A method for modeling background and foreground extraction depth map based on

The present invention relates to a method based on an image and depth map background modeling the extracted foreground, characterized by comprising: a step of obtaining a depth image characterizing the object distance from the camera; step two, the depth of the background model in real time initialization; Step three, the update real-time depth background model; step 4 acquires characterization of the object from the current depth image of the camera distance; step five, the real-time depth background model extracts the current depth image foreground image based; step 6 outputs the foreground image, generating real-time target mask of FIG; step seven background model updated in real depth: the real-time target mask pattern, the code group information updated in real time the depth of each pixel in the background model of the present invention using the color map has a known modeling method unmatched stability, high efficiency and the processing advantages of the positional relationship, and does not require an initial model of the scene, simplifies the implementation step, the overall performance is greatly improved.
