Hey all.
It seems contourfinder in openCV is a little borked for me.
When I draw the contourfinder on the grayimage it lines up well but not on my kinect feed it seems to be about 20 px too high.
Any help woul dbe super appreciated.
void testApp::setup(){
ofBackground(204,204,204);
ofSetCircleResolution(100);
ofSetFrameRate(60);
//circle
myCircle.x = 100;
myCircle.y = 100;
myCircle.radius = 100;
//kinect
kinect.init();
kinect.open();
angle = 0;
//kinect.setCameraTiltAngle(angle);
//blob detection
colorImg.allocate(kinect.width, kinect.height);
grayImage.allocate(kinect.width, kinect.height);
grayThresh.allocate(kinect.width, kinect.height);
grayThreshFar.allocate(kinect.width, kinect.height);
nearThreshold = 230;
farThreshold = 150;
bThreshWithOpenCV = true;
}
//--------------------------------------------------------------
void testApp::update(){
//kinect
kinect.update();
//blob detection
if(kinect.isFrameNew()){
grayImage.setFromPixels(kinect.getDepthPixels(), kinect.width, kinect.height);
grayThreshFar = grayImage;
grayThresh = grayImage;
grayThresh.threshold(nearThreshold, true);
grayThreshFar.threshold(farThreshold);
cvAnd(grayThresh.getCvImage(), grayThreshFar.getCvImage(), grayImage.getCvImage(), NULL);
contourFinder.findContours(grayImage, 10, (kinect.width*kinect.height)/2, 20, false);
}
}
//--------------------------------------------------------------
void testApp::draw(){
//kinect
kinect.draw(0, 0, 1024, 768);
//kinect.drawDepth(0, 0, 1024, 768);
//blob detection
//grayImage.draw(0, 0, 1024, 768);
contourFinder.draw(0, 0, 1024, 768);
//circle
//myCircle.draw();
}
