Embodiment

[0022] Example: The best embodiment of the present invention, aircraft horizontal laser measurement system, is made up of laser positioning device 1, horizontal reference coordinate point 2, horizontal measurement point 3 and computer 4, is provided with at least four horizontal reference coordinate points 2 around the aircraft, The horizontal reference coordinate point 2 is about 3-5 meters away from the fuselage, and there is no obstacle blocking the laser beam. A laser positioning device 1 is set on one side of the aircraft to be measured, and several horizontal measurement points 3 are set on the aircraft. The horizontal measurement points 3 are the measurement values ​​required for leveling each aircraft, which are generally given when the aircraft is designed. quantity and location. The positions are generally distributed in positions such as the front section, the middle section, the vertical tail, the empennage and the wing of the fuselage, and the laser positioning ...

Abstract

The invention discloses a horizontal laser measurement system and a method for an airplane. The horizontal laser measurement system is composed of a laser locating device, a horizontal reference coordinate point and a horizontal measurement point. The horizontal laser measurement system is characterized in that: at least four horizontal reference coordinate points are arranged around the airplane; the laser locating device is arranged at one side of the airplane; a plurality of horizontal measuring points are arranged on the airplane; and the laser locating device is connected with a computer. In a measuring process, the value of each measuring point is produced by a laser tracker according to the laser reflection principle, so that the measurement error caused by manual operation is reduced, and the measurement value is more accurate.

Description

technical field [0001] The invention relates to measurement technology, in particular to the data acquisition of aircraft level measurement by using a laser positioning device, and in particular to an aircraft level laser measurement system and method. Background technique [0002] Existing aircraft level measuring method is to adopt theodolite, measuring tape, steel ruler and plumb etc. Use one end of the plumb to touch the measuring point, then adjust it to be vertical with a steel ruler or a tape measure to be flush with the vertical line, and use the theodolite to read the relative reference value of the measuring point. However, the measurement operations are all performed by multiple staff members. The theodolite needs multiple positionings to complete the measurement of all the measurement points of the aircraft during the measurement process of the whole aircraft. The operation takes a long time and human factors have a great influence on the accuracy of the values. ...
