I am a beginner in matlab, I have purchased Computer Vision System Toolbox. I have being given 400 of depth images (.PNG images). I would like to create a point cloud for each image. I looked at the documentation of Computer Vision System Toolbox, and there is an example of converting depth image to point cloud (http://uk.mathworks.com/help/vision/ref/depthtopointcloud.html):
[xyzPoints,flippedDepthImage] = depthToPointCloud(depthImage,depthDevice)
depthDevice = imaq.VideoDevice('kinect',2)
but the thing that I don't understand is that it requires Kinect camera and connection. I am not connecting to Kinect, I don't have Kinect, I am just given the output of Kinect which are the depth images.
how to make use of the function(depthToPointCloud) in the toolbox in generating cloud points from already given depth images without connecting to Kinect camera?
Unfortunately, the depthToPointCloud function only works with Kinect v1, and it requires a connection to the Kinect to get the camera parameters.
