus, the operator of the main lens at the back end can detect and track the target based on the wide-field-of-view auxiliary video signal, eliminating the need for an auxiliary operator at the front end. Simultaneously, the wide-field-of-view auxiliary lens can capture areas beyond the naked eye's field of view, thereby improving tracking performance.
[0050] In some alternative implementations, such as Figure 2 As shown, the device includes:
[0051] A power supply module 40 is connected to the auxiliary lens 10 and is used to supply power to the auxiliary lens 10.
[0052] Specifically, the power supply module 40 supplies power to the auxiliary lens 10, enabling the auxiliary lens 10 to operate normally. Optionally, the power supply module 40 can be an external battery, or it can be a power supply device that supplies power to the main lens.
[0053] In some alternative implementations, such as Figure 3 As shown, the power supply module is the power supply device for the main lens. The power supply device for the main lens is connected to the auxiliary lens 10 and is used to transmit the power supply voltage of the main lens to the auxiliary lens to power the auxiliary lens 10.
[0054] refer to Figure 4The power supply device for the main lens specifically includes a main unit AC power supply, a conductive ring, and a DC power module. The main unit AC power supply transmits 220V AC power to the DC power module via the conductive ring. The DC power module converts the 220V AC power to 24V DC power before transmitting it to the main lens. The main power module is located in the onboard power distribution box. In this embodiment, the power supply terminal of the main lens is connected to the auxiliary lens 10 via a wire, or the power supply device for the main lens is connected to the auxiliary lens 10. The onboard power distribution box is located above the main lens, allowing direct access from the main lens's power supply cable to the auxiliary lens 10. The main lens's power supply device simultaneously powers both the auxiliary lens 10 and the main lens, thus requiring only one wire to power the auxiliary lens 10, significantly reducing power supply costs.
[0055] In some alternative implementations, such as Figure 5 As shown, the transmission module 20 includes:
[0056] The first analog video conversion unit 21 is connected to the auxiliary lens 10 and is used to convert the analog video signal into an auxiliary light signal and then output it.
[0057] Specifically, the first analog video conversion unit 21 is used to convert the analog video signal captured by the auxiliary lens 10 into an auxiliary light signal. Optionally, the first analog video conversion unit 21 can be any device that converts analog signals into light signals, and there is no limitation here.
[0058] The optical transmission unit 22 is connected to the first analog video conversion unit 21 and the display module 30 respectively, and is used to transmit auxiliary optical signals to the display module 30.
[0059] Specifically, the optical transmission unit 22 receives the auxiliary optical signal sent by the first analog video conversion unit 21, and transmits the auxiliary optical signal to the display module 30 via an optical line. Optionally, the optical transmission unit 22 includes an optical transmitter, an optical line, and an optical receiver.
[0060] In some alternative implementations, such as Figure 4 and Figure 6 As shown, the light transmission unit 22 is the light transmission device for the main lens, and the light transmission device includes:
[0061] The first optical fiber module is connected to the first analog video conversion unit and is used to receive and transmit the auxiliary optical signal;
[0062] An optical fiber slip ring, connected to the first optical fiber module, is used for rotating and transmitting the auxiliary optical signal;
[0063] The second optical fiber module is connected to both the optical fiber slip ring and the display module, and is used to receive the transmitted auxiliary optical signal and send it to the display module.
[0064] Specifically, the optical transmission unit 22 adopts the optical transmission device of the main lens. The optical transmission device of the main lens is used to transmit the main video transmission route of the main lens, that is, it transmits the main optical signal of the main video captured by the main lens through the first optical fiber module, and transmits it to the second optical fiber module through the optical fiber slip ring. The second optical fiber module is used to receive the main optical signal of the main video. It is worth noting that the second optical fiber module can be an optical fiber communication chassis.
