Embodiment Construction

[0059]In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0060] Figure 1A A schematic diagram showing application scenarios according to some embodiments of the present application. Such as Figure 1A As shown, the application scenario includes a fisheye camera 110 , a video recorder 120 and a monitoring terminal 130 .

[0061] Such as Figure 1A As shown, the fisheye camera 110 can capture fisheye images. Here, the fisheye image may be a standard fisheye image or a curved fisheye image. A standard fisheye image means that the effective image area in the fisheye image is a complete circular area. The valid image area in a curved fisheye image is not a complete circular area. Compared with the effective image area of ​​the standard fish-eye image, the effective image area in the curved fish-eye image i...

Abstract

The invention provides an image processing method, a computing device, a system and a storage medium. Modeling convenience can be improved. The image processing method comprises the steps of determining a target area in a two-dimensional coordinate system, wherein the shape of the target area corresponds to the shape of an effective image area in a cambered fisheye image to be corrected; determining a hemispherical surface where a to-be-generated cambered surface model is located, wherein the to-be-generated cambered surface model is a three-dimensional model corresponding to the cambered surface fisheye image; and projecting a plurality of target points in a target area to the hemispherical surface to obtain a plurality of mapping points of the plurality of target points on the hemispherical surface, and taking the plurality of mapping points as vertexes of the cambered surface model.

Description

technical field [0001] The present application relates to the technical field of video surveillance, in particular to an image processing method, device, computing device and storage medium. Background technique [0002] At present, in application scenarios such as video surveillance, operations such as previewing fisheye images are required. In order to present the corrected image corresponding to the fisheye image, the image processing device first needs to establish a three-dimensional model corresponding to the fisheye image, for example, a hemisphere model. Taking the establishment of a hemisphere model as an example, the image processing device can generate a model composed of multiple vertices according to the given number of latitude lines and longitude lines. Then, the image processing device can further determine the texture coordinates corresponding to the vertices in the three-dimensional model. The texture coordinates are the coordinates of the target point in...
