中文摘要:三维重建技术已在工业自动化领域得到了广泛的应用,但对于工业生产线中玻璃、锻造件等表面结构单一、高反光、无纹理的高温产品,利用传统的三维重建方法得到的三维重建结果往往不准确。这些高温物体会产生红外偏振自发辐射,提出了基于红外辐射偏振成像的目标三维重建方法。首先建立红外偏振辐射模型,分析目标表面红外辐射偏振态与目标表面法向量之间的关系,最后通过对法向量积分得到目标表面的三维形态。该方法不依赖于物体表面的纹理特征信息,对光照条件无要求且采集一次数据即可重构出目标表面的三维形态,易于实现,具有广阔的应用前景。

3D reconstruction method of target based on infrared radiation polarization imaging
Abstract:Three-dimensional reconstruction technology has been widely used in the field of industrial automation. However, traditional 3D reconstruction methods are difficult to obtain accurate results for high-temperature products in industrial production lines such as glass and forgings that are characterized by a single surface structure, high reflectivity and no texture, because these high temperature products generate infrared polarized radiation. I propose a three-dimensional reconstruction method of the target based on infrared radiation polarization imaging. First, I establish an infrared polarization radiation model, and analyze the relationship between the infrared radiation polarization state and the normal vector of the target surface. Finally, I obtain the three-dimensional morphology of the target surface by integrating the normal vectors. The method does not rely on the structure and texture information of the target surface, has low lighting requirements, and can reconstruct the 3D morphology of the target surface with only one data acquisition. Therefore, it is easy to implement and has a wide range of applications.
