AI Technical Summary

Benefits of technology

The technology described in this patented describes how an imagery system captures 3D simulations with cameras attached thereto for creative purposes such as displaying or simulating objects within the scenes. By collectively determining colors from all points around every corner of these images, we get a virtual reality representation called a "virtual distorted". This allows us to generate customized visual experiences similar to what would have happened if there were no physical world inside during our experimentation. Additionally, the generated virtual distracted images look like they should appear looking normal but actually show up some slight deformation caused by imperfections in the optics lens (lenses). Overall, this technology helps make better understanding about complex systems involving multiple components interact through their interactions between light waves.

Problems solved by technology

The technical problem addressed in this patented method for improving how well an artificially creating or simulating environment looks like on its own screen during video capturing sessions involves adding distortations caused by different cameras with varying shapes such as curved surfaces or optical elements (lenses). This results in degradation of edges and loss of detail within the resulting image.

Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art based on the present application belong to the protection scope of the present invention.

[0070] In the related art, the generation method of the virtual distorted image is as follows: first obtain the non-distorted image collected by the virtual camera, and then determine the corresponding distortion parameters according to the preset distortion requirements, and use the distortion parameters to process the non-distorted image Affine transformation, to obtain a distorted image, that is, to obtain a virtual distorted image. However, in the above rela

Abstract

Embodiments of the invention provide a virtual distortion image generation method and device, and relates to the technical field of virtual reality. The method comprises the following steps: determining a to-be-rendered color parameter of each pixel point in an image plane of a virtual camera, wherein the to-be-rendered color parameter is obtained by mapping each virtual object in a three-dimensional simulation scene into an image plane under the condition that camera distortion does not exist; determining a distortion pixel point corresponding to each pixel point in the image plane based on a distortion parameter corresponding to a camera distortion type; and rendering the color parameter of each pixel point into the to-be-rendered color parameter of the distorted pixel point corresponding to each pixel point to obtain the virtual distortion image. Compared with the prior art, by applying the scheme provided by the embodiment of the invention, pixel loss in the virtual distortion image can be avoided, and image quality is improved.
