Problems solved by technology

However, because the existing method uses fixed coordinates (that is, the coordinates of the pre-estimated image are directly cropped), only one product can be detected at a time, and the efficiency is low, and the detection of the correlation of multiple product information cannot be realized.

Embodiment 1

[0047] Embodiment 1 of the present invention provides an intelligent cutting method, such as figure 1 As shown, the method specifically includes:

[0048] Step 101, acquire an image to be cropped, and use the acquired image as an image to be cropped;

[0049] Specifically, the image that needs to be cropped can be an image obtained by taking a photo with a camera, or a frame of image in a video, and the format of the image that needs to be cropped can be BMP, JPG, etc. In this embodiment, the image that needs to be cropped The source and format of the images are not specifically limited.

[0050] Step 102, processing the image to be cropped to obtain a binarized image of the image to be cropped;

[0051] Specifically, the processing of the image to be cropped includes, but is not limited to, binarization, which depends on the format of the image to be cropped. For example, if the image to be cropped is a grayscale image, the image to be cropped is binarized to obtain The bi...

Embodiment 2

[0089] Embodiment 2 of the present invention provides an intelligent cutting method, such as Figure 6 As shown, the method specifically includes:

[0090] Step 201, acquiring an image that needs to be cropped;

Abstract

The invention discloses an intelligent cutting method and belongs to the field of image processing. The method comprises the steps of acquiring an image to be cut, processing the image to be cut to obtain a binary image, acquiring a quadrangular contour in the binary image, calculating the mapping relation according to the quadrangular contour and the size of a target image, conducting mapping processing on the image to be cut according to the mapping relation to obtain a mapping image, and cutting the mapping image according to the size of the target image to obtain the target image. By means of the intelligent cutting method, a plurality of image regions can be recognized and cut in one image.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an intelligent cropping method. Background technique [0002] In the production and management process of information security products, some information of the products needs to be tested. In the prior art, in order to improve the efficiency of production management, the detection method includes taking pictures of products, and using OCR (Optical Character Recognition, Optical Character Recognition) technology to realize intelligent recognition and detection of product information. However, because the existing method adopts the method of fixed coordinates (that is, the coordinates of the pre-estimated image are directly cropped), only one product can be detected at a time, the efficiency is low, and the detection of the correlation of multiple product information cannot be realized. Contents of the invention [0003] The purpose of the present invention is to provide an inte...
