| dc.description.abstract | As to the development of automation of the factory at present, the use of the vision technology of the machine can be regarded as an important development main strain. Machine Vision has been applied to industrial in many conditions, for example measurement measuring of the products , the homework of packing of product , LED light spot are measured , the robot welds work and two-dimentional bar code of products. If the above-mentioned examples come by way of tradition and finish, the vision of the machine occupies accuracy high, work security for a long time, building constructing and maintaining the advantage with low costs and studying the speed fast etc. with quick speed of production. In fact its application in the industrial automation is combined not only herein, so a thesis fetches one of them to carry on research, there are a lot of methods of distinguishing that the number distinguishes on the academic research. The purpose of this research is to probe into and utilize the statistic law of the area of image and this two methods of projection law of the image , the ones that raised numbers to debate and know debates the knowing rate and offers numbers to debate one yard of methods . On the other hand, we utilize automation equipment to orient the advantage of perfect and stability with high degree, calculate that the work piece moves the speed and makes the image in correct time and position, via the procedure reads and deal with Sobel leadingly after straining waves and removing image noise, use the line to scan the method and calculate and count the area of style of calligraphy and characteristic of style of calligraphy, and then explain for out the style of calligraphy of the image correctly. For let research this for correspond to reality homework situation even more , is it use automation in factory is it carve plane , industrial steel mould of script to play already to adopt we, cooperate with CCD image to pick and fetch the systematic homework environment of simulation factory, in order to reach the real result, expect to achieve the purpose that can be applied to automation of the factory, hope to make use of and offer by this research and distinguish another kind of different thinking directions of the respect with the general thesis in the number too. | en_US |
