Abstract

The embodiment of the invention discloses a coordinate determination method and device for a position point in an image, equipment and a storage medium, and the method comprises the steps: determining a target point in a target image, and enabling the target image to be obtained through geometric transformation of an initial image; distributing a target identifier to the target point; and performing inverse transformation of the geometric transformation on the target image to obtain a restored initial image, and determining a target point coordinate of the target point in the restored initial image according to the target identifier. According to the scheme, rapid and efficient positioning of the position points is realized, and meanwhile, coordinate errors caused by coordinate transformation are reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular to a method, device, device, and storage medium for determining the coordinates of a position point in an image. Background technique [0002] With the development of image processing technology, it is applied to more and more scenes. In the process of image processing, the global or local geometric transformation of the image is widely used as an important part of image processing technology. Such as shrinking the image in the convolutional neural network model, or the local geometric transformation that needs to be used in the process of solving the image coordinates. [0003] In the prior art, when the geometric transformation of the image is performed, since the position points undergo coordinate conversion, it will be difficult to locate the original position points that have a corresponding relationship. Come coordinate error, need to...
