Abstract

The present application discloses an image registration method, device and equipment, and a storage medium. The method includes: acquiring a real-time image and a predetermined standard image; respectively performing wavelet transformation on the real-time image and the standard image, and correspondingly obtaining the first An approximate component image and a second approximate component image; perform at least one geometric transformation on the first approximate component image, and calculate the mutual information between each transformed approximate component image and the second approximate component image; based on mutual The calculation result of the amount of information, and the maximum amount of mutual information is obtained as the registration result. By implementing the embodiment of the present application, while ensuring the accuracy of registration, the amount of computation when registering images can be reduced.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image registration method, device and equipment, and a storage medium. Background technique [0002] Ultrasonic (Ultrasonic, US) equipment is widely used in disease screening because of its advantages of no radiation and low price. When scanning the subject by ultrasonic equipment, the equipment operator usually places the probe of the ultrasonic equipment on the surface of the subject, and after the probe projects an ultrasonic beam in a certain direction to the subject, when the ultrasonic beam passes through the subject, The interface formed by the various tissues in the subject and the internal structure of each tissue can reflect or scatter the ultrasonic beam. The emitted or scattered ultrasonic beam is called an echo signal. Reflect the strength of the echo signal, and then arrange the light spots in an orderly manner to generate an ultrasonic im...
