Pulp and paper enterprise

3

Problems• laborious process of definition specks paper •time expenditures•measurement error• loss of profit

4

Research purpose

Automation of the process of products specks definition in the pulp and paper industry, aimed at reducing defects of finished products and production processes complexity.

5

Tasks• To set up an algorithmic support for solving the problem of

definition specks paper • To select a software environment for the quality control

process automation in the pulp and paper industry • To employ proposed algorithms in the developed

environment using LabVIEW• To test the automated system• To study components for development of mobile applications

based on approved algorithms

Generalized algorithm of specks paper definition

7

Algorithm of the pixels density calculating

8

Algorithm of the image cutting

9

Algorithm of specks sorting

10

Program interface is designed using the LabVIEW software

11

Mobile application

Technology is in using camera on smart phones to make a photo of paper sample; then the application will download it and identifies specks using the approved algorithms

12

Results of research• The automated system is focused on the definition of the

indicator specks paper as one of the key indicators of quality• Accuracy of determining the index specks depends on the

quality of the sample (roughness, presence of ferrous inclusions, etc.)

• At this stage, studies are needed to extend the functionality of the software, including the various figures to implement recognition by their shape (triangle, diamond, circle, line etc.).

• It is required to implement the calibration parameters sensitivity in the interface of the program

• It is necessary to study functions and menu items in mobile application
