我已经安装了openni2.2,nite2.2和kinect SDK 1.6以及Simpleopenni库进行处理。除了红外图像外,一切都很好 - 它根本不存在。这真的很奇怪,因为同时我可以清楚地看到深度图像(深度图像在逻辑上需要红外摄像机和投影仪工作才能运行)。所以我假设驱动程序或软件有问题?我想使用 kinect 作为红外相机。请帮忙,下面我附上我的测试代码:

import SimpleOpenNI.*;
SimpleOpenNI context;
void setup()
{
context = new SimpleOpenNI(this);
// enable depthMap generation
if(context.enableDepth() == false)
{
println("Can't open the depthMap, maybe the camera is not connected!");
exit();
return;
}
// enable ir generation
if(context.enableIR() == false)
{
println("Can't open the depthMap, maybe the camera is not connected!");
exit();
return;
}
background(200,0,0);
size(context.depthWidth() + context.irWidth() + 10, context.depthHeight());
}
void draw()
{
// update the cam
context.update();
// draw depthImageMap
image(context.depthImage(),0,0);
// draw irImageMap
image(context.irImage(),context.depthWidth() + 10,0);
}
这完成了这项工作:
context.enableIR(1,1,1);
我有完全相同的问题。这不是一个解决方案,但我最接近从 kinect 获取红外图像的方法是从深度图像中获取点云那解决方案就在这里
import SimpleOpenNI.*;
import processing.opengl.*;
SimpleOpenNI kinect;
void setup()
{
size( 1024, 768, OPENGL);
kinect = new SimpleOpenNI( this );
kinect.enableDepth();
}
void draw()
{
background( 0);
kinect.update();
image(kinect.depthImage(),0,0,160,120);//check depth image
translate( width/2, height/2, -1000);
rotateX( radians(180));
stroke(255);
PVector[] depthPoints = kinect.depthMapRealWorld();
//the program get stucked in the for loop it loops 307200 times and I don't have any points output
for( int i = 0; i < depthPoints.length ; i+=4)//draw point for every 4th pixel
{
PVector currentPoint = depthPoints[i];
if(i == 0) println(currentPoint);
point(currentPoint.x, currentPoint.y, currentPoint.z );
}
}
您是否能够捕获红外流,但您就是看不到它?
那么问题可能是RANGE
(它应该在 [0, 255] 中)。
我在 Python 和 C++ 中遇到了这个问题;我通过将数组除以范围(最大-最小值)然后将所有条目乘以 255 来解决它。
user3550091是对的!作为参考,这是我的完整工作代码(Processing+OpenNI):
import SimpleOpenNI.*;
SimpleOpenNI context;
void setup(){
size(640 * 2 + 10, 480);
context = new SimpleOpenNI(this);
if(context.isInit() == false){
println("fail");
exit();
return;
}
context.enableDepth();
// enable ir generation
//context.enableIR(); old line
context.enableIR(1,1,1); //new line
background(200,0,0);
}
void draw(){
context.update();
image(context.depthImage(),context.depthWidth() + 10,0);
image(context.irImage(),0,0);
}
