Method and apparatus for recognizing intelligently ultrasound womb contraceptive ring image

A ultrasonic womb contraceptive ring image intelligent identifying method is provided in the present invention, comprising the following steps: a, collecting ultrasonic womb image by B-ultrasonic equipment; b, processing to eliminate noise and gray scale linear intercept to the original womb image; c, processing to fixed threshold value separate and morphology treatment to processed womb image, through region extraction to acquire a plurality of candidate object like contraceptive ring; d, extracting the characteristic value of the candidate object, using contraceptive ring image data parameter base and multi-classifying fusion structure identifying system to process intelligent identification to the acquired candidate object, judging whether there is contraceptive ring object in the ultrasonic womb image. The present invention also provides an equipment used by the method. The present invention can effectively be used for assisting ultrasonic ring-checking member to operation, promote the accuracy of ring-checking examination.
