深度相机帧率挣扎 [英] Depth Camera framerate struggling

问题描述

我遇到了问题，无法通过谷歌找到任何可靠的答案。我已经使用了kinect for windows SDK，因为我们在儿童博物馆使用它，我经常工作，直到现在都没有任何问题。我一直在家里和工作中使用桌面上的
，他们都使用彩色和深度相机管理大约30fps的帧速率。我最近买了一台联想Y510P i7四核geforce 755M SLI，这应该让我的工作电脑免受i3双核intel + b $ b HD 4000的影响，并且比家里的桌面强，Phenom II x6 Geforce 550ti。这些机器分别运行Windows 8.1，Windows 7 Pro和8.1 Pro。我以为我的笔记本电脑能够处理kinect没有问题，但深度相机帧率在这个地方都是
，通常是10 fps以下有时挂在1FPS甚至0。是否任何人都有任何见解为什么会发生这种情况。我尝试卸载SDK并重新安装。我的笔记本电脑处理器有点慢，但我从默认的2.4开始超频
到3 gHz。 

我尝试使用kinect资源管理器，字面上除了深度图像帧率很差，但是当我尝试深度基础示例时它以30 fps运行。当我尝试运行我编写的仅使用深度流的程序时，我遇到
同样的问题。该程序在所有其他机器上运行正常，因此它显然是我的笔记本电脑特有的问题，可能是驱动程序问题还是什么？ 

解决方案

DepthBasics-D2D或D3D样本是否表现出相同的问题？骨骼跟踪怎么样？

原始的Kinect深度/颜色数据直接来自相机/ USB2总线。然后，运行时处理深度数据以生成骨架。如果您能够毫无问题地跟踪用户，那么问题将是针对该特定
安装的环境问题。您是否有任何第三方安全或监控类型的应用程序可能试图挂钩到api？ 

I am having a problem and couldn't find any solid answers through google. I have worked with the kinect for windows SDK plenty since we use it at the children's museum I work at pretty regularly and haven't had any problems till now. I had been working on a desktop both at my house and at work and they both managed framerates of about 30fps with both color and depth cameras. I recently bought a Lenovo Y510P i7 quad-core geforce 755M SLI which should blow my work computer out of the water i3 dual core intel HD 4000 and is stronger than my desktop at home, Phenom II x6 Geforce 550ti. The machines run Windows 8.1, Windows 7 Pro, and 8.1 Pro respectively. I thought my laptop would be able to handle the kinect no problem, however the depth camera framerate is all over the place and is usually sub 10 fps sometimes hanging at 1FPS or even 0. Does any one have any insight as to why this could be happening. I tried uninstalling the SDK and reinstalling. My laptops processor is a bit slower but I have it overclocked up to 3 gHz from the default 2.4. 

I try using the kinect explorer and literally everything works except the depth image framerate is bad, though when I try the depth basics example it runs at 30 fps. When I try to run a program that I wrote that only uses the depth stream however, I encounter the same problem. The program works fine on all other machines so its clearly a problem specific to my laptop, could it be a driver issue or what? 

解决方案

Does DepthBasics-D2D or D3D samples exhibit the same issues? What about skeletal tracking?

The original Kinect depth/color data come directly off the camera/USB2 bus. Depth data is then processed by the runtime to generate skeletons. If you are able to track users without issues, then the issue is going to be environmental to that particular install. Do you have any third party security or monitor type applications that could be trying to hook into the apis?
