The invention relates to a rapid depth map coding mode selection method based on an JNDD (Just Noticeable Depth Difference) model, and the method comprises the following steps of: carrying out edge detection on a coding macro-block to obtain an edge value of the current block; determining a threshold value which cannot be preceived by human eyes of a depth difference in different depth value regions in the macro-block by utilizing a minimum perceptible depth difference model, comparing the threshold value with the edge value, and dividing a depth map into a vertical edge region and a flat region; and adopting a full search strategy on the edge region, and adopting SKIP (Simple Key Internet Protocol) mode search, interframe 16*16 mode search and intraframe mode search on the flat region. By utilizing the rapid depth map coding mode selection method, according to the characteristics of depth data and influences of depth coding distortion on the drawing visual quality, on the premise of ensuring the virtual visual quality and the coding rate to be basically invariable, the coding complexity can be greatly lowered, and the coding speed of a depth map coding module in a three-dimensional video system is increased.
