16-bit image to 32-bit

I am loading an image that is .png, which is 16-bit with 1 channel (depth image from Kinect Sensor). I want to convert it to an image with 3 channels (color) and 32-bit.

How do I do this ?

Step 1: 16 --> 32 bits

cv::Mat depthImage:
cv::Mat depth32;
float scaleFactor = 1.0; // Or what you want
depthImage.convertTo(depth32, CV_32F, scaleFactor);

Step 2: 1 ---> 3 channels

#include <opencv2/imgproc/imgproc.hpp>
cv::Mat depthColor32;
cv::cvtColor(depth32, depthColor32, CV_GRAY2BGR);

And that's it.
