" segmented error" Please be exact when talking about errors. It's probably an Segmentation Fault.

There several issues with your code: Using constants like '479' in your code is extremely(!) bad style. A pointcloud has width and height so use these variables. If you want to store a cloud with width of 480, you should also create an array with this size and not one if an entry less (479 instead of 480). (Why do you copy the pointcloud at all in this 2d array?)

But in general: What do you want to do?
