Kinect mapping color image to depth image in MATLAB

Question

I have collected data using Kinect v2 sensor and I have a depth map together with its corresponding RGB image. I also calibrated the sensor and obtained the rotation and tra

Answer 1

The Image Acquisition Toolbox now officially supports Kinect v2 for Windows. You can get a point cloud out from Kinect using pcfromkinect function in the Computer Vision System Toolbox.

Answer 2

Why can't you fit the Z-depth to the RGB?

To fit the low res image to the high- res should be easy, as long as both represent the same size of data (i.e. corners of both images are the same point)

It should be as easy as:

Z_interp=imresize(Zimg, [size(RGB,1) size(RGB,2)])

Now Z_interp should have the same amount of pixels as RGB

If you still want to do it the other way around, well, use the same approach:

RGB_interp=imresize(RGB, [size(Zimg,1) size(Zimg,2)])
