Research And Application Of Imaging Tracking Technique In Developing Ophthalmological Equipment

This paper introduces imaging tracking technology, its hardware andalgorithms. Based on the technology, an application system used inophthalmological equipment is described. The main contents of the study areas following:(1) Image process model of the image tracking system has been designedand realized to meet the needs of ophthalmological equipment. As the highrunning speed and very large capacity of the system, targets of designing themodel are of stabilization of real time image processing circuit, imagetracking algorithms and its realization.(2) In the designing of hardware, a very high speed DSP chip of TIcompany is used to meet the speed needs of the image signal processing andsampling。The hardware is realized with the EDA technology. Double slotsRAM applying makes parallel data reading and writing, so helped the speedof data processing and exchanging.(3) In the aspect of algorithm designing and realizing, considering thebackground that the system is used for remote scenery, weak signal, aforecasting algorithm of wave gate tracking model is developed which can estimate next location of the object, so that tracking precision is good.By using the hardware and algorithm designing for entire image processmodel, the real time and intelligent properties of imaging tracking system aresatisfied, then it may be wildly used on practice.
