基于VTK的红外热图等温线提取

INFRARED THERMAL IMAGE TEMPERATURE CONTOUR EXTRACTION BASED ON VTK

提出并实现了一种基于VTK(Visualization ToolKit)的红外图像等温线提取方法。首先对红外图像进行整体测温获得温度数据集,然后利用VTK提供的过滤器,实现等温线提取,最后利用VTK的数据接口获取等温线轮廓数据。本方法已经成功应用于红外序列图像自动配准和历史趋势分析系统中。实用表明,该方法简单、有效、稳定,具有一定推广应用价值。

This paper proposes an infrared image temperature contour extraction method based on VTK, and this has been realized. First, temperature on whole infrared image is measured and collected to a data-set file, then VTK Filter classes are utilized to extract temperature contour. The contour outline data are acquired through VTK data interface at last. This method has been successfully applied in an infrared image series automatic registration and historical tendency analysis system, which shows that it is simple, effective, stable and worth popularizing.
