The invention provides a non-contact aircraft fuel quantity measuring method and system. The measuring method includes the steps that a laser device is controlled to emit cross detection light into afuel tank; an image of a fuel surface in the fuel tank is acquired to obtain the coordinates of a cross light intersection in the image of the fuel surface in the fuel tank in an aircraft fuselage coordinate system; the coordinates of the cross light intersection in the image of the fuel surface in the fuel tank in the aircraft fuselage coordinate system are corrected according to the flight attitude of an aircraft to obtain the coordinates of the cross light intersection in the image of the fuel surface in the fuel tank in a reference coordinate system; the volume of fuel in the fuel tank isobtained according to a corresponding relationship between the coordinates of the cross light intersection in the image of the fuel surface in the fuel tank in the reference coordinate system and thequantity of fuel in the fuel tank. By means of the technical scheme, the problem that in the prior art, when the quantity of fuel in the fuel tank of the aircraft is detected, the accuracy of the detection result is low is solved.
Description
technical field [0001] The invention belongs to the technical field of aircraft fuel oil quantity measurement, and in particular relates to a non-contact aircraft fuel oil quantity measurement method and system. technical background [0002] The remaining fuel volume of the aircraft fuel tank is an important parameter for flight. According to it, the continuous flight time of the aircraft can be calculated. Therefore, real-time and accurate measurement and display of the remaining fuel volume of the aircraft fuel tank is very important to complete the flight mission. [0003] In terms of aircraft fuel measurement, capacitive fuel level sensors are mainly used at present. This kind of sensor has been soaked in oil for a long time and has a short service life. Because it uses mechanical methods to change the resistance value, the detection accuracy is not high, and there are also lead wires. The potential danger of explosion caused by discharge; the magnetic float level gauge ...
