Description

Technical Field

[0001] This invention belongs to the field of alarm detection technology, and in particular relates to a key airspace photoelectric bird monitoring and early warning system and method. Background Technology

[0002] With the continuous development of aviation technology and the increasing prosperity of the aviation market, night flight services have shown a rapid growth trend in the past few years. However, the development of night flights also faces some challenges, such as the shift in airport bird observation work from primarily daytime observation to all-day observation.

[0003] Traditional birdwatching methods rely primarily on human observation with the naked eye or telescopes during the day, and on handheld infrared sighting devices at night. These methods are limited by human vision, reaction speed, and physical strength, resulting in low efficiency. Observers may need to enter dangerous areas such as swamps and forests, posing safety risks. Relying on manual observation or ordinary cameras makes it difficult to achieve 24-hour continuous observation. The ability to continuously observe is insufficient due to limitations in personnel physical strength and energy. At night, the observation distance is limited by the aperture and focal length of the handheld infrared sighting device. Furthermore, observation data cannot be recorded and saved in real time, making subsequent review and analysis difficult. In practical applications, birdwatching in key airspaces (such as aircraft ascent and descent routes) is particularly important. Therefore, there is an urgent need for a system that can operate continuously day and night, monitor and record key airspaces in real time, and report the location of bird targets. Summary of the Invention

[0004] This invention provides a key airspace photoelectric bird monitoring and early warning system and method to solve the problems of low observation efficiency, difficulty in achieving 24-hour uninterrupted observation, insufficient continuous observation capability, limited nighttime observation distance, and inability to record and save data in real time in traditional airport bird monitoring methods.

[0005] Firstly, a key airspace photoelectric bird monitoring and early warning system is provided, the system comprising:

[0006] Fixed splicing infrared monitoring device, visible light and infrared detection pan-tilt unit, remote control switch, image processing server, and display control server; among which...

[0007] The display control server is used to power on and start the fixed splicing infrared monitoring device and the visible light and infrared detection pan-tilt unit to work normally via the remote control switch;

[0008] The fixed splicing infrared monitoring device is used to transmit real-time images of bird activity in a specific airspace to the image processing server.

[0009] The image processing server is used to perform target monitoring and identification, pairing, and binocular intersection calculation on the received real-time bird images, calculate the target's position information in three-dimensional space, and send it to the visible light and infrared detection pan-tilt unit.

[0010] The visible light and infrared detection gimbal is used to adjust the observation direction to the target position after receiving the target's position information in three-dimensional space, and to conduct further tracking observation and data collection.

[0011] Secondly, a method for monitoring and early warning of bird activity in key airspaces using photoelectric sensors is provided, the method comprising:

[0012] The display control server powers on the fixed splicing infrared monitoring device and the visible light and infrared detection PTZ unit via a remote control switch, starting them to work normally.

[0013] Fixed splicing infrared monitoring devices transmit real-time images of bird activity in a specific airspace to an image processing server;

[0014] The image processing server performs target monitoring and identification, pairing, and binocular intersection calculation on the received real-time bird images, calculates the target's position information in three-dimensional space, and sends it to the visible light and infrared detection pan-tilt unit.

[0015] After receiving the target's position information in three-dimensional space, the visible light and infrared detection gimbal turns its observation direction to the target's position for further tracking, observation, and data acquisition.

[0016] This invention provides a key airspace photoelectric bird monitoring and early warning system and method. It can monitor key areas in real time through a fixed infrared monitoring device, continuously track targets through visible light and infrared detection PTZ, display the target's position on an electronic map in real time through an image processing server and desktop computer, and record image data through a hard disk recorder. This can meet the airport's need for continuous day and night monitoring and recording of key airspace and reporting of bird target locations.

[0024] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0025] To improve the ability to monitor bird activity in specific airspaces, this invention provides a key airspace photoelectric bird monitoring and early warning system and method.

[0026] Figure 1 A schematic diagram of a key airspace photoelectric bird monitoring and early warning system according to an embodiment of the present invention is shown below. Figure 1 The system includes:

[0027] Fixed splicing infrared monitoring device, visible light and infrared detection pan-tilt unit, remote control switch, image processing server, and display control server; among which...

