Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0028] Since the inclination angle of the image needs to be known before performing angle calibration on the image, this embodiment of the present application provides a method and device for determining the inclination angle of the image.

[0029] In one embodiment of the present application, a method for determining information is provided, the method comprising:

[0030] Determining a first straight line and a second straight line perpendicular to each other in the plane where th...

Abstract

The embodiment of the present application provides a method and device for determining information, including: determining the first straight line and the second straight line perpendicular to each other in the plane where the edge image is located; obtaining the projection points of the edge pixel points of the edge image on the first straight line The first length of the longest line segment formed, and obtain the second length of the longest line segment formed by the projection points of the edge pixel points on the second straight line; according to the first slope determined by the first length and the second length and the second Slope, obtain the third straight line and the fourth straight line that are perpendicular to each other in the plane; respectively obtain the number of projected pixels of the first straight line, the second straight line, the third straight line and the fourth straight line; determine the obtained projected pixel number The maximum value is the first quantity; the inclination angle of the edge image is determined according to the first inclination angle. The inclination angle of the edge image can be determined by applying the solution provided by the embodiment of the present application.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an information determination method and device. Background technique [0002] Today, with the rapid development of artificial intelligence technology, image recognition and processing play an important role. However, the actual captured or scanned images often have a certain angle of inclination. If the angle calibration is not performed, it will cause great interference to the subsequent image processing. Before performing angle calibration on the image, the inclination angle of the image needs to be known, so that the image can be calibrated accurately. [0003] In view of the above situation, it is necessary to provide a method for determining the tilt angle of an image. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide an information determination method and device to determine the tilt angle ...
