Aircraft landing gear state judgment method based on image recognition

Abstract

The invention provides an aircraft landing gear state judgment method based on image recognition, and the method comprises the following steps: 1), continuously collecting an aerial target image through an image collection module erected on an aircraft runway; 2) identifying an airplane and the position of the airplane in the aerial target image by adopting an airplane identification model; 3) acquiring the flight state of the aircraft according to the group of image sequences obtained in the step 2); 4) extracting an aircraft image from the aircraft identification result; 5) identifying the undercarriage in the aircraft image by adopting an undercarriage identification model; 6) extracting an undercarriage image from the undercarriage recognition result, and 7) comprehensively judging whether the folding and unfolding state of the undercarriage is correct or not by combining the flight state of the aircraft and the undercarriage image. According to the invention, through accurate identification of the aircraft landing gear and in combination with the aircraft flight state, state judgment of the landing gear is effectively achieved, and the accuracy and stability of detection are improved.

Description

technical field [0001] The invention relates to the technical field of airport safety protection, in particular to a method for judging the retractable state of an aircraft landing gear based on image recognition technology. Background technique [0002] At present, the retractable state of the landing gear of the aircraft is mainly prompted by the indicating instrument on the aircraft. When the indicating instrument fails, the pilot will not be able to obtain the current state of the landing gear, thus causing a great safety risk. In order to ensure flight safety, ground personnel generally observe the aircraft through binoculars, manually confirm the retraction and retraction of the landing gear, and notify the pilot in time when the landing gear fails. However, this method is easily affected by environmental factors such as weather, light, and visibility. At the same time, observers are required to be highly focused, and a little carelessness can easily lead to safety acc...

Problems solved by technology

Although the status of the landing gear can be obtained through the image detection technology, there are situations where the position of the landing gear under different flight attitudes cannot be accurately identified, which is prone to false positives and false positives.
