Research Of The Terminal Timer System Based On Color CCD

In sport games, confirming the scores by former handicraft can't satisfy the request. According to the provision of the IAAF (International Amateur Athletic Federation), all the large athletics expositions request to adopt the electric terminal timer system. At present, the studying level in our country is still staying around the black and white. The electric timer equipments for our games are primarily made abroad. The price of the abroad product is very expensive, so it is not suitable for the extensive usage. The paper applies the super-speed color linear CCD array technique to terminal timer system, and manufactures our colorful track terminal timer system. This is the demand of our market as well as the development of our athletics business.This paper states the constituting parts and their functions of the electric terminal timer system, and sets forth the working principle of the system. Through the introduction of the electric charge saving and the introduction of the infusing method with the signal of CCD, the paper expatiates the CCD working principle. The article also studies the influences that are caused by CCD functional parameter to the CCD deferent signal. Picture signal at collecting and delivering process would be damaged and get weak. Therefore, the article manages digital image processing techniques such as the filtering, colorful equilibrium, histogram equalization and so on, so that we can get image with clear and high quantity. Finally, the article analyzes the movement of the system software, expatiates the concrete operating method of the whole process from the information kinescoping to the decision and the print, as well as the final timer and the alignment of the position.The paper proceeds the thorough analysis for every kind of factor which affects the picture quantity in the process of CCD collecting image, and from the hardware aspect, puts forward to restrain the noise interference through related double kinds electric circuit, increasing the ratio of the signal and the noise; while from the software aspect, improves the manifestation result through the digital...
