The invention provides an image segmentation based error concealment method for entire right frame loss in a stereoscopic video, and belongs to the field of video image processing. The method comprises the following steps: dividing a loss frame into a background region and a movement region by taking a macro block as a unit, reversely projecting a movement vector to adjust region division, finding a pixel from a left view point t-1 moment frame, wherein the pixel is corresponding to a pixel in a right view point t-1 moment frame, and adaptively concealing a macro block of a foreground region and filling up holes in different modes. The image segmentation based error concealment method for the entire right frame loss in the stereoscopic video, provided by the invention, can be used for accurately segmenting the foreground and the background of the image at lower computation complexity, and concealing the background, a movement complex region and a movement rule region by using different methods, and has a wide