[0028] The display control server is used to power on and start the fixed splicing infrared monitoring device and the visible light and infrared detection pan-tilt unit to work normally via the remote control switch;

[0029] The fixed splicing infrared monitoring device is used to transmit real-time images of bird activity in a specific airspace to the image processing server.

[0030] The image processing server is used to perform target monitoring and identification, pairing, and binocular intersection calculation on the received real-time bird images, calculate the target's position information in three-dimensional space, and send it to the visible light and infrared detection pan-tilt unit.

[0031] The visible light and infrared detection gimbal is used to adjust the observation direction to the target position after receiving the target's position information in three-dimensional space, and to conduct further tracking observation and data collection.

[0032] In one specific embodiment, the system further includes a switch, a hard disk recorder, and several desktop computers;

[0033] Each set of two fixed splicing infrared monitoring devices, one visible light and infrared detection pan-tilt unit, one remote control switch, and one switch constitutes a real-time monitoring unit; a set of one image processing server, one display control server, one hard disk recorder, one switch, and multiple desktop computers constitutes a central control unit.

[0034] Among them, two fixed splicing infrared monitoring devices simultaneously observe key airspaces, and the actual observation areas are basically the same to ensure the maximum solvable area.

[0035] Two fixed splicing infrared monitoring devices, one visible light and infrared detection pan-tilt unit, and one remote control switch in the real-time monitoring unit are all connected to the switch in the real-time monitoring unit; one image processing server, one display control server, and one hard disk recorder are connected to the switch in the central control unit; the switches are connected to each other via fiber optic or network cables, so that all devices are in the same local area network and can communicate with each other.

[0036] In one specific implementation, since the locations where stations can be placed on airport runways are generally close (about 20 meters apart), the baseline of the two stations is generally short, and the imaging positions of the targets at the two stations are approximately the same. Image pairing can increase the target pairing accuracy through local windowing matching. Specifically, one station can be used as a reference station. After detecting all targets, a windowing rule can be set, such as dividing a 29*29 square area with each target as the center. When a target from the other station is within this area, the target is allowed to participate in subsequent signal-to-noise ratio matching, grayscale value matching, etc.

[0037] See binocular intersection calculation Figure 2 The calculation method is as follows:

[0038] Let O l and O r Let X and Y be the optical centers of the two stations, respectively, and let X be the imaging coordinates of P at the two stations. l and X r The difference PP′ is calculated using the following formula:

[0039] PP′=BX l +X r

[0040] Therefore, we can deduce that:

[0041]

[0042] Right now:

[0043]

[0044] Where B is the distance between the optical centers of the two stations, measured on-site using differential GPS, and f is the focal length;

[0045] The image processing server is also used to compress and stream the real-time bird images sent by the fixed splicing infrared monitoring device and send them to the display control server and the hard disk recorder.

[0046] The visible light and infrared detection gimbal is also used to send real-time images of observed bird activity to a display control server and a hard disk recorder.

[0047] In one specific embodiment, the display control server is further configured to:

[0048] Receive the target's position information in three-dimensional space calculated by the image processing server; and

[0049] The embedded bird monitoring system software plots the target on an electronic map based on the received location information of the target in three-dimensional space for observation; and

[0050] As the web server for the bird monitoring management system software, other desktop computers on the local area network access and display the bird monitoring management system software on the server via a designated IP address; and

[0051] It automatically collects bird information based on time, region, and spatial altitude, and outputs bird information reports.

[0052] In one specific embodiment, the hard disk recorder is used for

[0053] Automatically stores real-time bird activity images from visible light and infrared detection pan-tilt units; and

[0054] Real-time bird images from a fixed-slice infrared monitoring device are automatically stored, compressed, and streamed by an image processing server; and

[0055] Search for and replay recorded image data by date and time.

[0056] To better understand the present invention, the implementation process of the present invention will be described below in conjunction with specific embodiments.

[0057] The key airspace photoelectric bird monitoring and early warning system provided in this embodiment of the invention:

[0058] The system includes: fixed-position infrared monitoring devices, visible light and infrared detection pan-tilt units, remote control switches, switches, image processing servers, display control servers, hard disk recorders, and desktop computers. Each set of two fixed-position infrared monitoring devices, one visible light and infrared detection pan-tilt unit, one remote control switch, and one switch constitutes a real-time monitoring unit; each set of one image processing server, one display control server, one hard disk recorder, one switch, and multiple desktop computers constitutes a central control unit. Depending on actual needs, one central control unit can be paired with multiple real-time monitoring units.

