Embodiment Construction

[0039] The oblique photographic data includes oblique photographic model data and oblique photographic texture data.

[0040] The method and device for storing and scheduling oblique photography data according to the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] In order to improve the loading, scheduling and rendering speed of oblique photographic data, an embodiment of the present invention provides a method for storing oblique photographic data, so as to realize data storage of oblique photographic models. The method as figure 1 As shown, it specifically includes the following operations:

[0042] Step S101 , segment the oblique photographic model according to the tree structure at least according to the resolution of the oblique photographic model, and each level of the tree structure corresponds to a resolution.

[0043] Wherein, the resolution of the photo corresponding to the oblique phot...

Abstract

The present invention relates to the technical field of image data processing, and provides an oblique photograph data storage and scheduling method and apparatus. The oblique photograph data storage method comprises segmenting an oblique photograph model according to a tree structure at least according to resolutions of the oblique photograph model, each hierarchy of the tree structure being corresponding to one resolution; and saving each node model obtained by segmentation in a file form, a file of a father node module comprising indexes of sub-node modules thereof. According to the oblique photograph data storage and scheduling method and apparatus, loading, scheduling and rendering speeds of oblique photograph data are increased.

Description

technical field [0001] The invention relates to the technical field of image data processing, in particular to a method and device for storing and scheduling oblique photography data. Background technique [0002] With the popularity of drones, oblique photography has become a new high-tech developed in recent years. [0003] Oblique photography technology overturns the previous limitation that orthophoto images can only be taken from vertical angles. By carrying multiple sensors on the same flight platform, images are collected from different angles such as one vertical and multiple obliques at the same time, introducing users into The real intuitive world of vision. [0004] The acquisition of oblique photographic data becomes easier and easier, and a large amount of oblique photographic data is generated all the time. Accompanying it is the storage, loading, scheduling, and rendering of massive oblique photography data. [0005] Currently, the acquired oblique photogra...
