That is to say, after the airport near-air video image collected by the camera is received, image recognition is carried out on the airport near-air video image to identify whether a target aircraft exists in the airport near-air video image, and if the target aircraft exists, it is indicated that an aircraft about to land exists above the airport.
S103, if the airport near-air video image contains the target aircraft, a control signal is output and used for controlling the navigation aid lamp to be turned on.
That is, when recognizing that there is an aircraft about to land in the airport near-air video image, the ground station sends a control signal, and the control signal may be sent to a navigation aid lamp controller, and the navigation aid lamp controller may control the navigation aid lamps, such as airport lights, apron navigation aid lamps, boundary lamps, etc., to be turned on according to the control signal, so that the pilot on the target aircraft may land smoothly and reliably at the apron, etc., according to the guidance of the navigation aid lamps.
According to the control method of the navigation aid lamp, the airport near-air video image can be acquired through the camera, whether the airport near-air video image contains the target aircraft or not is judged through recognition, whether the aircraft to be landed is over the airport or not is further determined, when the aircraft to be landed is judged, the control signal is output, the navigation aid lamp is automatically controlled to be turned on, and therefore the navigation aid lamp can be actively turned on when landing requirements exist without personnel intervention, configuration and cost of the airport personnel are reduced, and the target aircraft can be guaranteed to land smoothly.
Referring to fig. 2, in one embodiment of the present invention, step S102 includes:
s201, identifying the aircraft in the airport near-air video image.
S202, capturing a target image containing the aircraft.
S203, detecting whether the landing lamp in the target image is lighted.
And S204, if the landing lamp in the target image is lightened, judging that the airport near-air video image contains the target aircraft.
Typically, aircraft landing require that landing lights on the aircraft be illuminated, and civilian aircraft are typically equipped with two or more landing lights, typically on the landing gear leg, wing leading edge, or suitable fairing of the aircraft. The landing light is usually installed at a horizontal angle towards the right front, and the pitch angle is determined according to the attitude of the airplane.
In this embodiment, after receiving the airport near-air video image acquired by the camera, image recognition is performed on the airport near-air image to identify the aircraft in the airport near-air image. And then capturing a target image containing the aircraft, processing and analyzing the target image, judging whether the landing lamp in the target image is lighted, and if the landing lamp is lighted, indicating that the aircraft is the aircraft needing to land, namely the target aircraft.
In one embodiment of the present invention, step S201 includes: the method comprises the steps of extracting corner features of airport near-air video images, adopting an adaptive kernel clustering algorithm, clustering corners belonging to aircrafts into one class, clustering corners of a background into one class, calculating various clustering centers in an image two-dimensional space, removing isolated corners according to the distances from the various corners to the clustering centers, updating the centers, calculating the number of the corners of the images in a window with the clustering centers as the centers (the size of the window is slightly larger than that of the aircrafts), judging that the window images are aircrafts if the number of the corners is within a preset range, and effectively identifying the aircrafts under fuzzy scenes such as night by using the algorithm.
More specifically, referring to fig. 3, step S203 includes:
s301, determining the type of the aircraft in the airport near-air video image according to the shape of the aircraft in the target image, wherein the aircraft is a civil airplane or a civil helicopter.
S302, determining the position of the landing lamp on the aircraft in the target image according to the type of the aircraft.
S303, performing brightness calculation on the position of the landing lamp on the aircraft in the target image to judge whether the landing lamp on the aircraft in the target image is lighted.
Because the landing lights of the civil aircraft are arranged on the undercarriage and the wings, the landing lights on the wings are sequentially arranged along the extending direction of the wings, and the landing lights of the civil helicopter are generally arranged on the side surfaces of the undercarriage and the body, in the embodiment, the type of the aircraft is determined according to the shape of the aircraft in the target image, the position of the landing light can be ensured according to the type of the aircraft, and finally, whether the landing light is lightened or not can be judged by performing brightness calculation on the position.
In an embodiment of the present invention, step S103 further includes: calculating the current height position of the target aircraft according to the target aircraft in the airport near-air video image;
the output control signal includes: and outputting the control signal when the current height position is in a preset height range.
That is, after the target aircraft is determined to be included in the airport near-air video image, the current altitude position of the target aircraft may be calculated according to the target aircraft in the airport near-air video image. The higher the height of the target aircraft is, the smaller the image size in the airport near-air video image is, so that the height position of the target aircraft can be calculated according to the size of the target aircraft in the airport near-air video image. After the altitude position of the target aircraft is obtained, the altitude position is compared with a preset altitude range, if the altitude position is within the preset altitude range, a control signal is output to control the navigation lamp to be turned on, and therefore the turn-on time of the navigation lamp can be more reasonable, and resource balance is achieved.
In some embodiments of the invention, further comprising:
and if the airport near-air video image contains a target aircraft, sending VHF voice to the target aircraft, wherein the VHF voice is used for prompting and guiding a pilot of the target aircraft to land.
The ground station has a first VHF communication system (i.e., a very high frequency communication system) through which VHF speech can be transmitted, and the target aircraft has a second VHF communication system on which VHF speech transmitted by the first VHF communication system can be received.
That is to say, after the situation that the airport near-air video image contains the target aircraft is judged, the VHF voice can be actively sent to the target aircraft, and after the pilot on the target aircraft receives the VHF voice, the pilot can control the target aircraft to smoothly land on the parking apron and other positions of the airport according to the VHF voice prompt. In other words, in this embodiment, the VHF voice is actively transmitted, so that guidance of the pilot on the target aircraft is facilitated, and the target aircraft can smoothly land on the apron and other locations of the airport.
