Abstract

The invention provides a temperature detection method, device and equipment. The method comprises the following steps: periodically acquiring an initial temperature value of a target position through a thermal imaging sensor; when the target vehicle arrives at the target position, determining whether the target vehicle is a vehicle of a specified type, and if yes, acquiring a plurality of visible light images of the target vehicle through a visible light sensor; for each visible light image, based on the acquisition time of the visible light image and the acquisition time of the initial temperature value, selecting a target temperature value corresponding to the visible light image from all the initial temperature values; and determining the temperature values of a plurality of temperature measurement points of the target vehicle based on the target temperature values corresponding to the plurality of visible light images, and determining the temperature value of the target vehicle based on the temperature values of the plurality of temperature measurement points. According to the technical scheme, whether the target vehicle is the dangerous goods transportation vehicle or not is automatically determined, and high-temperature early warning in the driving process of the dangerous goods transportation vehicle is achieved.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a temperature detection method, device and equipment. Background technique [0002] The visible light sensor is a sensor used to collect visible light images. Visible light images are images collected in the range of visible light (visible light is the part of the electromagnetic spectrum that the human eye can perceive, such as wavelengths between 400 and 760nm). The images that can be seen contain rich spectral information. [0003] A thermal imaging sensor is a sensor used to collect thermal imaging images. Thermal imaging images are not images collected in the visible light range, but images related to the surface temperature of objects. For example, objects in nature can radiate infrared rays. By detecting infrared signals in specific bands, the signals are converted into images that can be distinguished by the human eye. This image is a thermal imaging i...
