An ultrasound image processing method and device, an ultrasonic diagnosis device, and a computer-readable storage medium, relating to the field of image processing. The ultrasound image processing method comprises: acquiring an ultrasound image of an amniotic fluid pocket; identifying an amniotic fluid opaque area corresponding to the amniotic fluid pocket in the ultrasound image; and measuring the greatest vertical depth of the amniotic fluid pocket according to the greatest vertical depth of the amniotic fluid opaque area. The method and related device can avoid the impact of human factors on a measurement result of an amniotic fluid volume as far as possible and improve the accuracy of an amniotic fluid detection result, and are beneficial to reduction in misdiagnoses.
