The Google Maps Perception Extension is part of the Google Maps service, and this extension is required for Google Maps to function properly. The Google Maps Perception Extension powers lane-level features in Maps and processing of trip and sensor data. Google collects data through the extension for the purpose of monitoring the extension's health, and discovering and fixing bugs.
About collected data
The Google Maps Perception Extension uses location, camera, and Android sensor data to help Google Maps function. For example, it will detect lane line pattern, color, and distance from the vehicle, convert this to semantic notation and send it to Google. The data about lane lines is also used to keep Google Maps fresh and accurate to improve the user’s driving experience. Camera frames are not sent to Google.

- Usage like CPU and app memory
This data allows Google to discover and fix bugs, and is essential to the functioning of the extension.