[0059] The hardware components of real-time monitoring units 1 through n are completely identical. The hardware components of the two fixed-type splicing infrared monitoring devices in each group of real-time monitoring units are also completely identical. Desktop computers 1 through n are compliant desktop computers with network port communication capabilities and that meet the requirements of the local site.

[0060] Two sets of fixed, spliced ​​infrared monitoring devices simultaneously observe key airspace. The actual observation areas of the two sets of fixed, spliced ​​infrared monitoring devices should be basically the same to ensure the maximum observation area. All devices in the key airspace photoelectric bird monitoring and early warning system are connected to their corresponding switches. The switches are connected to each other via fiber optic cables, network cables, etc., meaning all devices are on the same local area network to achieve data communication.

[0061] When the key airspace photoelectric bird monitoring and early warning system is in operation, two fixed, spliced ​​infrared monitoring devices transmit real-time images to the image processing server of the central control unit. The image processing server performs target monitoring and identification, pairing, and binocular intersection calculation to determine the target's position information in three-dimensional space; the images are then compressed and streamed. Specifically, the target's position information in three-dimensional space is sent to the display control server and the visible light and infrared detection pan-tilt unit; the compressed and streamed images from the fixed, spliced ​​infrared monitoring devices are sent to the display control server and the hard disk recorder. After receiving the target's position information in three-dimensional space, the visible light and infrared detection pan-tilt unit can adjust its observation direction to the target's location for further tracking, observation, and data acquisition. The visible light and infrared detection pan-tilt unit then sends the observed real-time images to the display control server and the hard disk recorder.

[0062] The display control server can control the remote control switch to power on / off the equipment in the real-time monitoring unit; it can control the visible light and infrared detection pan-tilt units to rotate continuously 360°×n in azimuth and -10° to +90° in pitch, allowing for manual observation of nearby bird activity; the display control server has embedded bird management system software that can plot the target on an electronic map based on the received target's location information in three-dimensional space for easy observation; the display control server can automatically collect bird activity information by time, region, and spatial altitude, and output bird activity reports; the display control server also serves as the web server for the bird management system software, allowing other desktop computers on the local area network to access the bird management system software on the display control server via a specified IP address.

[0063] The hard disk video recorder can automatically store real-time images from visible light and infrared detection pan-tilt units; it can also automatically store real-time images from fixed spliced ​​infrared monitoring devices compressed and streamed by an image processing server. Recorded image data can be retrieved and played back by date and time.

[0064] In one embodiment, the fixed splicing infrared monitoring device, visible light and infrared detection pan-tilt unit, switch, and remote control switch are placed near the area to be monitored to observe key airspace and transmit real-time images to the central control unit.

[0065] In one embodiment, the image processing server, display control server, switch, and hard disk recorder are placed in the monitoring room for remote device control and data analysis.

[0066] The fixed splicing infrared monitoring device is used for real-time monitoring of key airspaces. It can report bird activity in a timely manner. Its detector is an infrared detector, which can achieve uninterrupted monitoring day and night.

[0067] The visible light and infrared detection gimbal is used for monitoring and early warning of areas near key airspaces. After receiving target location information, it can turn the observation direction to the target direction and track the target, observing the target's flight direction and trajectory, providing information support for further avoidance and evasion measures.

[0068] The visible light and infrared detection gimbal includes a visible light camera and an infrared thermal imager. Its purpose is to analyze information such as the species and posture of the target bird during the day through the visible light camera, and to detect and track the target both day and night through the infrared thermal imager.

[0069] The necessity of the fixed splicing infrared monitoring device lies in its fixed observation direction, enabling real-time observation of key areas with strong real-time performance but limited observation range.

[0070] The necessity of the visible light and infrared detection gimbal lies in its ability to rotate 360°×n in azimuth and -10°×n in pitch, enabling it to observe and search for targets over a wide area. It can continuously track targets detected by fixed-type spliced ​​infrared monitoring devices and continue to observe targets even after they have left the field of view of the fixed-type spliced ​​infrared monitoring devices, determining whether it is necessary to drive them away or avoid them.

