Method for measuring surface temperature field of gangue mountain based on total station and thermal infrared imager

Abstract

The invention relates to a method for measuring a surface temperature field of a gangue mountain based on a total station and a thermal infrared imager, and belongs to the technical field of surveying and mapping and environmental monitoring. The method comprises the following steps of: dividing the gangue into a plurality of areas, wherein each area corresponds to one picture format of the thermal infrared imager; setting at least 5 to 6 marking points in each area; establishing a mapping control network by using the total station, and measuring spatial information of the marking points by using the total station and temperature information by using the thermal infrared imager at the same time on the mapping control points; and calculating spatial information of a designated temperature characteristic point by an interpolation method so as to draw the surface temperature field of the whole gangue mountain. In the method, a total station topography surveying and drawing technology and a thermal infrared imaging technology are coupled together, so quick measurement of the surface temperature of the gangue and accurate location of the spatial position of the temperature field can be realized; therefore, a basic support is provided for treating the spontaneous combustion gangue mountain.

Description

technical field [0001] The invention belongs to the technical field of surveying, mapping and environmental monitoring, and in particular relates to a method for measuring the surface temperature field of a coal gangue hill based on a total station and an infrared thermal imager. Background technique [0002] Spontaneously combusted coal gangue is very harmful to the environment and has great environmental risks. Therefore, the control of spontaneously combusted coal gangue has become a hot spot in current research. The key to the control of spontaneous combustion gangue is to find out the high temperature area and the ignition point, so as to take corresponding fire extinguishing and flame retardant countermeasures to achieve the purpose of treatment. [0003] Research on coal combustion and sulfide ore combustion at home and abroad shows that the main characterization parameter of combustion is temperature. Therefore, it is appropriate to use temperature detection to deter...

Problems solved by technology

Infrared thermal imaging cameras can obtain surface temperature parameters, but cannot obtain spatial information, that is, the spatial position of each temperature point cannot be determined, and must be coordinated with surveying and mapping technology
