The Application And Study Of Image Inspection Technique In System Automatically Recorded Table-tennis Skills And Tactics

China national table-tennis achieve good grades which rooted in mass-based fan.It also attribute to work of large numbers of coaches and technology person. It is necessary to study about the games for average up.The paper proposes a new method How to obtain the placement on the table. The article adopts the technology of image process and computer's instrument to compute the coordinates of table comer. It will be appropriate for description of the track with the center computed with three-step search and precise match. This process could be modeled as two parabolic curves. The intersection would be seen as the placement in the image. Then it is feasible to transform the placement in the image into the placement on the table with Perspective Transformation. As a result, the method by this article accelerate the process make the traditional more unnecessary and not desirable.The paper proposes a new detection method which combines the hue threshold with contour in lowlight situations. It detects four corner joint of the table in the video with contour model.It scripts the trail of the ball in the games with fitting curves.We can regard the low-water mark as the placement of the ball. Then it models and sets coordinate axis for the placement of the ball to analysis the games.The paper is organized as follows. The background and situation of the study is projected at first. it emphasize on the situation Domestic and abroad. meantime, it simplify the system of techniques analysis of table-tennis.It introduce theoretical principle then.What is more.it describes the script language of the technique and tactics of table-tennis and translated the placement into the script language, which adopted by the system of techniques and tactics of table-tennis. Lastly, we test the system's function and performance.
