This paper aims to study the construction method of a three-dimensional temperaturedistribution reconstruction system based on depth and thermal infrared information. Initially, the traditional calibration methods were not straightforward because depth and thermal infrared cameras were not sensitive to color calibration plates. Therefore, a depth and thermal infrared camera calibration board is designed to perform depth and thermal infrared camera calibration. Secondly, the three-dimensional temperaturedistribution is built based on spatial affine transformation matching. The Local feature descriptor is proposed. In addition, the three-dimensional temperaturedistribution is calculated by local feature matching. Finally, the optimization of 3dtemperaturedistribution reconstruction is completed based on autoregressive (AR) model. Experimental results show that a three-dimensional temperaturedistributionmodel can be built accurately based on this method with strong robustness.

This paper studies the construction of 3dtemperaturedistribution reconstruction system based on the binocular visual technology. First of all, since the thermal infrared camera is only sensitive to temperature, the traditional calibration method cannot be directly used in it. Therefore, the paper designs a thermal infrared camera calibration board to complete the calibration of the thermal infrared camera. Then, in terms of stereo matching, it further studies the traditional belief propagation algorithm and improves its smooth model, so as to optimize the mismatching rate greatly. Finally, in terms of the 3dmodel construction, it constructs the corresponding relationship between the points on the 3dmodel and the pixels on the temperature images based on the known thermal infrared camera and the space position information of the visible light camera and maps the temperature information to the 3dmodel. Experimental results show that the method can accurately construct the 3d temperature distribution model and the model has strong robustness.

This paper aims to study the construction of 3dtemperaturedistribution reconstruction system based on depth and thermal infrared information. Initially, a traditional calibration method cannot be directly used, because the depth and thermal infrared camera is not sensitive to the color calibration board. Therefore, this paper aims to design a depth and thermal infrared camera calibration board to complete the calibration of the depth and thermal infrared camera. Meanwhile a local feature descriptors in thermal anddepth images is proposed. The belief propagation matching algorithm is also investigated based on the space affine transformation matching and local feature matching. The 3d temperature distribution model is built based on the matching of 3d point cloud and 2d thermal infrared information. Experimental results show that the method can accurately construct the 3d temperature distribution model, and has strong robustness.
