I change them on arrows keystrokes by 1 pixel and then call copy_images and render the result. If you notice I added ofsx,ofsy variables to copy_images(). You need to add the OpenGL initialization and camera settings etc of coarse. I use OpenGL for this so here the code: glBegin(GL_QUADS) įor (int y0=0,y1=1 y1z) z0=z if (z1z) z0=z if (z1z) z0=z if (z1=3.90) continue // 3.972 pre vsetko nad.

The bigger in size the more accurate the result. So find some measurable feature visible on both images. So my results are affected by all this negatively. Also as I do not have the depths (depth image is 8bit only due to grayscale RGB) then the depth accuracy I work with is very poor see: This could cause minor offset change by few pixels. I manually crop your input image so I separate colors and depth images (as my program need them separated.
Matlab r2015a camera calibration kinect code#
The matlab code is illustrated below : I = imread('1.jpg') The ground truth which basically means the bounding boxes which specify the face region of interest are already provided and I use them to crop the face regions only. The dataset I am referring to is given in rgb-d-t face dataset. I was also suggested to use EPIPOLAR GEOMETRY to match the two images though I do not know how. Please note that I have checked several places for this - like here, here which requires a kinect device, and here here which says that camera parameters are required for calibration. It is better to close the kinect emitter have an IR projector/emitter that does not emit a pattern but emit clear IR rays so that the image obtained at the receiver is clean.I am trying to allign two images - one rgb and another depth using MATLAB.

To have this transformation For this it is necessary to get the internal characteristics of both the IR and RGB camera. In short, the output of this calibration will be an RGB-D image, or the Image will be an overlap of RGB and Depth Streams.

This can also be said as Kinect Stereo Calibration as we are calibrating two camera against each other. Thus getting into the topic, kinect calibration literary means to get a transformation between the co-ordinates of depth camera and RGB camera. Working of IR camera pair has been discussed and explained in detail in lot of posts by others and also by me. Kincet has an IR camera pair and an RGB camera. this post will introduce you to the world of calibrating the kinect. After looking at camera calibration and stereo calibration theoretically.
