Is there an easy way to calculate this scale factor in opencv?

Thanks for helping getting me started. So using this source code, it does compile and run but I think there is still an issue with the conversion.

cv::Mat(ir->height, ir->width, CV_32FC1, ir->data).copyTo(irmat);
irmat.convertTo(irmat, CV_8U, 1, 0); 
resize(irmat, irmat, cvSize(1920, 1080); 
cv::Mat(depth->height, depth->width, CV_32FC1, depth->data).copyTo(depthmat);
cv::Mat(rgb->height, rgb->width, CV_8UC4, rgb->data).copyTo(rgbmat, irmat);

When running this program, the IR image and the depth image when doing something similar don't match up properly to the rgb image.

I'm passing the RGB, Depth and IR image through from libfreenect2 to opencv, and I am having trouble working out how to use the the IR image as a mask over the RGB image to remove everything except humans from a video stream.

I've gotten the images from libfreenect2 and converted them to the following image types (based off this post) :

    cv::Mat(rgb->height, rgb->width, CV_8UC4, rgb->data).copyTo(rgbmat);
    cv::Mat(ir->height, ir->width, CV_32FC1, ir->data).copyTo(irmat);
    cv::Mat(depth->height, depth->width, CV_32FC1, depth->data).copyTo(depthmat);

Thanks in advance!
