Method for maintaining mechanical apparatus based on analytics of surface photographies

1. A method for maintaining mechanical equipment with surface damages on at least one component or part of the mechanical equipment, the method comprising:

taking at least one photo of the at least one component or part;

processing the at least one photo to acquire geometric data of the at least one component or part;

comparing the geometric data acquired with criteria, the comparing including

comparing the geometric data acquired with geometric features of various components or parts to identify types of the at least one component or part,

comparing the geometric data acquired with a standard geometrical shape of the at least one component or part to calculate a material loss, and

comparing the geometric data acquired with permissible location and length of cracks for the at least one component or part; and

giving relevant instructions to the at least one component or part to reach the criteria.

2. The method of claim 1 , wherein after the comparing of the geometric data acquired with the geometric features and before the comparing of the geometric data acquired with permissible location and length of cracks, the method further includes identifying the location of the at least one component or part in the mechanical equipment.

3. The method of claim 2 , wherein, in the identifying, the location of the at least one component or part in the mechanical equipment is identifiable by scanning marks on the at least one component or part.

4. The method of claim 2 , wherein, in the identifying, the location of the at least one component or part in the mechanical equipment is identifiable by comparing the data with the geometric features of the at least one component or part.

5. The method of claim 1 , wherein, after the giving of the relevant instructions, the method further includes sending at least one of the relevant instructions and the geometric data acquired to a server.

6. The method of claim 5 , wherein, the method is implemented by an evaluating and measuring device.

7. The method of claim 6 , wherein the evaluating and measuring device includes mobile electronic equipment.

8. The method of claim 1 , wherein, in the taking of the at least one photo, the photo is taken by one or more cameras, and in the processing, comparing and giving, all performed by mobile electronic equipment, the photo is processed, compared with the criteria, and the component or part that reaches the criteria is indicated.

9. The method of claim 7 , wherein the mobile electronic equipment is a smart phone or tablet.

10. The method of claim 8 , wherein the camera is a stereo camera or a camera lens.

11. The method of claim 5 , wherein, after the sending, the method further includes analyzing the at least one of the relevant instructions and the geometric data acquired, on the server.

12. The method of claim 11 , wherein, after the analyzing, the method further includes updating the criteria.

13. The method of claim 5 , wherein after the sending, the method further includes providing a quotation or clarification for replacement parts.

14. The method of claim 5 , wherein after the comparing of the geometric data acquired with the geometric features and before the comparing of the geometric data acquired with permissible location and length of cracks, the method further includes identifying the location of the at least one component or part in the mechanical equipment.

15. The method of claim 14 , wherein, in the identifying, the location of the at least one component or part in the mechanical equipment is identifiable by scanning marks on the at least one component or part.

16. The method of claim 14 , wherein, in the identifying, the location of the at least one component or part in the mechanical equipment is identifiable by comparing the data with the geometric features of the at least one component or part.

17. The method of claim 8 , wherein the mobile electronic equipment is a smart phone or tablet.
