Abstract: In the method, a terminal device display a first interface including a taken picture; collect a plurality of frames of images corresponding target object, and obtain an association relationship between the plurality of frames of images; and obtain a three-dimensional model corresponding to the target object based on the plurality of frames of images and the association relationship between the plurality of frames of images, and display the three-dimensional model. When the plurality of frames of images are collected, a first virtual bounding body including a plurality of patches is displayed. When the terminal device is in a first pose, the terminal device collects a first image, and changes a display effect of a patch corresponding to the first image. When the terminal device is in a second pose, the terminal device collects a second image, and changes a display effect of a patch corresponding to the second image.

Abstract: Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition a quinone methide polymerization retarder and an oxygen-containing amine compound that is a tertiary amine or hydroxylamine. In a mixture, the oxygen-containing amine compound improves the efficacy of the quinone methide polymerization retarder and provides greater antipolymerant activity. In turn, the mixture reduces or prevents apparatus fouling and improves the purity of monomer streams.
