A method of determining obstacle collision by using an object moving path includes: acquiring a topological skeleton corresponding to a path area on an image including a moving path of an object and an obstacle; determining, from among skeleton points forming the topological skeleton, branch points that are interconnecting points between branches of the topological skeleton; determining a target branch from among the branches by using the branch points; selecting, from among points forming the target branch, a plurality of target points to determine whether the moving path is a collision path of the object; and determining whether the moving path is the collision path by using the target points.
