Abstract
Image processing method and device are provided. The method includes: controlling a projector to project multi-stripe structured light and dot structured light onto an object, to form multiple light stripes and light spots between the light stripes on the surface of the object; acquiring a target image of the object having the light stripes and the light spots on the surface; obtaining a reference image including the light stripes and the light spots; calculating a first depth value at each light stripe in the target image based on feature information of the light stripes in the reference image and target image; calculating a second depth value at each light spot in the target image based on feature information of the light spots in the reference image and target image; and generating a depth image of the target image based on the first depth value and the second depth value.
