Abstract: An image processing method, an electronic device and a non-transitory computer-readable storage medium are provided. The image processing method includes: obtaining a first grayscale value corresponding to each pixel in a first image and a second grayscale value corresponding to each pixel in a second image; and determining a compensation parameter according to the first grayscale value and the second grayscale value corresponding to each pixel. The compensation parameter is used for compensating for an image generated by augmented reality glasses. The first image is an image generated by the augmented reality glasses. The second image is an output image of the augmented reality glasses.

Abstract: Provided are a method for preparing a gel composite material with a piezoelectric property, and the gel composite material and use thereof, which belongs to the field of intelligent road traffic. In the method, titanium-containing blast furnace slag and metal oxides (PbO and ZrO2) are sufficiently and uniformly mixed, an obtained mixture is calcined under a certain thermal system, on the theoretical basis of mineral-phase reconstruction-synergistic regulation of all valuable components, and the mixture is cooled to a room temperature with a furnace to obtain the gel composite material with a piezoelectric property.

Abstract: An arc surface milling machine includes a worktable, a base and a backup plate. The worktable is assembled adjacent to the base. The backup plate is adjustably mounted on the base and positioned adjacent to the worktable. The worktable includes a work surface, an opposite bottom surface, and a mounting end. The base is assembled to the mounting end of the worktable. The work surface defines a concave wedge-shaped receiving space adjacent to the mounting end and forms a milling opening communicating with the work surface and the mounting end.
