Technology of Capturing Synchronization and Real-Time Processing in Twin Video
Tang Jian-bo · Optics & Optoelectronic Technology · 2009
Through the external HD/VD trigger synchronization of CCD,and combining the capture channel soft-switch as well as multithreading,event-driving,compressing display,the capturing synchronization,real-time processing and displaying of twin video are realized.In the algorithm of target pick-up,firstly,the disturbance is closed off by band block filter. Then,the star aim is distinguished from the background by automation threshold segmentation.At last,the decoy is eliminated by clustering,and the center-of-moment is calculated.Experimental results show that this technology can steadily pick-up star aim from twin video and fulfill real time capability based on single PC104.
