Method and device for measuring internal temperature of heap fermentation based on infrared temperature measurement

摘要

A device for measuring the internal temperature of heap fermentation includes an infrared thermal imaging camera, a distance detection camera, and a controller. The infrared thermal imaging camera obtains a temperature distribution image of a surface of a fermentation heap. The distance detection camera obtains a distance between the surface of the fermentation heap and the distance detection camera. The controller matches the temperature distribution image of the surface of the fermentation heap with the distance between the surface of the fermentation heap and the distance detection camera, performs semantic segmentation on the image after matching is completed, extracts a three-dimensional (3D) contour temperature map of the surface of the fermentation heap, corrects a surface temperature of the fermentation heap, and predicts an estimated internal temperature of the fermentation heap, such that the internal temperature of the fermentation heap is effectively and accurately predicted.
