基于COM组件技术的岩心图像在线三维重建

Online three-dimensional reconstruction of core images based on COM component technology

在石油、地质部门,很多重要的地质参数都来自于钻井出来的岩心,而岩心图像是钻井得到岩心后的第一手资料,在对岩心的研究中发挥着重要作用。但只观看岩心表面图像不够直观,无法看到岩心的实际形状,因此需要进行三维重建。而在钻井过程中不可避免地造成岩心受到一些破坏。为此提出一种对岩心图像先进行简单修复,然后采用OpenGL技术,基于COM组件的在线三维重建技术,使得地质专家不必亲临现场就可以查看岩心的三维图像。实践表明,岩心图像在线三维重建技术可应用于石油和地质部门。

In the departments of petroleum and geology, many important parameters come from the cores of rocks, and the core images which play a key role in the research on cores are the firsthand data after getting cores by drilling. But it is not enough to watch only the surface images of the cores for obtaining the authentic form of them. Therefore, the three-dimensional reconstruction is necessary. And some damages on the cores will inevitably occur during the drilling process. A sort of online three-dimensional reconstruction technology is put forward, which repairs the core images simply and then reconstructs the images by using OpenGL and the online three-dimensional reconstruction technology based on COM component technology. As a result, geologists can get three-dimensional images of the cores without being on the spot. Practices indicate the online three-dimensional reconstruction technology shows a big utility value in the departments of petroleum and geology.
