DEPTH MAP GENERATION METHOD USING PREVIOUS FRAME INFORMATION FOR FAST DEPTH ESTIMATION

Abstract: provided is a depth map generation method using previous frame information. a depth map generation method according to an embodiment of the disclosure extracts a feature map of a 1/n scale resolution on a stereo image of a current frame, and generates a depth map of a 1/n scale resolution of the current frame by using a depth map of a 1/n scale resolution on a stereo image of a previous frame, and the extracted feature map. accordingly, a depth map of a current frame is generated by using a depth map of a previous frame based on continuity of information between continuous frames of a moving image, so that efficient use of resources, reduction of a calculation response time, enhancement of accuracy are possible.
