本文介绍了一种“减少现实”技术，用于删除对象或对象集合，并将其替换为适当的背景图像。减少现实可以被认为是许多混合和增强现实应用的重要组成部分。我们的目标应用是使用增强现实（AR）来改造工业工厂的程序。在单个参考图像上描绘感兴趣的对象或区域。一个paraprospective投影模型被用来生成正确的背景从多个校准的场景视图。我们提出的方法来处理近似平面的背景与不同的方向。我们还提出了一个多分辨率的方法来处理非平面背景。不同的实验结果表明了算法的成功和局限性。对水处理和发电厂的真实的数据的处理结果表明了该方法的实用性。
This paper introduces a "diminished reality" technique for removing an object or collection of objects and replacing it with an appropriate background image. Diminished reality can be considered an important part of many mixed and augmented reality applications. Our target application is the use of augmented reality (AR) to revamp procedures in industrial plants. An object or a region of interest is delineated on a single reference image. A paraperspective projection model is used to generate the correct background from multiple calibrated views of the scene. We propose methods to deal with approximately planar backgrounds with different orientations. We also propose a multi-resolution approach to deal with non-planar backgrounds. Different sets of experimental results demonstrate the success and limits of the algorithms. Results on real data from water treatment and power plants show the usefulness of this method for industrial applications.
