Ground Truth Map

All Wi-Fi localization methods utilize maps of indoor environments, generated with computer vision and Wi-Fi antennae. This map will be processed to improve fidelity and optimize system performance.

Subtraction

Wi-Fi readings are given as a value out of 100.

To account for differences in antennae, readings are normalized.

We have a ground truth map of the normalized Wi-Fi readings at every point.

Find the Difference between a point on ground truth map and Reading.

Find the difference between ground truth map and reading at every point.

Find the total difference between ground truth map and reading by adding up the differences.

Find the total difference between the ground truth map and each Wi-Fi reading at every point on the ground truth map.
