Method and Device for Determining Motion Trajectory of Target Subject, and Storage Medium

A device for determining a motion trajectory of a target object, comprising:

• one or more processors and a storage medium in which operation instructions are stored, wherein when the operation instructions stored in the storage medium are executed, the one or more processors perform steps of:
• acquiring a first control point and a second control point on a motion track based on a current position of the target object on the motion track, wherein the first control point and the second control point are adjacent control points;
• acquiring a first direction vector and a second direction vector, wherein the first direction vector is a unit direction vector at the first control point, and the second direction vector is a unit direction vector at the second control point;
• and
• determining the motion trajectory of the target object on the motion track through a specified spline curve interpolation model based on the first control point, the second control point, the first direction vector and the second direction vector.

A non-instantaneous computer readable storage medium, storing computer executable instructions, wherein when the executable instructions are executed in a computer, the computer performs:

• acquiring a first control point and a second control point on a motion track based on a current position of a target object on the motion track, wherein the first control point and the second control point are adjacent control points;
• acquiring a first direction vector and a second direction vector, wherein the first direction vector is a unit direction vector at the first control point, and the second direction vector is a unit direction vector at the second control point;
• and
• determining a motion trajectory of the target object on the motion track through a specified spline curve interpolation model based on the first control point, the second control point, the first direction vector and the second direction vector.
