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 every point