[0071] The fixed-time splicing infrared monitoring device and the visible light and infrared detection pan-tilt unit are complementary in their advantages.

[0072] In one embodiment, the desktop computer is placed in the duty room, observation post, control tower, etc., and can remotely access the bird management system software of the display control server to view the location of the target on the map in real time.

[0073] The number of desktop computers is related to the number of locations that require real-time bird data; one desktop computer can be placed at each location that requires real-time bird data.

[0074] When the key airspace photoelectric bird monitoring and early warning system is in operation, the display control server controls remote control switches to power on the fixed spliced ​​infrared monitoring devices and the visible light and infrared detection pan-tilt units. The two fixed spliced ​​infrared monitoring devices transmit real-time images to the image processing server of the central control unit. The image processing server performs target monitoring and identification, pairing, and binocular intersection calculations to determine the target's position information in three-dimensional space; the images are then compressed and streamed. Specifically, the target's position information in three-dimensional space is sent to the display control server and the visible light and infrared detection pan-tilt units; the compressed and streamed images from the fixed spliced ​​infrared monitoring devices are sent to the display control server and the hard disk recorder. After receiving the target's position information in three-dimensional space, the visible light and infrared detection pan-tilt units can adjust their observation direction to the target's location for further tracking, observation, and data acquisition. The visible light and infrared detection pan-tilt units then send the observed real-time images to the display control server and the hard disk recorder. The display and control server controls the visible light and infrared detection pan-tilt units to rotate continuously 360°×n in azimuth and -10° to +90° in pitch, allowing manual observation of nearby bird activity. The server incorporates bird management system software that plots targets on an electronic map based on their 3D spatial location information for easy observation. It automatically compiles bird activity statistics by time, region, and spatial altitude, and outputs bird activity reports. The server also serves as a web server for the bird management system software, allowing other desktop computers on the local area network to access the software via a specified IP address. The hard disk recorder automatically stores real-time images from the visible light and infrared detection pan-tilt units and also automatically stores real-time images from the fixed-type splicing infrared monitoring device compressed and streamed by the image processing server. Recorded image data can be retrieved and played back by date and time.

[0075] This invention provides a key airspace photoelectric bird monitoring and early warning system. It can monitor key areas in real time through a fixed infrared monitoring device, continuously track targets through visible light and infrared detection PTZs, display the target's position on an electronic map in real time through an image processing server and a desktop computer, and record image data through a hard disk recorder. This can meet the airport's need for continuous day and night monitoring and recording of key airspace and reporting of bird target locations.

[0076] Based on the same inventive concept, this invention also provides a method for monitoring and early warning of bird activity in key airspace using photoelectric sensors, see [link to relevant documentation]. Figure 3 The method includes:

[0080] S306: After receiving the target's position information in three-dimensional space, the visible light and infrared detection gimbal turns its observation direction to the target's position for further tracking, observation, and data acquisition.

[0082] Each set of two fixed splicing infrared monitoring devices, one visible light and infrared detection pan-tilt unit, one remote control switch, and one switch constitutes a real-time monitoring unit; a set of one image processing server, one display control server, one hard disk recorder, one switch, and multiple desktop computers constitutes a central control unit.

[0083] Among them, two fixed splicing infrared monitoring devices simultaneously observe key airspaces, and the actual observation areas are basically the same to ensure the maximum solvable area.

[0084] Two fixed splicing infrared monitoring devices, one visible light and infrared detection pan-tilt unit, and one remote control switch in the real-time monitoring unit are all connected to the switch in the real-time monitoring unit; one image processing server, one display control server, and one hard disk recorder are connected to the switch in the central control unit; the switches are connected to each other via fiber optic or network cables, so that all devices are in the same local area network and can communicate with each other.

[0097] This invention provides a method for monitoring and early warning of bird activity in key airspaces using photoelectric sensors. A fixed infrared monitoring device enables real-time monitoring of key areas, while visible light and infrared detection PTZs continuously track targets. An image processing server and desktop computer display the target's location on an electronic map in real time, and a hard disk recorder records image data. This method meets the airport's need for continuous day and night monitoring and recording of key airspaces, and for reporting bird activity target locations.