[0065] In this embodiment, reference Figure 4 The main lens's optical transmission device is also used to transmit auxiliary optical signals from the auxiliary lens 10. The first fiber optic module includes at least an optical transmitting unit, and the second fiber optic module includes at least an optical receiving unit. The first fiber optic module transmits the auxiliary optical signal, which is then transmitted to the second fiber optic module via a fiber optic slip ring. The second fiber optic module receives the auxiliary optical signal. The first fiber optic module can be installed in the onboard power distribution box, and the auxiliary lens 10 can directly connect to the first fiber optic module via a signal cable. Thus, the auxiliary optical signal is transmitted to the display module 30 through the existing main lens's optical transmission device, eliminating the need for a separate optical transmission device and significantly reducing the transmission path cost of the video captured by the auxiliary lens.
[0066] In some alternative implementations, such as Figure 4 As shown, the second fiber optic module is connected to the main control module of the main lens. The main control module is used to output auxiliary control signals. The second fiber optic module receives the auxiliary control signals and transmits them to the auxiliary lens through the fiber optic slip ring and the first fiber optic module. The auxiliary control signals include focal length signals and aperture signals.
[0067] Specifically, the main control module is a computer that controls the main lens. The main control module is connected to the second fiber optic module. The main control module sends main control signals to the main lens through the second fiber optic module, fiber optic slip ring, and first fiber optic module. The main control signals include tracking orientation and focal length of the main lens.
[0068] In this embodiment, reference Figure 4 The main control module can be a master industrial computer. The main control module also receives auxiliary control commands from the auxiliary lens 10, sends the auxiliary control signals of the auxiliary control commands to the second fiber optic module, and transmits them to the auxiliary lens 10 via a fiber optic slip ring and the first fiber optic module, thereby controlling the focal length and aperture of the auxiliary lens 10. Thus, by controlling the aperture and focal length of the auxiliary lens 10 through the original control path, the control cost of the auxiliary lens 10 is greatly reduced.
[0069] In some alternative implementations, such as Figure 7 As shown, the display module 30 includes:
[0070] The second analog video conversion unit 31 is connected to the transmission module 20 and is used to convert the received auxiliary optical signal back into an auxiliary video signal and then output it.
[0071] Specifically, the second analog video conversion unit 31 is used to restore the auxiliary optical signal to the auxiliary video signal. Optionally, the second analog video conversion unit 31 can be any device for converting optical signals into analog signals, and there is no limitation here.
[0072] Display 32, which is connected to the second analog video conversion unit 31, is used to receive and display the restored auxiliary video signal.
[0073] Specifically, the display 32 is used to display the auxiliary video signal collected by the auxiliary lens 10. The operator detects the target based on the large field-of-view auxiliary video signal and controls the main lens to track the target. At the same time, the operator can observe whether there are clouds obstructing the flight path of the tracked target, allowing the operator to anticipate and switch the tracking state in advance to ensure the tracking effect.
[0074] In some alternative embodiments, the main view axis of the auxiliary lens 10 overlaps with the main view axis of the main lens.
[0075] Specifically, the main viewing axis of the auxiliary lens 10 overlaps with that of the main lens, ensuring that the main viewing axis of the auxiliary lens 10 is consistent with that of the main lens. This guarantees that the image captured by the main lens is included within the image captured by the auxiliary lens 10, thus enabling the azimuth angle of the auxiliary lens to follow that of the main lens. By selecting a calibration tower or a target at a suitable distance, the viewing axes of the auxiliary lens 10 and the main lens are adjusted to point in the same direction.
[0076] Optionally, the auxiliary lens 10 can be positioned above or below the main lens.
[0077] In some alternative implementations, the auxiliary lens 10 is positioned above the main lens.
[0078] Specifically, since the main lens needs to rotate 360° during the capture and measurement of the target, the auxiliary lens 10 is positioned above the main lens, allowing the azimuth angle of the auxiliary lens to follow the 360° rotation of the main lens and its pitch angle to be unrestricted. The auxiliary lens 10 can be fixed above the main lens with screws. Therefore, the installation position of the auxiliary lens 10 does not affect the original function of the main lens.
[0079] refer to Figure 8 and Figure 9 The onboard power distribution box is fixed above the main lens, and the auxiliary lens 10 can be fixedly installed above the onboard power distribution box.
[0080] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
