Education background:
* Industrial engineering
* Mechatronics
* Electrical engineering
* IT/Computer science


Level of thesis project: Bachelor thesis.

Number of students in the project: 1 student

Target:
This project is intended to improve linearization in measurement systems.

Background:
Epiroc’s Measurement technique group performs measurements and develops sensors and measurement methods.

One of our customized sensors has a built-in linearization function based on a number of polynomials, which are placed at user defined points during a calibration process. At verification of the calibration the linearization is evaluated. If the errors are considered to be too large, another set of points can be selected and the calibration restarts. This iterative method is not optimal and can be time consuming.

Another sensor reads a repetitive pattern and calculates a position with significantly higher resolution than the pattern. Today, calibration of the linearization is performed in a test setup.

Mission:
Your first mission is to develop an automatic linearization method based on the raw values from a large number of points and the relationship to ground truth. The method shall find the optimal points for the linearization polynomials resulting in a minimized linearization error.

Your second mission is to develop an automatic linearization method for the repetitive pattern that at best can be performed during operation without the need for a separate test setup. This will include error estimation and finding the linearization function that globally minimizes the error in the operating range.
The work includes implementing the methods, evaluate them versus today's performance and report your work (written and oral).

This project will be considered a success when methodologies and tools to perform accurate calibration that reduce the linearization error, give an estimate of the overall error and speed up the calibration process are available.

Implementation is preferably performed in Matlab, but alternatives can be discussed.

Qualification:
We are looking for a Bachelor student with both theoretical and practical skills. The candidate needs knowledge in interpolation and estimation methods, programming, and Matlab.

How to apply:
