I am planning on using a device such as the Microsoft Kinect or an Asus Xtion Pro for 3D imaging purposes and they are great on all specs except for the minimum range. Is there anyway to make the range shorter, either through software modifications, or is there any similar hardware with a closer minimum range?
The only option I have found is this: http://nyko.com/products/product-detail/?name=Zoom which adds an element of distortion though does reduce the minimum depth by up to 40%.
