如何将深度变为颜色？ [英] How to mapp Depth to Color ?

问题描述

我是Kinect的初学者，我使用这个设备3天，所以
了解我。



我有这个问题。我有彩色图像阵列和深度图像阵列。我在彩色图像上找到了一些东西（项目）（Xincolor，Yincolor），我知道距离Kinect有多远，所以我需要从Xindepth和Yindepth获得价值Z，但是我需要在
之前改变大小数组深度。 我找到了一些人们使用CoordinateMapper.MapDepthFrameToColorSpace的解决方案。我也尝试使用这个方法，但是这个方法返回我的数组大小与数组深度相等。和 在返回的数组中，奇怪的是
值：  X：175.26976 Y：-116.437988。

有人可以帮助我吗？



而且，对不起我的英语。

I'm beginner in Kinect, I work with this device 3 days,, so be understanding for me.

I have that problem. I have array with color image and array with depth image. I have found something (item) on color image (Xincolor, Yincolor) and i'd know how far it is from Kinect, so I need get value Z, from Xindepth and Yindepth, Buth before I need to change size of array depth.  I found some solution where people used CoordinateMapper.MapDepthFrameToColorSpace. I try use this method also, buth this method return me array with size is equal size of array depth. And  in returned array, are strange value :  X:175.26976 Y:-116.437988.

Some one can help me ?

And, sorry for my english.

基本上该函数的结果为您提供了查找点，其中深度可能有也可能没有色点，因为相机空间没有重叠或可能落在红外阴影上。关键是要确认点落在颜色框内
范围内的偏移范围内并获取该颜色点值。

basically the result of the function provides you lookup points where the depth may or may not have a color point because of the camera space doesn't overlay or may fall onto a ir shadow. The key is to confirm the points fall within range of an offset within the color frame and take that color point value.

至于确定特定深度点的位置色点，更容易获取x，y偏移并将其映射到深度：

MapColorFrameToCameraSpace 或
MapColorFrameToDepthSpace  这会更快一些，因为您处理的是一组更小的数据。 CameraSpace将在三个维度上为您提供更多与相机的真实距离。

As for determining what the depth point is for a particular color point, it is easier to take an x,y offset and map that to depth: MapColorFrameToCameraSpace or MapColorFrameToDepthSpace this will be a bit faster as you are dealing with a much smaller set of data. CameraSpace will give you more of a real-world distance from the camera in all 3 dimensions.
