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. Subpic1.jpeg

To account for differences in antennae, readings are normalized. Subpic2.jpg

We have a ground truth map of the normalized Wi-Fi readings at every point. Subpic3.jpg

Find the Difference between a point on ground truth map and Reading. Subpic4.jpg

Find the difference between ground truth map and every point Subpic5.jpg
