Kinect Fusion过滤 [英] Kinect Fusion filtering

问题描述

很抱歉劫持这个帖子，但它完全适合我自己的问题。我有一个Kinect，在平面（桌面）前面60厘米。通过拍摄具有"深度基础"的屏幕截图来测量深度。采样并使用"Kinect Fusion
Explorer"。在这两种情况下，结果都是相似的（预期的结果），但实际上远远超出了上面提到的原始物体的~1.5mm。事实上，我在表面上会得到某种圆形波，这可能是由球面失真引起的。另外
还有大量的噪音，导致原始物体周围的总振幅约为1.5厘米。



所以我也会很开心能够在融合过程之前应用某种校准。有没有（简单）方法呢？



来自德国的问候。

至于你的问题，你会看到深度图像工件：

你在将帧传递给Fusion引擎之前，可以始终对数据应用某种类型的图像平滑。这是一个讨论这个的老线程。

Sorry for hijacking this thread, but it just fits my own question perfectly. I have a Kinect, 60cm in front of a planar surface (a tabletop). The depth is measured both by taking a screenshot with the "Depth Basics" sample and using the "Kinect Fusion Explorer". In both cases, the results are similar (what was expected) but really very far form those ~1.5mm of the original object you mentioned above. In fact I get some kind of circular waves on the surface, probably caused by spherical distortion. In addition to that there is massive noise, resulting in a total amplitude of ~1.5cm around the original object.

So I also would be very happy to be able to apply some sort of calibration prior to the fusion process. Is there a (simple) way to do that?

Greetings from Germany.

As for your issue, you are seeing depth image artifacts:

You can always apply some type of image smoothing on the data before passing the frame to the Fusion engine. Here is an older thread discussing this.
