Embodiment 1

[0018] A sampling cross positioning method for air pollution emission monitoring by unmanned aerial vehicles, comprising the following steps:

[0019] The first step: determine the distance between the infrared thermal imager and the smoke source; the selection of the baseline length (the distance between the infrared thermal imager and the smoke source) is based on the principle of ensuring that the infrared thermal imager can see the complete smoke plume threshold contour line, generally can be At about 500 meters, the two observation points should be selected on both sides of the smoke axis as much as possible, and the optical axis of the thermal instrument lens should be perpendicular to the average wind direction as much as possible;

[0020] The second step is to determine the relative position of the drone and the flare plume; use two infrared thermal imagers to monitor the relative position of the drone and the flare plume, and observe the center of the drone and the pl...

Abstract

The invention belongs to the technical field of air pollution monitoring and particularly relates to a method for sampling and intersecting positioning of a drone for air pollution emission monitoring. The method comprises 1, determining the distance between an infrared thermal imager and a smoke source, 2, determining the relative positions of a drone and torch smoke plume, 3, determining the flying height and position of the drone through laser, and 4, carrying out sampling through the drone. The method fast determines the acquisition height and position of the drone through the infrared thermal imager and a laser pen, has high accuracy, is easy to operate and realizes a low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of air pollution monitoring, and in particular relates to an unmanned aerial vehicle sampling cross positioning method for air pollution discharge monitoring. Background technique [0002] At present, there are many types and quantities of enterprises in chemical parks, and there are many types of characteristic pollutants, most of which are toxic and harmful gases. There is no effective supervision method for the discharge of VOCs and odorous gases, and there is no information on the distribution and transmission of high-altitude pollutants in chemical parks. Better monitoring methods, daily environmental management still rely on traditional online monitoring and ground monitoring data, research on environmental three-dimensional monitoring methods is relatively weak, gas monitoring types and point coverage are not comprehensive, monitoring level and energy efficiency need to be improved urgently.
