The application discloses a depth map creating method and system, and an image blurring method and system. The depth map creating method includes obtaining a first image and a second image obtained by shooting a target scene with a binocular shooting system; determining feature points corresponding to the images separately, thereby obtaining a first group of feature points and a second group of feature points; utilizing the first group of feature points and the second group of feature points to correspondingly determine supporting points corresponding to the images, thereby obtaining a first group of supporting points and a second group of supporting points; based on the first group of supporting points and the second group of supporting points, performing dense stereo matching on the first image and the second image to determine the parallax error between the first image and the second image; and utilizing the parallax to determine a depth map corresponding to the target scene.
