PARTICLE TRACKING SYSTEM AND METHOD

Preferred embodiment systems of the invention use a scalable number of cameras that can image a volume of interest from plurality of angles. The volume can be large and illuminated with general non-coherent illumination. Synchronized cameras process data in real time to addresses particle overlap issues while also increasing observable volumes. Systems of the invention also use higher frame rate cameras to increase the amount of particle travel in each frame. Approaches of the invention alleviate the concerns with additional data accumulation by conducting image processing and segmentation at the time of acquisition prior to transfer from a camera to eliminate a data transfer bottleneck between camera and computer and eliminate a data storage problem. A heterogeneous CPU/GPU processor cluster processes data sent from the plurality of programmable, synchronized cameras and conducting multi-camera correspondence, 3D reconstruction, tracking and result visualization in real time by spreading processing over multiple CPUs and GPUs. Systems of the invention be scaled to hundreds of cameras and fully characterize fluid flows extending to room size and larger.
