| Abstract: | According to the interlaced scanning of TV,a frame of image taken by ordinary TV camera can be divided to two fields one after another,through which a good transient flow map is obtained by using image processing method of minimum error matching to tracing particles.Using CCD and computer technology in college physics experiments is an initial research on the innovation of teaching content and method of instruction. |
