Abstract

The present invention discloses a method for adsorbing a straight line/line segment in an image, including: presetting a straight line/line segment, dragging the straight line/line segment by selecting a first part of the line segment, and when a second part of the straight line/line segment is dragged to the vicinity of a line segment in an image, setting the preset line segment to be superposed with the line segment, the vicinity referring to that a minimum distance between the second part of the straight line/line segment and the line segment meets a preset rule. In the present invention, by means of the foregoing technical solution, a user can be conveniently assisted, according to a line segment that exists in an image, to define a polygon frame, so that subsequent image processing can be conveniently performed.

Claims

1. A method for adsorbing a straight line/line segment in an image, comprising:

displaying, by a device comprising a processor, a preset straight line/line segment;

dragging, by the device, the straight line/line segment when a first part of the straight line/line segment is selected and moved, and

when a second part of the straight line/line segment is in the vicinity of a detected line segment in an image, setting the preset straight line/line segment to be superposed with the detected line segment, wherein the vicinity refers to that a minimum distance between the second part of the straight line/line segment and the detected line segment meets a preset rule.

2. The method for adsorbing a straight line/line segment in an image according to claim 1, wherein the first part selected in dragging the preset line segment is either on the preset straight line/line segment or in the vicinity of the preset straight line/line segment.

3. The method for adsorbing a straight line/line segment in an image according to claim 1, wherein the first part selected in dragging the preset straight line/line segment and the second part on the straight line/line segment are a same part or different parts.

4. The method for adsorbing a straight line/line segment in an image according to claim 1, wherein the second part comprises at least one of the following cases:

an endpoint of the preset line segment;

a midpoint of the preset line segment; and

a point, having a minimum distance from any position on a line segment in the image, on the preset straight line/line segment.

5. The method for adsorbing a straight line/line segment in an image according to claim 1, wherein the preset rule is that a distance is less than a preset value, or is that a distance meets a preset formula.

11. An apparatus for adsorbing a straight line/line segment in an image, based on a mobile communication data terminal platform, and adopting the method for adsorbing a straight line/line segment in an image according to any one of claims 1 to 10.

6. A method for adsorbing a straight line/line segment in an image, comprising:

displaying, by a device comprising a processor, a preset straight line/line segment;

dragging, by the device, the straight line/line segment by selecting a first part of the straight line/line segment, and

when dragging ends, a second part of the straight line/line segment is in the vicinity of a corresponding second part of a detected line segment in an image, setting the preset straight line/line segment to be superposed with the detected line segment, wherein the vicinity refers to that a minimum distance between the second part of the straight line/line segment and the detected line segment meets a preset rule.

7. The method for adsorbing a straight line/line segment in an image according to claim 6, wherein the first part selected in dragging the preset line segment is either on the preset straight line/line segment or in the vicinity of the preset straight line/line segment.

8. The method for adsorbing a straight line/line segment in an image according to claim 6, wherein the first part selected in dragging the preset straight line/line segment and the second part on the straight line/line segment are a same part or different parts.

9. The method for adsorbing a straight line/line segment in an image according to claim 6, wherein the second part is a point, having a minimum distance from any position on the line segment in the image, on the preset straight line/line segment.

10. The method for adsorbing a straight line/line segment in an image according to claim 6, wherein the preset rule is that a distance is less than a preset value, or is that a distance meets a preset formula.
