Abstract

The embodiment of the invention discloses a method, a device, a storage medium, and a terminal device for generating an elevation view of an object, which are applied in the technical field of information processing. The device for generating the elevation of the object will first roughly extract the point cloud data of the object surface from the point cloud data of the object, and then accurately obtain the reference surface equation where the surface of the object is located by means of plane fitting, and Remove the point cloud data of the point cloud data on the surface of the object that is not on the reference surface and the point cloud data that is beyond the preset range from the reference surface, and then consider the protruding objects on the surface of the object object, and project the point cloud data that is within the preset range from the reference surface Go to the reference surface, get all the point cloud data of the reference surface, and then render the elevation view of the object object according to all the point cloud data of the reference surface. In this way, the three-dimensional object attached to the surface of the object is considered, so that the elevation view of the object can reflect the actual object more finely.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a method and device for generating an elevation view of an object, a storage medium, and a terminal device. Background technique [0002] Whether a building is beautiful or not depends to a large extent on its artistic treatment on the main facade, including whether the shape and decoration are beautiful, and by collecting actual pictures of the building, the building elevation can be obtained, and the building facade The picture is the orthographic projection of the building on the projection plane parallel to the facade of the building, that is, the picture of the external wall of the building, such as a picture reflecting the geometric relationship between the doors, windows and balconies of the building, etc., which can be applied to various application fields, such as game scenes in the field of modeling. [0003] A building facade extraction method b...
