Embodiment 1

[0070] The above is the first embodiment of the image rendering method provided by the embodiment of the present application, and the following is the second embodiment of the image rendering method provided by the embodiment of the present application.

[0071] see figure 2 , a schematic flowchart of Embodiment 2 of an image rendering method in the embodiment of the present application.

[0072] A picture rendering method in this embodiment includes:

[0073] Step 201, real-time detection of the current canvas range of the rendering canvas at the current moment.

[0074] In this embodiment, the image rendering request is obtained by changing the current canvas range of the rendering canvas. Therefore, in this embodiment, the current canvas range of the rendering canvas at the current moment is detected in real time.

[0075] It should be noted that the range of the current canvas can be changed by panning the rendering canvas or zooming the rendering canvas. The zoom oper...

Abstract

The invention discloses a picture rendering method, apparatus and device, and a storage medium. The method comprises the steps of obtaining a picture rendering request; in response to the picture rendering request, obtaining a target to-be-rendered picture; dynamically loading a thumbnail of the target to-be-rendered picture and rendering data for rendering in a rendering canvas for rendering based on picture information of the target to-be-rendered picture, the thumbnail being obtained by compressing the target to-be-rendered picture according to a preset compression ratio; and rendering thethumbnail in the rendering canvas according to the rendering data. The technical problems of low loading speed, long consumed time, rendering display lag and insufficient memory caused by overlarge data volume are solved.

Description

technical field [0001] The present application relates to the technical field of image rendering, and in particular to an image rendering method, device, device and storage medium. Background technique [0002] With the development of science and technology, the application of drones is becoming more and more diverse. As a kind of UAV application, UAV aerial survey is a powerful supplement to traditional aerial photogrammetry. And flying difficult areas have obvious advantages. [0003] When using drones for aerial surveys, thousands or even tens of thousands of high-resolution (6000*4000) pictures are taken to build tilt models. Before constructing the oblique model through these images, it is necessary to perform rendering processing first. However, in the process of rendering processing, it will take a long time to load all the images, and with the existing commonly used computer memory, it may be difficult to read the above images. There will be memory exhaustion caus...
