### TIME DELAY DATABASE

AND ECULIDEAN DISTANCES

Goals from last milestone:

Choose between Excel or Matlab to use for Database.

Done! We wrote code for a Matlab Database.

Write code for Euclidean distance.

Done!

3) Achieve localization.

In-Progress.

4) Construct or use a GUI tool to display coordinate values.

In-Progress.

• For each sample point in the Test Space (180 Total)

• Receive Onset values from each mic- 4 total

• Use Onset values to get the abs. difference

• Create a 1 dimensional (9 element array)

• Create the 9 element array

• (x coordinate, y coordinate, z coordinate)

• Difference between Onset 1 and Onset 2

• Difference between Onset 1 and Onset 3

• Difference between Onset 1 and Onset 4

• Difference between Onset 2 and Onset 3

• Difference between Onset 2 and Onset 4

• Difference between Onset 3 and Onset 4

• For each sample point.( 180 points)

• (x, y, z, ab, ac, ad, bc, bd, cd)

• Write the array in the database

• Continue the loop!

• Once Database is complete, modify it for real-time and Euclidean distance.
