A method for removing the noise of a sparse depth map according to the present invention includes the steps of : setting sampling points on the sparse depth map including depth information at a partial position on an image plane as nodes, respectively; connecting the set nodes to be meshed; and removing the noise of the meshed node based on connection information of the meshed node and the neighboring node and color information of a color image corresponding to the sparse depth map. A depth value is assigned to each of the sample points. Accordingly, the present invention can more accurately remove the noise of the sparse depth map while maintaining the clarity of a depth continuous section and a depth discontinuous section.(AA) Start(BB) End(S110) Setting sampling points on a sparse depth map as nodes to be meshed(S120) Removing the noise based on connection information of the node and color information of a color image(S130) Removing the noise based on a plane modelCOPYRIGHT KIPO 2018
