IPingPong description - image acquisition
The IPingPong interface implements an asynchronous image acquisition with two buffers.
All functions of this interface are also used by the CV Image Control if you start an acquisition by setting its Grab property to TRUE.
In CVB, this can be implemented via the PingPong functions of the CVB Driver Library or the Grab property and Snap method of the CV Image Control.
•Two buffers are used in Ping Pong mode.
•No frames are lost as long as processing keeps up with camera frame rate.
A description of these interfaces can be found in the Common Vision Blox Manual.
For testing purposes, please use the CVB Image Manager Tutorials VB.Net Ping Pong example or the VCPureDLL/VCDriverMDI example (menu Edit-PingPong Grab) or any other CVB Tutorial program .
Modern image acquisition devices can support more than 2 buffers using the IGrab2 interface.
All functions of this interface are also used by the CV Image Control if you start an acquisition by setting its Grab property to TRUE.
