The invention discloses a fiber placement method based on a geodesic line between two points on a curve and relates to the field of composite material automatic fiber placement and molding. The method comprises the steps that the two points on the curve for fiber placement are selected, a point-to-point geodesic trajectory calculating algorithm is achieved by establishing a discrete mathematical model of a general free-form surface, the geodesic line between the two points of the curve for fiber placement is obtained, and then fiber placement is conducted along the trajectory of the geodesic line. The algorithm of the geodesic line between the two points on the curve is simplified, and the fiber placement efficiency is improved.
