Embodiment
[0033] This embodiment provides a method for generating a labor navigation curve, which is characterized in that it includes the following steps:
[0034] (A1) Obtain the coordinates of the upper edge of the pubic symphysis and the lower edge of the pubic symphysis on the ultrasound image;
[0035] (A2) Calculate the coordinates of the guide point on the ultrasound image in sequence according to the predicted constraint relationship;
[0036] (A3) Connecting the guide points sequentially on the ultrasound scanning plane to generate a labor process navigation curve.
[0037] As a preferred embodiment of the present invention, the predictive constraint relationship is: the three interior angles of the triangle formed by the upper edge of the pubic symphysis, the lower edge of the pubic symphysis and any one of the guide points on the ultrasonic scanning plane are predictable;
[0038] According to the predicted constraint relationship, the step of calculating the coordinates of...
