The airborne positioning device includes: a rotor drone; a camera is installed on the rotor drone; a memory is used to store images transmitted by the camera; a comparison module is used to After comparing the image and the template, the deviation is sent to the control module; the control module is used to adjust the spatial position of the rotor drone and the attitude of the camera. The invention also discloses a remote measurement system and method using the above-mentioned positioning device and method. The invention has the advantages of high precision, simple structure, low cost and the like.

Description

technical field [0001] The invention relates to photoelectric analysis, in particular to an airborne indoor gas remote measurement system and method. Background technique [0002] At present, the methane telemetry instrument has been widely used in the detection of natural gas leakage. The basic principle adopted by the telemetry instrument is: by receiving and analyzing the optical signal absorbed by the gas in the area to be measured and reflected by the wall, to obtain the optical signal on the optical path. Gas information to be measured. In order to quantitatively express the absolute concentration of methane in the area to be measured, it is necessary to simultaneously measure the distance from the telemeter to the wall and the methane absorption signal on this path. The traditional ranging light source uses a laser that can emit 650nm light, and the detector uses silicon material, while the light source of the telemeter uses a laser that can emit 1651nm light, and th...

AI Technical Summary

Problems solved by technology

[0003] 1. The structure is complex, and it needs to be equipped with two sets of optical systems, which are used for distance measurement and signal absorption respectively, and weigh about 5 kg. For example, the telemeter of Hans in the United States weighs 5.8 kg;

[0004] 2. It cannot be used for the detection of indoor gases on each floor of the building

The disadvantage of this method is that it depends too much on the proficiency of the operator, and the positioning accuracy cannot be guaranteed

[0009] First of all, the UAV may deviate from the vertical direction during the climbing process, which will cause the distance between the UAV and the window to change;

[0010] Secondly, the UAV itself does not have an altimeter, so it can only rely on GPS positioning, and the positioning accuracy is limited. In some places where the GPS signal is not good, it is even impossible to locate;

[0011] In addition, the currently commonly used multi-rotor UAV may spin during the climbing process, which may cause the test equipment mounted on the UAV to be unable to face the user's window.

[0012] Based on the above-mentioned technical problems in the precise positioning of UAVs, UAVs have not yet been used in indoor gas telemetry on different floors
