摘要： 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.

摘要： The invention provides a method and electronic device for a mapping table in a solid-state memory, wherein the mapping table comprises a primary mapping table and a secondary mapping table. The method comprises: mapping all logic pages from a host to physical pages of a flash on the solid-state memory in the unit of page to form the secondary mapping table, the secondary mapping table being stored in the flash on the solid-state memory; acquiring a first physical address which is the physical address of a first chunk of the secondary mapping table in the flash of the solid-state memory; and forming and storing the primary mapping table in the flash of the solid-state memory, wherein the first physical address and corresponding first identifying information form a mapping relationship in a mapping element of the primary mapping table, the first identifying information being identifying information of the first chunk.
