3d Point Cloud Training in CNN

I have 3d point cloud dataset and I want to train with Convolutional Neural Network

</matlabcentral/answers/uploaded_files/68425/architecture.PNG> I must do model d architecture But How?

 I found some examples but all examples for prepared dataset like CIFAR,Imagenet

[Name]

I mean how can I create my CNN and how can I train my dataset not prepared

As of release R2016b, imageInputLayer of CNN feature in Neural Network Toolbox does not accept 3D images(volume data) or 3D point clouds, but just grayscale or RGB. If you want to apply CNN to 3D point clouds in MATLAB, you'll need to project your point clouds into 2D plane as images using a virtual camera with various angles. pcshow and getframe might be helpful for generating the training images.
