Abstract: A panorama rendering method, an electronic device and a storage medium are provided, and relates to the field of panoramic technology. The method includes: segmenting a panoramic picture to obtain segmented panoramic tile pictures; determining a target tile picture under a current screen and a target spherical patch in a panoramic picture sphere model, according to the panoramic picture sphere model and the segmented panoramic tile pictures; and pelfonning drawing on the target spherical patch by using the target tile picture, to obtain a target scene. In this way, time consumption of panorama loading can be reduced and loading performance can be improved.

Abstract: This application discloses a map display method and apparatus, where the method includes: obtaining an initial image, where a first road is included in the initial image. The initial image is divided into a first sub-image and a second sub-image, where the first road is not included in the first sub-image, and the first road is included in the second sub-image. The first sub-image is mapped to a first plane of a transition model, and the second sub-image is mapped to a second plane of the transition model, where there is an included angle between the first plane and the second plane, and the first plane is parallel to a screen of a display device. The second plane is controlled to move by means of the transition model, until the included angle is reduced from a first angle to a second angle, and a three-dimensional map display animation is obtained.

Abstract: A map displaying method, an electronic device, a storage medium and a terminal device are provided, and relate to the technical fields of computer vision and intelligent transportation. The method includes: receiving a trigger operation in a case that a terminal device displays a map of a first area, and determining a screen coordinate of the trigger point, where the map of the first area is a map where a first position is at a center area; determining a coordinate of a ground projection point corresponding to the trigger point based on the screen coordinate of the trigger point; switching a currently displayed map of the first area to a map of a second area, in a case that the ground projection point falls within the first area, wherein the map of the second area is a map where the ground projection point is at a center area.
