Abstract

The embodiment of the invention discloses a method for creating a three-dimensional dynamic scene. The method comprises the following steps: determining a three-dimensional mapping parameter of at least one image acquisition device by analyzing a historical dynamic image; according to the three-dimensional mapping parameters, mapping two-dimensional attribute information of a first object in a real-time dynamic image into three-dimensional attribute information, the historical dynamic image or the real-time dynamic image comprising a sequence image and / or a video image; adding the three-dimensional attribute information of the first object to a three-dimensional dynamic template; and rendering the three-dimensional dynamic template in real time to obtain a real-time three-dimensional dynamic scene. Compared with a three-dimensional static scene obtained through a traditional three-dimensional reconstruction method, information contained in the dynamic scene is more comprehensive and richer and can serve as a basis for analyzing dynamic object behaviors in the scene.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method for creating a three-dimensional dynamic scene, a method for analyzing behavior based on a three-dimensional scene, a data processing method, a corresponding device, a computer device, and a computer-readable storage medium . Background technique [0002] Compared with two-dimensional images, three-dimensional images can more accurately reflect the information of the real world. Therefore, it is of great significance to convert the more commonly collected two-dimensional images into three-dimensional images. [0003] At present, the method of 3D reconstruction is usually used to obtain 3D images. Specifically, it refers to obtaining data images of scene objects through cameras, analyzing and processing the images, and then combining computer vision knowledge to obtain 3D information of objects in the real environment. [0004] The applicant found in p...
