A path planning method applied to a navigation device includes acquiring a two-dimensional depth map, transforming the two-dimensional depth map into a gray distribution map via statistics of pixel values on the two-dimensional depth map, computing a space matching map by arranging pixel counts on the gray distribution map, and computing a weighting value about each angle range of the space matching map in accordance with a distance from location of a pixel count to a reference point of the space matching map. The weighting value represents existential probability of an obstacle within the said angle range and a probable distance between the navigation device and the obstacle.
