目前现场要处理的潜油电泵的电流卡片图像中有些图像位置布局不规则、有些图像边缘特征模糊、且所占的比例不小,这些现状给确定电流卡片的中心坐标造成很大的障碍,从而影响特征值的获取。由于目前还没有统一的方法来解决这问题,鉴于这种状况,对求取电流卡片中心坐标的方法进行研究讨论,提出了一种方法,并通过实例应用,获得了有意义的结论。 At present, some image positions in current card images of submersible pump to be dealt with are irregular in layout, some of the edges of image are fuzzy and their proportions are not small, and these present conditions cause great obstacles to determine the center coordinates of the current card, Thus affecting the acquisition of eigenvalues. In view of this situation, there is no unified method to solve this problem. In view of this situation, a method to get the current card center coordinates is discussed and discussed, and a method is put forward. Through the application of examples, meaningful conclusions are obtained.
