Kinect Depth Threshold

Hi Everyone,

Im trying to use the Kinect Depth Image to create a distance threshold, so all pixels within say 5ft are white ,any beyond that are black.

I am fairly new to processing but i think i need to use an array and a for loop but Im struggling a bit to make it work.

Could anyone possible post me an example for me too look over and learn from?

Regards,

Oli.

Hi again,

would you mind looking at my code if you get chance,

I have tried to amend your code so it just uses the depth images;

I want to set a threshold that sets the pixels either black or white but Im getting a problem with my for loop.

Any input would be great!

Regards,

Oli

//kinect interface

import SimpleOpenNI.*;

SimpleOpenNI kinect;

// kinect depth values

int[] depthValues;

int thresh = 1500; //sets the depths threshold

int kinectImageSize = 640 *480;

void setup() {

size(640, 480);

kinect = new SimpleOpenNI(this);

kinect.enableDepth();

}

void draw() {

kinect.update();

PImage depthImage = kinect.depthImage();

image(depthImage, 0, 0);

for (int pic = 0; pic < kinectImageSize; pic++)

{

if (depthValues[pic] > thresh)

depthValues[pic] = color(255);

else

depthValues[pic] = color(0);

}
