Abstract

The invention relates to the technical field of construction monitoring, in particular to an asphalt mixture construction temperature real-time detection method and system based on an unmanned aerialvehicle, and the method comprises the steps: obtaining a visible light image and an infrared image photographed by a bifocal camera on the unmanned aerial vehicle; identifying an asphalt laying area image in the visible light image; obtaining a mapping relationship between the same group of visible light images and infrared images, calculating first position information of the asphalt laying areaimage in the same group of infrared images according to the mapping relationship, and marking a to-be-detected area in the infrared images according to the first position information; and calculatingfirst temperature information of the to-be-detected area. The method and system have the effect of overcoming the defect of inaccurate temperature detection of the detection head.

Description

technical field [0001] This application relates to the technical field of construction monitoring, in particular to a method and system for real-time detection of asphalt mixture construction temperature based on drones. Background technique [0002] With the gradual advancement of urbanization, road construction has also gradually increased with the process of urbanization. At present, road construction generally lays asphalt mixture on the road surface to increase the smoothness and water permeability of the road. Asphalt mixture The temperature of the material is an important internal factor in the formation of the strength of the asphalt pavement, and the temperature of the asphalt mixture includes the mixing temperature, delivery temperature, transportation temperature, paving temperature, rolling temperature, and rolling end temperature. [0003] For real-time temperature detection during rolling, generally the probe head of the temperature sensor is pressed into the a...
