Real time, high speed position tracking

We measured a fly's position in real time at 1000Hz using our TrackFast technology. The original position of the camera's dynamic region of interest (dROI) was determined from the position data transferred by TrackFly. Each subimage was analyzed in real time and the fly's measured 2D (horizontal and vertical) position used to update the dROI for the subsequent frame. A calibration was used to convert from pixel coordinates to 2D real world coordinates. The subsequent video was produced by pasting the subimages corresponding to the dROI of each respective frame at the appropriate image location - at no time was the entire frame imaged as a whole!
