High-speed distributed camera network based on Message Passing Interface

High-speed camera can be implemented into a distributed camera network, which makes the camera network available to various dynamic applications such as observation at high speed and tracking of fast moving objects. This network system can be referred as high-speed distributed smart cameras (H-DSC). In order to construct a H-DSC, accurate synchronization between cameras as well as real-time feature of whole system should be carefully considered due to the restriction of `high speed'. In this paper, we describe a H-DSC system which has a simple structure based on Message Passing Interface and show that it has enough accuracy in time synchronization to use in dynamic applications. Image capturing at 400 Hz and object tracking at 200 Hz are shown as a kind of example tasks. It is expected that, of course, if we use higher frame rate cameras, our system structure also will work at higher speed such as 1,000 Hz.
