Portable three-dimensional temperature field reconstruction system based on infrared thermal imager and depth camera

Abstract

The invention relates to a portable three-dimensional temperature field reconstruction system based on an infrared thermal imager and a depth camera, which comprises a main processing unit, a temperature information acquisition unit and a three-dimensional point cloud information acquisition unit, wherein the main processing unit realizes data processing and software running by using a contained GPU device; the temperature information acquisition module realizes acquisition for object surface temperature information; and the three-dimensional point cloud information acquisition module realizes acquisition for object surface three-dimensional space information, the object surface temperature information and the object surface three-dimensional space information are transmitted to the main processing unit so as to be processed, and the processed information is displayed through a visualization upper computer. The portable three-dimensional temperature field reconstruction system can perform three-dimensional modeling on a scene online in real time, can enable infrared temperature field information to be fused with a three-dimensional model, and is significantly improved in construction effect compared with an operation of independently using an RGB-D depth camera or an infrared thermal imager.

Description

technical field [0001] The invention relates to a three-dimensional reconstruction technology, in particular to a portable three-dimensional temperature field reconstruction system based on an infrared thermal imager and a depth camera. Background technique [0002] The 3D reconstruction technology can realistically establish the virtual information space of the objective world in the computer, and generate valuable 3D shape information. Through the analysis, mining, retrieval and efficient utilization of these three-dimensional shape information, it can meet the needs of many major applications such as digital factories, digital cities, digital mines, cultural relics reconstruction, and disaster early warning. However, if the 3D model can contain more invisible information in addition to the information recognizable by the naked eye, it will be more valuable for the application of digital factories, such as detecting the operating status of equipment. As for invisible ligh...
