Research On Vectoring Method Of Premagnetic Curve

The vector of the Premagnetic curve will be conducive to the data storage, management, analysis, sharing and network transmission.This article do the Research on Premagnetic curve vector in funding of Daqing Oil Production Plant NO.2, on the basis of analysis about Premagnetic curve's characteristics,we proposed a new method of Premagnetic curve . This method first carries on the essential pretreatment to the blueprint, then compress image data, at last track course.According to the demand, this article has mainly realized four aspect pretreatment functions: the assistance function, the image intensification, the fog and the image partial pretreatment. The assistance function mainly does some auxiliary work, like cutting, penning, opposition, revolving and so on.To enhance the contrast of the blueprint,we developed the image intensification,and proposed a new method of histogram equalizing which can enhance the contrast of the blueprint very much.The pretreatment of fog can make some thin curse more thicker.In view of the curse are different to each other,we propsed the method of multi-threshold, each curve corresponds a division threshold value, so it can satisfied the division of each curve.Before track the curve,we compress the image ,and save the data after the division of the image with the LAG structure.There are three steps in the tracking part,first,we get the LAG data,second,make the LAG nodes to section which are Independent to each other,third, make the sections to the curve according to certain condition.This article has finally completed a system, which had many pretreatment functions, the result of tracking is good, obtained user's affirmation.
