| Abstract: | This paper is mainly focused on the method of realtime datum acquisition and its processing with the aid of CCD cameras and computer software,which is used to process the value of the excursion of the subsidiary image of safety glazing materials used on road vehicles.Firstly,CCD and image collecting board are used to transform the optical images of the excursion of subsidiary image into the datum patterns recognizable by computers.Then,the value of the excursion of subsidiary image can be got by the image processing programme.This method has the advantages of high measuring precision,real time display of result and measureability in the condition of interior illumination. |
