英文摘要： For the airtight device applied in the complex metallurgical process, this project will investigate a method to detect and rebuild the three-dimensional temperature field based on multi-source information fusion. First, we establish a relational model and an equation correlating multi-source detection information with three-dimensional temperature distribution by studying the working principle of detecting equipments and the mechanism of three-dimensional heat transfer in the airtight device. And then we analyze the uncertainty and reliability of the detection model. Next, we explore a method based on multi-source information fusion for shape recognizing and locating heat sources in the airtight device. Also, we present a way of dynamic mesh generation of three-dimensional space based on the shape and gray scale. Thus we work out the dimension and coefficient of the relational model. And then, we propose a method based on multi-source information fusion for solving the relational equations of temperature detection that featured ill-poseness and over-determination, and devise a reconstruction technique of three-dimensional temperature field. Therefore, we reduce over-determination and singularity in relational equations and achieve precisely the temperature of three-dimensional mesh. After that, we design a compu
