Abstract

A computing device reads an entire image of an object. The entire image is spliced by a plurality of part images. A user selects an area on the entire image. The computing device determines a first number of first pixel points between a center point of the selected area and a center point of each covered image. The converted images are part images that the selected area covers. The coordinate values of the center point of the selected area are calculated according to the first number of pixel points and a size of each pixel point of the entire image. The computing device calculates coordinate values of each point of a selected area according to the size of each pixel point and the coordinate values of the center point of the selected area.

Claims

1. A computing device, comprising:

a storage system;

at least one processor; and

one or more programs being stored in the storage system and when executed by the at least one processor, cause the at least one processor to;

read information related to an entire image of an object, which is spliced using more than one part image of the object, from the storage system, wherein the information of the entire image comprises a size of each pixel point of the entire image;

determine a first number of first pixel points between a center point of a selected area and a center point of each covered image according to the information of the entire image, wherein the covered image is a part image that is covered by the selected area;

calculate coordinate values of the center point of the selected area according to the size of each first pixel point and each first number of the first pixel points between the center point of the selected area and a center point of each covered image;

receive measurement tools and a selected feature on the entire image; and

determine a second number of second pixel points between each point of the selected feature and the center point of the selected area, and calculate coordinate values of each of the points of the selected feature according to the second number of the second pixel points, the size of each second pixel point, and the coordinate values of the center point of the selected area.

2. The computing device as described in claim 1, wherein the information of the entire image further comprises information of the center point of each part image, a size of the entire image, and a resolution of the entire image.

3. The computing device as described in claim 1, wherein the size of each pixel point includes a size on an X-axis and a size on a Y-axis.

4. The computing device as described in claim 1, wherein the selected feature is selected from a group consisting of a point, a line, and a circle.

5. A computing device-based method for measuring images of an object, comprising:

reading information related to an entire image of an object by a computing device, the entire image being spliced using more than one part image of the object, from a storage system of the computing device, wherein the information of the entire image comprises a size of each pixel point of the entire image;

determining a first number of first pixel points between a center point of a selected area and a center point of each covered image by the computing device according to the information of the entire image, wherein the covered image is a part image that is covered by the selected area;

calculating coordinate values of the center point of the selected area according to the size of each first pixel point and each first number of the first pixel points between the center point of the selected area and a center point of each covered image;

receiving measurement tools and a selected feature on the entire image; and

determining a second number of second pixel points between each point of the selected feature and the center point of the selected area, and calculating coordinate values of each of the points of the selected feature according to the second number of the second pixel points, the size of each second pixel point, and the coordinate values of the center point of the selected area.

6. The method as described in claim 5, wherein the information of the entire image further comprises information of the center point of each part image, a size of the entire image, and a resolution of the entire image.

7. The method as described in claim 5, wherein the size of each pixel point includes a size on an X-axis and a size on a Y-axis.

8. The method as described in claim 5, wherein the selected feature is selected from a group consisting of a point, a line, and a circle.

9. A non-transitory storage medium having stored thereon instructions that, when executed by a processor, cause the processor to perform a method for measuring images of an object, the method comprising:

reading information related to an entire image of an object, which is spliced using more than one part image of the object, wherein the information of the entire image comprises a size of each pixel point of the entire image;

determining a first number of first pixel points between a center point of a selected area and a center point of each covered image according to the information of the entire image, wherein the covered image is a part image that is covered by the selected area;

calculating coordinate values of the center point of the selected area according to the size of each first pixel point and each first number of the first pixel points between the center point of the selected area and a center point of each covered image;

receiving measurement tools and a selected feature on the entire image; and

determining a second number of second pixel points between each point of the selected feature and the center point of the selected area, and calculating coordinate values of each of the points of the selected feature according to the second number of the second pixel points, the size of each second pixel point, and the coordinate values of the center point of the selected area.

10. The non-transitory storage medium as described in claim 9, wherein the information of the entire image further comprises information of the center point of each part image, a size of the entire image, and a resolution of the entire image.

11. The non-transitory storage medium as described in claim 9, wherein the size of each pixel point includes a size on an X-axis and a size on a Y-axis.

12. The non-transitory storage medium as described in claim 9, wherein the selected feature is selected from a group consisting of a point, a line, and a circle.
