Problems solved by technology

However, the Hough transform and its generalizations are less effective at detecting general curves
[0004] In practical applications, the detection of ordinary curves with a certain degree of curvature along the horizontal direction or other directions will be encountered. In this case, the detection effect of Hough transform and its extension is relatively poor, and the efficiency is low

Embodiment Construction

[0076] The present invention will be further described in detail below in conjunction with the embodiments of the accompanying drawings.

[0077] figure 1 A schematic flow chart of a curve detection method provided in the embodiment of the present application, the method includes:

[0078] S101: Perform binarization processing on the image to be detected to obtain a binarized image.

[0079] Those skilled in the art can use various methods to perform binarization processing on the image to be detected, including common image processing processes such as denoising, blurring, sharpening, binarization, dilation, and erosion, which will not be described in detail here. After the binarization process, the obtained binarized image only includes pixels of black and white pixel types. Exemplarily, black pixels represent background information, white pixels represent foreground information, and the curve to be detected is hidden in the foreground information.

[0080] Preferably, in...

Abstract

The invention discloses a curve detection method and device, equipment and a medium, and the method comprises the steps: carrying out the binarization of a to-be-detected image, and obtaining a binarized image; carrying out straight line detection on the binarized image to obtain a basic straight line; and expanding the basic straight line to obtain a curve point set where the basic straight lineis located.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a curve detection method, device, equipment and medium. Background technique [0002] In the process of image recognition and understanding, detecting the shape of objects in an image is of great significance. Among them, geometric curve detection has been widely used in technical fields such as object recognition, object tracking, object positioning, and object control. The geometric curve here refers to a basic vector shape or a combination of basic vector shapes strictly defined by parameters and formulas, such as straight lines, circles, ellipses, triangles, rectangles, etc. For the detection of geometric curves, the most widely used is the Hough transform and its extension. [0003] The detection effect of the Hough transform and its generalization depends on the shape of the detected figure and the quality of the input data. Generally speaking, the detection effect...
