The invention discloses an automatic diaphragm movement degree measuring method and device and a storage medium. The method comprises the following steps: acquiring an M-mode diaphragm ultrasonic image which is not less than one complete respiratory cycle in an M mode; segmenting the M-mode diaphragm ultrasound image through a first convolutional neural network model to obtain a diaphragm mask; according to the diaphragm mask, the positions of the end expiration and the end inspiration are obtained through calculation, and according to the positions of the end expiration and the end inspiration, the movement degree of the diaphragm in the inspiration and expiration processes is obtained through calculation. According to the embodiment of the invention, the diaphragm region can be accurately segmented, and then the positions of the inspiratory end and the expiratory end of the diaphragm are calculated, so that the diaphragm movement degree is effectively measured. The diaphragm region can be automatically segm
