Abstract: A high-definition map building method includes determining a key node describing information about a key position of a lane attribute change, determining a key node layer based on a position of the key node and an attribute of the key node, and determining a high-definition map based on a navigation map and the key node layer. The navigation map provides road-level navigation information, and the high-definition map provides lane-level navigation information.

Abstract: This application provides a flexible screen cover. The flexible screen cover includes a protective layer, a main layer, and a buffer layer. A modulus ratio of the main layer to the buffer layer is 8 to 180000. The buffer layer can be disposed at any proper position in the flexible screen. A modulus ratio of an adjacent layer to a buffer layer is 2 to 500000. The collapsible electronic device includes a housing and a flexible screen, and the flexible screen is installed in the housing. This application can improve impact resistance performance of the flexible screen.
